Lenovo Thinkpad T420 has the second generation dual core Intel i5 2520M processor (3MB cache) at 2.5GHz speed with Intel Turbo Boost that moves the speed up to 3.2Hz as require by more demanding tasks and Hyper threading for decent four-way processing power, 8GB SO-DIMM DDR3 SDRAM at up to 1333MHz speed, 320GB Serial ATA HDD hard drive at faster 7200rpm rotating speed but not as fast as an SSD and 64-bit Win 7 Professional. 14 inch matte TFT HD display with 1366 x 768 pixel resolution offers decent picture quality.

Lenovo Thinkpad T420 weighs 4.5 pounds and measures 13.50 x 1.20 x 8.80 inches so it is average weight for its size and a little thicker than normal but feels very solid and robust. Ergonomic spill-resistant backlit keyboard with Thinklight keyboard light is very comfortable to type on- feels snappy but without the 10-key numeric pad on the side but many people prefer it without as it just gets in the way and has the UltraNav dual-pointing system with a TrackPoint with Internet scroll, Press-to-Select and magnifying glass and a wide and functional multitouch touchpad just below in the middle and a special Fn key in the lower left. There are mixed reviews on battery life of 6-cell battery varying from 3-4 hours to 8 hours.

Conclusion: Lenovo Thinkpad T420 ‘enterprise notebook’ is promoted as the ideal balance of manageability, security and portability, it works smoothly and is a very fast computer with intelligent features, has great build quality and product engineering for how much it costs. RAM is expandable as the i5 2520M supports up to 16GB and if you want more speed overall simply swap the hard drive with SSD or you may get an extra HDD/SSD slot by replacing the DVD drive with a HDD caddy. Keyboard is both backlit for working or playing comfortably with improved visibility in the dark and spill-resistant in case of liquid spillage accidents and those that have spilt their drinks into their keyboard know how helpful this feature is. It even has a Fingerprint Reader on the palm rest so none will be able to use your computer or have access to your data without your permission. Quarter 1 2011 release Sandy Bridge Intel i5-2520M has the Passmark benchmark score of 3559 as of today, which puts it in the high mid range CPU category which means it can handle more demanding tasks quite well and a Thermal Design Power- TDP of 35 watts. Despite all the power and performance chassis stays cool and the system works quietly. 720p webcam quality is pretty good for live work conferences. Optical DVD drive would come in handy for work but there is no HDMI (you may get an inexpensive displayPort to HDMI converter) and you’ll need to do with three USB 2.0 ports as the faster 3.0 is not installed.
