Hey guys,
I have been having an issue where my macbook randomly shuts down, it makes the same sound as when you force a shutdown by holding the power button. A "bip" and everything goes black. This only happens when running battery, and it can happen at 40-95% battery life, most often at about 40-50 %.

I have been surfing the net, and finding lots of people with the same problem. However there solutions haven't worked for me. I have tried recalibrating the battery, heck I even bought a new battery and calibrated that too. My software is ofc. up to date. Everything is running at decent speeds and not getting to hot.
The only thing I can possibly think of, is that it may be an issue with my power cord. Sadly I do not have access to another one, so I can not test if that would solve it.

(Im planning to buy the 2012 imac, and maybe the 2012 mbp or air - and so I wanna save my money and not spend 185 bucks on a power cord that might not work)

Anyone got any ideas,

Thanks in advance


EDIT: My 3 week old battery now says: Service battery and that it takes roughly 20 hrs to charge :S
