I have mentioned before that I press down (with my finger tips) on the screen cover that is removed in the picture of the last post before this one (I am referring to the one between the hot buttons and the hinge)and it works fine as long as I don't pick up or move the laptop. If I do that from left to right across the screen cover while the wi fi light is blinking and it stops right away. I haven't moved my laptop in 6 months and I haven't had the problem. I just have a laptop that you can't move. Dilbert lives!
