My tablet isn't charging. I put the charger in and it won't go all the way in. It's wiggly and I put tape on it to make it go in, but it's still loose. My battery is dead and has been for about a week. I need to charge it but it won't charge or turn on. I hold the charger in and push the power button but it doesn't come on. What can I do? Is there something wrong with the charger port or the charger? Help please!!
