Re: Unexpected forced restart
Hi David, The maximum temperature for an Intel Core 2 Duo processor is 100ºC with an emergency shutoff at 125ºC. The processor will shut down using its thermal protection routines well before any damage is done. They're designed to work up to 100C if required but the fans should both kick in well before that and keep even a heavily working machine around 85℃. But I don't like to see my 17 MacBook Pro higher than 75-80℃. It used to get high when I had Vista running in Parallels, I now have Windows 7 and it does not hog CPU as much as Vista.

Greetings! I did not know that Apple Computers could get High. Well I guess, if Apple/Macs are green it may be a possibilty.

Re: Unexpected forced restart
For what its worth, and I could be wrong, but I had this problem some time ago and I seem to recall that it turned out to be caused by a dead internal battery.

Re: Unexpected forced restart
Hi Adrian Peter David, When a kernel panic occurs, a log of the event is usually saved in the file “panic.log” in the Mac HD Library Logs folder. Double click the panic log and a new console window will open. New panic logs are added to the end of panic.log.
