I've searched a lot on this problem, on Google and other forums and although I can find plenty of people who've had the same problem, I can't find a solution other than taking it back to the Apple Store for a replacement. Which is something I can't do as my Warranty has ran out. So before I just buy a new battery, I want to make sure there's no way I can fix this. Basically the problem is that my battery is empty and won't charge, I always have to run off the Power Adapter. It happened in some strange circumstances though. A few weeks ago my power adapter sort of broke on itself, it would cut out all the time, I thought it was the fuse which it turned out not to be. Eventually it just died and I bought a new one, and upon plugging the new one in, I get the "Not Charging" status in the corner. My Macbook was bought in Nov 2006 but I've had a new battery since then, I can't check the proper stats of it right now as I'm at work but I think I remember seeing that it had done around 650 cycles on iStat. Coconut Battery crashes when I try to check. Any responses would be appreciated.
