T60: undock on external power loss
If power is unplugged/lost, we should undock the docking station.
The power loss can also be caused by the fact that the user removed
the thinkpad from the docking station without pressing the Undock
button/hotkey
first. Without undocking it on this event, the thinkpad LPC switch will
still
connect the Docking connector, which causes crashes when docking it again.
