Public bug reported:
This only happens to me when I connect my USB-C docking station to my
laptop. The laptop doesn't really turn off and goes crazy. To solve this
I have seen that disconnecting the battery from the BIOS settings solves
the problem. If I don't do this the laptop never really turns off and
drains the battery. But when I start Ubuntu and restart it a couple of
times it happens again.
Dock: Thinkpad dock station Universal usb-c (upgraded the firmware to
the last version for see this fix the problem)
Laptop: Thinkpad E490 (bios upgraded to the last version)
Run Ubuntu 22.04 (All upgraded !!!)
kernel: 6.5.0-21-generic (with the kernel 6.5.0-18-generic same thing
happens)
On the same hardware configuration settings run Ubuntu 20.04 and i dont
have problems.
Regards!!!
