got curious of whats inside this 5 pins mac adapter, thats why im here. your blog showed on my google search. my sister's nasty mac is now having a hard time charging. i just removed the plastic cover of the 5 pins which was somewhat a bit melted. i also checked the pins one by one and i noticed that some of them loses the springy thing when pressed. i had one to be pulled by a long nose pliers because it got stuck when i pushed it in. and now whenever i try to connect it to the laptop it is just gonna need some pushing and just trying to get the green light indicator then orange. so yeah, the 5 pins are just the culprit. this is just my fix for the mac book pro. in youtube theres this two other fix that i might do if ever the situation got worse. opening the square charger (whis is hard btw), i was trying to open it because the wire near there are broken. but good thing though that i was still able to connect the wires there without opening (nice luck). the other fix is the one that you need to resolder the wires inside the 5 pins. i didnt go that far because i fixed my problem right at the 5 pins area. and the fact that it was hard also to pull the thing out(managed to pull the one with magnet but i broke the one connector plus i dont have tools). the youtube guy uses vice grip while i used nose pliers. using cutter(blade) to trace the connection also helped in loosening abit of the tightness of the magnet. and also the inside plastic (the one that holds the inside part was somewhat beginning to be destroyed if i continued getting it out so i just stopped. tested the laptop then it worked, after the pressing and nudging. well i didnt actually thought that the inside part was really needed to be resolder because it was located in a safe hard place. the tutorials says that overtime the wires loses the solder because of heat but i thought otherwise. IT WAS THE 5 PINS
