Quanta schematic for the LG9 project, marked PV with a 0720B code and an X4 QCMC tag in the name. PV generally means production-validation stage, which is close to the shipping design. The exact meaning of the other tokens and the target laptop brand are not stated. The PDF is about 2.4 MB and is useful for tracing power rails, reading connector pinouts and following the power-up sequence when diagnosing no-power or no-boot faults. Check that the project code on the board matches before use.
