Find out more about how we test. When you're the gold standard for business notebooks, you have to do everything in your power to stay on top. And Lenovo is doing just that with the ThinkPad T430 $1,124 as tested, which adds a new Precision Keyboard and enhanced Dolby audio. Plus, the 9-cell battery inside this workhorse promises epic endurance to go along with Ivy Bridge muscle. Is the ThinkPad still the king?DesignTaking a "if it ain't broke, don't fix it" approach, the Thinkpad T430's lid is outfitted in the durable, yet extremely comfortable, black soft-touch finish. Other mainstays include strong chrome hinges and the Lenovo and Thinkpad insignias in the top left and right the lid via the sliding latch along the front lip of the notebook continues to be a breeze. Inside, you'll see the familiar bright red trackpoint in the center of the new island-style keyboard. Volume controls and a royal blue ThinkVantage button sit atop the keyboard along with a black power button. Just below the keyboard rests a touchpad flanked by discrete mouse buttons. A fingerprint reader sits to the right of the its 9-cell battery, the x x inch T430 is on the heavy side of the thin-and-light notebook category. It easily outweighs the x x inch Dell XPS 14, though this ThinkPad weighs the same as its predecessor. Nevertheless, the T430 can still slip in and out of a messenger bag or backpack with relative previous ThinkPad T Series notebooks, the T420 is designed to last. The rubberized ABS plastic lid, carbon-reinforced bottom and internal roll cage help protect against shocks and drops. In addition, 2012 models are reinforced with carbon fiber for enhanced strength and stiffness. The ThinkVantage Active Protection stops the hard drive when it senses a change in and AudioThe 14-inch, 1366 x 768p, 147 lux display isn't very bright, 40 lux short of the 187 thin-and-light category average. This is somewhat disappointing, given that the previous model, the T420, had a much brighter 230-lux screen, and a higher resolution of 1600 x 900. Fortunately, that screen is also available on the T430, a $50 option we highly the matte display on the T430 delivered sharp, crisp text on and Viewing angles were decent, with clear images from 45 degrees to the left or right of the to Dolby Advanced Audio technology, the speakers flanking the keyboard delivered fairly loud, rich audio. On George Michael's "Freedom," warm piano chords and a crisp drumline cascaded gently over Michael's rebellious tenor. Of the four presets in the control panel Movies, Music, Gaming we found that Movies was slightly louder, but Music delivered a richer sound. When we switched to the Gaming preset, the vocals sounded a little hollow and and TouchpadInstead of the classic keyboard we've come to know and love on the ThinkPad, the T430 features an island-style Precision Keyboard. Our concerns were immediately allayed, as the matte black, smile-shaped keys had plenty of space and provided firm, springy feedback. The keyboard on this notebook feels better than the AccuType layout on the IdeaPad series as well as other ThinkPads we've tested with island-style keyboards, such as the Lenovo ThinkPad only thing preventing the T430 from offering a perfect typing experience is the plastic palm rest. We'd prefer a soft-touch surface. Like the X230, Lenovo offers an optional backlit keyboard. It doesn't cost anything x touchpad is small, but pleasant to use. We liked the feel of the small raised dots of the touchpad against our fingers. Multi-touch gestures such as pinch-to-zoom, two-finger scroll, rotate and press were swift and responsive as were three-finger press and four discrete mouse buttons provided nice tactile feedback, even the smaller two buttons that sit on the angled front lip of the machine. The bright red pointing stick made for accurate, zippy movement. Almost too zippy-we had to dial down the speed in settings so as not to over-shoot our target. The rough texture of the nub firmly grabbed our finger, eliminating worries about How to Pick a Good Notebook KeyboardHeatAfter watching a full-screen video on Hulu for 15 minutes, the T430's touchpad measured 76 degrees Fahrenheit. That's well below the 95-degree comfort threshold of what we consider uncomfortable. The space between the G and H keys and the bottom of the notebook were also fairly mild at 78 and 83 degrees, fluorescent light, images and video captured via the T430's 720p webcam were a touch grainy, and colors were a bit washed out. Color accuracy improved under natural lighting, but the graininess left side of the T430 houses a pair of USB ports new for this model, a DisplayPort, VGA and a combination headphone/microphone jack.

However, thanks to the Intel HD Graphics 4000 GPU, you will be able to watch HD video and play "World of Warcraft" when the mood 3DMark11, the T430 notched a score of 624, fairly below the 757 category average.

That's certainly playable, but this frame rate falls below the 51 fps thin-and-light average. When we cranked the settings to maximum, the T430 dropped to an unplayable 19 fps, below the 26 fps looking for more graphics power will want to spring for Nvidia's NVS 5400M GPU with 1GB of RAM and Optimus Technology, but it's a steep $ LifeDuring the LAPTOP Battery Test continuous Web surfing over Wi-Fi, the Lenovo ThinkPad T430's 9-cell battery lasted a whopping 13 hours and 25 minutes.

The majority of the utilities, such as Password Manager and Enhanced Backup and Restore, handle maintenance and security and can be found under ThinkVantage ThinkVantage Fingerprint software was one of the more helpful programs, allowing us to quickly scan our fingerprints to unlock the notebook.

How we test computers Tech Computing Lenovo ThinkPad T420 I started with CNET reviewing laptops in 2009. Now I explore wearable tech, VR/AR, tablets, gaming and future/emerging trends in our changing world. Other obsessions include magic, immersive theater, puzzles, board games, cooking, improv and the New York Jets. My background includes an MFA in theater which I apply to thinking about immersive experiences of the future. Expertise VR and AR, gaming, metaverse technologies, wearable tech, tablets CredentialsNearly 20 years writing about tech, and over a decade reviewing wearable tech, VR, and AR products and apps Compared with laptops seen at CES 2012-ultrabooks and other sleekly designed variations-the ThinkPad T420 is a dinosaur, from the outside, at least. Thick and bulky, with a keyboard studded with enough auxiliary buttons to look like a space shuttle control panel, the T420 is as old-school as a laptop can be. It's also solid as a tank; not a rugged laptop per se, but outfitted with a spill-resistant keyboard and magnesium roll-cage chassis that most laptops don't have. And it's got more ports and features than most laptops, fighting the currently popular minimalist style. The Good The ThinkPad T420 has several things going for it performance, plenty of ports, excellent battery life, and a very comfortable keyboard. The Bad The design of the bulky, business-oriented T420 is positively Stone Age. It's also priced well above similar consumer laptops. No HDMI, no USB The Bottom Line The Lenovo ThinkPad T420 is as straight-up and unassuming as a business laptop can be on the surface, souped up with faster performance, long battery life, and a flexible selection of ports under the hood. The ThinkPad T420 is the laptop that escaped from your IT department, and might even be sitting on your desk as we speak. Lovers of older laptop tech won't be disappointed a rubberized trackpoint sits in the middle of a set of thick, tapered keyboard keys, while large extra trackpoint-controlling buttons sit above the touch pad. You can light your keyboard with a top-mounted LED light next to the Webcam, thank you very much-no backlit keyboard here. Older ports are also here in force everything from eSATA to ExpressCard, and even FireWire, is included. And, obviously, there's an optical drive another feature frequently missing from laptops nowadays.It feels unfair to attack the design of the ThinkPad T420 too much, because it's clearly not meant for the average consumer-this vPro-equipped laptop is all business. However, we can ding the T420 a little on price our configuration's priced climbed above $1,000, although the ThinkPad T420 starts as low as $749 on Lenovo's Web site for an entry-level version with a Core i3 processor and fewer bells and as reviewed / Starting price $1,139 / $749 Processor Intel Core i5-2520M Memory 4GB, 1,333MHz DDR3 Hard drive 500GB, 5,400rpm Chipset Intel QM67 Graphics Nvidia NVS 4200M / Intel HD 3000 Optimus Operating system Windows 7 Professional 64-bit Dimensions WD inches Height inches Screen size diagonal 14 inches System weight / Weight with AC adapter pounds / pounds Category MidsizeThe last time we reviewed a ThinkPad T series was the ThinkPad T410 back in December 2010. In terms of design, nothing's really changed. The ThinkPad T420 is heavy, at pounds for a 14-inch laptop, and its body is nearly thick. Even so, the T420 isn't as hard to heft as you'd expect based on how it looks. What you gain here is durability, port selection, and a surprisingly good mix of speed and battery life. With its slightly faster-than-average Core i5-2520M CPU, the T420 rivaled Core i5 competitors in our benchmark tests, and the included Nvidia graphics are good enough to play a game like Street Fighter IV at medium settings. The battery life topped 7 hours in our CNET tests, besting the Apple MacBook you'd expect, the ThinkPad T420's keyboard is very comfortable it's the Lincoln Town Car of keyboards, or a comfy orthotic shoe. It may not be sexy, but damned if it isn't a great keyboard for writing. However, the plethora of additional and strangely laid-out function and teleconferencing buttons can overwhelm. The Esc and Delete keys are large, vertical, and elevated above the rest of the keyboard. That's odd, too, but not if you use ThinkPads. Overall, it feels like a command center, and clearly was meant to be thought of as touch pad isn't very wide for multitouch, but its stippled surface has great traction and sensitivity. Too many buttons above and below the pad may be good for accuracy in tight quarters like on planes, but they cramp the pad's real estate. Multitouch gestures are tough to pull off. Out of curiosity, I gave that red rubber trackpoint another try. I have to admit, there's something to appreciate in the trackpoint's simple efficiency, even its accuracy, but it's not for everyone, and the rubber point can throw off a hunt-and-peck touch-typer such as this is clearly a laptop made for those who don't want change, who want a laptop that looks the same on the outside as a product from several years ago. If you want change, get a ThinkPad Edge. At least the T420's extra vertical thickness has been well-used to stack ports-a DisplayPort sits above a USB port on one side, while USB ports and SD card/ExpressCard slots are stacked on the have always boasted good displays, and the matte-finish 14-inch display on this model was crisp and bright and easy to read. The 1,600x900-pixel resolution is a step up from the standard, offering finer text resolution and more screen real estate, without shrinking icons or menus too much. It also costs $50 as an upgrade over the standard 1,366x768-pixel display. The T420's hinges open the screen up a full 180 degrees from the base for extra stereo speakers are fine for videoconferencing or office functions, but this isn't a wonderful movie-watching laptop. Streaming Netflix movies looked a little washed-out. Then again, you're not supposed to be using a work laptop like this for movies and games, are you? In case you're curious, Street Fighter IV did play astonishingly well using the T420's Nvidia Optimus NVS 4200M graphics, running at frames per second at native 1,600x900 resolution.A high-def 1,280x720 Webcam and included audio optimization settings give the ThinkPad T420 a better-than-average set of teleconferencing tools, although most laptops these days are more than capable of some basic Skype, especially if you wear a headset with a mike.

