Quanta R23 motherboard schematic, saved as a 900 KB PDF and matching the size of the other R23 copies in the index. The file name lists only the project code, so the notebook brand and board revision must be read from the title block in the drawings. A technician would use it to trace the power-on sequence, check voltages at regulator outputs and identify connector pinouts. Quanta board numbers follow the DA plus project code plus MB pattern; check the one printed on the PCB before working from these sheets.
