    A few days ago, my macbook battery would no longer charge. When I plugin the adapter, the small light does not turn on. When I click on the battery, it says: "Battery is Not charging Power Source: Power Adapter".

    So the adapter is working, since the computer is running on the adapter. The only problem is that the battery is not getting charged.

    Also, when I plugin the adapter, the computer does not always sense that it is connected to adapter. I have to plug and unplug 5-6 times (sometimes 15 times!) until it finally senses that adapter is plugged in, only then computer starts working on adapter power rather than battery. I even bought a new AC adapter, but same results.


    However, rarely, battery does start charging...like once every 2-3 days, then if I unplug adapter and replug, stops charging.


    So I called apple, they said the battery needs to be replaced. I bought a new battery from Amazon and replaced it, battery is working good, but still not charging, and still have to plug/unplug few times until computer recognizes adapter is plugged in.


    So to summarize...I have 2 problems:

    1. Mac doesnt always sense adapter is plugged in...have to plug/unplug few times.

    2. Even when it recognizes adapter, Mac only runs on adapter power...but DOES NOT charge the battery (except in rare cases)


    I replaced battery and adapter, but not solved. So the problem is from the computer, not from the battery or adapter. The part of the Mac that is supposed to tell the adapter to charge the battery, is not working except in rare occasions, and the part that senses adapter is connected doesnt always work properly.



    I tried SMC reset, no good.


    Is the mac damaged?
    Any solutions?

    Which MBA model is it? How old? Which OS? If you don't have Coconut Battery installed please do so. What does it say about health, charge cycles, full charge capacity?[​IMG] [​IMG]

    If you swap in another charger -- same problem? Also, look at the MagSafe connection. It's magnetized, and attracts things that can affect the connection.

    I uploaded images of coconut battery with all details.

    I used another adapter, same problem. I also made sure there was no dust on the port. Screen Shot 2017-01-07 at 6.56.53 PM.png Screen Shot 2017-01-07 at 6.56.23 PM.png

    hi Well you know; more or less; the battery doesnt charge a bit . Thats because the battery like all batteries has a very limited time a-mounted to it . Its more deeply because the Macbooks battery like every computers battery (even the Linux battery) is on all the time . Then you look at Mac again . Youre drawn irresistibly to Mac and nothing except Mac "aha haha" . Because its Mac .

    It only shows 1 cycle? Weird. And the battery has been exchanged. Who did this?

    I would try cleaning the MagSafe port on the computer. I would shut down the computer and delicately wipe the MagSafe port with a clean, dry cloth and see if that makes a difference.

    If not, I'd probably try something that I'm sure is unsanctioned: using a Q-tip with a small amount of rubbing alcohol to clean the port. It is entirely your call whether or not you want try this latter step.

    If that still doesn't help, my guess is that there is some sort of internal damage or decay to the computer's MagSafe port and or the charging circuitry. Maybe the right person with the right diagnostic tools with physical access to your device would be able to identify the real problem, but no one here can access your device.

    Good luck.

    I'm assuming that you just replaced the battery yourself? It says Anker suggesting you used a 3rd party manufacturer.

    You probably want to make sure that your battery is connected properly to the logic board. I just (as in 1hr ago) replaced my battery in my 2013 MBA and getting that connector in was definitely the trickiest part. If everything else is working but there is no charging and a SMC won't fix it my guess would be something is wrong with that connection. Unplugging and replugging in might help?

    You could also try reinstalling the old battery (if you still have it) to see if the new Anker battery is dysfunctional.

    EDIT: just realized you replaced battery AFTER the issues started. Sorry...

    You haven't mentioned this in your initial post. It is very important, though as the behavior "might" be related to this. As has been mentioned, I'd let the MacBook get checked by a pro.

    When coconutbattery lists the number of cycles, is it counting each time the direction reverses, such as 75% to 100%, or does it count full cycle equivalents? By full cycle equivalents, I mean four charges, as in the first case of 25% each, equals one cycle.

    Thank you all for the input.
    Unfortunately none of the quick fixes mentioned here solved the problem, so I guess its a hardware issue that needs a pro to see. And unfortunately I'm out of the country for a few months thus cannot go to apple store.

    Not sure if you managed to resolve the battery charging problem, but in my case, it happened once before, and yesterday after upgrading to 10.12.6 on my MBA 2015.

    You should try resetting the SMC. That solved the problem for me both times.

    Note: I am using the older MBA charger with a MagSafe to MagSafe2 adapter, not sure if that is relevant.

    Try resetting SMC for sure. It fixed my MBP and MB.
