Schematic for the Lenovo IdeaPad S550 on LCFC board NM-C811, delivered as a 3.61 MB PDF. LCFC is the Lenovo-owned manufacturer that uses the NM- prefix for its board numbers, printed on the PCB alongside the revision. The document covers power rails, regulator circuits, the power-on sequence and connector pinouts, so it is the main reference when diagnosing no-power or no-display faults. Open it in any PDF viewer. The name gives no revision, so compare the schematic revision with the board before relying on part values.
