HP EliteBook 840 G10 firmware archive marked as LOCKED, compressed in RAR format at roughly 14.3 MB. The locked tag suggests the dump was read from a board that still carries a BIOS password or similar lock, so it likely represents the original state rather than a cleaned or unlocked image. Such a file is useful as a reference or backup, but probably not for removing a lock. Before any reflashing with an SPI programmer, back up the chip on your own board and verify chip capacity and image size agree.
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 @biosfilebins. Enginerys does not host this file.
