Logic board documents for an Apple MacBook with project code K78, referenced by schematic number 051-8871 at revision 250, in a RAR archive of 1.15 MB. Apple uses 051-xxxx numbers for schematics, which appear in the title block, while the physical board carries an 820-xxxx code. Use the schematic to trace power rails, follow signals between chips and locate the parts responsible for a no-power or no-charge fault. Verify that the board in hand corresponds to the K78 design before relying on component values.
