Lenovo boardview for the LCFC-designed NM-B451 motherboard, revision R02, in the UMA variant, meaning graphics run from the processor with no discrete GPU fitted. The TVW format opens in TeboView and similar boardview viewers, where you can click a part to see its nets and follow signals across layers. Technicians use it to locate components, test points and power rail nodes while chasing a short or a missing voltage. NM-B numbers follow the LCFC scheme, so confirm the board number and revision silkscreened on the PCB before trusting placements.
