Lenovo boardview for the NM-B391 motherboard, revision R10, in TVW format inside a 2.19 MB RAR archive. The NM- prefix points to LCFC, Lenovo's own board designer. Open the TVW in Teboview or a compatible boardview program to find components by reference, follow nets across layers, and locate test points for measuring rails or hunting a short. Check the board number and revision on the PCB before trusting placements, and use the matching schematic alongside it for circuit logic.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @schematicslaptop. Enginerys does not host this file.
