[German]Do Lenovo Yoga X370 and X380 Series Thinkpads have connection issues with the USB-C Dock under Windows 10 version 1903? And if it occurs with the 1903 version, it should also apply to the 1909 version (November 2019 update).

The topic hese ben send already to me in mid-October 2019 by blog reader Michael H. by mail (thanks for that). I confess, it slipped through the stack of many messages, but it didn't get lost. So I'll cover it up here in the blog again, maybe it helps other blog readers, or there is even a solution – then you can post comments.
The problem description
German blog reader Michael H. wrote the following in his mail about the troubles which Windows 10 and the hardware is causing:
We are lucky to always be at the forefront of IT technology. Unfortunately, we are also facing various issues with Windows 10 or the hardware we use.
Currently, the problem of Lenovo Yoga Thinkpads of the X370 and X380 series having connection problems with the USB-C dock is becoming more and more common.
Since it doesn't seem to be a direct hardware problem, it's always difficult to bag something like this from the manufacturers.
The problem is that the notebooks hang as soon as a monitor with display port is connected and switched on.
Sometimes the display on the notebook turns black, sometimes the mouse is gone and touch cannot be operated anymore.
If the monitors are switched off, the notebook works again.
Drivers, firmware (NB and Dock) and also Windows 10 1903 are up to date. We also had this problem with 1809.
This immediately rings a bell in the back of my mind, as I had published the article urface Pro 7: Firmware update for Battery and USB Dock at the beginning of December 2019 due to a similar error.
Other mentions within the internet
German blog reader Michael H. pointed out in his mail that there are numerous users on the Internet who are complaining about the dock problem with USB-C. Here are a few links to German and English forum posts about that issue.
- Displayproblem in Verbindung mit Thinkpad Dock (USB-C)
- ThinkPad USB-C Dock Gen 2 and multple monitor problems
- USB-C dock external monitors not working on L370
- ThinkPad USB-C Dock Gen2 – Black Screen, USB Audio Issue & Firmware Upgrade
In the last linked article the user also has firmware upgrade problems. In none of these forum posts I found a solution. But other users confirm the problem. Can anyone confirm the problems? Is there a known solution?
