Schematic in PDF format for the Apple MacBook Pro A1286, logic board 820-2330 at revision A, archived as RAR at 2.75 MB. Apple uses the 820-xxxx numbering for logic boards, and the number is printed on the PCB, so verify it before working from these pages. The schematic helps trace power rails such as the PPBUS and standby supplies, follow the SMC power-on logic and look up component values when replacing parts. Open the extracted file in any PDF viewer and use the page index to jump between sections.
