    MacBook Air 2017 A1466 EMC 3178 820-00165-A No power

    Hi, I' ve this MacBook Air with a strange problem. This laptop come in to my shop with initial problem PULSING (ON/OFF, no fan)

    I wrote this attached bios dump that I clean me region by ME INJECT software and Macbook Power on but have a strange defect.

    The Macbook Power on only when I connect the AC adapter without battery. It Never power on by clicking power key on keyboard. I also tryed to power on by SMCbypass on the motherboard.

    When Macbook is ON and I press ON/OFF key the macbook go off without problem

    I tryed to clean me region using FIT but I can't find efi payload for this model MBA7,2.


    Can anyone help me?

    Did you make a bios backup before you started ? .MEInject isn`t recommended for anything over ME 6 in my opinion,and certainly shouldn`t be used with apple ME fw . Post the original bios backup

      What was pulsing on / off?

      Please post more details.

      Very possible that you have a defective battery.

      Restore your bios and post your voltage rail that is pulsing.

                            Can you tell me if this EFI is specific to the 2017 EMC 3178 or is this for any 820-00165 board? I have an EFI ROM file from a 2015 board and it doesn't start up on my 2017 board. I have heard that the EFI for this model is specific to the 2017. Can someone confirm this either way?

                              if you have the same board, change the Serial Number S / N, and clean the region me, and do the test, don't forget to do before writing on the chip, a backup of the original bios of the laptop.
