Lenovo G40-30 schematic for motherboard NM-A311, delivered as a 1.65 MB PDF. NM-A numbers belong to the LCFC numbering scheme used for Lenovo-designed boards, and the exact number with revision is printed on the PCB, so confirm it before relying on component values. Technicians use the drawings to follow voltage rails, trace enable and power-good signals, find test points and identify the part responsible for a short, overheating or a no-boot fault. Any standard PDF reader opens it and supports searching net names.
