Not sure if anyone here can help with this. I have an IMB Thinkpad 600. I'm not very technically savvy, so I have no idea how to solve this problem. Lately, if I'm away from my computer for a bit, instead of going to screen saver, the screen will just go dark, and I cannot get it to light back up again. Moving the mouse, hitting any keys, do nothing. When I say it goes dark, I mean it goes black, as if its going to screen saver mode, but it will not come back on again. Sometimes I can get it to light back up by hitting F7, tho it's never been set for another display. Anyone have any suggestions or ideas why this may be happening?
