PDF schematic for the Lenovo NM-C841 mainboard, an LCFC design with the project code GYGB0, packed in a RAR archive. The name does not state a revision, so compare the document's revision block with the board's silkscreen. The circuit diagrams cover power rails, the charger, EC and the power-on sequence, and help diagnose no-power and no-boot faults. LCFC, Lenovo's manufacturing unit, numbers its boards with the NM- prefix. Pair it with the matching boardview to place parts on the PCB.
