Chosen Solution
Hello! My Mid-2013 MacBook Air stopped charging entirely the other day, while I was using it. (I noticed the light on the MagSafe turn off). I continued using the machine until the battery was nearly dead, assuming I could just continue working and reset the SMC and fix the issue. Resetting the SMC did nothing. There is absolutely no light on the charger. I’ve tried three different chargers and couldn’t get a light on any one of them. I opened the machine, disconnected the battery and connected each charger to see if I could at least get a fan spin- nothing. Meanwhile, I could reconnect the battery and get it to boot just fine, just no power in, for charge or otherwise. I assumed the issue must be the I/O DC board and not the logic board, since the machine functioned normally otherwise. I ordered and installed a new I/O board to no results. Still zero light (orange, green or otherwise) and no fan spin. At this point, the battery seems completely dead, because I can’t get the blinking “CHARGE ME” animation or a fan spin at all. I removed the logic board to look for corrosion and didn’t see any, but gave the board a good cleaning with isopropyl anyhow. Unfortunately, I’m still not able to get any power to the machine or battery. Most of the situations I’ve found in the forums that look similar result in the user at least getting a light or a fan spin. I’m hoping that the community may be able to point me in the right direction! Is there any path I can explore further to diagnose where the issue is? I picked up a multimeter with the intention to learn to use it to diagnose issues like these, but I’ll admit that at this point, I have no idea HOW to use it. Although I’m willing to learn! Thanks so much for your help! Ethan
Let’s start at the charger, Is the a REAL Apple charger or a clone? Don’t Replace Your MacBook Charger With a Cheap KnockoffLacking safety features, cheap MacBook chargers create big sparks Apple - MagSafe Chargers If you have a real unit lets check the MagSafe connector interfaces: Apple Portables: Troubleshooting MagSafe adapters a common issue is the middle contact (one wire comm link to the charger) gets damaged
You’ll also what to check the system side as well clean the surfaces with a cotton swab and isopropyl alcohol and a new pink pencil eraser to polish the contacts. Let’s see if that gets you going. If not, you are likely looking at a problem with the SMC charging logic on the main board.
