PDF schematic for the Quanta R62 project, 2.43 MB, with no laptop brand or revision stated in the name. Quanta uses short alphanumeric codes like this for its notebook platforms, printed on the board as part of the DA0 number. The schematic lets you trace circuits from the DC input through the charger, the system power rails and the CPU VRM, check component values and follow enable signals. Compare the cover sheet revision with your PCB before relying on it.
