The charger light on my Macbook flashes orange/green when fully charged. It goes to 100% then it turns green. A few seconds later the light turns to orange again. And it keeps going on like this ... I tried shutting it down, updating, removing the battery. What should I do? I think this is a software issue of some sort because problems started appearing with the 10.4.10 update: unable to wake up from sleep, screen flashes. Fortunately it doesn't do those things any more, but this charger problem is really annoying. Edit: Also tried resetting the SMC, but it didn't work.
