Here's a little tip I discovered that may be of some use:

I have a thinkpad A31p. It's a great machine, and I've been running gentoo on it for about a year and a half with no problems. However, recently I noticed all sorts of odd things happening. I would load back some of my code, and I'd would have all sorts of weird accented characters in it, and thus wouldn't compile. And it crashed a lot.

I checked my ram with memtest86, and my hdds with badblocks. No errors showed up, so I installed gkrellm2 and kept an eye on my cpu temp. When pushing my system the temperature was soaring above 80C. Hence the crashes and corrupt files, I guess.

Anyway, I investigated all of the solutions about polling /proc/acpi/blah, but that all revolved around reducing my CPU speed when things started to heat up, and being a speed freak, I didn't really like any of those ideas.

I tried to open the thinkpad and clean it. It used to work at full load all the time, no problems. I could emerge openoffice and kde in one sitting without any loss of stability... - No dice there though. The thing is built like Fort Knox. I could get all the screws, and *some* plastic bits off, but I couldn't get anywhere near the CPU or fan without fear of damaging it permanently.

So, I went to the local hardware store and bought three round rubber doorstops. (The kind you screw into the floor) - I've been keeping them in my laptop bag, and every time the temperature starts going up, I put them in a triangle under the laptop to lift it up off whatever surface I'm using it on and get some airflow underneath (which is always the hottest part). As soon as I do this, the temp drifts back down to 60C, and stays there.

I've emerged gnome 2.6 without it going above 60C, it stays there all the time I'm using it, and I've had no more random crashes or corruption. It's works great!

Now, if anyone could tell me how to open a thinkpad A-series without damaging it, I'm all ears.... :-)

Another tip: if propping the laptop up doesn't cool it off enough and you have a desk or something that you commonly work at, having a small fan provide a cross breeze under the laptop will help a lot too.

That's a nice solution. My dad uses a cookie drying sheet with his Gateway laptop, for the same reason.

As for opening the laptop, you're lucky to have an IBM, since detailed repair manuals are available from IBM's website. I've used them for my Thinkpad T21 before, and they're really exceptional. Search around for the manuals for your specific model, and you should find some PDFs to step you through the approved way to dismantle the device.

Good luck!

Also blowing some compressed air through your cooling vents can get a lot of the dust out that accumulates over time.

How about sticking it in a fridge! :)

And yes, I've actually had to do that. I'm still bitter, thankfully it wasn't my machine.

This one is a killer:
turn the darn thing off, before it burns your balls to oblivion :)
my laptop, a hp omnibook, is so warm that the fan works it's ass off, constantly - the tempurature is probably so scary that I should be ashamed to still have it running - but since I never have got my omnibook-module to work properly, I don't care :twisted:
