BIOS and EC firmware package for the HP ZBook 15 G3 mobile workstation built on Compal board LA-C381P, packed as an 11.6 MB RAR archive credited to Luirons Bios. Compal uses the LA-xxxxP numbering for its motherboard designs, and that code should match the label on the PCB. Expect separate images for the system SPI flash and the embedded controller, written with a programmer such as a CH341A. Read and save the original chip contents before flashing, and check each image size against the chip capacity.
