It does kinda sound like the fan(s) attempt to spin but again, hard to tell when it powers on for about 2 seconds. When I try to power it on, I don't get display but not sure if I would see anything within the 2 seconds it 'powers on'. My friend said the laptop went to a blank screen but still sounded like it was running and left it. I did some searching online about this model and sounds like quite a few people are having this exact issue or issues very similar. I have cleaned all the fans so everything looks good. push the power button and it should turn on. put the battery back in and plug in the AC. I have also tried doing a Hard Reset that I read on HP's forum - pull the battery and the AC plug,push the power button and hold it for about 30 seconds release. I have reset the hard drive, memory, cd drive, and also tried using just one stick of memory but still same exact result. When I have the battery in and the ac adapter plugged in, the charging light is lit up blue. I have tried powering it on using just the AC adpater with no battery, just the battery, both, tried another good ac adapter but still same result. When the normal operation side of the computer goes bad, the car does. The theory is that the computer has 2 modes of operation: cold operation and normal operation. If the computer scans very quickly, like in less than 1 second, the computer is bad. Two seconds later, the laptop shuts down. Re: 2002 pontiac grand prix starts but shuts off right. I push the power button, Power light, hard drive light, and trackpad light come on. I have a friend's laptop which is a Compaq Presario F700 laptop that turns off the moment I turn it on.

Laptop turns on then off right away
