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.
