Hi all,


I own a Macbook 13 inch air which I purchased in early 2012. My problem lies with the charging of my laptop.


The symtoms;


Macbook intermittently charges, but is now not charging at all

Mag connector is not showing any lights (being green or orange)

Laptop shows no charge increase with mag attached and no light


Took laptop into my apple store and they ran a 'diagnostic test' which showed everything as OK . I also noted that as soon as they plugged the laptop in the charger started charging the battery.


I then took my laptop home frustrated, after trying for the last week to get it to charge with no success. I plugged the laptop in and it started charging. Unusual i thought!


However now the same problem has came along again, with my laptop not charging and the mag light not glowing any colour.


Is this a hardware fault perhaps?


My software is up to date.


I have tried multiple known working plugs around the house.


The power adaptor is in excellent condition, it just sits in the same place and is never wrapped up etc and looks in perfect condition.


The power plug on laptop and mag are both clean.


Im really struggling to find any info as to what is wrong?


Any ideas?


Much thanks in advanced,


MacBook Air, iOS 5.1.1

    Your post is ambiguous.  Did the service provider also check YOUR power adapter with YOUR computer?  If not, that should be the first thing to check.  When the power adapter stops charging, does unplugging and then replugging in the power adapter (at the wall, and at the computer) cause the power adapter to start charging?

    Hi there,

    Sorry for not being clear enough with my problem. To answer the above questions ;


    My local apple store DID test my own laptop and charger. They both worked 'without fault' at the time - typical !


    The power adaptor works sometimes, about 10 percent of the time actually. Unplugging the charger / re plugging the charger / trying the charger on several different power points / plugging charger in at wall and computer and visa versa does not charge the laptop.


    I have noticed in the dark i can sometimes see a wee spark as the mag is connected to the laptop, so i presume this means the charger works fine or at least has power surging through it. This also backs up the apple tech's hardware test showing that the charger is in good order.


    Unsure what else to do, at this stage looks like i will have to take the laptop back to the apple store again and hope for a negative result so I can get this problem resolved .

    My early 2012 macbook air is having the same problem. Charger intermittantly charges the laptop. Electricity is flowing from the charger because when I plug it in the symbol on the laptop shows the charge symbol. However when clicking on the icon it says "battery is not charging" power source is power adapter.


    This is really frustrating because I need to charge my laptop and often times I will leave and it is still out of power.


    I have not tried to take it to the Apple store yet. Have tried unplugging and replugging, updating software and firmwire. Not sure what else to do.


    Please help!

    Hi there,


    I ended up taking my laptop in to my local apple store after much frustration with a similar case to yours. The 'technician' said the laptop had to fail a hardware test they run on the laptop there in order to log a fault and replace parts under warranty, they then proceeded to plug the laptop in and my charger worked!


    I ended up taking my laptop home, and it appeared the charger was functioning correctly once again.


    A few days later, same problem! I took it back to the apple store and thankfully it showed there was a fault in my charger, this was then replaced under warranty (9 days left to go, phew! )


    Best option would be to take it in to your local store is my advice, good luck!

    I am facing a similar issue. The laptop stops charging intermittently. Right now it happens every couple of day, maybe for 10-15 minutes only. Not sure, if it is going to get worse with time.


    Replaced charger but the problem persists - so, looks like the issue is with the laptop itself.

  • bmorehon Level 1 (0 points)

    I am having this exact same problem and it's been going on intermittently for a few months. Sometimes when I plug the charger into the laptop no light appears. I've tried using different outlets all with the same problem.  Then, when I'm just about to lose hope and head to the Apple store it lights up mysteriously.  I'm wondering if it's possible that the charge gets so low in the laptop that it takes time before the charger lights up?  Or perhaps my charger is going bad.  What I'm afraid of is that this will happen exactly when I need the laptop the most and the inability to charge it is just not acceptable.


    If anyone has diagnosed this problem please speak up.

    Same problem here, it's kind of annoying. I tried someone else's adapter, and then my MacBook Air charges fine. When I switch back my own charger doesn't charge.

  • regilapa Level 1 (0 points)

    I am having the exact same problem; early 2012 mac book air (11.6 inch); charges in seemingly random and unpredictable ways; at times it will start charging after 3-10 or so min of being plugged in, and sometimes, like today, it won't start at all (even though battery is at ~70% in either scenario). Any solutions so far? The cabling in the cord per se is not broken, as when it does start charging, it happens on its own (i.e., independent of any mechanical intervention).


    The power cord that came with my 2007 mac book pro, on the other hand, is always able to get this macbook air to charge... Is permanently switching power cords a (non-ideal) solution? I.e., are there any cons to switching to a power cord from an older computer?

    One more here in the "me too" category. 


    11 inch Macbook air. The Charger worked fine for months. Now, about 60% of the time, if I connect the power cord, no indicator light, and obviously no charging. I also note the charger brick itself does not get the slightest bit warm.  If I leave the power cord plugged in (Sometimes for more than an hour) it will rectify itself, given time. Its very strange.


    I have no access to another charger yet, so I can not test this, but multiple sockets including home and work, ruling out issues at the source.


    So, the scenario is the power cord, plugged in, no light, no charging. Left alone (and I have repeated this at least 20 times now)  the light eventually comes on, charging begins and all is well.


    The only variable that I can think of is room temperature. Which I dont think should vary too much in the rooms that i have been in.

    Heat up the power brick using a blow dryer for a couple of minutes. It may sound stupid but I did it when my MBA started choosing when it was going to charge and the led did not light up.

    Reply and tell me if it works for you guys.

  • jfkemper Level 1 (0 points)

    I can't believe it - I was having the 'no charging' problem and I took your blow drying advice and it starting charging a minute later.  Go figure, and I live in SoCal.  I started having intermittent charging problems beginning about a month or so ago.  tried different outlets, reconnecting power from mac side and outlet side, etc.  Thanks for the hot tip, Stone.

  • regilapa Level 1 (0 points)

    After reading these last couple of posts, I decided to try to "warm up" the power cord/brick by placing it on top of my radiator, and bingo! It works, for 2 days now, whenever I try to plug it in and it won't charge,  leaving it by the warm surface for 5 min and then trying to charge again has been working like a charm. WTH?! Thanks for this crazy tip!

  • cdlaurion Level 1 (0 points)

    I am having the same issue with a Mac Book Air 4,2.  I have tried multiple power bricks with no luck and the heat up didnt work for me.  I think there is an underlying problem int he MBA itself as it is completely random when it decides to charge vs state Battery not charging (green light)

  • Haulewood Level 1 (0 points)

    Same problem with my MBA.  The blow dryer trick worked. Only problem is that I got the MBA for travel and it kind of defeats the purpose if I have to pack a blow dryer too.  Has anyone determined what causes the problem?
