2018-02-10 16:25:35 Michael von Glasow description Occasionally, the internal laptop display goes black for a few seconds, then comes back to life. 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.

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.
