Firmware package labelled for the HP ProBook 455 G1, compressed as a 2.62 MB ZIP. The name gives only the model and states no board number, chip type or version, so open the archive and check what image it actually contains before use. Such dumps are normally written to the laptop's SPI BIOS chip with a programmer such as a CH341A to revive a board with corrupted firmware. Read and keep the original contents first, and make sure the image size matches the capacity of the flash chip fitted.
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.
How to open a .zip file
