Boardview for the LCFC-designed NM-D451 mainboard used in Lenovo laptops, a 392 KB RAR archive; the name lists no specific model or file format beyond boardview and a PDF mention. A boardview shows the physical placement of every part and lets you click a net to see all connected pins, which speeds up finding test points and shorted components. Pair it with the matching NM-D451 schematic for best results. Open it in a viewer such as OpenBoardView or FlexBoardView and check the board number on the PCB first.
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 @schematicslaptop. Enginerys does not host this file.
