I'm a member of a volunteer search and rescue team. We have Surface tablets in all our vehicles for maps and getting assignments. I recently installed a Surface 3 into a vehicle. When the car is started the usb power supply starts powering the tablet. When this happens the tablet turns on. Is there a way to turn this off ? Since the people using the car didn't turn the tablet on, they rarely remember to turn it off leading to the tablet being always out of battery. I've googled a bit but haven't found anything about this. checked the bios but there aren't any settings for this.
