PDF schematic, 1.95 MB, for the Lenovo ThinkBook 14p Gen 3 with mainboard NM-E561. NM- numbers come from LCFC, Lenovo's own design company. The drawings show power rail generation, enable and power-good chains, charger and EC wiring, so you can work out why a board stays dead or fails to boot. View it in any PDF reader and cross-reference reference designators with the boardview. Verify the board number and revision on the PCB before relying on values shown.
