I also have some additional information that may help to narrow down the cause of the error: If the VLC media player is running in the background, which prevents the power-down states, the computer can be woken up again by moving the mouse, even after a long time. However, the internal display then goes dark after a brief ‘flicker’. A similar state is achieved if you wait 5 minutes after dimming the internal display and do not move the mouse immediately. In this case, the internal display only returns to normal brightness when a key (brighter/darker) is pressed on the keyboard. The external display connected via HDMI works perfectly.
