My daughters amazon tablet was completely dead. Kept it on charge all night/day,kept checking but nothing just battery symbol in center
THEN I removed back (YOUTUBE!) Carefully unplugged/pulled small component where battery wire's are attached,Black thing, then Reattached,just pushed it on then replaced yellow tape! Hey presto it works 👍 phew. Just don't charge as fast. BUT it's still works so happy little lady.
