I have macbook pro 13" early 2013 and it comes with 60w magsafe 2 power adapter. I was working normally all the time and a week ago it started to act weirdly. The green light is always on, even if its not plugged into mac and it doesn’t charge the battery, only holds the power. At first I though its my pc problem, did SMC reset but still nothing. Tried with my girlfriend pc, its the same. Its not charging at all only holds the power. Does anyone got the same problem and what should I do with charger? https://discussions.apple.com/servlet/Ji… Update (10/18/2015) https://www.dropbox.com/s/e39s5ccw3wl4xx… Thats the results I am getting, not sure if the picture was uploaded correctly..
Download and run Coconut Battery to get a better idea of what is actually going on and let us know your results. Any watt adapter will work, but the higher wattage ones will charge faster. http://www.coconut-flavour.com UPDATE Coconut says it is discharging, was the MagSafe plugged in when you ran it?
Better late than never, here is a correct answer. (I hope.) Your MagSafe power supply’s identification chip has fried, or MagSafe plug is otherwise damaged. Inside every Apple MagSafe tip/plug/outlet is a microchip which does two things: it IDs itself (as 45W/60W/85W/Airline and serial number) and controls red/green LEDs. Your MagSafe plug is damaged: maybe its chip is fried/zapped, maybe cracked from severe traumatic impact (not very likely), maybe damaged by liquid intrusion. I can believe in a short circuit: maybe minerals dried in a conductive path to LED, so that is why it is always illuminated. What to do? Keep your “power brick” AC adapter, get a replacement MagSafe plug or cable assembly, and splice it on. If you cannot find a used Original Apple MagSafe tip, then a non-authorised replica is acceptable. One will be better-off with a counterfeit tip spliced onto genuine power supply, than a knock-off power supply. very similar problem, cross reference: Re: “Battery is not charging” and no light
