Windows 8.1 and Lenovo X1 Carbon Monitors don't work

[TargusLevel3]

Targus is aware of a hardware issue that has recently been diagnosed with some ACP70 docks. This issue is most easily recognized in the Windows Device Manager where no USB Display Adapters and no Targus Giga Ethernet Network adapters are present. It is also when neither of the dock’s display ports or Ethernet ports work at all. The issue is intermittent and temperature dependent, showing up mostly at colder temperatures. Manufacturing has produced at ECN for a workaround for all newly manufactured docks but for deployed units that exhibit the misbehavior, please contact Targus for a free exchange.
