Question about HP Compaq Presario V2000 Notebook
Yes its probably the fan but it could also be the screen brightness. replacing the fan and turning down the brightness will cool the laptop. but i agree try a new fan first.

This is an easy fix if you're comfortable with taking your laptop apart. What has happened is the thermal grease in between the cpu and the heatsink has dried out, and is not conducting the cpu's heat properly. The machine is shutting down to protect itself. My best advice is go to any computer store, and get a tube of thermal paste, and find the disassembly instructions online. Clean both surfaces (the heatsink and cpu) with rubbing alcohol. Re-apply a thin layer of new thermal grease, and reassemble. Be sure to clean the crud out of the heatsink while you have it out.

I have a toshiba laptop which was unexpectedly switching off. The laptop was 2 years old. I did lots of searching online to discover this is a VERY COMMON ISSUE. The problem is, dust blocks the heatsink. When I took my computer to pieces, I found a strip of dust half an inch (1cm) thick covering the back of the heatsink which prevented air flow. If your laptop is a couple of years old, this could be the problem. When I removed this dust, the problem disappeared. If you are computer savvy, then try the following - if not, take it down to a computer shop! 1) Remove the 5 screws holding down the heat sink cover and processor cover. These are on the bottom of the laptop, in the centre, at the back. 2) Remove the 3 screws which hold in the heat sink in place. 3) Remove the heatsink 4) Take the dust out 5) Re-assemble a note: be careful not to get dust in the thermal paste on the cpu - unless you have replacement paste. Good Luck!

Check for BIOS updates at the Compaq support web page. I have a similar V2555US model and there was a BIOS update to fix a problem where the cooling fan wasn't coming on when it was supposed to. After the BIOS update, the fan works perfectly.

The cooling fan should automatically kick in before the laptop shuts down. If the fan is turning on then you should feel a warm breeze of air being forced out of the bottom left hand part of the laptop. If the fan is on but no air is felt then you might have a dust blockage. You can try blowing it clean with canned air but you will probably have to disassemble and clean. If the fan isn't coming on or the blades move very slowly or stop then your fan is probably defective or clogged badly. Again try cleaning or if that doesn't work replacing the fan. Looks like the fans run about $50 to $70, however, don't attempt disassembly unless you are confident you are up to the task. This isn't a particularly hard job but you will need to remove screws and mess around with fragile plastic parts, not a task for the typical computer user. Good luck and let us know the outcome.

mine was doing the same thing....i think you will find 9 times out of 10 the thermal paste has dried up.....i looked on google and it took me step by step through the process....im a total novice and it was really easy..will see if i can find the link for you.....Tina xx

hi ashok, it's a major problem with the Compaq laptops...
as they donot provide display & audio drivers with the system!
you should search the drivers on google search using ur Model no. !

Follow-up response to solution posts by Pontelemon and Gurutim: so you think it's still due to overheating, huh? OK... I'll follow your lead and reduce the thermal grease and post back results next week... I'm betting you guys could be right!...
