Schematic package in RAR form for a notebook mainboard identified as Piano CM, project NB2250, on a CML platform (Comet Lake) with Type-C support, version V3. The archive name indicates the drawing is supplied as a PDF, readable in any PDF viewer with text search for net names. Technicians use such a schematic to follow power rails from the charger and PMIC stages, check enable and power-good signals, and identify components around a short. Confirm the board version printed on the PCB matches V3 before trusting component values or rail layout.
