Lenovo G40-70 laptop schematic for LCFC board NM-A361, a 2.70 MB PDF. LCFC, Lenovo's own design and manufacturing arm, uses NM-xxxx numbers for its motherboards. No revision is stated, so compare the version marking on the PCB with the sheets. The diagram helps trace the adapter input, battery charger and system rails, follow embedded controller and power sequence signals, find test points and look up component values when a board is dead or shorted.
