Boardview for the Compal LA-7321P mainboard, a 7.48 MB zip that the name tags as BRD and VIW, meaning it likely contains both a BRD layout and a VIW-type view file. Compal LA-numbered boards are built for several notebook brands. Open the BRD in OpenBoardView, FlexBV or a similar viewer to find components, pin nets and test points when tracing shorts or absent voltages. Make sure the PCB silkscreen reads LA-7321P and that the revision matches before relying on part positions.
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 @ITHINKHS. Enginerys does not host this file.
