suspend on laptop overheating

Hi


Lately I've had many overheating problems with my laptop (hp pavilion
ze5700). Maybe that model is not well-desingned for the heat here.

The laptop shuts down at the temperature of 73C by running 'init 0'.
Until I figure if this is a hardwre issue (or until winter comes) I'd
like to change the action it initiates in case of overheating.

I use swsusp2 (currently with kernel 2.6.18-rc1). The system is Sarge,
with a manually-backported 'hibernate' package 1.91-1bpo1 . 

I have acpid running, but I noticed no event in the case of
overheating.

I do get the following in my logs:

Aug 21 00:02:33 localhost kernel: ACPI: Critical trip point
Aug 21 00:02:33 localhost kernel: Critical temperature reached (73 C), shutting down.
Aug 21 00:02:38 localhost kernel: ACPI: Critical trip point
Aug 21 00:02:38 localhost kernel: Critical temperature reached (73 C), shutting down.
Aug 21 00:02:39 localhost kernel: Critical temperature reached (72 C), shutting 
down.
Aug 21 00:02:40 localhost kernel: ACPI: Critical trip point
Aug 21 00:02:40 localhost kernel: Critical temperature reached (73 C), shutting down.

This is followed by a shutdown.


I would like to change the command it runs to a script that will
basically run:

  hibernate || shutdown

Any relevant RTFM?
