Good Afternoon all, something strange has been happening to my SP3 recently. I have it charging all night and unplug in the morning to take it work, but upon unplugging I hear the fan come on, the screen is on and my tablet is warm to the touch. I look at the battery level and it's down to 77%! A 23% battery drain within an hour of getting to work from the time I unplug it! I did a full system virus scan and found nothing so what could be causing the issue?
