The first order has shown equal during commissioning that the keyboard is defective. The laptop has consistently posted only zzzzzzzzzzzzzzzzzzz. The Z button was mechanically ok. But she was not to persuade them not to write zzzzzzzzzzzzzz. So defective and returned. The second laptop that I then ordered was clear evidence of use. When unpacking, smudges and fingerprints on the screen outside and inside and on the keyboard. The Lenovo Siegel was new on board. So it seems that returned laptops are re-packaged and sent to the next customer. An absolute impudence! I can not recommend to anyone, let the fingers of this notebook, only anger.
