Hi to all, my right usb c works again... I have absolutely no idea what made it work again. a) I never got any help from DELL support b) yesterday my battery was completely empty so I left it charge overnight. When I opened the laptop today I got the message that Windows cannot boot.. so I selected advanced troubleshooting but the system did not detect where the problem is, so I just selected the option to try to boot again.. And it did without any problem. Then I was curious to check the right usb-c port... and it works again now. Hope this helps at least one more owner of Dell XPS   just to let all of you that may experience similar problem
This morning I got notification about recommended BIOS update... so I let it run...once the update completed my usb-c dock on right usbc port stopped working (when I connect it to left usb-c port it works). I tried even other dock .. same result, not working on a right usb-c. Since I have my large monitor, mouse and kbd connected to it I would need to make it work again asap. What I already tried: - rebooting, power off/on : several times - latest bios update reinstallation (completed OK)
