Battery is not charging

I have a ZD8350LA ,some days ago the battery stopped charging and the indicator led blinks every time the battery is in the device, my computer is only 10 months old, can it be a configuration problem on the motherboard? or the battery has broke down? My Li-ION battery stopped charging out of the blue. The AC adapter definitely works, because I can use the computer when the AC is plugged in, the battery doesn't seem hold a charge anymore at all. It used to work, and it didn't stop working gradually, just all of a sudden.
