Oddly enough it seems that the track pad/mouse pointer stops working when the screen is black. e.g. during the time the screen is black the pointer on the screen doesn't move. I thought it might be related to the back light on the keyboard or the touch buttons.
If you are thinking of buying or currently own a Dell XPS 17 (L702x) good luck. I purchased my laptop in march 2012 and I personalized the purchase for high end performance. I have had nothing but trouble, pain and suffering, from this unit.
