Circuit diagram for the Quanta SA1 board at revision 2A, delivered as a PDF of about 1.01 MB. SA1 is a Quanta ODM project code, and the finished notebook may carry a different brand name. Repair technicians use such a schematic to follow power rails from the DC jack through the charger IC to the system regulators, verify signal paths, and identify components near suspected shorts. Any PDF reader will display it. Check the revision etched on the motherboard first, because an earlier 1A board can differ from this 2A drawing.
