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. Using the bundled security software, we were able to enroll our index finger in just a couple of minutes.

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.

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.

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.
