Macbook Pro battery is not charging but the battery meter is full

Hi guys!

I have a 19 months macbook pro. I've tried using 2 different AC adapter but my mac's battery is still at 0% and the status says "Battery is not charging". I think my battery is dead but the LED battery indicator on my battery shows 5 lights, means its at full power.

I've tried to disconnect the AC cable and remove the battery, then press the power button for 10 sec but nothing change when i start my mac again...i also tried to reset my PRAM ( i think ) by holding a cmd opt+PR while rebooting but it didn't help to solve the problem too. I also have the battery update 1.2 installed on my mac and the results is still the same.

This is my battery info from system profiler. I hope someone can tell me what to do before I visit the Apple store.
