Full circuit schematic in PDF for the Lenovo ThinkPad P14s on the NM-C931 mainboard, a number following the LCFC scheme used by Lenovo's in-house ODM. The document covers power sequencing, regulator circuits, connectors and signal routing, which a technician needs when diagnosing no-power, no-charge or no-display faults. Search net names in a PDF viewer to jump between pages. Confirm NM-C931 is printed on your PCB, since similar ThinkPad models use different LCFC boards.
