You need to have the battery replaced. It has malfunctioned. Please disconnect the AC charger and turn off the computer. Make an appointment at the Apple Genius Bar for service after the stores re-open. If you need to find an Apple Store - Find a Store - Apple. Also, see How to find your nearest Apple Authorized Service Provider (AASP) or Distributor (AAD).

If the battery is user-replaceable, then visit OWC to see if they have a replacement battery for your model.
