Problem with Macbook Battery

[dansmith3003]

Hi i have a macbook bought in July 2007, it has been working fine since then but recently there has been a problem. The computer refuses to start when the power supply isn't present, even when the battery is fully charged (as indicated by both the computer and by the light system on the battery). The computer is fine when the power-cord is present. Could anybody possibly diagnose the problem and any possible solutions.

Thanks in advance

if you plug the cord, start the laptop and then remove the cord, will it turn off? if yes, it sure is the battery. you should try your battery in another macbook, or try another battery in yours.

I don't know if it would help in this case, but a utility you could try for possible troubleshooting on the battery is CoconutBattery.
