    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.

    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.

    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

    Macbook Air A1466 EMC 3178 missing power and liquid damaged
    by BMCappelletti
    Hi everyone.
    Macbook Air A1466 EMC 3178 (board 820-00165 A) not turning on and no charging light. Completely dead. With no battery connected it would power up and I could hear the chime, but nothing on the screen and then a sudden turn off. Sometimes during the chime. Opened it up and found some liquid damage. The flat that connects both boards has damage in one side (with a missing pin already). The connectors on the boards are fine, though.
    Also, there was liquid damage on the included picture area, which are R8111 and C8111. A quick and soft brush on it made the resistor be gone....

    MacBook Air A1466 2017 Operating Very Slow
    by ACS-Repair
    I'm hoping someone can help me with a 2017 MacBook Air A1466 820-00165 that is running very slow. This is a board that I picked up on ebay recently.
    This is not being caused by a sensor issue. All sensors report normal operation and the fans run at normal speed. Geekbench gives me a single core CPU value of 124, when it should be closer to 400. I was unable to complete an install on the SSD without putting it into a different computer first.
    The board appears clean with no sign of liquid damage. I have done a PRAM and SMC reset, and I have done a reflow of the SMC. I have inspected...
