IBM and Lenovo ThinkPad laptop enthusiasts!
You could try the little reset hole on the bottom of the laptop.
I had some weird issues with my z16 none of the usb c ports were working and neither was the usb c dock.
I think there must have been some static buildup or something that triggered a surge protection or something but for me using the reset pin hole did the trick
Just have a read up on doing that for your model
It’s doesn’t wipe the laptop. Just resets the power circuit or something
IT'S WORKED! I don't know really why, but thank you very much, I already scared about it, but right now port is working!
Noice!
You can try to see if lspci sees the USB controller. Next I would try running diagnostics from UEFI, see if you get any errors. Try a bootable USB to verify if it’s a hardware or software issue.
Any hardware diagnostic failure or failure to boot from it will tell you you need a new system board.
