Tablet won’t turn on
Battery won’t charge or hold charge
Check to see if you are getting a light from the device screen or the charging port. If you are not seeing a light that means you are not getting any power from the cable or wall. Check the cable from the wall to device and be sure it is sturdy and properly plugged in. If the connections are proper then your issue is most likely within the cable and will need a replacement cable.
If you are not sure if the issue is your battery, make sure the device can power on and run while being plugged in. If the device runs but turns off the second it is unplugged or does not turn on at all, then you may need a new battery. Here is how you can replace the battery yourself “Using this Guide”