The T420s is a lot lighter and compacter than the previously reviewed T420 despite the same 14 inch size. However, it also has to manage with a smaller 44 Wh battery. While the immediate predecessor of the T410s still had processors from the Arrandale generation, the latest Sandy Bridge generation is now used. Our test device has been given the name ThinkPad T420s 4174-PEG NV8PEGE and represents the top model of the series. Lenovo hasn't made cutbacks in configuration and installs a Core i7-2640M and a fast 160 GB SSD from Intel. The HD Graphics 3000 integrated in the processor is additionally backed by a dedicated Nvidia Quadro NVS 4200M with Optimus support. The entry level models however don't have this feature. The manufacturer only skimps in view of the memory configuration and equips the nearly 1800€ notebook with only 4 competition in the battle for the favor of financially strong corporate customers is enormous. The ThinkPad T420s has to face devices like the Dell Latitude E6420, as well as the HP EliteBook 8460p. Our comprehensive review is to clarify if Lenovo can ultimately keep the T420s looks considerably slimmer and less unwieldy than its otherwise largely identical brother, T420. This is due to a weight of about kg and an overall height reduction of about centimeters. Lenovo has also maintained the classic ThinkPad design in the newest scion of its notebook range. Its appearance is dominated by plain but extremely robust, black plastic, reinforced with carbon fiber and magnesium, as in the past. The manufacturing quality is almost immaculate. We couldn't find any irregular gaps or deficient material transitions. The case only responds to very high force with marginal warping. We would only have liked to see a somewhat higher stability above the DVD drive. But the given level is exceptionally good. The torsional stiffness of the display and chassis is also impressive despite the low thickness. Regardless of all good qualities, we noticed that there is still room for improvements. The stability and quality of a MacBook Pro case, milled from aluminum, is yet unreached. That would also look good on the T420s. The aluminum display hinges make a very high-end impression. They allow the notebook to be opened to 180 degrees. Moreover, they keep the lid in place without prolonged shaking on shaky surfaces. Nevertheless, Lenovo has accomplished pulling the hinges only so tight that the notebook can be opened and closed with one hand. The display's clamshell design, known from other ThinkPads, prevents foreign objects and dust from unintentionally penetrating the gap between the keyboard and screen. Since the display overlaps the case, damages can successfully be prevented. The chassis's diet didn't go without affecting the T420s' connectivity. Only three USB ports have now found room on the case. That is two less than on the T420. In return, one of them is USB compatible and another has an always-on function. External monitors or projectors can either be connected over VGA or DisplayPort. On the other hand, Lenovo has left out HDMI which sooner used in the private customer sector. While Gigabit LAN, a 4in1 card reader SD/SDHC/SDXC/MMC and a combined headphone and microphone jack are still available, the combined eSATA/USB port has been omitted in the T420s. Additional interfaces can be added via an optionally available docking station. Only little has changed in view of interface distribution. All interfaces that are primarily needed for stationary use are found on the rear. That effectively counteracts the cable mess on the desk. Users who simply want to quickly connect a USB flash drive, a memory card or a headset can continue to do so on the device's left. Lenovo has also taken care to place all ports far enough apart so that even protruding plugs won't obstruct any neighboring interfaces. The notebook has a MP webcam with an average quality for video conferences. Audio is recorded via an array microphone and can convince with a clear and well-to-understand recordings. The so-called ThinkLight is a nice gadget. It's a small LED light beside the webcam that is to facilitate the T420s' use in dark surroundings. As a business laptop, the T420s can also serve with more features There is a Kensington Lock to protect the device against theft and the built-in fingerprint reader can be used for securing the stored data. The corresponding software is included in the preinstalled ThinkVantage Display lock Left Vent, USB audio, card reader Rear Power socket, LAN, USB always-on USB DisplayPort, VGA, vent Right WLAN slider, DVD burner, Kensington LockCommunication The T420s almost leaves nothing to be desired in our configuration. The Intel Centrino Ultimate-N 6300 module supports all current WLAN standards up to and also transmits in the 5 GHz network. Three antennas ensure an extremely stable connection even in cases of weak wireless signals. A Centrino Advanced-N 6250 with WiMAX support is alternately version takes care of data sharing with smartphones or other mobile devices in all models. Optionally available, and also installed in our test device, is a WWAN module Ericsson F5521gw which is capable of GPS and UMTS, including high-speed data transmission via HSPA+. The user can achieve gross data speeds of up to 21 MB/s in download and MB/s in upload with the right rate. The SIM card slot is hidden in the battery compartment, as in the ToolboxSupplies Lenovo doesn't include anything more than a quick start guide, the power adapter and the battery. Neither a driver nor a recovery CD is found. However, the user can create these from the backup partition of the T420s. Of course, all drivers and the ThinkVantage Toolbox are preinstalled in state of delivery. Warranty While American customers only receive a one year warranty ex-factory, all German devices have a 3 year onsite manufacturer the T410s or the T420, the tested T420s has the same combination of keyboard, touchpad and trackpoint. We will briefly summarize the most important qualities here. Keyboard The ThinkPad's keyboard bids high typing comfort, even for longer texts, with its firm and clear pressure point, its generous key drop for a laptop and the agreeably shaped keys. Yielding doesn't become evident even under high pressure at all; however the noise level could be a bit lower. The user is sufficiently compensated for this by an impression of an accurate, mechanical quality with every pressed key. The swapped position of FN and the left CRTL key may irritate the user at the beginning - a peculiarity that ThinkPads have had for years. Trackpoint Also unusual for a few, but a welcome tradition for the series, is the red trackpoint in the keyboard's lower center. After some getting used to, the user won't want to live without it because it allows just as a precise as fast control of the mouse cursor. Lenovo has given the trackpoint two dedicated mouse keys and a mouse wheel replacement located directly beneath the space bar. Thus, the user doesn't have to stretch his fingers up to the touchpad's keys beneath it. The click noise is very pleasant and quiet without lacking precision. Touchpad The touchpad's surface has a rough and distinctly different feel than the rest of the surrounding case. The finger glides pleasantly and smoothly over it and can control the mouse cursor with great accuracy. Multitouch gestures are supported, but it lessens the space on the already small touchpad gets even more. The corresponding buttons do their job quietly and reliably. However, they couldn't quite keep up with the quality of the other input devices and make a somewhat flimsy impression. It's possible to switch between the trackpoint and the touchpad via the key combination FN+F8. Both inputs can also be used uses a non-glare WXGA++ screen in all ThinkPads of the T420s range. The 1610 format of the T410s' predecessor had to make way for a wider 169 aspect ratio. Consequently, the former resolution of 1440x900 has increased to 1600x900 pixels. Together with a diagonal of inches, this results in an extremely high pixel density of 131 dpi. Unfortunately, the screen's measured rates aren't very impressive. Despite a good and even brightness of averagely cd/m2 in the highest setting, the contrast only equals a disappointing 1541. The reason for this is the high black value of cd/m2, which quickly leads to a rather grayish reproduction of black hues. 253cd/m²255cd/m²249cd/m²257cd/m²270cd/m²260cd/m²259cd/m²266cd/m²259cd/m² Distribution of brightnessAU Optronics B140RW02Gossen Mavo-MonitorMaximum 270 cd/m² Nits Average cd/m²Brightness Distribution 92 %Center on Battery 270 cd/m²Contrast 1541 Black cd/m² AdobeRGB 1998 Argyll 3D sRGB Argyll 3D Display P3 Argyll 3DThe low viewing angle stability is also on a level that seems inappropriate for this price range. While there is at least a certain amount of leniency for the viewer on the horizontal plane, deviations of only a few degrees lead to clear image distortions vertically. Unfortunately, the T420s isn't an isolated case. Immediate opponents, such as the Dell Latitude E6420 or the HP EliteBook 8460p also have similarly poor angles ThinkPad T420sRegardless of the partly only average results, the notebook can also be used outdoors without problems because of the matt screen surface and strong backlight. Although we would have also liked to see a screen with higher contrasts, the displayed content nevertheless remains legible even in direct we look at the ThinkPad's color reproduction. Both Adobe RGB and sRGB can't be covered completely, and even the larger T520 scores better here. Thus, a higher quality, external monitor should be connected over the available display port for professional image to GHz via Turbo BoostLenovo delivers the ThinkPad T420s with Intel's second generation Core i5 and Core i7 processors. As the top model of the series, our test device is equipped with a Core i7-2640M which is currently the fastest mobile dual core CPU on the market. Thanks to SMT Technology, every core can process two threads at the same time. The processor, manufactured in a 32nm process, is based on the latest Sandy Bridge architecture and has a base clock of GHz. It can be increased up to GHz via Turbo Boost The QM67 chipset, which also supports the processor-embedded HD Graphics 3000, is on the mainboard. The manufacturer has additionally installed an Nvidia Quadro NVS 4200M in a few versions of the series. It is enabled during an operation using Optimus when needed. Lenovo has given the T420s only one RAM module with a capacity of 4 gigabyte. Consequently, the processor also only has a single-channel memory bus available. Users, who need a larger RAM capacity and want to tickle out even the last percent of performance from the laptop, can retrofit another module in the second slot. However, the ThinkPad wasn't noticeably slowed down by the lack of dual-channel operation in our benchmarks. The highlight of all configuration features is undoubtedly the big 160 gigabyte SSD from Intel. It promises a significant performance increase in the system benchmarks. We will examine to what extent the swift memory