Firmware set for the HP ZBook 15 G3 mobile workstation built on the Compal LA-C381P motherboard, containing both the BIOS and the embedded controller (EC) image according to the name. The 11.6 MB RAR archive should be unpacked and each file matched to its own chip by capacity. LA- numbers follow the Compal pattern, so verify the full code and revision printed on the PCB. Dump and keep the original contents of both flash chips before programming, since the EC image controls power-on, charging and keyboard behaviour.
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 .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
