Schematic in PDF format for the Lenovo board NM-A471, numbered under the LCFC scheme used by Lenovo's in-house ODM. Neither the laptop model nor the revision appears in the name, so compare the board marking and layout before relying on component values. Technicians use such a diagram to trace power from the DC jack through the charger and regulators, read the power-on sequence and find which components to check when a rail is missing or shorted.