unit is noticeable in practical information Lenovo ThinkPad T420s 4174-PEG CPU Performance Thanks to the generous hardware configuration, the T420s' performance rates are convincing. We determined the processor's single thread performance with Cinebench R10. The i7-2640M only lags behind the fastest mobile CPU, the Core i7-2960XM, by about 10% with 4450/5468 points 32/64 bit. A remarkable score for a CPU with a TDP of only 35 watts, which is mainly due to the strong Turbo mode of up to GHz. Our T420s has to admit defeat to the quad core competitors in the Multithreading Test of Cinebench An i7-2630QM is faster by more than 50% in view of points. This disadvantage however only has a negative effect when highly parallel and extremely CPU-heavy applications have to be processed. Beyond that, only the Dell Latitude E6420 is available with a quad core among the immediate opponents in the 14 inch R10 Rendering Single 32Bit4450 Cinebench R10 Rendering Multiple CPUs 32Bit9793 Cinebench R10 Rendering Single CPUs 64Bit5468 Points Cinebench R10 Rendering Multiple CPUs 64Bit11700 Points Cinebench R10 Shading 32Bit5015 Cinebench R10 Shading 64Bit5385 Points Cinebench CPU Multi Points Cinebench OpenGL fps HelpGPU Performance The dedicated Nvidia Quadro NVS 4200M was used for our benchmarks. It is automatically enabled in graphics load thanks to Optimus Technology. Benchmarks concerning the Intel HD Graphics 3000 integrated in the processor can be found in our database. The NVS 4200M is based on the GF119 chip, manufactured in a 40 nanometer process, and is also embedded on the entry level card, GeForce GT 520M. It has 48 shader ALUs and supports the current DirectX 11 standard. Lenovo has given the graphics chip a 1 gigabyte DDR3 memory on a 64bit wide memory interface; the clock speed is 740/1480/800 MHz core/shader/memory. This is a bit lower than the manufacturers specification of 810/1620/800 MHz, which results in a performance loss of about 10%. As expected, the card places itself approximately on the level of the identically clocked GeForce GT 520M and reaches 4829 points in 3DMark06. We could determine 2298 points in the performance preset with the successor, 3DMark Vantage. 3DMark 05 Standard 9388 points3DMark 06 Standard Score 4829 points3DMark Vantage P Result 2298 points3DMark 11 Performance 572 pointsHelp Gaming Performance Is this enough to also render newer games smoothly? The answer is a clear "yes and no". The demo version of newly released-building strategy game Anno 2070, used in the test, was only smoothly displayed in 1024x768 pixels and low details with fps. Thus, the NVS 4200M is only slightly faster than the Core i7-2640M's embedded graphics chip in this case. We could select medium or high details in older or less demanding games, like Fifa 12, but gamers won't be satisfied with the T420s' graphics performance. low med. high ultraAnno 2070 2011 CAD Performance This shortcoming won't likely be as devastating for the target group. Although the Quadro products are based on the same GeForce GPUs from Nvidia, these cards are specifically optimized for professional applications, such as from the CAD field. The low raw performance in the case of the NVS 4200M can only be compensated to an extent as can be seen in our very demanding benchmark, SPECviewperf 11System Performance The T420s achieves extremely good results in the system benchmark, PCMark, thanks to the fast processor and the SSD hard disk. With a total score of 11911 points in the Vantage version, the HP EliteBook 8460p 7734 points can be surpassed by 54%. 3312 points in PCMark 7 is also a very strong score. Even some gaming notebooks, like the Samsung 700G7A, don't manage that. Only larger laptops with a quad core processor and a high-end GPU can achieve better results 7 Experience IndexProcessorCalculations per RAMMemory operations per performance for Windows graphics3D business and gaming hard diskDisk data transfer PCMark Vantage Result 11911 pointsPCMark 7 Score 3312 pointsHelp AS SSDMass Memory In contrast to the entry level versions, our T420s test model comes with a 160 GB Intel SSD 320 series. The drive delivers an excellent presentation with sequential transfer rates of MB/s in read and MB/s in write CrystalDiskMark It can also excel with SSD-typical access speeds of milliseconds read/write. Now even faster drives with a SATA III interface are on the market. However, the solid state drives from Intel are deemed to be particularly reliable and are therefore an appropriate choice for the business laptop. Lenovo has branched off almost 16 gigabyte from the total capacity of 160 gigabyte for the recovery partition. The remainder is available for the operating system and other applications on a shared drive. The data memory's speed is already impressing when the preinstalled Windows 7 Professional as the 64bit version is booted The system is ready for use in less than 30 seconds after pressing the power button. Program installations and starts are accelerated significantly compared with a conventional hard disk. Moreover, no noise is generated and it has a lower power consumption. The user however has to accept a smaller capacity and a higher price in Read MB/s Sequential Write MB/s 4K QD32 Write MB/s System Noise ThinkPad users have high demands in an escort for everyday business regarding the noise of their work device. The fan of the T420s is usually deactivated in idle and light office tasks. Consequently, the notebook works absolutely noiselessly thanks to the SSD drive. Unfortunately, this condition doesn't last very long when the hardware is loaded a bit more, for example by a flash video. Despite uncritical temperature rates, the fan is turned on after a few seconds. It rotates fairly quietly and consistently, but it hums along audibly anyway. On the other hand, the ThinkPad is mostly unobtrusive during full load. We couldn't measure more than dB A even during our stress test with Furmark and Prime95 - a very good rate. Up until now, hardly a comparable device remained similarly quiet during this load. Even the Dell Latitude E6420 with a weaker Core i3-2310M climbed up to dB A.

We could measure temperatures of only 22-27°C without load. The notebook hardly gets lukewarm even directly at the vent. The case temperatures increase clearly after longer hardware load induced by our stress test and reach up to 39°C on the top. The cooling system can however keep a pleasant 28°C upright in the wrist rest and touchpad area. The bottom heats up to a very high 51°C selectively, but remains on a acceptable level on average. The maximum temperature of up to 99°C on the GPU and 96°C on the CPU is bordering. However, no stability issues developed in our multi-hour stress test and the processor only throttled marginally from GHz to GHz. The processor and graphics card remained a lot cooler in a realistic load induced by Cinebench or Anno 2070. Consequently, the device's cooling capacity should also be suitable for a warm summer. °C103 °C100 °C86 F °C94 °C79 °C83 F °C83 F28 °C82 °C78 F Maximum °C = 103 FAverage °C = 88 F °C85 °C110 F51 °C124 F29 °C84 °C98 °C95 °C78 F29 °C84 °C90 F Maximum 51 °C = 124 FAverage °C = 94 F Power Supply max. °C = 130 F Room Temperature °C = 67 F Voltcraft IR-360+ The average temperature for the upper side under maximal load is °C / 88 F, compared to the average of °C / 85 F for the devices in the class Office.+ The maximum temperature on the upper side is °C / 103 F, compared to the average of °C / 94 F, ranging from to °C for the class Office.- The bottom heats up to a maximum of 51 °C / 124 F, compared to the average of °C / 98 F+ In idle usage, the average temperature for the upper side is 25 °C / 77 F, compared to the device average of °C / 85 F.+ The palmrests and touchpad are cooler than skin temperature with a maximum of °C / F and are therefore cool to the touch. ± The average temperature of the palmrest area of similar devices was °C / 82 F °C / F. Speakers The T420s has two small stereo speakers, which are hidden behind a lattice on the keyboard's left and right. Not much has changed in regards to the mediocre sound quality of other ThinkPad range models. Midranges could already only be played insufficiently from the small speakers, and we didn't notice any basses. Speech is rendered somewhat tinny, but intelligibly and without distortions providing the user doesn't exceed a low volume. Otherwise it is advisable to connect an additional sound system using the headphone out, which succeeded with good quality in the Consumption The ThinkPad T420s' power consumption isn't conspicuous. 10 to 16 watts in idle aren't a record for a laptop with Optimus support, but are within an acceptable limit. The power requirement clearly increases in full load. We could measure a maximum of watts in the unrealistic stress test with Prime95 and Furmark. In view of the installed hardware and the only marginal throttling, it's a good rate. The Dell Latitude 6420, which was even more energy efficient in idle, consumed a bit more despite a weaker processor in this case watts. The included 90 watt power adapter has a sufficient capacity to charge the battery even during 6 cell battery now only has a capacity of 44 Wh due to the T420s' slim case, while the T420 had 57 Wh. The laptop managed a battery runtime of over 6 hours in the Battery Eater Reader's test, which simulates the notebook's idle mode in minimum brightness. So about 2 hours more than the previous T410s. Surfing via WLAN also proves that the new Sandy Bridge range is more energy efficient than the former Arrandale processor with a battery life of almost 4 hours. The T420s can't hide its powerful hardware and had to give up after 42 minutes in Runtime Idle without WLAN, min brightness 6h 16min WiFi Surfing 3h 57min DVD 2h 55min Load maximum brightness 0h 42min Lenovo Thinkpad T420sLenovo hasn't really launched a new product onto the market with the T420s. No matter if it's the classic ThinkPad case design, the excellent input devices or the installed hardware, we have seen almost all of these model characteristics in the sister model, T420, or the previous T410s. Nevertheless, the T420s occupies a market niche that is supposed to especially address business customers with its combination of high performance components and high mobility. They will likely be pleased about a fast Core i7, an SSD drive and an extensive connectivity including UMTS/HSPA at a price of just under 1800€. The manufacturing quality and case stability is high-end, but is surpassed by a few competitors, such as the HP EliteBook 8460p. We noticed room for improvement in the fan management's fine-tuning and the built-in screen. The latter is suitable for outdoor use due to its matt surface and good brightness, but is very viewing angle dependent and has a disappointing black value. Overall, the Lenovo ThinkPad T420s earns itself a good, though not very good total score of 84%. In addition to the EliteBook 8460p from HP, the Dell Latitude E6420 could be a possible alternative. It can achieve a battery life of up to 12 hours due to an optional 9 cell battery. By courtesy of...

