The external display stays on. It looks as if power management were kicking in by error but affecting only the internal display. When I’m working with the external display, I need to move the mouse into the area managed by the internal display to wake it up again; else it seems to remain black (though I haven’t tested that behavior thoroughly). Most tests with the external display were made with the port replicator and an external display plugged into one of the DP ports via a DP–DVI adapter. I cannot tell for sure what the behavior is with the external display plugged directly into the laptop. 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.
