Schematic in PDF for the Lenovo ThinkPad E590 motherboard NM-B911, packed in a 5.10 MB RAR. NM-xxxx numbers belong to LCFC, Lenovo's own design and manufacturing arm. The diagrams help trace the power-on sequence, charging circuit, rails and signals between the chipset, memory and connectors during board-level repair. Open it in any PDF reader and pair it with a boardview if available. Make sure the NM-B911 marking on the PCB matches before using component values.
