A child was messing with my laptop keys for a split second, now the volume bar keeps popping up on its own and the volume slider keeps going up on its own to the max volume as well. Occasionally my WiFi will disable itself. And the screen keeps going from dim to bright on its own. Sometimes the mouse will lock up and I have to hold ctrl alt delete to move it again. I tried doing a system restore but that didn't fix it. I read in another forum some people saying the problem has something to do with static building up in the motherboard or something and all you have to do is unplug your laptop from the cord and remove the battery and turn it back on without the battery, however the battery on my laptop is non removable. I have a Samsung QX44 laptop and it is Windows 7. Please help
