PDF schematic for the Lenovo motherboard NM-D451. The board numbering follows the LCFC scheme, and other files in this collection link NM-D451 to the ThinkPad T14 Gen 2. The name itself states no model or revision, so compare the revision on the schematic title block with the board. Technicians use the diagram to trace power rails, the charger and EC circuitry, and signal routing during component-level repair. Any PDF viewer will open it.
