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!
That’s possible. Not all physical damage on a computer is visible to the naked eye.
If your computer has a selective USB suspend setting, try turning it off.
Alternatively, try pulling the battery out, holding the power button for several seconds to drain all power from the machine, then putting the battery back in and seeing if that does anything.
