I have a windows 7 laptop that the screen went blank on but it worked on an external monitor. I opened it up and unplugged and replugged in the video cable and booted it again. The screen worked! yay! So I rebooted a few times without logging into the computer and the screen continued to work. 

 

After the 3rd reboot I logged into the computer let it load up and then rebooted the computer. The screen went blank...won't display again except on an external monitor. I'm quite certain, though I haven't done it yet, that if I were to open the computer up and re seat the video cable again it would work until the next time I restarted after logging in.

 

I've never seen a computer do this before...and it's driving me up a wall...tried to press the keys to switch between computer/monitor and extended display but that didn't change anything -_-

 

HELP!!!

 

 

Edit:

 

I was told by one of our helpdesk employees that when she plugged it into her external monitor it was on system restore and she did the system restore and it came up...but after logging in and rebooting it went blank again. She then brought it to me and I did the above.

This sounds like a hardware problem to me.

And, I can't run any tests - as the results won't display

I'd suggest posting over in the Internal Hardware forums:    http://www.bleepingcomputer.com/forums/f/7/internal-hardware/ 


My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.
