Can a failed Thunderbolt Port be repaired

I have an XPS 15 9575 purchased two years ago. About 3 months ago one off the Thunderbolt ports quit working. Dell wouldn’t help since the PC is out of warranty. I am trying to find any help I can with this problem. Diagnostic help would be a good start. Is there anything that can be done with this issue or am I stuck with a non functioning port forever?

Hey Art,

You could check to see that the port is enabled first in the BIOS. I believe to get into a Dell you have to use the F2 key on boot. The option you would be looking for is under ‘System Configuration’ then under ‘USB Configuration’. From there you can change the Thunderbolt port settings.

You can try checking for drivers as well. Try uninstalling the port in device manager and allow it to be re-found.

Hope this helps!
