This guide covers replacing the NFC module in the HP EliteBook 840 G6 Notebook PC. HP's Table 6-10 on printed page 62 lists the spare part number for the module.

Tools and parts

  • Pry tool (non-conductive, non-marking), magnetic Phillips P1 screwdriver, and Torx T8 screwdriver.
  • Static-safe work surface
  • L14385-001 - NFC module (includes antenna and touchpad foam). Source: printed page 62.

Preparation

HP's preliminary requirements on printed page 32 set out the tools needed for removal and replacement work along with the service cautions that go with them. Follow the preparation steps on printed page 37: shut the computer down, pull the power cord out of the machine, and detach external devices; the bottom cover procedure on printed page 37 comes after that. Removed subassemblies and their screws belong away from the work area, plastic parts should not be forced, and cables are handled by their connectors and routed clear of the parts being lifted out (printed page 32). The module is held down by adhesive, so the battery on printed page 49 has to come out of the machine before the module can be released.

Replacement

  1. Get the computer ready for disassembly before any cover is lifted (printed page 39).
  2. Detach every external device from the computer (printed page 62).
  3. Take the bottom cover off the chassis so the interior is exposed (printed page 62).
  4. Take the battery out (printed page 62).
  5. Pull the system board cable and the NFC antenna off the ZIF connectors on the NFC module (printed page 62).
  6. Work the module free of the adhesive that holds it to the computer and lift it out (printed page 62).
  7. Install the NFC module by reversing the removal steps (printed page 62).
