PDF schematic for the Lenovo GS340 mainboard NM-C571, packed in a 2.70 MB RAR archive. The NM- prefix is the LCFC board numbering used for Lenovo designs. Circuit pages show power rails, the startup sequence, EC and charging circuits and signal routing, letting a technician measure the right points and identify component values. Pair it with the matching boardview to locate parts physically. Check that the board number and revision on the PCB correspond to the schematic before trusting it for diagnosis.
