it's generally considered a bit rude to hijack a thread...

it sounds like you want to control the governor on your cpu.
you can max out the cpu when on ac power if you like by
doing

echo 'performance'
> /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

then to go back to on demand do

echo 'ondemand' > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

your distro probably has some kind of script system that run on acpi
events (in debian the events are in /etc/apci/events)
