Firmware image for the HP ProBook 4440s marked 3GN, packed as a 3.58 MB RAR. The meaning of the 3GN token is not stated and no board number is given, so compare the archive contents with the markings on your motherboard before use. Such dumps are flashed to the BIOS chip with an SPI programmer to recover a non-booting laptop. Read and store the original chip contents beforehand to keep serial data, and confirm the image size equals the installed flash 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.
