Archive for Apple logic board 820-4924 containing both a schematic diagram and a boardview file, about 5.6 MB packed in RAR. Apple uses the 820 prefix for its logic board part numbers; the specific Mac model is not named, so confirm it from the board marking. The boardview opens in tools like OpenBoardView or FlexBV for locating components, pins and test points, and pairs with the schematic for following rails such as PPBUS and diagnosing shorts, missing voltages or failed power sequencing.
