Problem with laptop screen randomly going black

Kealoha

This has happened twice in the past maybe four days or so, and never before that. Basically, I'll come back to my laptop after I've been gone for a while, log back in, and then start to do something and the screen will go black, almost like it's going back to sleep. However, nothing I press can get it to come back on, and the entire computer isn't shut down; I can still shut down the computer (I can hear the windows log off noise if I do the correct key patterns to shut down) so it's just a problem with the screen.

If it matters, the entire time I'm always plugged into an outlet; it's never running on its battery. My only amateur guess would be that something dealing with display is overheating, as the area I keep my laptop in isn't the best ventilated and thus doesn't receive much of the AC.

Anyone know what's up?

Usually when this happens, it's a loose connection somewhere. Try jiggling the display a bit to see if it comes back on. You can attempt to remove a few pieces and tighten up the connections (which usually get loose from repeated opening and closing of the lid.). Of course, don't do anything like that if it's still under warranty. If it's not, most manufacturers provide guides on laptop disassembly, so it's not terribly difficult.

Alright, great. Good to hear, even if just from one source, that it's nothing too serious.

Okay, well.. the problem has gotten worse. This morning it wouldn't stay on at all.

I opened it up and everything (warranty was already expired) but I didn't know what to do once I got there. So I put everything back together and it starts up fine and everything, but the problem persists.

Something that I noticed before even opening it up was that when it shuts down there is a high pitched buzzing noise just before. So, something is wrong.

Shit man, are you me? I mean seriously this is exactly what's happening to my laptop. Of course, mines still got warrenty and they're coming out to replace the screen tomorrow....

For me shutting the lid, waiting a second, then opening up would cause the screen to come back on. I got some flickering the next day then a corner went really hot and a burnt black color.

I wish I could be more helpful. They did suggest reseating the monitor cable but that didn't do anything.

I actually just found out that my laptop is still under warranty. For 3 more days.

Luckily I didn't disconnect anything or break/remove any stickers, so it's not void. Devout, who did you contact? I am chatting with customer service but they are absolutely no help.

The guy told me to reseat my harddrive. Seriously.

EDIT: Nevermind. I was just informed that a problematic LCD isn't covered by my warranty. So, uh, yeah.

EDIT: Jesus. A minute after I edited this the manager of the tech support place called me and said that the rep had given me incorrect information. So, I am sending it in.
