Schematic diagram in PDF for the Lenovo ThinkPad E14 Gen 4 AMD, motherboard NM-E501. The NM- prefix marks a board designed by LCFC, Lenovo's own ODM. Any PDF reader will open it, and the diagram is used to follow power rails, the EC power-on sequence, charger circuitry and signal paths between components. Pair it with the matching NM-E501 boardview to find parts physically on the board. Check that the board revision on the PCB matches the schematic's revision page.
