According to their forum, you have to uninstall all antivirus software, disable windows defender, and turn the display brightness down when the battery gets lower. Also, it seems you can’t run a lot of power from the tablet once it hits the lower end.
Based on this my guess is something to do with the quality of the battery. If this was a premature failsafe it wouldn’t make the pop. I talked to my brother who knows more about this than I do(taken classes on circuitry). If it is coming through the speakers, he recommended trying to disable the audio in device manager in windows to see if it is the audio chip. He thinks it is one of the processors in the system pulling too much on the battery. When a battery gets low, the resistance goes up, making it harder to maintain voltage. Normal batteries have many cells to keep the voltage up, and just loose amps. He said if the display dimming helps, that means it is better able to maintain the voltage at the low end of the battery. This is all a result of a low-end battery according to him.
