I awoke today to find my powerbook "On" the fans were not running but the case was very hot and the caps lock key lit up when pressed, something that happens only when the computer is on. So, I try to shut the computer down by pressing the power button.It doesn't work so I remove the battery and let the computer cool down. After, I starp up the computer, it starts and I can hear the HD begining as well.The keyboard lights up as well. THE PROBLEM The display doesn't work, not even when connected to an external power supply. Also, I think the fans aren't coming on for some reason. So, effectively I have been able to close/start the computer but there seems to be no video coming out of it.
