Check the battery for swelling or a connection problem . [https://www.youtube.com/watch?v=9XMtaC57LiQ|Use this guide] to open the device and if necessary replace the battery . I would start by reseating the battery connector if there is no visible swelling of the battery. Just unplug the battery and then reinstall the plug. This often helps these tablets. If this brings no joy then you should also check the charger port for defects like broken solder joints or a loose port .

Hope this helps
