Schematic in PDF format for the LCFC NM-E231 motherboard used in Lenovo laptops, packed in a RAR archive. The name gives no revision, so compare the revision noted in the schematic with the one printed on the PCB. LCFC is the Lenovo-owned ODM that uses NM- board numbers. The diagrams show power sequencing, rail names, signal routing and component values, which help with diagnosing no-power and no-boot faults. They work best with the matching boardview to place each part physically.
