I have an ongoing problem with my laptop as that quite often the screen will just go off.... the laptop isn't shutting down or anything just the screen goes off and won't come back on without a hard power rest. Then it comes back on fine. It often happens if you slightly knock the laptop, or just randomly sometimes. It's as if something is disconnecting. Not really sure what to do. Laptop does get warm but I'm pretty convinced it's not that or the whole laptop would shut down (as it has before).... it's like there is a connection that is very sensitive and turns the screen off at the lightest touch or knock. Any ideas anyone ?
