But no, the AC adapter MagSafe light kept off. Changing this connector is possible, but it is a pain.ДЄfter the corrosion cleanup, I thought the job was done. But do not expect to have something clean at the end, gold is gone. I used a 0.7В mm flat screwdriver + flux off to remove most of the corrosion.

The first thing is to carefully clean this connector. The first obvious culprit was the connector: just look at the corrosion! Corroded pins on the left I/O board connector

This small board has the MagSafe connector, a USB connector, and an audio jack connector.Д«etween the motherboard and the I/O board, there is a flat ribbon cable (it is a shielded multi-layer FPC, no a straight simple cable that connects pin 1 of the motherboard connector to pin 1 of the I/O board). Mainboard on the left, I/O board on the right, flat ribbon cable connectors in between.ДЄ1466 MacBook Air has a mainboard, and a small daughter board called вЂњLeft I/O boardвЂќ by Apple. Tiny, isnвЂ™t it?ДЄ good iron solder, flux, tiny 0.3В mm tin solder, solder wick, tweezers, flux-off (I really like the Chemtronics one, but if youвЂ™re comfortable with pure isopropyl alcohol, keep it). This is the size of component youвЂ™re going to look at. Images below are VLC screenshots of this kind of hardware. Your eyes wonвЂ™t be really useful with 0.35В mm pitch component and 0.1В mm PCB tracks. Fix a A1466 MacBook Air charging circuit. In this situation, if you are the only electronic engineer in the company, there is a very high chance that your colleague asks you to look at the problem. (If you know a good waterproof backpack, tell us!) This happened after water damage on a rainy day: the computer was in a colleagueвЂ™s backpack, and the rain was strong enough to wet everything inside, including the computer.ДЄfter letting the MacBook dry up during the night, it is not charging anymore. The battery is slowly dyingвЂ¦ just a few percent remaining.

When the AC adapter is attached, you can boot the MacBook Air, but it doesnвЂ™t charge anymore.

When the AC adapter is attached, there is no green nor orange light on it.

It can save time to repair professionals or talented hobbyists. This article does not describe an easy fix, but a complex one. Just electronics on closed source hardware.
