No charger, no usbc devices detected in session only when suspended or restart

Support
1

Hi,
I am running 5.11.6-1-MANJARO KDE Plasma on a Lenovo thinkpad carbon x1 Gen 7 . Since a few months (maybe since upgrading to Kernel 5.8 or something) I have problems with connecting any usbc / thunderbolt / charger. When the system is running no device will be detected plugged into the usbc ports of the laptop. Does not matter what: keyboard, mouse, display, tb device, … even the charger will not be recognized. However, as soon as I suspend, or reboot the device is promptly detected. Also all devices connected while starting the system are detected. Just not while running. Does anyone have ideas, or similar issues?

I checked, and in the bios the problem is not present.; charger is detected. And any device will work properly once connected to the system. Also thunderbolt devices. And the other USB ports work fine.

I updated to the latest firmware via fwupd. No changes.

I attach some journal log output from when I am disconnecting a thunderbolt display and then trying to reconnect. But there is nothing at all in the log. I don’t know where to start.

Here is the output from journalctl:

When pasting terminal output, highlight it and use the Preformatted text </> button.

Alternatively, add three backticks ` above and below the text:

Hi, just an update: I found a fix for the problem. In the end it was hardware related. The problem first got worse today, and the laptop suddenly stopped charging completely. Then I noticed the weird behavior even if the laptop is completely turned off.

Finally, I found that this might be related to faulty charger / battery chip problem. The solution was to use a paper clip to press the battery reset button on the bottom on the machine (information from the Lenovo carbon x1 manual). This completely disconnects the laptop from the battery. Voila everything worked perfectly afterwards. Thanks for everyone looking at this. And if you happen to have a similar problem, this could solve it possibly.
