Schematic diagram for the ASUS K46CM notebook mainboard, supplied as a 1.24 MB PDF readable in any PDF viewer. The name does not state a board revision, so compare the version in the title block with the one printed on your PCB. Use the schematic to trace power rails, check the power sequencing, identify components on a shorted line and follow signals between CPU, chipset, EC and connectors. It pairs well with a boardview of the same revision for locating the physical parts and test points on the board.
