Schematic PDF labeled G501JW_RG, which matches the naming of the Asus G501JW model, although the name states no brand or board revision. RG may refer to a variant or a document section, so confirm its contents after opening. The 1.30 MB file can be used to trace power rails, check the power-on sequence and locate components involved in shorts or missing voltages. Compare the model and the mainboard markings on the PCB with the title block before relying on the diagram.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @hrtechno. Enginerys does not host this file.