An invariable constant. The tried and tested Thinkpad design has practically remained untouched on the outside. But from now on, the new Sandy Bridge hardware does its job inside the T420. Moreover, the compact office laptop boasts with an excellent communication configuration for the professional has doubtlessly made a name for itself in the business field with the Thinkpad notebooks. The T-series wants to "offer the best security, manageability, services and support" according to Lenovo's homepage, and thus sets itself apart from the top of the significantly stronger W-series. In return, the X-series scores with a greater mobility. Our test device is the 14 incher from the T-series, called T420. Adjacently, the 15 inch model, T520, is also offered and in review at the same time. Essentially, the Tx20 laptops only differ from the previous models, called T410 and T510, by a hardware refresh to the new Sandy Bridge processors. The test device's full name is T420 4236-NGG. Inside an Intel Core i7 2620M CPU does its job. The incorporated graphics chip, Intel HD Graphics 3000, is exclusively available for video output in our test model. This configuration is supported by a four gigabyte DDR3 main memory and a fast 500 GB hard disk with a revolution speed of 7200 rpm. Aside from various Core i processors, the T420 is also available with a dedicated NVIDIA NVS 4200M graphics card and Optimus technology – at least in the USA. Consequently, the rating of performance contingent parts is dependent on the real configuration and can't necessarily be applied to other models. The Thinkpad T420 can practically be seen as an immediate opponent of the basically similarly configurable Latitude E6420 from Dell. While Dell has opted for a completely new design, Lenovo contrarily sticks to the tested and tried Thinkpad design for the Thinkpad T420. We will show to what extent both vying notebooks differ in or 15 inch, the looks have been maintainedAt first glance, The T420 doesn't seem to differ from the T410 much. But this is deceptive. For one thing, the display's diagonal has slightly shrunk from inches to 14 inches. The same applies for the laptop's height and width, whereas the depth has interestingly gained a bit. The measurements for comparison for the T420 and 32x336x239 for the T410. Albeit, as we will see in a moment, quite a few changes have been made on connectivity, Lenovo sticks to the proven, light clamshell design. No modifications can be found in color or material choice, either. The almost completely black case has been made from plastic. The haptics correspond to the choice of materials. However, the matt and slightly roughened surfaces don't feel unpleasant. The case's stability is basically satisfying. But it still shows the same weaknesses known from the T400. So, in the Ultra Bay slot's area and on the plastic cover above the keyboard. The case can yield somewhat and creak under selective display components stand up well to our warp and pressure tests. It hardly bends when the case is lifted up at its edges. The hinges are first give in before image distortions turn up under selective pressure. In return, the display bezel yields evidently when pressure is applied and allows image deviations to become visible. We like the metallic hinges that hardly teeter after adjusting the opening angle. Surprisingly, they don't cope well in shaky work conditions train journey. Since they are smooth and the base unit is sufficiently heavy, both single-handed opening and closing are possible. The maximum opening angle of even a bit more than 100 degrees doesn't cause any restrictions in any case. In addition to the clamshell design, the ramshorn hook contributes to safety during transportation. It keeps the device securely closed and can be opened easily with the slider on the front edge. Let's start with a tour around the device itself. We notice that the positioning favors right handed users a bit. Depending on the utilization of single ports, a few cables can gather on the left, which may considerably obstruct the work area on the laptop's left. Two of the five USB ports, the display port, the VGA and the RJ45 are found on the left's center edge. In opposition, Lenovo has taken care to place potentially permanently occupied ports, such as the other two USB ports and the eSATA/USB combo port, in the right's rear area in the interface arrangement. In addition, the right accommodates, from front to back, a combo audio socket, the optical drive in an Ultra Bay slot, a 4in1 cardreader that supports SD, MM, SDHC, SDXC, and an ExpressCard34 port. The rear is completed by a powered USB port and a RJ11 modem socket. The power adapter is also connected on the case's rear. To our regret, Lenovo forgets, like Dell in its E6420, to install a USB port in the course of the refresh. Although the eSATA interface also bids a higher data transfer rate than USB increasingly more external mass memories are being offered with USB ports and eSATA is disappearing little by little from the market. In comparison to the competition, we also notice that Dell relies on the utilization of a HDMI port in the E6420 and thus accepts the according restrictions. In opposition, Lenovo remains resolute in installing a display port directly on the device. Compared with its predecessor, the T410, hardly anything of significance has been changed. Merely a powered USB interface has been added. Moreover, the interface layout has been revised, but not really improved. So, if you find cables in the work area beside the laptop disturbing, or if you don't want to re-connect all the cables after mobile use, you can make use of a docking solution. The correlating docking port is, as usual, on the notebook's about docking stations – it remains interesting to see which docking solutions will find their way to Europe. Currently, two models are available for the T420 in the USA The ThinkPad Mini Dock Plus Series 3 US/Canada/LA -> manufacturer's information for about 250 US dollars. It allows connecting three additional external monitors in addition to the installed display. Secondly, the ThinkPad Port Replicator Series 3 -> manufacturer's information for about 280 Slider for opening Left Fan, VGA, RJ45 LAN, two USB hard disk slot Rear RJ11, powered USB, battery, power socket, fan Right Audio combo socket, optical drive, ExpressCard34, 4in1 cardreader, USB USB/eSATA combo port, Kensington Security slotCommunication Alike the T410, our T420 test sample scores with an extensive communication configuration. Everything that is useful and available is installed. A Bluetooth module version is optional, and installed in our test device. It allows data exchange with small, portable devices, such as PDA or mobile phones. Just as optional is a mobile broadband module F5521gw Mobile Broadband also installed in our Thinkpad. The correlating SIM slot is located in the battery compartment. The matching antenna cables are present so that a UMTS/HSPA module can be retrofitted later. In regards to WLAN, various options are given. An Intel Centrino Ultimate-N 6300 AGN agn module is in the test device. The laptop can be linked to Ethernet networks via the Intel 82579 LM Gigabyte Network Connection. Video conferences aren't a problem anywhere with the optional 720p HD camera and this configuration. Security In addition to the obligatory Kensington Lock, the T420 also has a fingerprint reader, among other things. A splash waterproof keyboard saves data from loss in case of mishaps with liquids. Supplies Besides the necessary paraphernalia, such as power adapter and battery, only a bit of printed information is included in the scope of delivery. The user should create recovery DVDs for the pre-installed Windows Professional 64bit immediately after purchase. This isn't a problem with the convenient ThinkVantage tool, though. Warranty The standard warranty for the T-range is three years in Europe. The basic warranty only includes a one year bring-in service in the USA. Various warranty extensions can be purchased Neither design nor layout has been modified in comparison to the T410. Apart from the exchanged STRG and FN keys, we are dealing with a standard layout with clearly arranged key grouping. The blue ThinkVantage key is again the most striking additional key. It opens the well arranged ThinkVantage tools, respectively a recovery process can be started while booting. Just left of it are a mute button for the speakers and microphone and a rocker for volume control. The keyboard's illumination is integrated in the upper display bezel, as it was in the T410. It can be turned on/off with the FN+PGUP keys. The light can help you find your way around the input devices in complete darkness, but it can't hold a candle to backlit keyboards in our opinion. Prolific typists will find the Thinkpad keyboard very pleasing due to its mechanical qualities, well dosed key drop and clear pressure point. Additionally, concave keys add to typing comfort. Unfortunately, the keyboard gets quite loud especially during energetic typing. Nevertheless, touch-typing isn't a problem right from the start. Touchpad and Trackpoint The similarities to the T410 are just as striking here. The touchpad and trackpoint can be independently disabled and enabled via F8+FN. The touchpad proves to have a pleasantly roughened surface with good gliding traits. The mouse cursor control is, again, accurately possible without problems and the multi-touch features respond as expected. Moreover, scrolling via scroll fields at the touchpad edge is also possible. The touchpad's borders can hardly be distinguished from the surrounding case due to a simple component correlating buttons need a bit of getting used to since they are on the beveled edge. They are smooth, respond well over their entire breadth and don't click too loud, either. Alternately, there is also a red trackpoint. It allows just as precise navigating of the mouse cursor. The correlating buttons are fairly quiet. There are no complaints in regards to functionality, of the 1610 format as in the T410, a 169 aspect ratio is now used. The display diagonal has been marginally reduced from inches to 14 inches. In return, the resolution has been increased from 1440x900 pixels to 1600x900 pixels. Thus, there are now so many pixels in the total height as in the previous model. However, the test device has gained a bit of width. As it isn't expected differently from a business device, the display surface has been AR coated. The device thus not only meets the requirements on display workstations, but also is more suitable for outdoor T420 has generally improved in comparison to the T410 in terms of assessments. It is brighter and illuminated more evenly. Merely the black value is slightly lower than in the prior model. Nevertheless, the better brightness results in a somewhat higher contrast. In contrast, the E6420 scores with a significantly higher maximum brightness of 320 cd/m2 and still cd/m2 on average. In return, Dell's laptop has to admit clear defeat in the field of black value and contrast. 