I didn't want to start a new thread, but I am having a similar issue..
MacBook says (Not Charging) but power source: power adapter, green light is on, on the Magsafe. It looks like it's running off the power source but not battery? Coconut says charged plugged in, not charging and it's at 95% full.
Cycles: 27
MB is 5 months old.
Suggestions? Should I reset the PRAM or whatever? Sigh, it was working well last night, not sure what happened this morning. I checked the magsafe, the cord looks fine and intact.
