Average Life of MacBook Battery?
What will happen is that before the battery runs completely out, and I am on battery power, the computer will just turn off and shut down completely. There's no telling when. The most recent time was when the battery indicator still said there was a 85% charge on it. The time before that it got down to 90% before it did the same thing.
Seeing as how my MacBook (which I love) is 3-4 years old, I'm thinking it's time for a new battery. Any other thoughts?
MacBook, Mac OS X (10.4.11)
