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!
