I would assume this is discovered through ACPI...

A quick google turns up the kind of thing you would need to know:

http://www.tldp.org/LDP/LGNET/current/pramode.html
http://www.gelato.unsw.edu.au/linux-ia64/0201/2778.html

Plus, there is a thing called acpid - this can probably fire off various
scripts on ACPI events, such as buttons being pressed, laptop lids being
closed, etc...
