The HP fingerprint reader board 850116-001 is a replacement component for the fingerprint reader in the ZBook 17 G4 Mobile Workstation. HP’s service manual lists this part number for the board, making it useful when replacing that component in the documented workstation model.
The board connects to the system board by a fingerprint-reader ribbon cable with a ZIF connector. The manual lists the reader-board bracket separately as part of a bracket kit, so the board and bracket are distinct service parts.
