Compal LA-F381P mainboard boardview in a fairly large 15.3 MB RAR archive, which may hold more than a single layout file. The name gives no brand, model or revision, so match the LA-F381P marking on the PCB before using it. Compal, a major notebook ODM, labels its boards with the LA- prefix regardless of the final laptop brand. Extract the archive and open the layout in a boardview program to locate components, follow nets, find test points and trace power rails while diagnosing no-power, no-charge or short-circuit faults.
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 @BoardSchematic. Enginerys does not host this file.
