PDF schematic for the LCFC NM-D511 mainboard used in Lenovo laptops, archived as a 1.03 MB RAR; no revision is given in the name. LCFC is Lenovo's own ODM and its boards carry NM-prefixed numbers. The diagram is the reference for power sequencing, rail voltages, EC signals and connector pinouts when diagnosing no-power or no-display faults. Check the board number on the PCB before using it, and pair it with a boardview of the same number to find parts physically.
