Apple MacBook logic board boardview for board number 820-02841, supplied as a .CAD layout file in an 808 KB RAR archive. The name does not state the exact MacBook model, so identify the machine by the 820 number printed on the logic board. Apple uses 820-xxxxx numbers for its main boards. Load the file into FlexBV, OpenBoardView or a similar viewer to trace PP rails, find capacitors on shorted lines and locate test points around the charger and power circuitry.
