USB C port doesn't work on laptop, how to troubleshoot? (hilariouschaos.com)

I got a Dell Latitude 7400 2 in 1 from my job they were going to ewaste. I daily drive KDE Neon on it and I love it. However, one of its two USB type C ports isn’t working for charging or data transfer. I inspected the port but found no obvious damage. How can I troubleshoot and fix this? I’ve searched YouTube and online sites but haven’t found helpful guidance.

Assuming you haven't, and also can (I'm sure dell didn't want you poking around in the laptop), I would suggest taking the bottom cover off and looking at the solder joints on the port, or daughter board with the port on it if it has one, or both!

Definitely done that but no obvious signs of damage there. Also tried seeing if the port wiggles to indicate poor/weak solder points but none there either. It’s still on there as if it came stock. Thank you for the advice!

You're welcome, even if you already tried it! Good luck figuring it out!
