Its a reasonably cool and quiet business laptop and you can use it on your lap for a prolonged period of time without feeling too much warmth. However, you'll have to make sure that the vent on the left side doesn't get blocked. The fan near the vent spun consistently even while typing this review, but it didn't get annoyingly loud.

Single Review, online available, Very Short, Date 09/21/2011Lenovo ThinkPad T420 ReviewSource Student Buying Guide versionThe ThinkPad T420 or T420i is a great option as a college laptop. 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. Overall a thumbs up on buying the T420 that is a worth successor to the previous ThinkPad T410 and improves on an already great line of laptops.

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.

Find out more about how we test. Lenovo's ThinkPad T series notebooks have long been the gold standard for mainstream business systems because of their strong performance, superior build quality, and best-in-class keyboards. With the 14-inch ThinkPad T420, Lenovo has made a couple of changes, switching the screen to the now-standard 169 aspect ratio and giving it the latest Intel 2nd Generation Core series CPU. Is the T420, $1,179 as configured, the business notebook to beat?Update Read our review of the ThinkPad T460, the latest version of this computer. DesignThe ThinkPad T420 follows the classic ThinkPad aesthetic business users have come to know and love over the years. The matte black, rubberized lid with its simple silver logo and raven black sides, bottom, and interior are all long-time ThinkPad staples, as is the tiny red TrackPoint pointing stick that sits between the G and H keys. Like previous ThinkPad T Series notebooks, the T420 is designed for durability. The rubberized ABS plastic lid, carbon-reinforced bottom, and internal roll cage help protect against shocks and x 10 x 1 inches and pounds with the high-capacity nine-cell battery, the ThinkPad T420 is a bit larger and heavier than the Toshiba Tecra R840 x x inches, pounds, but it's still lighter than the HP Elitebook 8460p 13 x x inches, pounds and the Dell Latitude E6420 x x inches, pounds with its extended battery. Using the standard six-cell battery cuts the T420's length to 9 inches and its weight to pounds. Lenovo's ThinkPad T420s, designed as a lighter alternative, weighs only 4 pounds and measures only x x inches.[Which ThinkPad is Right for You?]Keyboard, Pointing Stick, TouchPadThe classic, spill-resistant keyboard on the ThinkPad T420 features 7 rows with a full range of keys, even rarely used ones such as scroll lock and pause. Enlarged Esc and Delete keys make it easy to perform these frequent functions. The combination of strong tactile feedback and a smile-shaped key surface allowed us to achieve an 86 word-per-minute score with a 1-percent error rate on the Ten Thumbs Typing Tutor test, well above our 80 wpm average. However, the typing experience on the 13-inch ThinkPad X1 remains the industry's best because of that notebook's soft-touch palm rest and even more responsive other ThinkPads, the T420 has both a TrackPoint pointing stick and a touchpad. We're huge fans of the TrackPoint because it provides the most accurate way to navigate around the desktop short of using a mouse, and it allows you to move the pointer without lifting your fingers off of the home row. If you don't like pointing sticks, the 3 x textured touchpad provides accurate navigation around the desktop, and its two discrete mouse buttons provide just the right amount of feedback. However, multitouch gestures such as pinch-to-zoom are not smooth at ThinkPad T420 stayed pleasantly cool throughout our testing. After streaming video for 15 minutes, the touchpad measured a frigid 82 degrees, the keyboard an icy 81 degrees, and the bottom a cool 87 degrees Fahrenheit. We consider temperatures below 95 degrees and AudioThe 230-nit, matte display provided sharp images and plenty of desktop real estate thanks to its optional 1600 x 900 panel. When we watched a 1080p QuickTime trailer for the movie Point Blank, images were sharp and motion smooth with viewing angles solid up to 45 degrees to the left or right. However, when we streamed a 720p Flash episode of Fringe from the edges of objects seemed a little pixelated, perhaps because the screen had a higher resolution than the video. We highly recommend the 1600 x 900 panel, a $50 option, because it shows a lot more of your favorite web pages and documents without forcing you to not as high fidelity as audio-focused consumer notebooks such as the Dell XPS and the HP Envy series, the Lenovo ThinkPad T420 provides surprisingly good music playback. Whether we were playing Kool and the Gang's jazz-oriented "Summer Madness," the bass-heavy "Between the Sheets" by the Isley Brothers, or Motley Crue's guitar-laden "Looks that Kill," sound was accurate and loud enough to fill a medium-sized room. We could even make out a solid separation of sound between the speakers, which sit on either side of the and WebcamThe ThinkPad T420 has plenty of connectivity options, but it's missing a couple of the obvious ones. On the right side are an Express Card 34 slot, a 4-in-1 memory card reader, a USB port, and a USB/eSATA port. On the back are a FireWire port and a powered USB port that allows you to charge devices with the system off. The left side houses VGA, DisplayPort, Ethernet, and one more USB port for a total of four. Conspicuously absent are USB ports and HDMI-out, neither of which are even available as options. Considering that we've been seeing notebooks with USB for over a year now and that Lenovo offers USB on many other ThinkPads the X1 and W520, for example, this is a pretty glaring 720p webcam provided sharp images even in low-light situations. In our dark living room, fine details of our face were visible when we snapped a picture at 1280 x 720 and chatted on Skype in standard def. However, like