I just got my x120e and I notice some very fine vertical lines running down the screen in a grid pattern. Is this normal? On my Macbook pro and desktop monitors I don't see anything like this.
No that is not normal. I believe that Lenovo corrected this either by a chipset or BIOS update. Over at the Notebook Review Lenovo forum they have quite an extensive X120e owners thread that deals with various issues and questions.
