It sounds like either the battery won't hold a charge, or the charger won't charge the battery. Either one could be the culprit, so it's up to you which one you want to try replacing. Generally, replacement chargers are slightly cheaper than replacement batteries. It could also be that the power jack on the system board has gone bad, but the battery and charger are both more likely (and easier) solutions.
