I'm having the same issue on Mint 19.3.
Just installed mint a couple days ago.
Laptop is docked with 1 external monitor attached. The laptop screen
goes black for a few seconds at a time. External monitor stays active,
and I can use the external monitor as usual during the blackout. The
black laptop screen come back to life on its own, and all is back to
normal.
Happens every few hours.

Title:
Intermittent black screen on HP EliteBook 840 G1
Status in xorg package in Ubuntu:
Confirmed
Bug description:
Once every couple hours, the internal laptop display goes black for a
few seconds.
This was reproducible:
+ With the laptop connected to a port replicator and the external display
connected into the port replicator DP port via DP-DVI adapter. The external
display remains on during this time.
+ With the laptop not connected into a port replicator but connected to an
external display. The external display remains on during this time.
+ With the laptop not connected to either a port replicator or an external
display.
The hard disk was originally installed with Ubuntu MATE 14.10 in a HP
EliteBook 6930p, upgraded to 15.04, 15.10 and eventually 16.04 and
finally moved to the EliteBook 840 G1. The problem started immediately
after the drive move.
