This forum has saved me in the past and I am hoping that it will help me again. I have a HP Pavilion DV2500 running windows vista. Recently it has been shutting off sporadically; I assumed it was overheating since it seemed very hot and I did not hear a fan running. Cleaned out all of the vents, removed the ram and cleaned its connections, and also removed the HDD and tried to reboot. Nada. The computer won't even come on at all. The lights along the the top scroll are on (power, dvd, volume, etc) and the front led light signally power is on. Also the light that shows that the track-pad is active is glowing blue like normal. But no noise from the HDD, fan, and no display. It would still turn on until I cleaned out the vents using duster spray.
Totally confused and concerned about my HDD contents.
