Apple repair archive for logic board 820-2510 revision 1, with schematic document 051-7867 and project code K20 given in the name. The 051 number is the Apple schematic drawing code, so the contents are most likely the board schematic in PDF form. Use it to follow power rails, check enable and power-good signals and identify the parts feeding a shorted line. Check that the 820 number on the PCB matches before relying on it, as different board revisions can change parts and connections.
