Schematic for the LCFC board NM-F861, a Lenovo notebook mainboard, supplied as a PDF inside a 1.97 MB RAR archive. NM-xxxx numbers belong to LCFC, the Lenovo-owned ODM, and this name gives no laptop model or revision. Use the diagram to trace power rails, the charger and EC circuits, and signal paths when diagnosing no-power or no-boot faults. Match the NM-F861 marking and the revision silkscreened on the PCB before relying on part values, since revisions can differ.
