Schematic for the ASUS FX505GM gaming laptop, revision 1.0, provided as a 5.07 MB PDF. It documents the board circuitry such as power sequencing, charger, CPU and GPU voltage regulators, memory and connectors, so a technician can trace rails, check signal paths and identify components around a fault.
