Apple A1286 schematic for logic board 820-2330, revision A, supplied as a PDF packed inside a RAR archive of 1.83 MB. A1286 is the Apple model number printed on the bottom case, and 820-xxxx is Apple's own logic board numbering, so the number silkscreened on the PCB must match before you rely on the pages. Extract it with WinRAR or 7-Zip and open the PDF in any reader to trace power rails, follow enable and power-good signals and identify parts by reference designator when chasing a short or a no-power fault.
