Yes - shutdown.  Is 92 degrees actually ok for a Pentium M?  Seems
awfully hot, but I haven't looked at the specs.

You've reminded me I don't have the latest BIOS, if that's responsible
for shutting down a laptop if it overheats.  But can it be?  I'm using
ACPI (obviously) - can't the OS decides to initiate a shutdown too?
I could swear last time it happened that it was well signalled as
being shut down by the OS, not just a crash wallop.

Having said that, I've been doing a 100% CPU compilation just
now for 30 minutes or so (kdemultimedia SRPM rebuild) and the CPU
temperature is varying between about 70 degrees and 85 degrees.
The fan is changing accordingly, from 3500 to only about 4000 - which
doesn't seem a dramatic increase to me when so hot, as it runs at 3500
permanently even when idling.  I'd be very happy for it to double in
speed, make more noise, and cool me down a bit more.  I'm wondering
if other people's fans go quicker than that in T40s/other Ts under
high sustained load..

Marcel thanks also for your comments - I'm under warranty so could
ring them - hmm.
