Boardview archive for the Lenovo IdeaPad S770-14 on LCFC board NM-E301, taken from the SVT build stage with a 0319 date code. LCFC is Lenovo's own ODM and uses the NM-xxxx numbering. A boardview maps component positions, nets and test points, so it speeds up finding a short or measuring a voltage rail. Unzip it and open the file in a viewer such as OpenBoardView or FlexBV. Pre-production SVT layouts can differ slightly from retail boards, so verify parts against the actual PCB.
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 @cynetitsolution. Enginerys does not host this file.
