RAR archive for the Dell Inspiron 3521 on Compal board LA-9104P, revision 1.0, labelled ok, which suggests the contents were reported as working. The name does not list the files inside, so expect a BIOS dump, schematic or similar repair material and check after extracting. Compal uses the LA-xxxxP pattern for its board numbers. If it is a firmware image, back up the original SPI chip with a programmer first and confirm the image size matches 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 @generalbios. Enginerys does not host this file.

How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
