BIOS firmware for the Dell Latitude E5480 built on Compal board LA-E082P revision 1.0, with the platform code CDM70, A00 marking and a date of 2016-11-18 in the name. The 8.21 MB RAR archive likely holds an image for the SPI flash chip, which a technician writes with a programmer to recover a dead or locked board. Since the LA- numbering is Compal design, the board code silkscreened on the PCB should match. Back up the original chip and confirm the image size equals the chip 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 @biosarchive. Enginerys does not host this file.
