My Yoga works fine with Thunderbolt 3 eGPU when i put it on when Notebook is running.
If I try to restart or turn Notebook on with eGPU Dock I get no signal for screen. Not on Notebook Display and not on external Display. There is no way to get a signal on any Port or to change output. The only Way then is a Hard Reset. After that everything works finde, even the eGPU.
I tried this with Razer Core X and HP Omen Accelerator and Razer support said its a Problem with the Thunderbolt3 Driver.
Anybody had this Problem too?
I tried Drivers from Lenovo and from Manufactures.

Thanks for Reply.
All Drivers and Firmwares are from Lenovo and are up to date and I also did the bios update. The Problem still occurs.
I even tried Drivers from Intel Site but still the same Problem.
Any more Ideas?
Do you think it could be a Hardware Problem with USB C/Thunderbolt Port or Controler?

I did a Hardware Scan and found out that there is a failure on Motherboard Pci / Pci-E Test.
The button to send results after Hardware Test is grayed out even if I am logged in.
Is ther no way to open a support case online for this product?
