The battery on my new 12" powerbook does not always charge. When I first got it, it had the same problem. It was fine for a month, but now has the same problem again.
The LED on the side of AC plug is always green, even though the battery is totally flat. (It's supposed to turn orange and then start charging.) When plugged into AC - the battery monitor in the top right corner always reads 'calculating...', but never calculates how much time is left on the battery.
I'm hoping there is simple solution because I'm in Egypt and have no way of taking advantage of the warranty.
