My son discharge battery fully untill tablet turn himself off , after that any attempts to charge and turn on was failed , i tried with charger and on pc usb no indication of charging. Because i have too the same tablet im sure there no problems with chargers or cables both are original come with devices and they charge my tablet. I found that tablet is charge only when i put it in docking station. I waited till baterry comes to 100% after that problems with charge directly from adapter still continue . I made hard reset , flashed last twrp recovery after all flashed the whole rom - still no charging . I'm in death end.
