Background
The ThinkPad T400s was noted for its sturdy and clean design, with traditional left and right mouse clickers on a trackpad. They also implemented a red trackpoint device which also works as a mouse. ThinkPads came with an Intel Core 2 Duo processor and 2GB of RAM standard and operated on the Windows Vista or XP platforms. The 400 series had a 14.1” widescreen with a fingerprint scanner for a more secure login.
Other leading technology for this laptop were the switchable graphics, allowing the use to switch between a discrete or integrated graphics card. These laptops were primarily praised for their long battery life, which was a result of the switchable graphics. However, in their 410, 420, and 510 models they announced a battery recall. Overall, the Lenovo ThinkPad T400s has competitive specs when compared with other business laptop models as shown here.
