Schematic in PDF format, 1.06 MB, named simply A6G with no brand or revision given. The name matches the pattern of ASUS A6-series laptops, but that is not stated, so confirm the device from the document title block and the board marking. Once matched, a schematic like this lets a technician follow the power rails from DC jack to regulators, check enable and power-good signals, locate test points and confirm values of parts near a short. It opens in any PDF reader with searchable net names.
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 @schematicslaptop. Enginerys does not host this file.
