Boardview in CAD format for a laptop motherboard built on Compal board LA-9982P; the name gives no laptop brand, model or revision. Compal uses the LA-xxxxP numbering for its ODM boards, which are sold under many brands. A .cad boardview opens in viewers such as OpenBoardView, FlexBV or Boardviewer and lets you locate components, test points and nets while tracing power rails or hunting a short. Confirm that the LA-9982P marking and revision silkscreened on the PCB match before trusting 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 @afssolutions. Enginerys does not host this file.
