The machine was easy to set up, but had black streaks of pixels on the screen at all times. I tried to correct the problem by research and found no fixes. I contacted Lenovo Service and they accepted for repair. In due course, the repairs were made and the machine returned.I have had it back for about two weeks and now it won’t power up. The repair has been accepted, but I am not getting use of the machine again.Unfortunately, I am twelve days past my return date.
