Archive for the Apple MacBook Air A1466 from 2012, logic board 820-3209 revision A. Apple numbers its main boards with the 820- prefix and marks revisions with a trailing letter. The 2.73 MB RAR likely contains schematic and possibly boardview files for this board. Technicians use these to follow power rails, find test points and isolate shorts around charging or CPU power. Confirm the PCB is silkscreened 820-3209-A before relying on the documentation.
