    Hey guys!! I promise i didn’t make this account just to post one question and never post again!

    But, long story short i have a Early model 2015 MacBook Air 13” that i bought cheap to try to fix up and have for school. I got it cheap because, well the lady i got it from couldn’t get it to turn on. Lol but I’m determined to figure this thing out! So let’s get to the meat & potatoes..

    When i plug in the MagSafe 2 adapter.. the green light comes on, then goes amber in an effort to charge the battery so I’m guessing the adapter is good. When i press the power button the book does NOTHING literally. I have tried resetting the SMC, which turns the light back green for 0.5 secs then goes back to Amber. So the keys are working properly. I’ve also tried resetting the ram as Apple recommends. So i decided to dig a little deeper. I took the back cover off the mba, unplugged the battery to see if she would come on with power to rule out a battery issue and...!!!! Not a damn thing. Still does everything the same as if it was plugged in. I’ve also discovered that when i try to turn on the laptop the fan comes on for a few seconds then shuts back off. Doesn’t studder a couple seconds, nothing. Just does it once. So i took the logic board out and it is now setting on my desk with the fan and i/o board connected, so me and you guys can do some diagnostics. With it sitting on my table, the MagSafe adapter goes green when i first plug it in, then goes amber like it’s charging the battery. -isn’t it supposed to stay green if there’s no battery connected??

    Thank you guys,
    Hopefully i didn’t mess up investing $85 in this... lol
    PS: I’ve also tried crossing the power pads to get it to turn on. Doesn’t do a thing. Don’t even turn the fan like it does when i plug it in.
    PS2: she told me after i had already bought it—that she didn’t drop it EVER and it hasn’t not had anything spilled on it. And after close visual inspection i don’t see anything Gunked up.

    Without a proper multimetre and schematics, it would be tough to diagnose. There are fuses, capacitors, and resistors on the board that may have blown.

    It's possible that the I/O board is defective.

    I also have a Macbook air sitting on my desk that won't turn on. At least you get the fan to spin on yours. I'm probably going to take it to my local shop for a proper diagnosis and estimate to repair.

    Now thats a cheap fix. That would be great if that were the issue. I love ifixit.

    Keep us posted OP.

    Hey I’ve got a stupid question. I have a friend that has a 2015 or so MacBook Pro that doesn’t work. Will the logic boards and I/O boards be the same on the insides of these things?? Just for shots and giggles... wondering how different the pro’s and air’s are. I’ve already ordered one either way. Like what parts are enterchangable between all these devices? Im getting into the rebuilding thing with these and was just wondering the years and models etc.

    The only thing that will work between the two is the SSD and the wi-fi/Bluetooth card.

    So literally the only (for the most part) internal parts that will fit my computer is the 2015 version of the 13” Air? Am i getting this right? Lol. What about the different size screens? Like the 2015 11” MacBook Air or something? Are they different too? Sorry for being a noob! Lol

    The parts that will fit an early 2015 13" is everything from a mid-2013 13" Air to 2017 13" Air.

    The SSD and Wi-Fi card from the mid-2013 to 2015 11" Air will fit the early 2015 13" Air. I'm not sure about the trackpads from the 11" to 13" Air. I know the keyboards are definitely different.

    Great. You guys will hear plenty from me because for some reason i enjoy working on these things. I guess it’s because there’s like literally 2 boards in the entire box vs the normal (desktop) computers that I’m used to building!

    I got the new i/o board in today and the new one is sadly doing the same thing, and it came out of a working MacBook Air.

    Oh no, that means there is something wrong with the main logic board.
