Boardview for Lenovo board NM-B711, with R10 in the name read as revision 1.0, supplied as a ZIP of about 3.4 MB. LCFC, Lenovo's own ODM, uses this NM- numbering. A boardview lets a technician locate components, reference designators and test points, view which nets connect where, and quickly find parts around a shorted line. Extract it and open it in OpenBoardView, FlexBV or a similar tool, and pair it with the NM-B711 schematic for values and 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 @cidschematicandboardviewofficial. Enginerys does not host this file.
