RAR package of 5.92 MB for the Compal LA-9981P board, revision R10 (1.0), named without a hyphen in the board code. The contents are not stated. The size suggests schematic material, possibly together with a boardview. It differs from the smaller LA-9981P archive. Compal uses this LA numbering for ODM notebook boards. Extract it to trace power rails and signals or locate parts, after checking that the number and revision on the PCB match.
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 @cyberlanelectonik. Enginerys does not host this file.
