========================
Detailed description：I have had my computer for almost 2 year. I have never had any issues with the docking station (USB C) were i have my external monitor and mouse and keypad connected. For two weeks ago the display stoped working. It lights up when i am connectint to the docking station but it gets no signal so after a couple of seconds it turns of.
I can also say that there is nothing wrong with cables or dock. The mouse, keypad and everything else works just fine...But not the display.
I have also tried to connect my other laptop (lenovo x250) and with that laptop everything including display works. So, there is nothing wrong with the equipment.

I see that in thunderbolt controll center it says that i dont have any thunderbolt devices enabled/connected...When using my other laptop it says that it has one device connected..

I have now uninstalled the drivers and reinstalled them. I still have the same problem (but now with errors at start).

What part of the computer is it that has to do with all data over the USB port?

Everything else on the USB-C dock still works just fine...But no image on the screen...It seems like that the computer dont understand that there is another display connected.

The thunderbolt is located in device manager under system devices.

Hello Charlie,
Can I have a screenshot of your Windows update history in the past 2 weeks, around the time that the issue occurred?
Hope you still have it.
Thank you.

Regarding the update history i was so upset last time so that i did a new installation...so no history. When i looked at it before i couldnt see any update at this time.
Now it looks like this:

It still seems like the driver for the thunderbolt doens have found any hardware...

It is empty

Hello Charlie,
So....you are using Win11 instead of Win10? and the issue happen with Win11 or Win10? or both?
Thank you.
