Welcome to the Apple Commun city where some of us do our best to help each other.

Apple has a support an article (link below) that may provide some answers.

Hope this helps

You can use the link in the upper right corner of this page to initiate a service ticket. I'd suggest you do this relatively soon before your battery may start swelling.
