Dear all,

I just received my new Thinkpad X1 Yoga, brand new, with a dock OneLink+

Both are running fine. But it is impossible to start the PC when the dock is connected: The screen freeze at the red square LENOVO display from the Bios, windows 10 pro doesn't start.

I have to disconnect the dock, et relaunch the PC to enable a normal start. After the start, I can reconnect the dock.

I updated all drivers, flashed the bios, latest FW of the dock and even resetted Windows, but without success.

Lenovo support wants to change the laptop (!), it's brand new!

I thought maybe one of the topgun member of this community might have a better idea.

Thanks in advance for any advice.
