    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.
