Mac Book Pro Battery Not Charging

Question

I have a 2.2 Ghz 17' MBP running snow leopard. My battery is refusing to charge. While on standby power the battery seems to charge to 100%. but when in use appears to discharge quickly even with the mag safe attached. Mag safe lights show green then orange as the battery discharges and the battery icon shows the mains connector and the words (not charging) next to it. The icon rollover shows "Battery is not charging. Power Source : Power adapter". The battery info in profiler is below.