197cd/m²190cd/m²214cd/m²213cd/m²223cd/m²221cd/m²210cd/m²198cd/m²194cd/m² Distribution of brightnessLEN40A1Gossen Mavo-MonitorMaximum 223 cd/m² Nits Average cd/m²Brightness Distribution 85 %Contrast 1621 Black cd/m² AdobeRGB 1998 Argyll 3D61% sRGB Argyll 3D Display P3 Argyll 3DAs you can see in the comparison pictures, which have been made with various ICC color profiles, The T420 hasn't been designed for professional image editing. AdobeRGB and sRGB aren't covered. Thus, it is in the same league as Dell's E6420 with the same display size and resolution. Differences in view of color reproduction become visible in comparison with especially high quality screens. They can be found, for example, in Apple's MacBook Pro 13 or in Dell's XPS 15. Even the T420's bigger brother, the T520, scores better an anti-reflective surface and an average brightness of over 200 cd/m2, which is also available in battery mode, the test model is pretty suitable for outdoor use. The display content even stays fairly legible in direct last point we look at for rating a screen is its viewing angle stability. It turns out to our satisfaction horizontally and the image can be recognized even in very narrow angles without ado. As usual in the majority of laptops, the viewing angles along the vertical plane are considerably lower in the T420. Consequently, you can take it for granted that frequent viewing angle adjusting will be necessary to ensure a well legible image, especially during outdoor use. When several people are looking at the screen at the same time, their eyes should be at about the same angles Lenovo Thinkpad T420 4236-NGGCurrently, various models with Core i5 or i7 of the second generation are being offered. To be exact, our test model was equipped with an Intel Core i7 2620M Sandy Bridge CPU. It is presently the fastest dual core processor from the Sandy Bridge family that was introduced at the beginning of 2011. It can process up to four threads at the same time thanks to Hyper Threading. The Turbo Boost technology allows single cores to overclock dynamically from GHz up to GHz, depending on load and cooling capacity. In comparison to the Arrandale processors, the turbo function has been improved among other information Lenovo Thinkpad T420 4236-NGG The DirectX 10 capable Intel HD Graphics 3000 chip incorporated directly in the processor is available for the video output in our test device. Thus, the graphics performance is about on par with an Nvidia Geforce 310M entry level card. Alike the Latitude E6420, models with an NVIDIA NVS 4200M and Optimus technology are listed in the USA. Our T420 has a four gigabyte DDR3 RAM available for the main memory. They are located on one single, inaccessible for the user, chip. Only a second, still unoccupied bank is accessible via the maintenance cover. An intended upgrade can easily be accomplished by the customer. Due to the 64bit Windows 7 Professional operating system, the four gigabyte of main memory can be exploited efficiently, in contrast to a 32 bit version, and there's nothing standing in the way of a RAM upgrade. The processor's memory controller can address a maximum of up to eight gigabyte of DDR3-1066/1333 7 Experience IndexProcessorCalculations per RAMMemory operations per performance for Windows graphics3D business and gaming hard diskDisk data transfer R10 Rendering Single CPUs 64Bit5438 Points Cinebench R10 Rendering Multiple CPUs 64Bit11507 Points Cinebench R10 Shading 64Bit5566 Points Help PCMark Vantage Result 7845 pointsHelp Both the processor as well as the application performance is unsurprisingly a bit higher than the E6420 equipped with a Core i3-2310M. The performance rates are according to the expectations on this hardware configuration. Our test candidate achieved a total score of 7845 points, which is especially due to its high communication sub score, in the PCMark Vantage test for rating the overall performance. Thus, it's even on par with stronger gaming machines, like the Asus G73SW GeForce GTX 460M, Intel Core i7 2630QM, in terms of application Performance Verdict The test device still can keep up with gaming machines like the Asus G73SW in regards to application performance. However, in view of the graphics hardware, it doesn't stand a chance in 3D performance as we expected right from the start. That is confirmed by the results in the Cinebench Shading Test and the various 3DMark benchmarks. Unfortunately, the test results are beneath those that would be expected for a HD Graphics 3000. However, since the power measurements always remain under par, we have to reckon with a defective device. Another indication for this is that the device detection of the ThinkVantage Tools fails regularly. In order to exclude a problem in the settings we checked the BIOS and the energy settings in Windows 7. We will attempt to attain a replacement device for an update review. We would refer to our detailed test of the Intel HD Graphics 3000 chip and to the HD Graphics 3000's spec sheet for more information. 3DMark 05 Standard 6131 points3DMark 06 Standard Score 3381 points3DMark Vantage P Result 1696 pointsHelp Transfer Rate Minimum MB/s Transfer Rate Maximum 102 MB/s Transfer Rate Average MB/s Our test device's hard disk is a ST9500420AS from Seagate. It has a gross capacity of 500 GBs, whereas a part is used as a hidden recovery partition. It achieves according results in HDTune and in CrystalDiskMark tests with a revolution speed of 7200 rpm. A DVD burner is also available as another mass storage device. To be precise, it is an Optiarc DVD RW Noise The T420 always remains fairly quiet regardless of the load. The system noise is a constant dBA in low load. The hard disk is slightly louder with dBA during test laptop just only reaches a maximum noise level of dBA during our stress test GPU and CPU in full load. The operating noise thus always stays at an acceptable level. The power consumption assessments 28W max however indicate that the processor doesn't exploit its maximum possible capacity even during the stress test. Monitoring the processor clock rate with the CPUZ tool recorded the default clock rate of GHz for the CPU in the stress test. This means, no overclocking of all four cores and the installed GPU during load. The CPU clocks with GHz when only Prime95 is activated. When Furmark is added, the system throttles down to GHz. We can also only record a maximum of GHz in Cinebench R10 Single Core rendering. The clock rate meter stays at the same level in multi core rendering. The i7-2620M's maximum possible clock rate of GHz is consequently not exploited in any tested state. Nevertheless, the benchmark results that are determined in Cinebench R10 stay within the i7-2620M CPU's expected range and don't show any irregularities in regards to a possible throttling.

This still applies for the entire upper surface even during higher load, for example two hours in the stress test. Merely temperatures above body temperature are measured in some places on the bottom, and a maximum of degrees Celsius in the vents' areas. The Core i7 2620M dual core processors' core temperatures inside climb to a maximum of 85 degrees Celsius inside. We must point out that the T420 in the configuration at hand hasn't been conceived for graphic-heavy applications, but for office and internet anyway. °C94 °C94 °C87 F °C96 °C96 °C87 F °C89 °C87 °C81 F Maximum °C = 96 FAverage °C = 90 F °C103 °C97 °C89 °C84 °C100 °C101 °C83 °C97 °C96 F Maximum °C = 103 FAverage °C = 95 F Power Supply max. °C = 131 F Room Temperature °C = 71 F Raytek Raynger ST± The average temperature for the upper side under maximal load is °C / 90 F, compared to the average of °C / 85 F for the devices in the class Office.+ The maximum temperature on the upper side is °C / 96 F, compared to the average of °C / 94 F, ranging from to °C for the class Office.+ The bottom heats up to a maximum of °C / 103 F, compared to the average of °C / 98 F+ In idle usage, the average temperature for the upper side is °C / 80 F, compared to the device average of °C / 85 F.+ The palmrests and touchpad are cooler than skin temperature with a maximum of °C / F and are therefore cool to the touch. - The average temperature of the palmrest area of similar devices was °C / 82 F °C / F. Speakers The speakers' quality isn't to be rated as high in an office laptop for professional use as in, for example, a multimedia notebook. In fact both stereo loudspeakers, on the keyboard's left and right, are basically suitable for voice. Music enjoyment doesn't turn up due to the tinny, bass-poor and treble-heavy sound. High quality headphones, connected to the mm audio combo socket, can remedy this. The signal is transmitted clearly, undistorted and static-free in the test audio test only, no measurement.Our test model is at the start with a 57 Wh, 6 cell lithium ion battery in this test. One possibility of extending the battery life is ordering the 9 cell battery. Another is the docking of a 9 cell battery. According to the manufacturer's specs, a total maximum battery life of up to 30 hours is possible. In any case, a maximum battery life short of "only" seven and a half hours is possible with the battery at hand. BatteryEater's Reader's Test determined this runtime in minimum brightness, with disabled wireless module and in energy saving mode. This rate is unrealistic for practical use due to the low and unusable minimum brightness. We execute the WLAN test in a useable brightness, so from level 12 to 15. We can do research on the internet for up to six hours, also in energy saving profiles, in this low load scenario no flash videos. Movie enjoyment ended after a bit less than three hours in the DVD test. It is executed in maximum brightness and disabled wireless modules, as well as in "Video" mode. The battery life nosedives in 3D intensive applications, maximum brightness, enabled wireless modules and maximum performance mode. The BatteryEater Classic test simulates an OpenGL calculation for us and records a minimum battery life of only about an Runtime Idle without WLAN, min brightness 7h 28min WiFi Surfing 5h 59min Load maximum brightness 1h 06min The Latitude E6420 clearly has the lead in the battery tests due to its larger 9 cell battery. Our test laptop's runtimes are nevertheless remarkable in relation to the battery's capacity. That is especially due to the fairly low power consumption. It is a bit lower than that of the E6420 with to watts in idle mode. Surprisingly, the maximum power consumption wasn't as high as expected in the stress test 100% CPU and GPU load. Solely the CPU proves to have a maximum power loss of 35 watts. However, our meters only recorded watts for the entire system. Thus, we checked the setting in Lenovo's PowerManagement in Windows 7 and the BIOS settings. But we didn't find anything in neither place. The settings for mains operation are clearly set to "Maximum Performance" in the BIOS. At any rate, the T420 is also available with a dedicated NVIDIA NVS 4200M graphics card in the USA. The Optimus technology is thus used to keep the power consumption low during low load. Since our E6420 test device is equipped with the NVIDIA NVS 4200M graphics card and Optimus option, our T420 has a clear advantage in power consumption during load Thinkpad T420Apart from the expected performance increase due to the new processor generation, many things tried and tested things have been maintained. This is just as true for the case as for the pre-installed, convenient ThinkVantage tools. Slight modifications and upgrades can be found in the connectivity. Nevertheless, the user still has to live without USB In return, an eSATA/USB port has been installed. The test laptop's communication configuration is comprehensive. All available options are exploited broadband module, Bluetooth version WLAN with standard n support and gigabit Ethernet. We like the 14 inch screen that is marginally smaller than the T410's display diagonal. The desktop's layout has been maintained, respectively even slightly improved in width due to a resolution of 1600x900. There's nothing standing in the way of mobile use with the matt display surface and good brightness. However, the T420 only bids standard fare in terms of color reproduction. According to the manufacturer, a battery life of up to 30 hours are supposed to be possible with the 9 cell system battery and additionally docked 9 cell battery slice. We achieved a plausible battery life of up to 6 hours with our 6 cell battery with a capacity of 57 Wh WLAN test. The T420 has basically been designed for business customers who are looking for a solid office laptop with a good application performance and nevertheless good mobile qualities. A slight performance increase in 3D applications can be expected in the configurations with a dedicated Nvidia NVS 4200M graphics card, which also supports DirectX 11, listed in the USA. However, our test laptop won't mutate to a stronger graphics workstation even with this graphics solution. By courtesy of ...

