what lies!!! batteries arent cheap are they!
I lie to you not. The representative stuck a USB key in the port that had a program on it that tested the battery specifically. He booted up the system via the Option button (aka. the boot camp screen) and selected the USB drive. The results of the test indicated in big bold red letters BAD BATTERY. I saw him do the test in front of me.
You unfortunately cannot calibrate the battery because calibration requires allowing the mbp to go to sleep after it displays "Warning, battery is low". With this problem at hand, the computer automatically shuts down at random power levels and won't start up without a power cord. Pressing the battery button at the back of the mbp shows a flashing single green light.
I have tried calibrating it by putting the computer to sleep manually at approximately 50% battery life (mine would shut down at around 46%) and leaving it alone for over 24 hours. It does not calibrate, I urge you to not waste your time.
