White MacBook battery problem

[iPhone 3.0!!!]

my macbook is only about 10 months old but my battery just started refusing to charge. the light on my magsafe lights green but the lights on the battery don't light. the battery icon in the status bar says (not charging). The battery says 0% and if i unplug the charger it dies instantly. do i need a new battery or is there something i can do?

If your battery has less than 300 charge cycles and less than one year old, take it to the apple store for replacement under warranty.

Do not leave the macbook in sleep mode for extended periods, this can kill the battery.
