Circuit diagram for the Quanta Z07 notebook mainboard, revision 1A, in PDF form at about 1.04 MB. The file name gives no brand, model or chipset, only the Quanta internal project name and board revision. Quanta designs boards for several laptop brands, so check the code etched on the PCB, usually beside a DA0-style part number, before using it. Typical uses include checking standby and main rails, measuring voltages at regulators and following signal paths between the controller, chipset and connectors.
