please tell me about how I can do ? ,if my battery charger of macbook isn't work.
Morning, when you start charging your MB's battery, will the charger be hot after some time? If everything works ok, the charger will be hot or warm. There is also a small led light on the socket which is connected to mac book. The light is orange when the charger is working and green when the battery is fully charged.
Also you should check if the battery is still in a good condition. My MB is four years old and I had to buy a new battery some ago because the old one was totally flat.
