RAR archive of 6.21 MB relating to the Compal mainboard LA-C811P; the name does not list what is inside, so it may hold BIOS dumps, a schematic, boardview or a mix. The LA-xxxxP code is Compal numbering and appears on boards supplied to several laptop brands. Extract it with WinRAR or 7-Zip and identify each file by extension before use. If it contains firmware, back up the original SPI chip first; for drawings, check that the board revision printed on the PCB matches the document.</p>
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_casediscussion. Enginerys does not host this file.
