Schematic PDF of 2.29 MB for the N56VM laptop mainboard, carrying the RG tag of ASUS repair guide documents; no revision is given in the name. The diagram covers the power circuitry, CPU and graphics sections and connector pinouts, and is used to trace rails, find the source of a short and verify signal paths during board-level repair. Open it with any PDF viewer. Compare the board name and revision printed on the PCB with the schematic title block, since component values can differ between versions.
