Older Macbook Air suddenly dies saying no battery even though it has enough
It's been happening for a while now. I'm running on battery, maybe anywhere under 70%. I turn my macbook on from sleep, then it runs for less than a minute then suddenly dies. When i try to start it again it says no battery. I plug it in, it starts, and it shows... whatever, 67% battery or wherever it was before.
Halp?! :)
