Schematic in PDF format for the X453MA mainboard, about 1.43 MB, marked RG, which on ASUS-style files usually denotes the revision release; no brand or revision number is stated in the name. The diagrams cover power sequencing, charger circuitry, memory and peripheral connections. Use them to trace missing voltages back to their regulators, read enable and power-good signals and identify components on a shorted rail. Any PDF viewer opens the file. Pair it with the matching boardview and confirm the PCB revision before replacing parts based on it.
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 @cyberlanelectonik. Enginerys does not host this file.
