Hot CPU: system automatically shuts down

Hm, i had this problem (albiet desktop) and I just took the heatsync off, cleaned it and added some arctic silver to it which fixed the overheating, dont know what it will be like in a laptop

I finally wrote a small guide to the cleaning process:

Disassemble a Toshiba Tecra A7 Notebook to clean the CPU fan

Hope you find it useful.

Toshiba is apparently really bad at designing efficient colling systems in laptops and they never learn to do it better. I have two old Toshiba laptops, Satellite A30 and Satellite M35 and both suffer from overheating issues. I had to learn how to disassemble both in order to clean them out periodically. After having an experience like this with my second Toshiba laptop I vowed never to buy anything made by Toshiba again.

68C is still pretty high, by the way. It's no longer a risk of hardware damage, but I imagine it does decrease the comfort of working with the laptop significantly. I'd recommend looking into undervolting using PHC kernel patch. By undervolting the processor on my second Toshiba I managed to get it to stay under 50C with no perceivable effect on performance. This allowed me to finally use the laptop without burning myself on the touchpad and it actually became a very nice machine to work with after that. The added bonus is that the fan almost never has to come on, so the laptop remains completely silent most of the time, which is great.

My sister has a toshiba A215 or something like that, and it had a problem with it getting extremely hot. I took it to a repair shop (under warranty) and they said it had a bunch of "dirt" in it. They claimed to have cleaned it out and it runs considerably cooler. She was/still is running Vista, but it seems, as others have said, toshiba has some design flaws. My sister didn't keep her laptop in dust/dirty conditions either :-/

@fwojciec 68 C was the temperature reached after 1 hour of 100% CPU processing. With normal usage it is around 50 C so I'm pretty OK with it.
