I have a 2009 MacBook Air (MacBookAir2,1)
I have a compatible MagSafe and a Apple one.
Sometimes (almost most of the time), when the computer is running and not in sleep, if I plug the MagSafe, it goes orange for a few minutes then goes back to green. It says that the computer doesn't use battery but it doesn't charge it.
I have tried with both chargers and it is the same.
Now I have also tried to shut the computer down and charge it : it works, it remains orange and charges the battery.
I must admit that I have changed the battery to a compatible one because mine was too old.
Do you think the fact that it is a compatible battery makes the computer thinks it is fully loaded and stops charging ? Is there a way to prevent that instead of stopping the computer to charge ?
