RAR archive, 219 KB, for the Compal LA-3732P notebook mainboard. The name does not state model, revision or contents. The small size hints at a boardview or firmware image rather than a full schematic. LA-xxxxP is Compal's ODM board numbering, used on notebooks of several brands. After extracting, open a boardview in a viewer, or treat a binary as a dump. Back up the existing SPI chip before flashing, and check the image size against the flash capacity.
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.
