Hi,

I also had this driver crash issue with my T480 and the ThinkPad Hybrid USB-C with USB-A Dock. Displays connected to the dock randomly went black and I had to disconnect/reconnect USB3 calble to fix this. I tried Displaylink beta -drivers, but they didn't fix the problem.

Lenovo published a new BIOS update (1.36) for T480 and it contained the following fix:

[Problem fixes]
- Fixed an issue where monitors attached to Thunderbolt 3 Dock Gen2 are
disconnected when battery charging is reached to 100%.

I managed to regenerate the problem and updated BIOS. I haven't got any crashes after the update.

Kind Regards,
Mikko
