MacBook Air won’t charge or turn on

The day before the MacBook Air died it notified me the battery needed replacing and laptop would immediately shut out if disconnected from mains power as the battery wasn’t holding any charge. The next day, having been left connected to mains power overnight the laptop won’t turn on and the MagSafe 2 light is off. I tried a different connector and it still didn’t work.

I have now replaced the battery but this didn’t work.

I have checked circuit board for corrosion and can see none, wiped off some dirt with alcohol, but still no change.

No idea what to do now, I’d be extremely greatful for any suggestions!

This is what the charging port looks like:

You’ll need to walk though the pathway from the charger to the system. Is the MagSafe charger cable in good shape? Make sure it doesn’t look like these

So it does sound like you'll need a new charger for starters. Here's a like to Apples website to get the needed charger: Apple 45W MagSafe Power Adapter for MacBook Air

You may also need a new MacBook Air 13" (Mid 2013-2017) I/O Board Here's the guide to get to it MacBook Air (13 Zoll, Anfang 2017) I/O-Karte tauschen. I do fear you may have a deeper issue in the main logic board as well.

I will upload a picture below. There is possibly some minor scorching around one of the pins but is extremely subtle if thats what it is. Having done a bit of research on this site I think the problem may have been caused by using a knock off magsafe 2 charger, as that is when the trouble started. The other charger I tried after that was an official magsafe1 charger with official adaptor but even though the light came on the magsafe1 charger, the laptop started to turn on and then turned off again with it.

Thanks for this. Is there anyway to identify ahead of time which parts will need replacing as I do not have a lot of money.


@emidude - I would start with getting a new charger (real Apple unit), someone with the deeper micro-electronics skills might be able to fix the I/O board sensor line circuit, but that will also cost you so I'm not sure if that's cheaper. In any case this all needs to work before you can tackle the logic board.


@danj I do have an official 60w MagSafe 1 charger and official MagSafe 1 to MagSafe 2 adapter and I’ve head that (at least when everything is working) you can use a higher wattage to lower wattage (my MacBook Air is 45w) without problems. However, after I used the non brand charger and my battery stopped holding any charge, it would not even turn on with the official MagSafe 1 to MagSafe 2 setup. It would at that stage still turn on with the non brand MagSafe 2. Sorry for the rambling. I have found some suggestions online such as reset the smc but I am unsure whether to try this with the 60w charger. If it is all official apple is there any risk using a higher wattage after resetting smc?
