while watching video and when not plugged in, the screen shuts out black but sounds of the movie is still running smoothly but no visual...seems cpu still running but screen display is out of control. Sometimes when not plugged and using MS word or things like that, it again shuts out screen, so i use function keys on keyboard and it sleeps, then i press power button again to turn on the device....whats the problem?...

You haven't given us any specs on your computer, so it would hard to figure out. I can think of several things, but with out knowing about your computer and it's graphics, it would be just shots in the dark.
