    Macbook air a1369 emc2469 boot issues

    Got a macbook air that fails to boot from any drive be it external or internal. It just shuts down when the progress bar is about 25%. After it's off i can turn it on normally with the power button. I tried flashing a clean ME efi but there wasnt any difference. What could be the issue here? I can take measurements on the board if needed. There is a bit of liquid damage on the back of the board. I uploaded it to the drive folder. And also here's the video footage. https://drive.google.com/drive/folde...DzIb6YHjc9RMvh

      cleaned with alcohol and no difference. Do you think a solder reflow would help?

        Try booting in safe mode.

          Safe mode booted fine with the screen blacking out constantly. Then I disconnected the ribbon cables one by one and after disconnecting keyboard it booted just fine! Lmao thanks for the replies!

            Macbook Pro mid 2015 battery required to boot?
            by twonk9098
            I have read many forums that state the Macbook Pro 2015 needs / does not need a battery to boot. I'm not convinced as yet which is correct.
            The Macbook Pro mid 2015 I have has no battery and do not really want to buy one just to test.
            This model has the newer trackpad which is not clickable when turned off.
            At the moment, without battery it does turn on with no display (with backlight), no chime and then turns off after 13 seconds. I see this from the power draw on my DTPS.
            If I hold the power button whilst connecting the magsafe 2 charger it turns on, again no image but...

            Macbook A2251 no boot
            by PITERPENY
            The MacBook does not boot. It is restored via DFU without errors. The MacBook charges and consumes 20V/2A. There is no sound when connecting the charger. The caps lock does not light up, but the touchpad clicks. The fans do not rotate. No signs of life. Please advise.

            MAcbook Air A1466 EMC 3178 - 2017 Boot
            by Sergio Kub
            Could someone help me?
            I have a Macbook Air A1466 EMC 3178 - 2017, board 820-00165 and sometimes the boot interrupts with an image of a folder and a question mark.
            Could it be the BIOS?

            1708 EMC3164 macbook have power issues
            by itzusman
            Hi Masters.

            My 1708 EMC3164 macbook have power issues. First it was working fine but a bit slow in booting. Net day i turned it on and it didn't powered on. And i tested with usb meter it suddenly @ 20v it takes 2.6 ampares and cpu gets hot. Then i checked the baord and PPBUS_G3H was short to ground. I injected 1v to it it takes 350ma and cpu gets warm. After opening L7410/20/30 there was inly L7420 line was short then i injected 3v to PPBUS_G3H and it takes 2.5 amps and U7420 got hot and i desolder it. Now after that in the start it takes 0.580 amps and goes to 620-30 mili amps....
