I was recently on my Laptop notebook "Hp Compaq NC6400" and the screen went black on me but the computer was still runnning. I tried shutting the comuter down and restarting it. Didn't work. I tried connecting the notebook to another monitor it worked for a few minutes until the my notebook screen blacked out again. I tried unplugging the notebook and pushing the power button to get the current out and that only worked for a few minutes before blacking out again. Someone please help! You assistance and help is very much appreciated!!!!!!
