Hey, everyone. My Macbook 15" it stopped charging at all last week, but the charger’s light stays green. Before the issue started, it was blinking green, but now stays solid. The Macbook won’t work even when plugged in, leading me to believe that it was a problem with the port, which looked worn out and even damaged (ground on one side blackened and melted). I thought that replacing the port might do the trick, so I did ordering from iFixit and following the correct tutorial, but I’m continuing to have the same issue. I also now hear a faint buzzing sound from the magsafe/port while it is plugged in. Update (07/30/2016) Sorry, Dan! I’ve never posted on here and I guess it shows. Here’s what I came up with MacBook Pro “Core i7” 2.6 15" Mid-2012 2.6 GHz Core i7 (I7-3720QM) RAM 8 GBStorage 750 GB Update (08/02/2016 Hey everyone, I dropped it off today to get diagnostics done on it and was told that the logic board on it is fried. Thank you everyone for your help!
Just so we’re on the same page here you followed this IFIXIT guide: MacBook Pro 15" Unibody Mid 2012 MagSafe DC-In Board Replacement and used this part: MacBook Pro Unibody 13" and 15" MagSafe DC-In Board Correct? For now don’t use the power adapter! What is the status of your MagSafe charger’s cord? Is it damaged in any way? If it is you’ll need to replace the adapter as that likely damaged your DC-In board and it could have also damaged your systems logic board. Pressing on the Battery checker button on the left side are you able to see any LED’s If not you’ll likely need a new battery as well here. I would visit an Apple Store and have them service the system as this might be covered under warranty depending on when you bought your system if the MagSafe charger cord is not damaged.
Try a different charger.
