Hi guys I have a MacBook Pro Retina 15" Late 2013 (I think) .. one day whilst connecting the Magsafe 2 Charger there was a little bit of static spark around the port and from that point on it wouldn't detect the charger, i.e no lights at all on the charger. I bought a new charger and verified it works on a friend's machine. So I then replaced the Magsafe 2 Charge Port, still nothing. Any ideas what to look at next ? Any advice would be greatly appreciated.
