Quanta AT3 motherboard schematic at revision R1A, here as the fourth copy of a 1.26 MB PDF. Quanta assigns codes like AT3 to laptop boards it designs and builds for other brands, and the code normally appears on the PCB. Technicians open the document in a PDF reader to follow the charger and system regulators, read connector pinouts, check signal routing and look up reference designators. Compare the board revision with the drawing, as later revisions may change parts.
