U2718Q, USB 3.0 Upstream cable, Windows shows Power Surge message

* For testing, the U2718Q power cable should be plugged directly into the wall power socket. Not into the same power strip as the computer
* You should be testing using the supplied U2718Q USB 3.0 Upstream cable
* Disconnect any/all USB devices plugged into the U2718Q four USB Downstream ports. Then retest for the power surge issue
* Reconnect any USB device (mouse, keyboard, HDD) to any of the four USB Downstream ports. Do those devices function?
* For my notes, what is the full 20 digit serial number and A0x revision number (NOT the private service tag number)
* Can you replicate the U2718Q USB hub issues when connecting the U2718Q to a different computer?

I will add that I have the same issue. This is a Dell U2718Q monitor plugged into an XPS8910 using the supplied upstream and power cables that came with the monitor. The monitor is plugged into a wall outlet and no downstream devices have ever been plugged into the monitor (all equipment less than two months old).

* Have you had the issue this entire 2 months?
* When you connect USB devices I am asking you to test this (mouse, keyboard, HDD) to any of the four USB Downstream ports, do those USB devices function?
* For my notes, what is the full non-private, not connected to your personal information in anyway 20 digit serial number and A0x revision number (NOT the private service tag number)
* Can you replicate the U2718Q USB hub issues when connecting the U2718Q to a different computer?

1] The issue started when I bought and connected the U2718Q with USB 3.0 to the XPS 8910. Prior to that I had a 5 year old U2312HM with USB 2.0 connected to the XPS 8910 without the issue occurring.

2] No devices are connected through the USB ports on the monitor

3] There's no other computer to replicate the issue with.

Based on the lack of call logs pertaining to this complaint, we do not think that the fault is with the monitor. If it was systemic to the monitor, we would be seeing thousands of the same complaint. Most likely, this is a  Windows driver issue. Run the Intel update utility and install any drivers it finds needing updates. Then restart the computer and retest.

Also, test a wired USB mouse or wired USB keyboard on all four (two side/two bottom) of the U2718Q USB downstream ports. Does the wired USB mouse and keyboard work in all four ports?

HI, in my case it was a faulty unity. Dell replaced the monitor and everything os working fine

Faulty monitor serial number CN-04K-8X7-QDC00-795-0FKL-A01

Thanks for the serial. Will add it to my notes. That A01 was manufactured on September 5, 2017.

I ran the utility and no updates were required. I will try the wired mouse and keyboard in all four ports and respond back. Thanks.

Heh my serial number is very close to yours. How did you go about getting a replacement in case I have to go that route? Thanks.

What I did was: Contact Dell's Support by phone, explain the problem and do some additional checks confirming the issue. A service order was created and 2 days later a new unit arrived for replacement.

Chris is particularly interested in the serial numbers. Would be a good idea if you also share yours.

Thank you, I'll call them.

I have the same problem with U2718Q when it's connected to TB16 USB 3.0 port or directly to XPS 15 9560. Is RMA the only solution?

I have the exact same problem.  I'll all the things that you suggest and didn't work.  My serial number is

CN-04K8X7- QDC00-7B1-ORCL-A01

sebastien00,

Same revision (A01) built on November 1, 2017. As thcoura did, get it exchanged. If the replacement works, post the serial number and A0x revision.
