Schematic for the Lenovo G40-70 laptop on board NM-A361. The NM-xxxx numbering is the pattern used by LCFC, Lenovo's own design arm, and the number is printed on the PCB along with its revision, which should be checked before use. The 2.70 MB PDF lets a technician trace the power rails from the adapter input through the charger and system regulators, follow signals to the EC and connectors, and find the component causing a short or no-power condition. Note the G40-70 shipped on more than one board.
