Laptop (XPS 15 7590) is randomly going to sleep/shutting down while on dock

I have new Dell XPS 15 7590. I got a Dell dock WD19TB which I was using for some time. Suddenly today I started to experience strange problem. When I connect my laptop to dock, after few minutes it would go to sleep. When I then press the power button to wake it up it wakes only for few seconds and then goes to sleep again. So basically I can not use it at all while connected to dock.

Do you please have any idea what might be wrong and how to fix it?

Thank you

Matus

Re: Laptop is randomly going to sleep/shutting down while on dock

update:
I first thought it is a problem with a dock but ruled it out by having connected macbook without any problem for over an hour.

Then I thought it is due to drivers but I used Dell Update and checked that everything is up to date.

I also tried running other system (ubuntu) and same problem is there.

It looks like it is a problem with laptop itself.

Hi, 

I was experiencing the same problem, with the same hardware (XPS 7590 and WD19TB) after the latest BIOS update.

I was able to fix it by going into BIOS -> thunderbolt adapter configuration -> choose "security level - no security ".

Hope it helps.

I am having the same issues with my XPS 9500, I know it's different, but I am going to see if that can fix the problem anyway.
