Notebook is about 3 months old, my TB16 dock worked fine since day one but suddenly as of friday a week ago charging no longer works via the TB16 Dock.
What I tried
As I am running linux by default I am sure that on the day it stopped working I did not do any bios/driver whatever updates.
As it's also not working in Bios it should be OS/driver agnostic.
Any idea what's wrong or what I could do?
The dock works normally apart from that - usb devices and display link monitor are working fine.
Solved! Go to Solution.
Same here - technician dropped by, swapped the motherboard and it's working again.
No dataloss btw. altho it's recommended to do a backup just in case.
I am still in contact with Dell France. A last test to perform in the next days with another XPS, and if we confirm the XPS is faulty, then the motherboard will be replaced (it seemed it was not a surprise for the tech I had on the phone).
For those who had a tech change the motherboard, did you get any information on whether this new motherboard has a component that will not fail?
Any word from Dell about this issue that seems repetitive? Is the new component more durable?
The tech that worked on my laptop said he has seen same or similar issues across many brands and models that have a USB-C dock. His theory is that the dock cable end is too big for a USB-C port. Failures may be coming from movement of the cable and / or stress on the port.
Just finished my 5 week dance on this. Laptop sent in, tech notes said "Logic board replaced". Works again.
Piece of advice, if it worked before and no longer does, start the service claim immediately. Don't waste hours and weeks of your life with the "driver update/support session" dance...
