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.