with many other webcams, our face appeared shadowy if there was a bright light source directly behind; this occurred when we tried snapping a photo while sitting in front of a window with sunlight coming conferencing software features a unique keyboard noise suppression feature that, on our tests, completely muted the sound of our typing as we chatted on Skype. The software also allows you to configure the dual-array microphones for a single voice or group its Core i5 CPU, 4GB of RAM, an Nvidia NVS 4200M graphics chip, and 7,200-rpm hard drive, the ThinkPad T420 was strong enough for anything we threw at it, from playing 1080p video to spreadsheet crunching and light gaming. On PCMarkVantage, which measures overall performance, the T420 scored a strong 8,197, much higher than the 5,596 thin-and-light notebook category average, the 7,728 turned in by the Toshiba Tecra R840, and the HP EliteBook 8460p both have the same Core i5-2520M CPU.The 500GB, 7,200-rpm hard drive booted into Windows 7 Professional in a speedy 48 seconds, much faster than the 65-second category average. The drive took a modest 3 minutes and 5 seconds to complete the LAPTOP File Transfer test, which involves copying of mixed-media files. That's a rate of MBps, a little higher than the 26 MBps category average but well behind the MBps provided by the Dell Latitude E6420 and its 7,200-rpm Oxelon Media Encoder, the T420 transcoded a 114MB MPEG4 to AVI in 43 seconds, 15 seconds less than the thin-and-light average, and on a par with the Toshiba R840 41 seconds and the HP 8460p 42 seconds.GraphicsOur ThinkPad T420 review unit came with Nvidia NVS 4200M and Intel HD 3000 GPUs and Nvidia's Optimus graphics switching technology to toggle between the two for the best combination of battery life and performance. On 3DMark06, which measures overall graphics prowess, the ThinkPad T420 scored a strong 5,583, well above the 4,006 category average, the 5,060 provided by the Dell Latitude E6420 with its Intel HD 3000 integrated graphics, and the 5,032 scored by the HP EliteBook 8460p with its AMD Radeon HD 6470M ThinkPad T420 isn't a gaming system, but its discrete graphics chip is good enough to get decent frame rates on some popular titles. At autodetect settings, the T420 provided a solid 61 frames per second when playing World of Warcraft, a little less than the 86 fps category average, but much higher than the 41 fps that the Dell Latitude E6420 got and the 52 fps scored by the HP EliteBook 8460p, and impressive given that most notebooks in the category have lower resolution screens. With special effects turned up, the rate dropped to a still-solid 32 the more demanding Far Cry 2, the ThinkPad T420 got a solid 37 fps at 1024 x 768 resolution, on a par with the fps category average. When we upped the resolution to 1600 x 900, that rate dropped to a modest 25 fps, which is comfortably above the 20 fps category LifeWith its nine-cell extended battery, the ThinkPad T420 lasts all day and then some. On the LAPTOP Battery Test, which involves continuous surfing over Wi-Fi, the notebook lasted a whopping 10 hours and 36 minutes, more than double the 515 category average and the battery life of the T420s 5 hours. That time is also significantly longer than the HP EliteBook 8460p 601 and the Toshiba Tecra R840 634. Only the Dell Latitude E6420 with its extended battery came close, lasting 8 OptionsThough our review unit carries an MSRP of $1,179, the ThinkPad T420 starts at just $789. For that price, you get a Core i3 CPU, integrated graphics, a 1366 x 768 display, but the same 500GB hard drive and 4GB of RAM as our review unit. If you want discrete graphics, you'll need to buy the $1,089 model that comes with a Core i5 CPU and 1600 x 900 screen, along with its Nvidia NVS 4200 GPU. Configuration options include a choice of storage 320/500GB hard drive or 128/160GB SSD, up to 8GB of RAM, a choice of Core i3, i5, or i7, and several different Wi-Fi cards. Strangely, the webcam and fingerprint reader are not standard, costing $20 and $30 matter what other options you choose, both the 1600 x 900 screen $50 and the nine-cell battery $50 are absolute musts for maximizing your productivity and Fingerprint Reader, and WarrantyLenovo bundles the ThinkPad T420 with the standard set of ThinkVantage utilities. Among these are the ThinkVantage Power manger, which allows you to exert fine control over the system's power profile. We particularly like the Instant Resume feature, which keeps the Wi-Fi card active for 10 or more minutes after you put the notebook to sleep so you don't have to wait for the system to reconnect after you wake utilities include Access Connections from managing your wireless connections, Password Manager, and Rescue and Recovery for Backups. The T420 also comes with Corel DVD Movie Factory for burning ThinkPad T420 comes with a powered fingerprint reader that can read your fingers even when the system is off.

From 2004, the company has been the largest laptop manufacturer in China and got the fourth largest manufacturer worldwide after the acquisition of IBM's PC division in 2005. 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. In the smartphone market, Lenovo did not belong to the Top 5 global manufacturers in 2016.

Business class. The ThinkPad T420s is mainly to convince business customers of its advantages as a powerful and yet portable companion. Equipped with a Core i7-2640M and a fast SSD from Intel as well as built-in UMTS, Lenovo has created good prerequisites for this another notebook range in the business sector enjoys such a high reputation as the ThinkPad models from Lenovo. The greatest robustness, high performance hardware and long battery runtimes are the qualities that let the manufacturer of the T series especially stand the following, we will examine to what extent the ThinkPad 420s can keep these promises. 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...
