Monitor screen goes dark

[MGraham1]

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?

go to control panel and make sure screensaver and hibernate mode is off.

You can try to update your drivers
THere are 2 main ways to do it
Go to the windows update at microsoft.com
Or you can go to start->right click on my computer->properties->hardware tab->device manager-> find your graphics card---> rigth click and select update drivers
If this does not work try to reinstall the original display driver
