RAR package for the Compal-designed motherboard LA-J371P, revision 1.0, with platform code FDZ41 named alongside. Compal uses the LA-xxxxP numbering for boards it builds for Dell, Acer, Lenovo and other brands, and the four- or five-letter code is its internal project name. At 8.89 MB the archive probably holds schematics and possibly a boardview; unpack it to check. Use it for tracing rails and signals, and match the LA-J371P number and revision on the PCB first.
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 @ShareMan_Electronic_Files. Enginerys does not host this file.
