Preparation
HP 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 and then the battery (HP's battery procedure is on printed page 49) before it reaches the card reader.
Replacement
- Prepare the computer for disassembly: shut it down, unplug the power cord, and disconnect external devices (printed pages 39, 37, 37, and 37).
- Remove the bottom cover to open the chassis (printed page 39).
- Take the battery out (printed page 59).
- Check that no memory card or plastic insert is left in the reader (printed pages 63, and 63).
- Pull the system board cable free of its connector on the smart card reader board (1) (printed page 63).
- Unplug the touchpad cable from the ZIF connector (2) mounted on the smart card reader board (printed page 63).
- Back out the three Phillips M2.0 × 2.0 screws (3) that hold the smart card reader to the computer (printed page 63).
- Lift the smart card reader out of the computer (4) (printed page 63).
- Install the smart card reader by reversing the removal steps (printed page 63).
