My macbook turns off when unpluged

[Adroan]

MAC OS X 10.6.
I have had my macbook for about 2 years now and it has been causing me issues lately. I am getting ready to deploy and need to figure out what is going on with it. I have tried resetting the entire computer and that did not work. I tried alot of different resetting the battery things but nothing worked. Just let me know if there is anything I can do thank you so much.

I think you need a new battery.

I concur.

2 years of moderate use is about as long as those batteries last before needing replacement.

Especially if you leave your Mac plugged in all of the time. It's tough on the battery. If you have AppleCare, check that out, or take it to the "Genius". My battery was "swollen" after about the same time and they replaced it. Good luck over there...
