I have exactly the same problem.
Here the info you need:
System Sleep Timer (Minutes): 0
Disk Sleep Timer (Minutes): 0
Display Sleep Timer (Minutes): 0
Wake On AC Change: No
Wake On Clamshell Open: Yes
Display Sleep Uses Dim: Yes
Reduce Brightness: Yes
Extra info: Green light on the charger is off. But when I plug in the charger, the latptop knows and increase the brightness. I have two batteries and the problem is identical with both. I checked the SMC firmware and I have installed the latest.
Thank you for your help. Here the info you asked for.
Note: Today I un-plugged and plugged several times. I got the green light for less than a second, then quickly changed to orange for another second and then is off. There is no light on magsafe. BUT the icon on the screen says charging. Crazy... everday different behaviour...

I do have the same problem. The light goes off if I move the wire, but it does charge. Are you sure that it doesn't charge?
Plug it out again and put it back in and check that the light would be on.
Sorry, I didn't read your replies.
Yeah, it is a different problem. How old is your battery ? Even 5 years old battery should work well and hold at least 3 hours of charge. Maybe it's the issue with the magic safe?
First of all, thanks both for your comments.
Indeed today is charging, but the light keeps of, not orange or green. If the light were the unique problem I woudnt mind. But yesterday for example it didnt charge at all. I dont know why today it decided to recharge the battery, that by the way, is about 3 years old.
I double check the magnets, I also checked the version number of my SMC software, and everything looks fine.
