Mac BookPro shut downs if it not connected to power.

[rjclue99]

my mac book pro works and worked fine for two years. now all of a sudden it shut-downs automatically and quick. bang! its gone. i couldn't turn it on. I, when connected the power cable it turns on and work fine as ever. if you take the power cable off its gone in a flick of a second. i removed the battery, wiped it and pressed the button below the battery, it says it has full charge. do u think its the battery problem??????? help me pls.😱

Yes, in all likelihood it's a battery problem. If you have AppleCare, the replacement should be covered by warranty.

Could be the battery or could be the power board. Either way, try an SMC/PRAM reset (that is Apple's first line of defense in power issues).

That behavior is what happens when the battery goes bad, so you probably need a new one. What does it say about your battery health in coconutBattery?
