Screen stays blank after overnight sleep mode

Hi there,

For about 2 months I've been having this annoying problem, where my PC's screen is staying blank after resuming from sleep mode, although the computer is actually alive and okay (I can even use Teamviewer to see the screen)

The strange thing however is that it only happens after a longer period of time, so if I resume during the day, after one or two hours, the screen comes back fine, its only after a night when I resume the next day that it fails to start up the graphics.

Does anyone have any idea why this happens, and what could be the difference between sleeping for a few hours and a whole night??

Thanks for any input!

Marcel

  1. Thanks for you answer, I tried all kinds of combinations in the power settings, I havent noticed any influence on the problem though, it just makes the PC shut down stuff during the normal 'daytime use' but I don't think it has an influence on the sleep mode resume behavior unfortunately....
