XPS 13 9300 - Thunderbolt 3 issues?

Hi there,

I do not currently own an XPS 13 9300 (I have ordered but it will only be delivered to me next week..!) but I have come across a couple of threads on the Dell reddit forum where Thunderbolt 3 on eGPUs and monitors does not seem to work properly on the 9300 at the current moment:

https://www.reddit.com/r/Dell/comments/fb3k1j/dell_xps_13_9300_i71065g7_1tb_gb_thunderbolt_3/ -- TB3 not working on eGPU, as well as LG 34W95K TB3 monitor (unless the laptop is separately powered up through the other TB3 port by the supplied charger)

 

https://www.reddit.com/r/Dell/comments/fbkzzd/my_xps_9300_story_so_far_spoilers_it_needs_a_new/ -- eGPU not working on the TB3 port

 

https://www.reddit.com/r/Dell/comments/fd9o2z/dell_xps_9300_external_monitor_issue/ -- LG 34W95K TB3 monitor not working (unless the laptop is separately powered up through the other TB3 port by the supplied charger)

 

Based on the above reports (which seem consistent and suggest a firmware issue), it seems as though the XPS 13 has some issues powering up certain TB3 devices at the current moment.

 

Can Dell kindly look into this and see if this is solvable with an BIOS update? Thank you.

Thunderbolt security would need to be set to NONE.

Secure Boot would need to be set to OFF.

GV-RX580IXEB-8GD works fine on my Dell.

Thanks! Just to clarify--you are using XPS 13 9300 as well?

May I check -- do you need to wire separately another power cable to the laptop? Or it can power up just fine through the eGPU's power brick?

I have the exact same problem. My monitor LG34wk95u wouldn't connect unless I plug in the charger. That is a shame for a laptop like this.

@jovaseq that was what I was worried about! Have you contacted dell about this? Just curious.

To be honest, no. But I wanted to check with other users first. I am thinking of returning it back...

@describee Dell told me that this is how the laptop works. It needs power in order to run smoothly.

My monitor LG34wk95u wouldn't connect unless I plug in the charger.

And how is that a problem when the monitor is anchored to the desk anyway?

Sounds like the little XPS-13 just wants some power. 😀

Well it's a waste of a perfectly good port, for one. And the monitor is supposed to power the laptop in the first place with PD pass through.
