Unfortunately, the pressure display fail is a common problem of the series (according to my experience). This issue is probably connected with a flexi cable connector, whis is placed under the chassis in mentioned place next to the keyboard. I also strongly reccomend SSD hard drive to increase the experience.
Superfluous. Lenovo's 15.6-inch notebook only manages poor battery runtimes, despite a frugal CPU. It cannot really be called a bargain at around 400 Euros, either.
