Some Thinkpad laptops' firmware will initiate a backlight level change request through operation region on the events of AC plug/unplug, but since we are not using firmware's interface to do the backlight setting on these affected laptops, we do not want the firmware to use some arbitrary value from its ASL variable to set the backlight level on AC plug/unplug either.
