I was sitting at my desk running word and safari while my mac was plugged in to the official apple charger. It was charged to 80% when it randomly shut off while I was typing a sentence in word. It is now unresponsive, will not turn on at all even when an SMC reset is attempted. The genius bar technician was stumped, he said it has nothing to do with the battery and might be a issue with the motherboard, but I haven’t had any previous issues. No water damage, never dropped, and it was recently updated to big sur. It was totally random as it was running fine one second and powerless the next.
