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.

You might want to try a better thermal compound, Arctic Silver or
something like that. Also make sure that you don't use too much thermal
paste, a little dab will do ya.
