Schematic for the ASUS K40AB, part of the K40 laptop series, supplied as a 1.17 MB PDF. The name gives no board number or revision, so confirm the mainboard version from the silkscreen before measuring against the drawing. The document lets you trace the charging circuit, main voltage regulators and signal routing between chips and connectors, which helps when diagnosing no-power, no-display or short-circuit faults. Any standard PDF reader opens it, and its search tool makes finding nets and reference designators easier.
