my tablet do not show it charging after connected to charger

Solution
Take the back off and see if the battery is easily removeable. Some tablets make it difficult by sticking the battery down with strong glue and soldering the wires to the board but if you can take it out, do so. See if powering up on mains electricity works any better.
