I have a Lenovo X1 Carbon Gen 12. The other day I noticed both of my USB-C ports are not receiving or sending data. External drives won’t mount and my dock won’t send signal to my monitor, but when I plug in my charging cable I am still getting power. When I use “lsblk” nothing shows up, even though sometimes I hear the chime signaling something has been plugged in (but it’s inconsistent and sometimes doesn’t chime).

Both of my USB-A ports are working properly and receive data, so it’s only my USB-C ports.

I’m running Ubuntu 24.04.3. I tried to revert back to an earlier kernel in case that was the problem but it didn’t fix the issue.

Anyone have a similar issue? Thanks!

    X1 Carbons of several generations have been notorious for their Thunderbolt defects, which appear after a while. For instance this or this (sorry for the Reddit links), and there are others related to connecting to screens. Right these days I’m dealing with the Thunderbolt-charging defect in my Gen 9. Luckily still under warranty.

    Best of luck with your problem! I suggest you use your warranty if still active (and better with on-site assistance than sending the thing).

      Thanks for the reply, sorry didn’t see until now.

      Yes, what ended up happening was the computer was still under warranty and had Lenovo premium service (I didn’t pay anything extra for it, maybe it comes default with the X1 Carbon?), so a tech came out a day later and replaced the motherboard. It was actually super simple and I was back up and running in no time. I haven’t had any issues since.
