Mac book Pro 15" (2012) Battery life when reduced to about 50% charge left, the MBP blacks out and has to be plugged in to restart. After restarting still shows 49% left, then suddenly goes down to 8%warnig about an impending turning off, then without warnig goes back to 43% charge and keeps on.
What is the problem?
