Very weird. I detached the awake laptop from my docking station, then i worked with it without attached power supply. I watched something without using my laptop. My laptop turned into standby. Then I woke it up and the screen was just black, but the power LED indicated a awake laptop. Only a forced shutdown by pressing the power button until ended this bug.
