I'm just about throwing my new Dell laptop (Precision 5520) out of the window!

When I disconnect laptop from the thunderbolt dock (TB16), the laptop screen stays off until it's connected back to the dock. No matter if I put the laptop to sleep before disconnecting. Everything works just fine if I shutdown the machine and restart it without connecting to dock.

The best part is that the computer seems to be running normally, the screen is just black.

Anyone got a solution in mind? I'm running Windows 10 and I have installed all the possible updates.
