Boardview for LCFC board NM-F511, a Lenovo mainboard, archived at 6.23 MB. The name gives no revision or laptop model, so confirm the NM code silkscreened on the PCB before relying on part positions. LCFC, Lenovo's in-house ODM, uses the NM-xxxx pattern for its designs. Technicians use such layouts to locate components by reference, follow nets across both board sides and find test points when measuring power rails or chasing shorts. Programs such as FlexBV and OpenBoardView open the common formats.
