PDF schematic for the LCFC-built Lenovo mainboard NM-A121, project name VENUS2, revision 0.2. LCFC is the Lenovo-owned ODM behind NM-numbered boards. The diagram shows the power sequence, rail generation, EC connections and signal paths, so you can trace a missing voltage or a shorted line back to its source. Because 0.2 is an early revision, compare component values and designators against the actual board. Pair it with the NM-A121 boardview to locate parts physically.
