Lenovo boardview for board NM-D821, revision 1.0, zipped at 6.07 MB. NM-xxxx numbers follow the LCFC scheme, the Lenovo-owned ODM that designs many of its laptop mainboards, and the name does not specify the laptop model. The file shows part placement, nets and test points for tracing power rails, signal paths and shorts. Open it with OpenBoardView, FlexBV or a similar tool, and confirm the NM-D821 number and revision on the PCB match before relying on component locations.
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 @cidschematicandboardviewofficial. Enginerys does not host this file.
