Check your BIOS. We don't have any default setup for this.

Etienne, you running gnome-power-manager? If you are, just change the settings
in gnome-power-preferences to set the brightness values when on AC and battery
to more suitable levels.
If you're not, try removing acpid and installing gnome-power-manager. You can
get it from my repo here:
