Quanta G74A board documentation at revision 1A, distributed as a 1.28 MB RAR archive. The file name lists only the project code without brand or laptop model, so identification relies on the code printed on the PCB. Quanta manufactures boards for several notebook brands, and such packages usually contain a schematic for diagnosing no-power, no-charge or no-display faults by tracing rails and signals. Check that your board shows G74A and revision 1A before using component values or pinouts.
