From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

USB-C ports no longer sending/receiving data (Lenovo X1 carbon) (lemmy.world)

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!

Try to boot up an OS with a USB stick on a usb port you know works and see if the USB C ports start working. If they don't, it's probably a hardware issue. If they do work, it may be a driver issue.

Hmmm. Booted a live version of Ubuntu off a USB stick and got the same result: No mounting of a thumbdrive on USB-C but it worked on USB-A. This is the second time I've had something like this happen with Ubuntu. I bought an X1 Gen 9 and the computer just stopped recognizing the battery. I was within the return period so I just sent it back and got the Gen 12. Now, I'm having a USB-C issue.

I haven't had any damage or physical issues that would explain a loss of the usb-c ports. Additionally, the ports still work to charge the computer, so they physically must be working (at least in some capacity). I'm stumped.

Edit: Now that I think about it, the only thing I can think of is that I recently bought a UGreen 65W power brick. It's the same wattage as my official lenovo charger. I wonder if that is behind it.

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.
