Firmware package for the HP ZBook 15u G3 Mobile Workstation, labelled with BID N75 and version 01.05. N75 is HP's BIOS family identifier, which helps match the file against the system board and avoid flashing code meant for another family. No board number or flash chip size appears in the name, so open the RAR and check the image size against the SPI chip on the board. Back up the existing contents with a programmer before writing, and confirm the platform after a reflash by checking that the machine boots and charges normally.
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 →
