NS-C223 boardview, a 265 KB .tvw file with no laptop model stated in its name. The NS-xxxx code matches the LCFC scheme used for Lenovo sub-boards, so this likely covers an auxiliary board rather than the main logic board, though the name does not confirm its function. Open it with a viewer that reads Tebo-ICT TVW files to inspect part placement, net connectivity and pad locations. Technicians use it to trace signals to the connector, check continuity and spot shorts; verify the NS-C223 marking 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 @pepeelectronica. Enginerys does not host this file.
