Boardview in .cad format for the Compal LA-M191P motherboard, project code HH4U4, revision 1B, about 867 KB. LA- numbers are Compal designations, so this board was built by Compal for a brand that the file name does not identify. The .cad layout opens in tools such as OpenBoardView, FlexBV or Boardviewer, showing part locations, pins and nets for locating test points and tracing shorts. Check that the board code and r1B revision on the PCB match before relying on placements.
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 @nityatechnology2020. Enginerys does not host this file.
