I have the same issue. I get it while playing Elite: Dangerous (for which I use a HOTAS) as well as when I play Blade and Soul. I also get it while watching videos with VLC or talking to my friends with discord. Sometimes I walk around the apartment while talking to them and the auto shutdown starts to initiate. The reason I got a wireless headset was partially for this flexibility. Hope you guys fix this soon :D
edit: My system specs are in my profile.
