The screen on my netbook (http://www.experts-exchange.com/M_5233204.html
) goes blank randomly.
- The computer will not be idle, I was actively working on something.
- The power light is on (the only LED on my unit) and I can hear the HD
- The screen is ON but black. Using the laptop function key to switch display (to external monitor like for a projector presentation) will cause the screen to flicker for a brief flash - I can make out faint gray horizontal lines - and then return to same black screen with the monitor on.
- The computer is unresponsive to the graphic card's hot keys (Ctrl + Alt + F1/F3 would toggle between Monitor and Notebook screens) - I've tried this both when it was and wasn't attached to an external monitor.

This happened again this morning.
Iwas plugged into my external monitor. I switched (Ctrl+Alt+F3) to the netbook display only and unplugged the monitor cable to continue my work elsewhere. After a few minutes the screen went black. Outlook was running. Firefox was running with a youtube video playing. The screen when black but the video was still playing! The keyboard hotkey mentioned above for the video card did not work. Since I knew the computer was still running, Alt+F4;Enter closed firefox and stopped the music. Win Key+D; Win Key; Alt+F4; U shut down the computer. This is great because in the past I didn't know windows was working fine when the screen when black.
There's just no video being sent to the netbook's display. Plugging the external monitor cable does help. The netbook screen remains on but black, while the external monitor's light remains orange not green (no video input).
Any ideas on how to prevent this from happening again? Any ideas how I can my computer (in the dark) how to switch to netbook display ONLY? Any ideas?
