Boardview for Inventec laptop board 6050A3348801, provided as a .CAD file in a 571 KB RAR archive. The name gives neither the laptop brand nor the model nor the assembly revision, so identify your board by the 6050A number printed on its PCB or sticker. Inventec uses this numbering for notebook mainboards it builds for brands such as HP and ASUS. CAD boardviews open in OpenBoardView, FlexBV and similar tools for tracing nets, locating parts and checking test points during short or power-rail diagnosis.
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 @BoardSchematic. Enginerys does not host this file.
