Schematic PDF for the ASUS G53SX notebook; the RG tag suggests a condensed reference or guide document rather than the full circuit set, and at 395 KB it is likely only a few pages. Use it in any PDF reader to check power sequencing, rail names and key circuit blocks while diagnosing a board. No board revision is stated in the name, so cross-check against the revision printed on your PCB, and pair it with a full schematic or boardview for component-level tracing of faults.
