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.  

 

Thanks,

Mike

It's not wise to blow compressed air from cans into vents; it blows the dust into the lap interior, not out of it. Sometimes those cans will cause condensation on the object they are blowing on, also not a good thing. Let the unit sit overnight, try to boot again in the AM. If no go, it will have to be opened up to see what happened. Possibly a connector came loose from the force of the air stream.  As far as your hard drive, get a laptop HD to external USB adapter (try Newegg.com), connect it to your lap HDD and plug into a desktop USB port. You should be able to pull your data off that way. Something like THIS (be sure to read the user reviews for added tips).

So any tips on what I might do to get the laptop started?  It was starting until I used the compressed air. It is now getting power, just nothing is happening.

I will be taking it apart today.  Is there a schematic available for a step by step guide on how to disassemble the unit.  You guys sent me one before for a Toshiba notebook and it was great, very visual and simple.

Hi

 

Yes, there is official maintenance manual available which explains the dis-assembly procedures step by step.

 

Here is the link - http://www.hp.com/ctg/Manual/c01295820.pdf

 

Based on the symptoms you described, i suspect a Nvidia chipset failure. Your model is notoriously famous for this complaint.

After leaving it unplugged all night, I plugged the charger back in and it actually turned on.  I can barely hear the fan.  Did a couple of quick tasks and put it in hibernation mode.  Wouldn't wake up, waited over two hours, and shut it down.  Then retried and it is restarting.  still seems very warm.

Is there a way to check to see if the fan is operational?  Or at least check the temperature of the computer?