It has the battery life, usability and build quality it takes to get work done around campus. The option of configuring either a budget level laptop of around $800 or high-end laptop configuration of $1,400+ is great and allows you to design a laptop that fits your needs, but still get the same build and design quality no matter what you include. I like the fact the option for a higher resolution screen is present, for those of us that find we can do work more efficiently using two windows open at once on the screen you will appreciate the 1600 x 900 resolution screen.

It goes against the grain of today’s laptops in many ways. It’s not stylish, it’s not thin, and it’s not light. The touchpad is a bit of an afterthought, functional but obviously playing second-fiddle to the trackpointer.

In addition to desktops and notebooks, the company also produces monitors, projectors, servers, etc. In 2011, Lenovo acquired the majority of Medion AG, a European computer hardware manufacturer. In 2014, Lenovo took over Motorola Mobility, which gave them a boost in the smartphone market. From 2014 to 2016 Lenovo's market share in the global notebook market was 20-21%, ranking second behind HP. However, the distance decreased gradually.

TechRadar Verdict Pros +Excellent performance+Great keyboard+Good build quality+Sharp screen+160GB SSD Cons -Price-Battery life-Gets quite hot Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test. In a nutshell, the Lenovo ThinkPad T420s is a powerful business portable that's a pleasure to use, but not exactly a looker. With its contourless, black plastic body and sharp edges, it looks like it has climbed straight out of the it up and things improve. The inside is still black, but there's a large keyboard, a host of function buttons which adorn the top, and a large textured track pad. The focus is on usability, so the mouse pad has two sets of buttons, two above and two below. It's also light at keyboard is extremely comfortable to use. It's easy to really get to grips with and we were firing out long documents without mistakes after a few hours. The cushioning on the keys is incredible, and it feels the closest to a proper keyboard we've seen on a track pad feels natural to use, and we reserve special praise for Lenovo for keeping the mouse buttons basic and functional. The screen is a matte-finished 1,600 x 900 panel, which is packed into the 14-inch frame. It's a great non-reflective panel that's ideal for working outside and in direct sunshine. What's more, it's really sharp, if a little pale, so you can still enjoy a movie on long business trips, even if it's not a great media laptop for the the powerInside the Lenovo ThinkPad 420s is plenty of power, which makes this a business laptop suited to people who need real grunt for demanding applications. The Intel Core i7 2640M is clocked at a whopping making it one of the most powerful processors in Intel's Sandy Bridge our lab tests, the T420s flew, topping out with a score of 11700, which is nearing gaming PC performance. This means you can run the most demanding programs, multitask demanding applications, while simultaneously surfing the web and transferring large files. If you're the kind of person whose toolbar is packed with tabs, you need this level of computing the T420s has 4GB of RAM, which is standard for modern laptops, and a 160GB SSD drive. SSD drives help the system feel responsive, start faster and are less prone to failures, which can be devastating. Normally these drives come in 120GB iterations, so it's great to see a bigger 160GB drive, which means you'll have more space for apps and life 125 minutesCinebench 117753DMark 2006 3800Despite all the praise, it's not all good for the Lenovo. There's a definite heat issue and battery life is also disappointing - you'd be lucky to get three hours office use away from the final issue is the price just over £1,500 is a serious outlay. While you do get top quality, you can get more for less. If you need a good business laptop, features such as encryption, fingerprint scanner and added security levels make it worth it. But if you're just looking for a powerful home laptop, the Asus X54E will serve you much better. Most Popular

Uma constante invariável. O design experimentado e testado do Thinkpad praticamente se manteve intacto no exterior. Mas a partir de agora, o novo hardware Sandy Bridge faz seu trabalho dentro do T420. Além disso, o compacto portátil de escritório ostenta uma excelente configuração de comunicações para o campo Lenovo sem dúvida criou um nome por si mesma no campo empresarial com os portáteis Thinkpad. A série T deseja "oferecer os melhores serviços de segurança, comodidade, serviços e suporte" se acordo com o web site da Lenovo, e, portanto, distingue-se do topo da série W significantemente mais forte. Em compensação, a série X pontua com uma mobilidade mais ampla. O nosso equipamento de teste é o de 14 polegadas da série T, chamado T420. Adjacentemente, o modelo de 15 polegadas, T520, também é oferecido e está em análise ao mesmo tempo. Essencialmente os portáteis Tx20 somente se diferenciam dos modelos anteriores, chamados T410 e T510, por uma atualização no hardware para os novos processadores Sandy Bridge. O nome completo do equipamento é T420 4236-NGG. Dentro dele um CPU Intel Core i7 2620M faz o seu trabalho. O chip gráfico incorporado, Intel HD Graphics 3000, esta exclusivamente disponível para a saída de vídeo em nosso modelo de teste. Esta configuração é suportada por uma memória de quatro gigabytes DDR3 e um veloz disco rígido de 500 GB com uma velocidade de rotação de 7200 rpm. Além de vários processadores Core i, o T420 também está disponível com uma placa de vídeo dedicada NVIDIA NVS 4200M e tecnologia Optimus – pelo menos nos EUA. Conseqüentemente, a valoração das partes contingentes do desempenho depende da configuração real e pode não necessariamente ser aplicado a outros modelos. O Thinkpad T420 pode ser praticamente visto como um oponente imediato do Latitude E6420 basicamente configurável se forma similar. Enquanto a Dell optou por um design completamente novo, a Lenovo contrariamente continua com o design experimentado e testado para o Thinkpad T420. Vamos demonstrar até que grau se diferenciam ambos os portáteis ou 15 polegadas, o visual foi mantidoA primeira vista, o T420 não parece de diferenciar muito do T410. Mas isto é enganoso. Por uma coisa, a diagonal da tela se reduziu de 14,1 polegadas para 14 polegadas. O mesmo se aplica para a altura e largura do portátil, sendo que a profundidade interessantemente aumentou um pouco. As medições para comparação 30,5x340,5x233mm para o T420 e 32x336x239 para o T410. Embora muitas poucas mudanças tenham sido feitas na conectividade, a Lenovo permanece com o design leve de concha. Nenhuma modificação pode ser encontrada nas opções de cores ou materiais. O case quase completamente preto foi feito de plástico. A sensação táctil corresponde à seleção dos materiais. No entanto, as superfícies mate e levemente ásperas nãos são desagradáveis. A estabilidade do case é basicamente satisfatória. Mas ainda mostra as mesmas deficiências conhecidas do T400. Portanto, na área do compartimento Ultra Bay e na coberta plástica sobre o teclado. O case pode ceder um pouco e ranger sob pressão seletiva. Os componentes da tela resistem bem os nossos testes de rigidez e pressão. Quando o portátil é levantado pelas bordas não se deforma quase nada. As dobradiças primeiro cedem antes que surjam distorções na imagem sob pressão seletiva. Em compensação, o marco da tela cede evidentemente quando é aplicada pressão e permite que os desvios da imagem se tornem visíveis. Gostamos das dobradiças metálicas que dificilmente se balançam depois de ajustar o ângulo de apertura. Surpreendentemente, elas não suportam muito bem as condições de trabalho turbulentas viagem em trem. Como são suaves e a unidade base é suficientemente pesada, é possível abrir e fechar o portátil com uma mão. O ângulo máximo de apertura de um pouco mais de 100 graus não causa restrição alguma. Adicionalmente ao design de concha, o gancho ramshorn contribui para o transporte seguro. Ele mantém o equipamento seguramente fechado e pode ser aberto facilmente com o botão deslizante na frente. Vamos começar com um tour ao redor do próprio equipamento. Notamos que o posicionamento favorece um pouco aos usuários destros. Dependendo da utilização de entradas individuais, alguns cabos podem encher o lado esquerdo, o qual poderia obstruir consideravelmente a área de trabalho à esquerda do portátil. Duas das cinco entradas USB o entrada para tela, a VGA e a RJ45 estão na área central esquerda. Em oposição, a Lenovo tomou cuidado no posicionamento de entradas que potencialmente estarão ocupadas de forma permanente, como as outras duas entradas USB e a entrada combinada eSATA/USB, na área posterior direita. Adicionalmente, a direita aloja, da frente para trás, um conector de áudio combinado de 3,5mm, o drive ótico em um compartimento Ultra Bay, um leitor de cartões 4em1 que suporta SD, MM, SDHC, SDXC, e uma entrada ExpressCard34 port. A parte posterior é completada por uma entrada USB energizada e um modem RJ11. O adaptador de força também é conectado na parte posterior do case. Infelizmente, a Lenovo, como a Dell no seu E6420, esqueceu-se de instalar uma entrada USB no curso de atualização. Embora a interface eSATA também ofereça um índice de transferência de dados mais alto que o de um USB cada vez mais memórias de armazenamento mássico estão sendo oferecidas com entradas USB e o eSATA esta desaparecendo pouco a pouco do mercado. Em comparação com a concorrência, também notamos que a Dell recorre à utilização de uma entrada HDMI no E6420 e por isso aceita as restrições pertinentes. Em oposição, a Lenovo permanece decidida na instalação de uma entrada para tela diretamente no equipamento. Comparado com o seu predecessor, o T410, quase nada significante foi modificado. Apenas uma interface