Dell XPS 13 7390 usb port stopped working

Thank you! We have received the required details. We will work towards a resolution via private messages to ensure the security of your information. In the meanwhile, you may receive assistance or suggestions from the community members as well.

It looks like a hardware issue with the thunderbolt port.  If the system is less than 30 days from shipment, your best course of action is to contact Dell to have the system replaced under your 30 day satisfaction guarantee.  If it's older than that, contact Dell to have the mainboard replaced under warranty.

I'm glad that the system is working.

Please observe your system and let us know if any further concern. 

I've had this PC since March and this happens to me about every other week.  I'm about done with this PC and am strongly regretting my switch to Windows OS after a decade with Apple.  Really want to return this computer because it's far more trouble than it's worth.  If anyone comes up with a permanent solution, please respond because I frequently lose USB connectivity which greatly interferes with my work from home constraints.

I have the same exact problem with XPS 7390.. tried all solutions mentioned above, none worked!
Someone please help!

Couldn't agree more. Some toys are more durable and reliable than this machine. Not worth its price AT ALL!! Very disappointed

same here, very disappointed with this machine and dell support in general .

Too bad that those XPS are supposedly the high end series and yet contain so much problems and instabilities . Those are around 1,500 - 2,000 $ machine ! 

I have XPS 13 7390 since December 2019 and have not spend a week without having an issue where I would like to throw it by the window. 

Here are some of my recurring problems:

- enormous power drain overnight 

- sleep mode are erratic ( and seem to cause problem above) 

- tend to overheat ( have to undervolt CPU )

- poor wifi speed

- recurring problem with USB3 thunderbolt

- fingerprint logon does work once in a while

- probably more that I can remember here.

I have probably fixed most my self  with solutions found on internet and had to edit many times the registry to get some very important features back 

And the worst for me, is that never a DELL engineer has provided a correct solution in any case , they would just ask for service tag, reboot, re install  and that s it . Not willing to understand the underlying problem or escalate to higher level to fix it in future release . They will just keep selling this fancy half-broken XPS to the next naïve customer .

well , this is not a solution ! Does DELL consider it as a fix for real ?

@DELL-Cares I have the same issue. Is there any working solutions for this now?

Mine had the same issue, Dell replaced motherboard under warranty. That fixed the problem.

I have this problem currently too - XPS 13 7390. Suddenly the USB port stopped working. I have tried all the support options and have had @DELL-(doesn't)Care on the line but just like you guys the support was generic and pretty useless. 

I hope someone stumbles across a fix soon. Unfortunately, my device is just over a year old so out of warranty. 

It is such a shame to have done so much research about which laptop to buy, decided on DELL and then have such a bad experience across the board - from delivery to repetitive technical issues to their appalling support. 

I had the same issue. 

I explored all the available ideas that I read online. The one that worked with me is to switch the laptop off, remove the battery, press the power button for 30 seconds, and switch it on again.

This fixed my issue.
