Solved the issue. turns out PSU was having hissyfit whenever the battery was at full. Keeping the battery partially drained fixes the problem

The game is indeed using the NVidia GPU; I specifically manually set the program to use it. I have tried both reverting drivers and finding the most up to date ones; neither seems to have an effect. The logs appear no different from the previously functional startups, and do not appear for all of the shutdown times. The more recent is from a shutdown event, the earlier one is from a fully functional run. clientlog_Wed_Feb_15_19-49-22_2017.txt clientlog_Wed_Feb_08_16-08-17_2017.txt

I should preface this by saying that the program was functioning quite normally up until approximately 3 days ago. Without any change that I could detect, starting avorion causes the numlock and capslock keys to begin flashing, along with a regular 1 second pulse beep, after which the computer will automatically shutdown. No BSOD or anything of the sort. Temperatures do not even come close to TJMax; highest I saw was around 60 degrees C. Memory usage was also low, only a few GB above standard system usage. Disk usage was around 40-50%. I have done a thorough cleaning of the laptop itself with compressed air, and the problem persists. CPU usage was likewise low, only running at about 3.2GHz.

Any advice as to how I should move forward?