USB energizada foi adicionada. Além disso, a disposição das interfaces foi corrigida, mas não realmente melhorada. Portanto, se você encontrar cabos na área de trabalho do lado do portátil, ou se você não deseja voltar a conectar todos os cabos após o uso móvel, você pode fazer uso de uma estação docking. A entrada docking está, como é habitual, na parte inferior do portátil. Por falar em estações docking – continua sendo interessante ver quais soluções docking conseguirão chegar a te a Europa. Atualmente, dois modelo estão disponíveis para oT420 nos EUA O ThinkPad Mini Dock Plus Series 3 US/Canada/LA -> infromação do fabricante por cerca de 250 Dólares Americanos. Ele permite conectar três monitores externos adicionais adicionalmente à tela instalada. Em segundo lugar, a entrada ThinkPad Port Replicator Series 3 -> informação do fabricante por cerca de 280 Frontal Botão deslizante para abrir Lado Esquedo Ventilador, VGA, RJ45 LAN, dois USB compartimento para disco rígido Lado Posterior RJ11, USB energizado, bateria, conector de força, ventilador Lado Direito conector de áudio combinado, drive ótico, ExpressCard34, Leitor de Cartões 4em1, USB entrada combinada USB/eSATA, compartimento de segurança KensingtonComunicação Como o T410, o nosso T420 de teste ganha pontos uma extensa configuração de comunicação. Tudo o que é útil e está disponível está instalado. Um módulo Bluetooth versão é opcional, e está instalado no nosso equipamento de teste. Este permite a troca de dados com equipamentos pequenos portáveis, como PDAs ou telefones celulares. Também opcional é um módulo de banda larga móvel F5521gw Mobile Broadband também instalado em nosso Thinkpad. O compartimento SIM equivalente está localizado no compartimento da bateria. Os cabos da antena estão instalados para que assim um módulo UMTS/HSPA possa ser instalado depois. Com respeito ao WLAN, são dadas várias opções. Um módulo Centrino Ultimate-N 6300 AGN agn da Intel está no equipamento de teste. O portátil pode ser conectado às redes Ethernet através da conexão de rede Intel 82579 LM Gigabyte. As videoconferências não são um problema com a câmera opcional de 720p HD es esta configuração. Segurança Adicionalmente ao obrigatório Seguro Kensington Lock, o T420 também tem um leitor de impressões digitais, entre outras coisas. Um teclado a prova de derrames evita a perda de dados no caso de um acidente com líquidos. Suprimentos Além da parafernália necessária, como o adaptador de força e bateria, apenas um pouco de informação impressa está incluída no conteúdo da entrega. O usuário deve criar DVDs de recuperação para o pré-instalado Windows Professional 64bit imediatamente depois da compra. Porém, isto não é um problema com a conveniente ferramenta ThinkVantage. Garantia A garantia padrão para a gama T é de três anos na Europa. A garantia básica inclui apenas um ano de serviço “bring-in” nos EUA. Várias extensões da garantia podem ser adquiridas Nem o design nem a disposição foram modificadas em comparação com o T410. Aparte das teclas STRG e FN trocadas, estamos lidando com uma disposição padrão com agrupações de teclas claramente posicionadas. A tecla blue ThinkVantage mais uma vez é a tecla adicional mais chamativa. Ela abre as ferramentas ThinkVantage, respectivamente um processo de recuperação pode ser iniciado durante o booting. À esquerda dela está um botão de mute para os alto falantes e microfone e um controle giratório para o volume. A iluminação do teclado está integrada no marco superior da tela, como estava no T410. Esta pode ser ligada /desligada com as teclas FN+PGUP. A luz pode ajudá-lo a encontras o seu caminho nos dispositivos de entrada na escuridão, mas em nossa opinião não se compara com teclado com iluminação posterior. Os digitadores produtivos irão achar o teclado do Thinkpad muito agradável devido a suas qualidades mecânicas, deslocamento bem dosado da tecla e claro ponto de pressão. Adicionalmente, as teclas côncavas aumentam o conforto da digitação. Infelizmente, o teclado torna-se muito barulhento especialmente durante a digitação enérgica. No entanto, a digitação não é um problema desde o início. Touchpad e Trackpoint As semelhanças com o T410 são impressionantes aqui. O touchpad e trackpoint podem ser independentemente desabilitados e habilitados através do F8+FN. O touchpad comprova ter uma agradável superfície áspera com boas propriedades de deslizamento. O controle do cursor do mouse novamente é preciso sem problemas e os recursos multi-touch respondem conforme o esperado. Além disso, o rolamento através dos campos de rolamento na borda do touchpad também é possível. As bordas do touchpad dificilmente podem ser distinguidas do case que o rodeia devido a uma junta simples. Os botões correspondentes precisam de um pouco de tempo de adaptação, pois estão na borda angular. Eles são lisos, respondem bem sobre toda sua superfície e o clique não é muito barulhento. Alternativamente, também há um trackpoint vermelho. Ele permite uma navegação precisa do cursor do mouse. Os botões correspondentes são suficientemente silenciosos. Também não há reclamos com respeito à lugar do formato 1610 como é no T410, agora é usado um formato 169. A diagonal da tela foi marginalmente reduzida de 14,1 para 14 polegadas. Em compensação, a resolução foi aumentada de 1440x900 pixels para 1600x900 pixels. Com isso, agora há tantos pixels na altura total como no modelo anterior. No entanto, O dispositivo de teste ganhou um pouco de largura. Como é de se esperar de um equipamento empresarial, a superfície da tela foi revestida com um filme anti-reflexos. Com isso o equipamento não apenas atende os requerimento de telas de estações de trabalho, mas também é mais adequado para o trabalho em T420 tem melhorado no geral em comparação com o T410 em termos de avaliações. É mais brilhante e iluminado mais uniformemente. Apenas o valor de escuridão é levemente mais baixo que o do modelo anterior. Apesar de tudo, o melhor brilho resulta em um contraste um pouco mais alto. Em contraste, o E6420 pontua com um brilho máximo significantemente mais alto de 320 cd/m2 e ainda 277,7 cd/m2 em média. Em compensação, o portátil da Dell deve admitir a clara derrota no campo do valor de escuridão e contraste. 197cd/m²190cd/m²214cd/m²213cd/m²223cd/m²221cd/m²210cd/m²198cd/m²194cd/m² Distribuição do brilhoLEN40A1Gossen Mavo-MonitorMáximo 223 cd/m² Nits Médio cd/m²iluminação 85 %Contraste 1621 Preto cd/m² AdobeRGB 1998 Argyll 3D61% sRGB Argyll 3D Display P3 Argyll 3DComo pode ver nas fotos de comparação, que foram feitas com vários perfis de cores ICC, o T420 não foi feito para a edição profissional de imagens. O Adobe RGB e sRGB não são cobertos. Por isso está na mesma liga do Dell E6420 com o mesmo tamanho da tela e resolução. As diferenças em vista da reprodução de cores se tornaram visíveis em comparação com telas com qualidade especialmente alta. Elas podem ser encontradas, por exemplo, no Apple MacBook Pro 13 ou no Dell XPS 15. Inclusive o irmão mais velho do T420, o T520, ganha mais pontos aqui. Com uma superfície anti-refletiva e um brilho médio de mais de 200 cd/m2, que também está disponível no modo de bateria, o modelo de teste é muito adequado para o uso em exteriores. O conteúdo da tela permanece suficientemente legível inclusive sob a luz direta do ultimo ponto que vimos para avaliar a tela é a sua estabilidade dos ângulos de visão. Resulta satisfatório horizontalmente e a imagem pode ser reconhecida se problemas inclusive em ângulos muito estreitos. Como é habitual na maioria dos portáteis, os ângulos de visão no plano vertical são consideravelmente menores no T420. Conseqüentemente, você pode ter certeza que precisará ajustar o ângulo de visão freqüentemente para garantir uma imagem legível, especialmente durante o uso em exteriores. Quando muita gente esteja olhando para a tela ao mesmo tempo, seus olhos devem estar quase na mesma de Visão Lenovo Thinkpad T420 4236-NGGA série Thinkpad T420 de portáteis baseiam-se no chipset QM57 Express. Atualmente vários modelos com Core i5 ou i7 da segunda geração estão sendo oferecidos. Para ser exato, o nosso modelo de teste foi equipado com um CPU Intel Core i7 2620M Sandy Bridge. Atualmente é o processador dual core mais veloz da família Sandy Bridge que foi introduzido no início de 2011. Pode processar até quatro threads ao mesmo tempo graças ao Hyper Threading. A tecnologia Turbo Boost permite que os de um núcleo possam acelerar dinamicamente de 2,7 GHz até 3,4 GHz, dependendo da carga e capacidade de esfriamento. Em comparação com os processadores Arrandale, a função turbo foi melhorada entre outras do Sistema Lenovo Thinkpad T420 4236-NGG O chip Intel HD Graphics 3000 com suporte para DirectX 10 incorporado diretamente no processador está disponível para a saída de vídeo no nosso equipamento de teste. Por isso, o desempenho gráfico está quase no mesmo nível de uma placa Nvidia Geforce 310M de gama baixa. Como o Latitude E6420, modelos com uma NVIDIA NVS 4200M e Tecnologia Optimus estão listados nos EUA. Nosso T420 tem uma RAM de quatro gigabytes DDR3 disponíveis para a memória principal. Eles estão em um só chip, inacessível para o usuário. Apenas o segundo, ainda desocupado compartimento é acessível através da coberta de manutenção. O usuário pode fazer uma atualização facilmente. Devido ao sistema operacional Windows 7 Professional de 64bit, os quatro gigabytes da memória principal podem ser aproveitados eficientemente, ao contrário de uma versão de 32 bit, e não há nada que impeça uma atualização da RAM. O controlador de memória do processador pode controlar um máximo de até oito gigabytes de RAM DDR3-1066/ de Experiência Windows 7ProcessadorCálculos por RAMOperações de memória por da Área de Trabalho para Windows de jogosGráficos 3D empresariais e de rígido principalVelocidade de transferência de dados de R10 Rendering Single CPUs 64Bit5438 Points Cinebench R10 Rendering Multiple CPUs 64Bit11507 Points Cinebench R10 Shading 64Bit5566 Points Ajuda