i remember a similar issue for desktop computers from ~15 years ago, and a keyboard with a helpful shutdown button. i think it was located a bit to the right of F12. from memory windows just started shutting down and there wasn't a way to interrupt it. pretty funny. not something you'd hit often, but possible to hammer accidentally if playing a full screen game that used a bunch of F1-F12 keys.

after hitting this a few times while playing games i levered all of those extra helpful keys out.
