Every so often if I move the laptop the screen will go black. When I hit the mousepad I get nothing. I tap the power button once I and if I turn the caps button on I do see the light on. I then hit the mouse pad a few times and I get nothing. Sometimes it comes on but then I have to reboot. Sometimes when I reboot I loose the cursor but I get it back after another reboot. Is there any simpler way of getting my screen back? I noticed it changed after a mouse upgrade but I have reverted back to the original mouse file and it worked for a bit. Any help would be appreciated.
