    The motherboard manual might have a section that explains what the bleeps mean.

    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    For your i7-7820HK processor, I would run turbostat in some terminal always, suggest this, or similar, command:

    Code:
    $ sudo turbostat --Summary --quiet --show Busy%,Bzy_MHz,IRQ,PkgWatt,PkgTmp,RAMWatt,GFXWatt --interval 6
    For the comment about it being 50 degrees please be aware that processor package temperature can change extremely fast. I have measured (oh darn I can't find it now) over 100 degrees per second. I am saying it is easy to miss a thermal event entirely if only casually observing temperatures. As a test try disabling turbo in BIOS. This will keep temperatures lower and timing margins wider, and is perhaps why you got further on battery sometimes.
    Any follow-up information on your issue would be appreciated. Please have the courtesy to report back.

    While my daughter was using my wife's System76 laptop today, I heard it beep (loud beep). I had never heard it beep before; however, she explained it was triggered by a low battery. Sounded reasonable to me.
