I'm having in issue with my 13 " macbook (Late 2008). It's not charging! When I plug my adapter in, the little charging indicator is a faint green, not the bright green it usually is. It does show on my computer that the adapter is connected, but it's not charging. I recently reformatted my whole computer (started from scratch). Also, I was having battery issues a few months back and got the battery replaced, so I don't think it's a battery issue. I also reset the PRAM and checked my adapter and port for dirt and such, but it's pretty clean. Is there any other suggestions on what I can do, or what can be done?
