Schematic PDF for the PU551JA motherboard at revision 2.0, a model name used by ASUS business laptops. Expect power sequencing pages, charger and VRM circuits and connector pinouts, useful for diagnosing no-power, no-charge or no-display faults and for following signals between chips. It pairs naturally with the 60NB07B0-MB1200 R2.0 boardview for physical locations. Read the revision marking on the PCB first, as values and parts can differ on other versions of the board.
