What is BIOS?
BIOS is programming that controls low-level hardware operations, including interactions with diskette drives, hard drives, and the keyboard. The BIOS is stored on a chip. Your computer uses flash BIOS, which can be updated through a program on a flash diskette so that you do not have to replace the BIOS chip to update the BIOS.

Hello guys.
I am working on a Macbook Air 2015 logic board 820-00165 that has no sound. There are no audio device visible.
Replaced audio DC Board.
Reflash bios (clear ME)
Replaced SMC
For some reason it still don't give any sound
So I am now tired and it seems this board will soon go to the bin.
There are no corrosion on the board and I also replaced U6410
Maybe somebody on this forum could guide me.
I don't understand how the sound is produced exactly on this board.
J9500 looks fine all pin are connected and no corrosion.
thanks in advanced for response.
