Why won't my mac-book accept a cherge
My Mac-book Model A1286 will not accept a charge. I used a tested good charger on another mac-book and it works well. I then attached the same good charger to my 17" mac and nothing happened. the indicator light on the charger connector did not illuminate, The mac-book will not turn on. The battery test light on the side is flashing on the last light with or without the charger. I cleaned the connection point with a plastic toothbrush and try for a better connection and nothing. I saw no form of corrosion or damage in the area. I think it may be the mag-safe DC in board. Any help would be appreciated.
