Lenovo notebook boardview for the LCFC mainboard NM-E091, revision 1.0, compressed into a 1.39 MB RAR archive. NM- numbers are used by LCFC, the Lenovo ODM that designs many IdeaPad, Legion and ThinkPad boards; the specific laptop model is not named here. Confirm the NM-E091 code and revision on the PCB before relying on part placement. In OpenBoardView, FlexBV or a similar tool, the file reveals component positions, nets and test points for tracing power rails and isolating shorts.
