Matthias _is_ right, you need a power management daemon to tell
laptop_mode when it turn it on or not. Laptop_mode is _no_ daemon that
checks for ac power or not periodically.
Your case with LAPTOP_MODE_ALWAYS_ON is special.

But it decreases the lifetime of your hard disks servos due to frequent
spin ups and spin downs.

There's no other sensible way, you can always delete the script that
handles laptop mode from pbbuttonsd, it won't reappear on upgrades since
it's a conf file.
