Hi all,
I’ve run into a problem with the USB-C port on the right side of the Librem 14.
I understand that this is the one that should accept power delivery and provide display out. Neither of those functions have worked since day 1 of having this machine, but while it served as a USB port, I wasn’t too concerned. Now, however, it doesn’t recognise any devices connected to it.
(I’ve treated this laptop like royalty, so there’s no physical damage)
I’ve updated using the EC tool (v.2.5_2021-10-28) and have updated Pureboot to v20 using a stock image. No change.
Is there some script available that I might be able to run to determine the nature of a hardware fault? I’d prefer to try to diagnose/repair here rather than ship the machine back to Purism.
Any thoughts would be much appreciated before I open a support ticket.
Thanks in advance!

I don’t know if something is missing from these outputs because I don’t have a fully-functional L14 here to compare it with. As I said, any suggestions would be great!
