MacBook Air Battery Won't Charge

I have searched far and wide to try and solve this issue but have had 0 luck. 


I have an early 2015 MacBook Air (A1466) that I've kept in great condition over the years. It's never really left my room/desk and I've gone far out of my way to keep it in this condition because of how much I like this computer. 


So, it had been a few months since I last used it (new job, work computer, travel all the time) and I realized the charger had been disconnected at some point meaning the battery had been likely sitting there completely dead for days, weeks, possibly months which I understand is not great for a Lithium-Ion battery?


I just tried to power it on for the first time the other day and it boots up, while plugged in, and loads seemingly normal but when the computer is finally completely started up the battery is indicated as "not charging" when clicking on the icon from the taskbar and the percentage is stuck at 1%. 


The orange light on the MagSafe charger is on when plugged in. 


The steps I've taken so far. 

  • Reset SMC a few times
  • Reset PRAM a few times
  • Option clicked on the battery to see a report and it shows as "normal" 
  • Downloaded coconut battery and that also shows as "normal" 
  • Checked the cycle count which is currently sitting at about ~310 which seems well under the expected failure point
  • Removed my battery and checked the inside of my computer for corrosion or any other type of damage, found nothing
  • Inspected the battery for any oddities or swelling, found nothing.
  • Tried multiple MagSafe chargers 
  • Charged another Macbook using my MagSafe charger


A friend of mine had me take some photos of the IO board to see if he could figure it out and isn't sure but seems to think there might be something up with that? https://imgur.com/a/sXTcq8J - IO board pictures.

The semicircular thing in the center of the first picture and also present in the others appears to be a piece of debris, which may or may not be conductive. Remove it.


... the charger had been disconnected at some point meaning the battery had been likely sitting there completely dead for days, weeks, possibly months which I understand is not great for a Lithium-Ion battery?


Yeah that's not great. Batteries need to be used and extended periods of disuse will kill them. That include long periods of being constantly connected to power.


If you decide battery replacement is warranted, have Apple do it: https://support.apple.com/mac/repair/service. They'll take care of everything including diagnosis and battery replacement, if it's justified. Batteries cannot be resurrected or fixed.

Thank you for your response! I'll open it up again and see if I can get that thing out.


Yeah, I know that's an option but from what I see online estimates are around $500 which is probably more than the computer is worth at this point. I just don't understand how the battery can be fried but none of the built in Apple battery diagnostics can detect ANY issues with it. Seems like if they can't detect completed bricked then those tools are useless.

That's what my question is. They quoted me at this without being able to diagnose or determine the actual issue. The chat rep. said that if the repair ends up being cheaper than I would get notified of a refund which seems super odd.


Unfortunately, I won't be able to address this in person until I'm able to go pretty far out of my way to a store.

Keep it simple. Go to an Apple Store and tell them your battery won't charge. They will diagnose what's wrong for $0. If it needs a new battery (which it probably does) it will cost $129 plus whatever taxes are imposed upon you. If it needs more than that, they'll tell you exactly what's required so you can make an informed decision.


Until they can inspect it they're working on insufficient information. That's the likely reason for such an unreasonably high estimate.


Don't divulge too much information regarding what you've done, because they don't like the idea of people opening up their Macs. Keep it simple: your Mac won't charge. That's all they need to know.

The reason why it's suggested is because it's far easier to explain things in person, and then discuss what is or isn't OK in terms of price and service.


There are Apple Authorized Service Providers, but they're not specifically Apple. Apple Stores don't charge for any diagnostic. An AASP probably will because it's costing them time. Apple Stores do diagnostics as a courtesy for Apple users.


As far as leaving a computer uncharged, I don't necessarily think that it's always that bad. It's just a crapshoot. I've had a battery that was likely at 0% for months, and it woke up and charged just fine. Last time I checked the battery was at 95% health. But yeah there's the possibility that it could go into deep discharge.
