Schematic for the Lenovo ThinkPad L450 mainboard, LCFC board NM-A351 at revision 1.0, in a 2.19 MB PDF. LCFC, Lenovo's design house, numbers its boards in this NM- style, printed on the PCB for easy matching. Revision 1.0 typically corresponds to production hardware. Technicians use the document to trace power rails, follow the charger and EC circuits, find test points and identify parts around a short. Confirm the board revision before replacing components by value.
