Schematic in PDF form for the N501VW, the ASUS N501VW laptop family, as named, with RG in the name, likely denoting a revision. It is 1.02 MB and opens in any PDF reader. Technicians use it to trace power rails, follow the power-on sequence, find component values and test points, and isolate shorts on the mainboard. The name gives no explicit board revision, so compare details such as the board number on the PCB against the diagram before trusting part references.
