I bought a Gateway M-6750 notebook from BestBuy 6 months ago. I haven't had any issues until tonight. I tried to turn it on and it wouldn't power up. I know I fully charged it the night before and used it for about 15 minutes then I did a shutdown and went to bed. I then plugged up the charger and it powered up but nothing on the LCD. I tried pressing the "fn" + f8 key to see if I could brighten the screen but nothing happened. When I physically open and close the notebook, it looks like the LCD momentarily lights up then goes out again.

I unplugged the battery and tried to turn the notebook on using just the charger but it wouldn't power up.
The weirdest event is that after 15 minutes hooked up to the charger, the battery indicator turned from red (charging) to blue (fully charged). Still no light on the LCD but everything else is working. If I look hard enough I can see the Windows login screen but it's very faint.
I'm not sure this is still under warranty or not. Does anyone have any suggestions or ideas as to what happened? How can I fix this?
