My P25 was overheating and shutting down during CPU intensive tasks
like making .iso files.  Reinstalled that particular prog but  it
still shutdown.  Avoided that prog until one day it shut down
downloading files with many other windows open.

Downloaded several monitoring progs but this is the only one that
would pull the CPU/HD temps from this Toshiba BTQ00 motherboard;

http://www.hmonitor.com/

CPU was running like 72C.  Checked the Intel site and they listed the
thermal limits as 69/70C for my CPU.  Found this site;

http://www.irisvista.com/tech/laptops/ToshibaP35/SatelliteP35_fix_overheating_1.htm

.  The site has a LOT of Toshiba laptops and directions/pics on
tearing them down.  Tore it down, blew the crap out of the heatsinks
and it runs great now @ 42C.

Problems;
Like most 'puter manufacturers, Toshiba used a TIM pad instead of
thermal compound.  When I pulled the heatsink, the CPU came with it!
CPU wrenched out of the ZIF socket.  You/I CANNOT just put it back.
The ZIF socket 'lever' that locks the CPU in the socket is actually a
cammed screw.  It CANNOT be reached with the heatsink covering it.
I cut off the CPU with a single edged razorblade, cleaned heatsink and
CPU extensively with alcohol, and put on a nice layer of Artic Silver.
Replaced the heatsink, evenly tightened the spring loaded screws on
it, and all is well.  Since the Artic Silver won't harden, I'll be
able to tear it down in 5 minutes next time I need to clean the
heatsinks.  On my P25 a single access plate is all I need to remove.
5 Torx screws and I'm looking at the heatsink.

I do NOT recommend tearing your CPU out of the ZIF socket like I did
in my ignorance.  However if you can get to the heatsink/CPU quickly
enough while it's still warm, the TIM may be more malleable.

Good luck!
