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?

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....

I have

Macbook A1466 2017 EMC 3178 A-820-00165-A
It was bad soldering SPI before (I guess somebody have been trying to fix it before)
I have found problem, it runs, but when I am trying to install OS it is interrupted.


I think error is here:

panic CPU caller 0xffffff0014a8c5c0


Would somebody can help me to find what problem is?


Thank you...
