Hi, I have a question for you that's a bit important, I have a Fujitsu
Siemens Amilo A1630 notebook with a AMD Athlon 64 3700+ installed
(running Vista x64 and Ubuntu 7.04). Two days ago, I was playing with a
game and suddently the PC shut down. I turned it on again and I had the
same problem, and since that day this problem occurs every time the
processor is used in a heavy way (only using it @ 800Mhz seems to keep
the machine alive).
I used RMClock in order to run the processor at its real speed (2400mhz)
because Windows Vista does not provide Cool 'n' Quiet Drivers to do it.
The same problem occures now also in Ubuntu, that in the loading phase
shuts down when a fast processor speed is required. I started thinking
that the problem could be connected with a damage occured to the CPU the
first time it shut down while playing that game - maybe for a
overheating reason.
Someone could help me?
Thanks a lot!!!

It's a heat sink problem not a CPU problem. I had a similar problem on my
Compaq R3000z (A64 3400+). The heat sink was full of dust. I removed the
heatsink, cleaned it off, cleaned the surface of the CPU and the bottom
of the heatsink with alcohol, put on a little Zalman thermal compound and
reattached the heatsink. I can now run the system at the maximum clock
rate under full load, prior to doing the cleanup job the system would
crash at clock speeds greater than 1.8GHz.

Laptops have small heatsinks so there isn't any margin, if they are dusty
they can't do the job. Unfortunately you can't just vacuum the dust out,
the cooler assembly is buried inside of the laptop. You will have to go
to the Fujitsu site and find their maintenance manual. On the Compaq the
job turned out to be fairly easy, all I had to do was remove the back of
the laptop. The cooler was held in place by four spring mounted screws,
it was actually a lot easier to get it off and back on then it is with a
desktop cooler.


It is exactly what I did, in my case I also removed the heatsink,
cleaned it and verified the contact with the processor. Now it works
much better than before (the noise it produces is much better and it
generates much more air).
But the problem was not solved.