PCMark Vantage Result 7845 pontosAjuda Tanto o processamento como o desempenho de aplicativos é previsivelmente um pouco mais alto que o do E6420 equipado com um Core i3-2310M. Os índices de desempenho estão de acordo com as expectativas nesta configuração de hardware. O nosso candidato de teste atingiu uma pontuação total de 7845 pontos, o qual deve-se especialmente à sua alta sub-pontuação de comunicações, no teste PCMark Vantage para avaliar o desempenho geral. Por isso, esta inclusive no mesmo nível de máquinas para jogos mais potentes, como oAsus G73SW GeForce GTX 460M, Intel Core i7 2630QM, em termos de desempenho de do Desempenho Gráfico O equipamento de teste ainda pode se enfrentar com máquinas para jogos como o Asus G73SW em termos de desempenho de aplicativos. No entanto, em vista do hardware gráfico, não tem chance alguma no desempenho 3D como esperávamos desde o início. Isso é confirmado pelos resultados no Teste Cinebench Shading e os vários benchmarks 3DMark. Infelizmente, os resultados do teste estão por embaixo de aqueles que seriam os esperados para uma HD Graphics 3000. No entanto, como as medições de energia sempre se mantêm por abaixo do par, temos que lidar com um equipamento defeituoso. Outro indicativo disto é que a detecção de dispositivos da Ferramenta ThinkVantage falha regularmente. Para excluir um problema nas configurações verificamos o BIOS e as configurações de energia no Windows 7. Vamos tentar conseguir um equipamento de substituição para uma análise de atualização. Vamos consultar os nossos testes detalhados do chip Intel HD Graphics 3000 e da folha de especificações da HD Graphics 3000 para mais informação. 3DMark 05 Standard 6131 pontos3DMark 06 Standard Score 3381 pontos3DMark Vantage P Result 1696 pontosAjuda Velocidade de Transferência Mínima MB/s Velocidade de Transferência Máxima 102 MB/s Velocidade de Transferência Média MB/s Índice de Explosão MB/s O disco rígido do nosso equipamento de teste é um ST9500420AS da Seagate. Ele tem uma capacidade bruta de 500 GBs, onde uma parte é usada como uma partição de recuperação oculta. Ele alcança resultados coerentes nos testes HDTune e CrystalDiskMark com uma velocidade de revoluções de 7200 rpm. Um gravador de DVD também está disponível como outro equipamento de armazenamento massivo. Para ser precisos, é um Optiarc DVD RW do Sistema O T420 sempre permanece suficientemente silencioso sem importar a carga. O ruído do sistema e de constantes 32,2 dBA com carga leve. O disco rígido é um pouco mais barulhento com 32,5 dBA durante o acesso. O portátil de teste atinge apenas um nível de ruído máximo de 35,2 dBA durante o nosso teste de estresse GPU e CPU com carga total. Por isso o ruído operacional sempre mantém um nível aceitável. No entanto, as avaliações do consumo de energia 28W máx. indicam que o processador não aproveita sua máxima capacidade possível mesmo durante o teste de estresse. Monitorando a freqüência do processador com a ferramenta CPUZ registramos a freqüência predefinida de 2,7 GHz para o CPU no teste de estresse. Isto significa que não há overclocking em nenhum dos núcleos e no GPU durante a carga. O CPU funciona com uma freqüência de 3,19 GHz quando apenas o Prime95 está ativado. Quando o Furmark é adicionado, o sistema reduz para 2,7 GHz. Também conseguimos registrar um máximo de 3,19 GHz no Cinebench R10 Single Core rendering. O medidor de freqüência permanece no mesmo nível no multi core rendering. Conseqüentemente a freqüência máxima possível do i7-2620M de 3,4 GHz não é aproveitada em nenhum estado testado. Apesar de tudo, os resultados de benchmark que são determinados no Cinebench R10 se mantêm dentro da faixa esperada dos CPUs i7-2620M e não demonstram irregularidades com respeito a possíveis afogamentos.

Devemos apontar que o T420 na configuração que temos em mãos, não foi criado para aplicativos de gráficos pesados senão para office e internet. ° ° °C ° ° °C ° ° °C Máximo °CMédio °C ° ° ° ° ° ° ° ° °C Máximo °CMédio °C alimentação elétrica °C Temperatura do quarto °C Raytek Raynger ST± The average temperature for the upper side under maximal load is °C / 90 F, compared to the average of °C / 85 F for the devices in the class Office.+ The maximum temperature on the upper side is °C / 96 F, compared to the average of °C / 94 F, ranging from to °C for the class Office.+ The bottom heats up to a maximum of °C / 103 F, compared to the average of °C / 98 F+ In idle usage, the average temperature for the upper side is °C / 80 F, compared to the device average of °C / 85 F.+ The palmrests and touchpad are cooler than skin temperature with a maximum of °C / F and are therefore cool to the touch. - The average temperature of the palmrest area of similar devices was °C / 82 F °C / F. Alto falantes A qualidade dos alto falantes não pretende ser valorada como alta em um portátil de escritório para uso profissional como em, por exemplo, um portátil multimídia notebook. De fato, ambos os alto falantes estéreo, à esquerda e direita do teclado, são basicamente adequados para a voz. Não é possível desfrutar da música devido ao com diminuto, pobre em baixos e pesado nos agudos. Fones de alta qualidade, conectados ao conector combinado de áudio de 3,5 mm, podem remediar isto. O sinal é transmitido claramente, sem distorções e sem estática no teste apenas teste de áudio, sem medições.O nosso modelo de teste está no começo com uma bateria de lítio íon de 6 células de 57 Wh neste teste. Uma possibilidade de estender a duração da bateria é fazer o pedido da bateria de 9 células. A outra é o acoplamento de uma bateria de 9 células. De acordo com as especificações do fabricante, é possível uma duração máxima total da bateria de até 30 horas. Em qualquer caso, uma máxima duração de bateria de "apenas" sete horas e meia é possível com a matéria que temos em mãos. O teste BatteryEater's Reader determinou esta duração com brilho mínimo, com o módulo wireless desabilitado e em modo de economia de energia. Este índice é pouco realista para o uso prático devido ao mínimo é inútil brilho mínimo. Nós executamos o teste WLAN som um brilho utilizável, ou seja, desde o nível 12 a 15. Podemos fazer pesquisas na internet para até seis horas, também em perfis de economia de energia, neste cenário de baixa carga sem vídeos flash. A reprodução de um filme acaba depois de um pouco mais de três horas no teste de DVD. Foi executado com brilho máximo e módulos wireless desabilitados, bem como em modo "Vídeo". A duração da bateria cai em picada com aplicativos intensos 3D, brilho máximo, módulos wireless habilitados e modo de desempenho máximo. O teste BatteryEater Classic simula um cálculo OpenGL e registra uma mínima duração de bateria de apenas cerca de uma de Execução da Bateria Ocioso sem WLAN, min brilho 7h 28min Navegar com WLAN 5h 59min Carga máximo brilho 1h 06min O Latitude E6420 claramente tem a liderança nos testes de bateria devido a sua maior bateria de 9 células. As durações de bateria do nosso equipamento são, apesar de tudo, extraordinárias em relação com a capacidade da bateria. Isso se deve especialmente devido ao baixo consumo de energia. É um pouco mais baixo que o do E6420 com 6,8 para 11,5 watts no modo inativo. Surpreendentemente, o máximo consumo de energia não foi tão alto quanto esperávamos no teste de estresse 100% de carga do CPU e GPU. Somente o CPU comprova ter uma perda máxima de energia de 35 watts. No entanto, nossos medidores apenas registraram 28,6 watts para o sistema inteiro. Por isso, verificamos as configurações no PowerManagement da Lenovo em Windows 7 e as configurações do BIOS. Mas não encontramos nada em lugar algum. As configurações para o funcionamento conectado na tomada estão estabelecidas claramente em "Desempenho Máximo" no BIOS. O T420 também está disponível com uma placa de vídeo NVIDIA NVS 4200M dedicada nos EUA. Por isso a Tecnologia Optimus é usada para manter baixo o consumo de energia durante a carga baixa. Como o nosso equipamento de teste E6420 está equipado com a placa de vídeo NVIDIA NVS 4200M e opção Optimus, nosso T420 tem uma evidente vantagem no consumo de energia durante cenários de Thinkpad T420Além do aumento do desempenho esperado devido à nova geração de processadores, muitas coisas experimentadas e testadas foram mantidas. Isto também aplica-se tanto para o case como para as convenientes ferramentas pré-instaladas ThinkVantage. Pequenas modificações e upgrades podem ser encontrados na conectividade. Apesar de tudo, o usuário ainda tem que viver sem o USB Em compensação, uma entrada eSATA/USB foi instalada. A configuração de comunicações do portátil de teste é extensa. Todas as opções disponíveis são aproveitadas módulo de banda larga, Bluetooth versão WLAN com suporte para padrão n e gigabit Ethernet. Gostamos da tela de 14 polegadas que é marginalmente menor que a do T410 diagonal da tela. A disposição do desktop foi mantida, respectivamente inclusive foi melhorada em largura devido a uma resolução de 1600x900. Não há nada que impeça o uso móvel com a tela mate e o bom brilho. No entanto, o T420 apenas oferece valores padrão em termos de reprodução de cores. De acordo com o fabricante, supostamente é possível atingir uma duração de bateria de até 30 horas com a bateria de 9 células do sistema e adicionalmente, com a bateria acoplada de 9 células. Atingimos uma duração de bateria plausível de até 6 horas com nossa bateria de 6 células com uma capacidade de 57 Wh Teste WLAN. O T420 basicamente foi criado para clientes empresários que procuram por um sólido portátil de escritório com um bom desempenho de aplicativos e, apesar de tudo, boas qualidades móveis. Um leve aumento do desempenho em aplicativos 3D pode ser esperado nas configurações com uma placa de vídeo Nvidia NVS 4200M dedicada, que também suporta DirectX 11, listados nos EUA. No entanto, o nosso portátil de teste não sofrerá uma mutação para uma estação de trabalho co gráficos mais potentes mesmo com esta solução gráfica. Por cortesia da...
