This happens, when I close the lid, or press the power button, to put my laptop to sleep. It just shuts down. Sometimes it works, but I couldn't identify the circumstances.
Here is what I've tried so far:
I checked the event viewer, but there were no logs about this shutdown, just an error, that it was unexpected.
Here the laptop: Dell XPS 15 9550 | Memory: 16 GB DDR4| Processor: Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz[Cores 4] [Logical/Core 2] | Operating System: Microsoft Windows 10 Home
Thanks for hte help!
