Build – Design – Hardware

In terms of design, when compared to Thinkpad T410, this model does not have any significant change. However, a good 16:9 display has been incorporated which is an add-on to the previous model. T420 makes use of Intel Core i5 processor, which works at 2.6 Ghz and also supports the hyper–threading feature. 4GB of DDR3 RAM, Hitachi Travelstar hard drive have been accommodated in this machine. The screen resolution has been improved when compared to the previous models. Intel Turbo Boost Technology 2.0 has been used which increases the processing speed.

Keyboard – Mouse – Webcam

There is barely any change in terms of layout and design aspects related to the keyboard, touchpad and the left and right clicks. But the finger print scanner has been re-positioned and placed on the right side. The in-built microphone boasts of noise-cancellation feature which is useful for those who use online audio and video conferencing facilities. A 720p HD Webcam is great for video calls.

Intel LAN and WLAN cards are included in this machine. Apart from that, there are three USB 2.0 ports and regular microphone in and audio out jacks. In terms of I/O ports T420 isn’t at pace with its competitors in this segment. The 9 cell battery life promises to provide backup for atleast 15 hours, which is a great plus point for Lenovo fans.
