Modern processors are protected by THERMTRIP. Once the CPU gets over a critical temperature, THERMTRIP causes the computer to switch off instantly. There is no time for any log entry, if that is the nature of the problem. Such a shutdown does not involve software at all, and it doesn't get a say in the matter. Also, if the computer is getting that hot, the heat might not be good for the battery. The battery lasts longer, if the ambient temperature stays a bit lower. I would check the vent on the machine, to see if it is free of dust bunnies. If you have pets, that only increases the odds it is a problem with the vent. If you use a program like Speedfan (almico.com), you may be able to monitor the CPU temperature. It could be, that you have two fans, and one of the fans has stopped entirely. Paul

The battery's at the other end of the laptop so I doubt it's seeing much of the heat. > > I would check the vent on the machine, to see if it is free of > dust bunnies. If you have pets, that only increases the odds > it is a problem with the vent. I've cleaned out the vent and the fan fairly recently. It seems that sometimes if I poke the fan (with a paperclip) it will start up. Doesn't do this all the time and I can hear it running at different speeds. > > If you use a program like Speedfan (almico.com), you may be > able to monitor the CPU temperature. > > It could be, that you have two fans, and one of the fans has > stopped entirely.

That is a different problem One still missing piece of information we would have if you respond appropriately is what kind of Compaq laptop. If you would respond to my other queries, we will have the information needed to troubleshoot effectively. We would know how many fans you have and it they should be running all the time or not and maybe even where to poke it if it needs poking... Dust bunnies? I got your dust bunnies right here: http://www.theregister.co.uk/2009/11/13/ventblockers/print.html

Here is how to resolve missing Administrative Tools. However, if your system has malicious software present, this may not work or may not work for long: http://windowsxp.mvps.org/admintools.htm |
