Laptop - Trigger custom power management script

I wish to trigger a custom script to run when the AC power is unplugged and then when its plugged in again.

I assume there is a folder were I can place my script.

Does anyone know how I can do this?

Thanks

cat /etc/laptop-mode/laptop-mode.conf

Thank you for your reply.
I found what I was looking for...

in /usr/lib/pm-utils/power.d/laptop-mode

laptop_mode_ac() {
# disable laptop mode, set vm parameters back to sane defaults
if state_exists laptop_mode_default; then
write_values $(restorestate laptop_mode_default)
else
write_values 0 10 5 500
fi
---> insert script when on AC /folder/my_script
echo "Laptop mode disabled."
}

laptop_mode_battery() {
# enable laptop mode, set vm parameters to buffer as many writes as
# possible.
state_exists laptop_mode_default || \
read_values | savestate laptop_mode_default
write_values "$LAPTOP_MODE" "$LAPTOP_DIRTY_RATIO" \
"$LAPTOP_DIRTY_BG_RATIO" "$LAPTOP_DIRTY_WRITEBACK"
---> insert script when on Battery /folder/my_script
echo "Laptop mode enabled."
}

Just for sake of completeness, cpufreqd can also do that. Actually a bit more than that, because each rule can execute commands and you can have multiple rules (like AC power, AC + program XX running, battery more than x% and cpu use less than 10%, etc)
