Apple schematic in PDF format for logic board 820-02100, numbered in Apple's own 820-xxxxx scheme used for MacBook boards. The 3.5 MB document is used to trace power rails, follow the power-on sequence, check signal paths and identify components when diagnosing a short or a board that will not power up. Open it in any PDF reader, ideally alongside the matching boardview. The name gives no model or revision, so confirm the 820-02100 number printed on the logic board before relying on values and part references.
