PDF schematic for the K72JK motherboard, an ASUS-style model code, though the name gives no revision. At 2.02 MB it should cover the full board, including power supply stages, charger, CPU and chipset rails and the graphics section. Use it to trace rail generation, read enable and power-good signals and identify the components around a fault. It opens in any PDF reader. Compare the revision printed on your PCB with the one in the schematic title block, since revisions may differ in part values.
