The touchpad was not working. The mouse jumps uncontrollably around the screen. I learned now that this problem has been known about for hundreds of users in forums since 12/2012. Nevertheless, Lenovo has this not been fixed and resold defective goods.
The WLAN is exceptionally weak and is temporarily out suddenly, inexplicably. Here I compare it with an old Vaio notebook and my ipod.
Thus, the notebook went back immediately and also my future confidence in Lenovo.
