my macbook pro completely shutsdown when i take the power cord out and the battery has a full charge. if i try to turn it on, it turns on for a split second then dies. put in the power cord and works fine. ive done all the troubleshooting procedures such as reset pmu and pram etc. i rang applecare and they gave me a service no. and im going to take it to the apple store tomorrow. also when i wake it from a long sleep i get a electric buzz sound which dissappears after a while. and thoughts? thanks

IMO, the best you can do is to take it to the Apple store and let them take a look at it. It sounds more a hardware problem than a software in which case you cannot solve alone. Sorry to hear all the trouble.

Im hearing that same electric buzz sound you hear after a long sleep. Interesting to know what that could be.

Hey,

Yeah, I had a similar problem. I suddenly found the laptop wouldn't run off anything but the power cord. When it goes to run off the battery, it will do so for about 1.5 seconds, then totally die (like you had just yanked out the power cable without the battery).

I don't know about the buzzing sound, but it looks like it could be your battery. Apple simply replaced mine in 2 days via post, and it worked perfectly. Weird thing was, the battery was one that Apple had allready sent out to replace my original one due to their battery swap out scheme, which was a safety measure I think.

Anyway, fingers crossed it's only the battery
