Large 85.1 MB ZIP for the Dell Latitude E5440, Compal project VAW30, motherboard LA-9832P revision 1.0, with AOO in the name, which is not explained. The size suggests a collection, such as schematic, boardview or BIOS files, but the contents are not listed, so open the archive and check. Material like this helps with tracing power rails, locating components and restoring firmware. Compal uses the LA-xxxxP pattern, and the printed board number and revision should match LA-9832P before any data is relied on.
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 @azvoltagemap. Enginerys does not host this file.
