PDF schematic for a Quanta G35 motherboard, around 3.1 MB in size. The revision field in the name is truncated to a single letter, so the revision is unknown, and no laptop brand or model is given. The diagrams can still be used to follow power rails from the adapter and battery, read the regulator circuits, locate test points and check signal continuity to connectors. Since the revision cannot be confirmed from the name, compare the component layout and values against the actual board before relying on it.
