    Macbook A1466 820-00165-A - wont turn on

    Hi,

    I'm having issue with this macbook. No liquid or corrosion found on the board. I'm not quite sure what to measure so would appreciate some advices.

    Weird thing I noticed is that charging voltage on the battery pin is droping from 8.5v to 0v and than jump back to 3.3v after a while resets again and jumps to 8.5v. I think there may be something wrong with a charging circut.

    Unfortunately I've got a non original charger so I'm not able to check what LED shows. However that laptop is working fine as i tested it with different laptops.

    I've checked voltage on all the coils and I'm getting voltage only on 2 of them. 3.3V and 8.5V, rest is 0v

    Please help guys

      Suggest to source an original and recommended charger and test again.

      If you remove the battery, any difference with the logic board?

          MacBook Air A1466 does not turn on from keyb ON/OFF button
          by mferna14
          Dear buddies., working on a MacBook Air A1466 (Logic Board 820-00165-A 2017). The logic board turns on fine (This is all done without battery) & the Magsafe jack is lit to orange. I boot it up to OS. Once I shut it down, it does not turn on again unless I remove the magsafe 2 jack & put it back again. There is no liquid spill & the voltages seem to be fine. I re-build a new BIOS & CleanME region done, but the problem still exsist. Once shut down, does not turn on from the keyb power ON/OFF button. I put in a new keyboard & the MagSafe/Audio board & a new flex cable too,...

          Liquid damaged macbook A1466 fan spins, but doesn't turn on.
          by redbaron1007
          I got a tricky one today in the form of a macbook air A1466 820-00165-A that will recognize the charger and turn the light green then back to orange and the fan will spin constantly, but the system won't power on. The screen never turns on, it doesn't make the bong noise it's supposed to, and pressing the power button doesn't do anything. When I took the board out to visibly inspect it I only found one spot of corrosion on the bios IC. I pulled the chip, cleaned it and the area with IPA and put fresh solder on both and put the bios chip back on, but when I went to test it again it still does the...

          Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
          by Ryan.man
          Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

          My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

          This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

          Macbook Air A1466 820-3437-B Booting Problem
          by psdavid65
          I received a 2013 Macbook Air A1466 820-3437-B motherboard with serial number C02L6GQ9FSV8 that came in WITHOUT a bios chip. I got a new bios chip and reprogrammed it. Macbook now powers on but doesn't boot the SSD. I've flashed a ton of bios but still same problem. Windows installation works with this Macbook but never a mac installation. Unfortunately, since I didn't receive this macbook with a bios chip, I don't have the original bios. What can I do now?...
