Perhaps it wasn't the fan but the cpu who was overclocked ?
Anyway an acpi issue, then.

Hmm... how to find out ?
It would first find out if there's a timeout (idle time after that the event
btw is the battery status recognized correctly (at least the fact it's
plugged into main) ?

Yes, of course. Just for completness.

ok...so i guess it's more for real acpi specialists ... sorry that i butted I
just like weird problems, true. I'm sure anybody else on this list can help
you more than me. (Perhaps they're on holiday ?)
t's said on the developer.intel.com site one should attach the dsdt to
problem reports. However, my impression is the device table to be more
important with booting problems.
Hey, there _must_ be some people around the world running exactly your laptop
with linux ! Some of them with acpi working ....
Perhaps you ask the acpi (+/- developer) list if there are any problems known
special to yours.

Just for some standard overview, when psoting problems to experts
( t.i., the acpi-developer-list, e.g.). Anyway sometimes external devices or
internal chipsets tell stories...

No idle-time ? The other two cases i know are battery low and cpu overheat.

Probably (but not prooven) right ! ;-)
If you would know the time span, you could possibly arrange an 'at' job (with
atd, the at-daemon) Just wild ideas, you see.
... Anyway better you'd find the event handling ... i imagine somthing
similar to /etc/apm/ directory here. 'man acpid' must reveal this, if it
exists. But maybe all echo > /proc/acpi is done by 'frontends' now ?

klaptopdaemon ? sleepd ? daemons are always suspisious. It's their nature ;-)

Something ! It's funny, isn't it ;-)
Usually, I'd say this is the BIOS, then. What does it's config say ?
One more idea. There's a powermanagement-option in /etc/XF86Config-4.
It's for 'green' monitors, not for laptop-lcd's, afaik. But wdikaa...
I'm not sure how KDE settle things down. If once configured some 'flags' (or
files) would'nt they stay until somebody's gonna change things again ?

If this is not existent i would wonder if the patching was alright...
( btw. perhaps you try kernel 2.5.6 ? But i can't say what this would imply
to install, then. Perhaps someone else on this list is running a 2.5 kernel ?)
I think what we really do need is a dedicated laptop distro.
If i remember right, Werner Heuser proposed this already...
