Lately since i close my insipron for a long period of time ( like 1 hr) and open it back i can't see the screen.. its black. I keep on having to turn off my laptop and turn it back on.
This never use to be a problem, only till recent. Any ideas why? The power is in also if that matters
( btw i config so it does nothing when i close, been like this for months now)

thanks in advance!
