USB Ports Dead after undock and redock P53 in Thunderbolt 3 Workstation Dock after BIOS update

2020-01-23, 8:46 AM

After the latest (almost mandatory according to alert) BIOS update of my P53 I cannot undock and redock without rebooting. The dock is recognized but the USB ports do not work after redock - the display does. It is the same on two different docks with newest and second newest dock firmware.

 

First Lenvo support would not help at all - said it was a software problem - and now they after me complaining want to take the machine in for repair. I doubt it is a hardware problem but just a side effect after updating the BIOS.

 

If I boot docked - everything works. If I boot undocked and dock one time - everything works. If I undock and redock - the docking ports do not work.

 

Anybody else with same problem and a solution?

 

No way to get "real" qualified help from Lenovo on such an issue. It takes forever to reinstall and setup all software and tools on a workstation and just re-formatting and re-installing Windows (advice from support) with is not way to solve a problem induced by Lenovo in my mind. It is an expensive computer and expensive docking stations - but apparently no real support.

If you disable Intel VT-d Feature in BIOS, it might start to work - mine did - almost
