If you have access to another charger, of the same specs, then I would try that one on the device to see if it is the battery or the charger that is a problem. If you don't have one, then it will need to be looked at by a professional. Also, while many laptops batteries are hard to get to, they are still accessible. At least if you feel comfortable trying to yourself, or if not, then if under warranty I would contact the manufacturer. If not under warranty you may want to try a local tech.
