Tested BIOS archive for the Dell Latitude 5480, made for the Compal LA-E081P motherboard at revision 2, labelled as tested by FST FIX. The 8.05 MB RAR should be unpacked and the image compared with your SPI chip before writing with a programmer such as a CH341A. Such dumps fix no-post, no-display and firmware corruption faults. Confirm the LA-E081P marking and revision on the PCB, and read and keep the original contents first, since they carry the service tag and board-specific settings.
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.
