Archive for the Apple A1370 MacBook Air, logic board 820-2855 revision A, about 1.36 MB in RAR form. The name does not state the exact contents; at this size it probably holds schematic or boardview material or a firmware image, so open it to check. Apple's 820-xxxx numbering identifies the logic board, and the revision letter must match the PCB being repaired. Such documents help trace power rails, find test points and diagnose shorts on the board.
