 "markdown": "# HP EliteBook 840 G6 fingerprint reader assembly replacement\n\nSource: https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf (printed pages 39–69). OEM-documented procedure; not bench-tested.\n\nReplacing the fingerprint reader assembly on the HP EliteBook 840 G6 Notebook PC. HP lists the fingerprint reader spares in Table 6-14 on printed page 69 of the maintenance manual.\n\n## Tools and parts\n\n- Non-conductive, non-marking pry tool, magnetic Phillips P1 screwdriver, and Torx T8 screwdriver (HP tools required, printed page 32)\n- Static-safe work surface for the computer and for the parts you set aside\n- `L62741-001` - Fingerprint reader assembly (includes cable). Source: printed page 69.\n- `L62737-001` - Fingerprint reader bracket (included in Bracket Kit). Source: printed page 69.\n\n> You will need the following tools to complete the removal and replacement procedures: ● Non-conductive, non-marking pry tool ● Magnetic Phillips P1 screwdriver ● Torx T8 screwdriver\n\n## Preparation\n\nHP sets out its preliminary safety rules on printed page 32: the tools the job needs, the instruction to keep every removed subassembly and its screws clear of the work area, the warning that excessive force can damage plastic parts, and the requirement that cables sit in their proper routing during reassembly. The preparation steps printed on page 37 ask you to shut the computer down, unplug the power cord, and disconnect every external device. This procedure runs deeper than that: HP removes the bottom cover, the battery (procedure on printed page 49), and the system board (procedure on printed page 66) before it reaches the fingerprint reader assembly.\n\n## Replacement\n\n1. Prepare the computer for disassembly: shut it down, unplug the power cord, and disconnect external devices (printed pages 39, 37, 37, and 37).\n2. Remove the bottom cover to open the chassis (printed page 39).\n3. Take the battery out (printed page 59).\n4. Take the system board out (printed page 69).\n5. Back out the Phillips M2.0 × 3.0 screw (1) holding the fingerprint reader bracket to the computer (printed page 69).\n6. Lift the bracket away from the fingerprint reader assembly (2) (printed page 69).\n7. Pry the fingerprint reader board loose with a tool (3) and take the assembly out of the computer (4) (printed pages 69, and 55).\n8. Install the fingerprint reader assembly by reversing the removal steps (printed page 69).\n",
