To my great regret, two stars. After 2 weeks of loyal, sudden failure. Boot failed! Apparently a hard drive problem. It can happen but it casts doubt on the general quality of the craft. Computer returned by Chronopost in Germany for repair through customer service Lenovo, friendly and efficient. Packaging + over-packaging requested by the customer service: a little complicated to set up. 15 days to wait now. It will be seen for stars to return.
