Compal motherboard LA-C611P, revision 1.0, with platform code A4WAS, supplied as a 6.53 MB ZIP archive. Compal uses the LA-xxxxP numbering for its laptop main boards, and the code before it is the internal project name. A package of this size usually holds a schematic PDF and possibly a boardview, though the name does not list the contents. Use it to trace power rails, check the power-on sequence and locate components, after matching the LA number and revision silkscreened on the PCB.
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.
