Hi,

I have a new laptop which is connected to a dock by USB type C. The dock has 2 external screens connected to it and the laptop screen closed.

When I disconnect the laptop from the dock, the session is killed before the PC going to sleep. On the contrary, when I use the PC on its screen, the session is just suspended when I close the screen and reactivated if I connect to the dock.

I havn't found any configuration setting related to that and no clue on the Web. Any idea ?

P.S.: I forgot to give information about my hardware and software. DELL Latitude 5590 + dock DELL WD 19 + up to date Neon User Edition

Check the system settings, is the laptop also powered through the dock? That might give a clue...
