The best DIY repair video of MacBook Air here in youtube. Good job!

Thanks man.
I ordered a battery thinking that was the issue.
Turned out it was not.
I followed your video very carefully, .. I cleaned a few spots on the back of the motherboard with just Isopropyl Alcohol and a soft bristle brush.
A few spots that looked a little corroded.

Without a doubt the fan kicked on to my surprise, and the light on the charging cable turned back on.
This video saved me a lot man thank you.
Very much appreciated!!

This video seems quite legit... Everything done on camera without even a single cut of video. Thanks man...

Followed step by step, it was just the same. I used Isopropil (just a little and allowed some dry time) to clean the board. Put it back, checked the voltage values, they got it all back. Thank u. Very well explained video.

I'm looking at my sons Macbook Air - identical to the one in your video.
It seems there are two problems evident:
1) the SSD is not being recognosed at all - it's a 512GB Samsung blade
2) the battery is not recognised as being present
I have restored the OS (Yosemite) to an external USB hard disk and the machine boots.
Apple Diagnostics tells me there is a problem with the battery and a storage device. Great!
Apple Service Diagnostics (ASD 3S156) says pretty much the same. It does not indicate mothernoard problems and as I say, it boots.
I don't mind spending money to fix it, but don't want to spend it on the wrong stuff. Naturally I don;t have spares to play around with.
It suffered light liquid damage.
Anyway, your video gives me some things to try.
Muchas Gracias :-)

Thanks for the video.... I messed up two big things: I put battery back in and didn't screw it down... then when I re-removed the bottom panel the battery stuck to it (the little plastic tab in the center of the bottom cover) and this pulled the battery connector off the logic board. I persevered w the water repair... also screwed up the speaker connection (didn't pull it "UP")... I found corrosion on the board once i got it out... cleaned it w denatured alcohol (It was only wet for 24 hours and I had it drying without case within 12 hours). Fan is on so power is getting to it but won't turn on... I am going to leave it for 24 hours and maybe clean again. I am also going to pull SSD and try in another MacBook Air (older one) -- this one is 2017 and not even paid for.... One thing to suggest: coach on the connectors a bit.... pull this one UP (I wish I'd read the comments that said watch out for speaker connector). Battery connector was just bad luck as I've not had that happen w MacBook Pro I kept running for years after a cup of tea was spilled on it. THANKS AGAIN. I can't do the testing/solder cleaning but still I gave it a go. I might try to have the board repaired by a shop... I guess we will see.

Thanks for sharing this video. After getting $570 repair quote from apple I saw your video and bought the tools for $7.99 from Amazon. now I fixed my son's Macbook Air and it is working better than before.

How do we know if Logic Board is still working when Mac won't turn on?

[NicleT]

Thank you so much. I’m running into the same MBA with similar symptoms and was about to soak the logic board in an ultrasonic bath. But I’ll take a closer look around this bios chip.

[topalecom]

Great video ! Question.. after you put it back together and tested the keyboard was the WiFi con disabled? Or enabled ? Do we need to do anything for the wifi card to be detected ?

[ScottDCole-bcdf]

Thanks for the great video! I was able to tear my MB Air down, find the corrosion on the flip side of the mother board, clean it up, and that did the trick! Back in business !

Brilliant Tutorial Sir, I enjoyed every min of it, I don't know if anyone as mentioned but your mike goes off when the scope is on. Regards

[CharlotteBeasor]

Misses spilt a bit of champagne on hers, tried all the resets and PRAM but nothing worked just the fan. Took it apart and cleaned the logic board with rubbing alcohol using a toothbrush. Once all back together came on for ten mins then died again, I was gutted. However next day came on no problem and so far has been working fine. Massive thanks to you for this video as I would never have tried that.

[mohaargurpreet]

Thanks for the video. I fixed mine. I was too lazy to get 99% alcohol so used drops of crown royal, lol. After cleaning the corrosion, it did work fine

[lloydmurdock]

Apart from the lighting and audio issues, great video.

I had this same MacBook that had coffee spilt on the keyboard on for repair today and in the end it just needed a new trackpad. Thanks for the video that gives a good step by step strip down!
