My notebook has a habit of getting hot, and Centos just shuts down. Just did it again:
Jul 15 01:35:12 nc4010 kernel: ACPI: Critical trip point Jul 15 01:35:12 nc4010 kernel: Critical temperature reached (113 C), shutting down. Jul 15 01:35:12 nc4010 kernel: Critical temperature reached (55 C), shutting down. Jul 15 01:35:13 nc4010 shutdown[9847]: shutting down for system halt Jul 15 01:35:13 nc4010 gconfd (rgm-2904): Received signal 15, shutting down cleanly Jul 15 01:35:13 nc4010 gconfd (rgm-2904): Exiting
What I would like to know is where are the threshholds stored?
It would be nice if some alarm went off (like with low battery), giving me time to grab the blue-ice block out of the freezer (or at least saving some work and pointers!).
Well I don't know really well and there is not much documentation (easily accessible via google) but you can check /etc/acpi/events
In theory you can execute a script when a given acpi event occurs, this includes power button press, closing laptop lid, etc.
You can look up at the proc interfaces for acpi for some clues too:
/proc/acpi
As events seems to be closely related to them, maybe you can catch an event from thermal_zone and the execute an script to let you know that your laptop is getting too hot, I'll check on this as it may be useful for me too.
Good Luck!

thats WAY hotter than your system should be getting.
I'd open it up and make sure the CPU heatsink isn't full of cathair or something. make sure the airvents aren't blocked when you're using it, too, and that the fan is working.

I would also check that you have CPU freq scaling on (the cpuspeed daemon) - as your system should NEVER get this hot.

What/where is the CPU freq scaling and the cpuspeed deamon?

I do need to open it, but then I have to shut it down ;)
The last time it did this (a week ago), I shot all the vents with air, and a lot of dust came out the other vents. So I should open 'er up.

Oh, I can hear the fan running. Off, slow, fast, off...
