Schematic diagram for the Lenovo LCFC NM-C741 mainboard, version 1.0, delivered as a PDF in a 1.92 MB archive. LCFC, Lenovo's in-house manufacturing arm, uses NM-prefixed codes for its laptop boards. The circuit pages help a technician follow power rails from the charger IC through the regulators, check enable and power-good signals, and look up component values when replacing damaged parts. Any PDF reader opens it; confirm the board number and version on the PCB match before trusting measurements.
