# anrxc's acpid handler for Acer TravelMate 5320
# 
# Power button starts a system shutdown.
# Sleep button suspends the machine to ram.
#   - delegated this to my WM (Fn+F3 to disk, Fn+F4 to ram)
# AC events control CPU throttling.
#   - now they start laptop_mode which also takes care of that
# Battery events should auto-hibernate on low battery trough laptop_mode.
#   - my battery doesn't report back and has no alarm support
# Lid handler locks the screen when someone tries to open it.
#   - there is no need for it to be running while lid is closed
#   - included are commands to power on/off the panel
#     - that's automatic on my hardware
