We have not performed this repair; keep HP's manual open for its illustrations. Scope restrictions below are part of the guide: do not apply it to other models, generations or configurations. Service manuals are written for trained technicians; work at your own risk.

Applies to

HP EliteBook 840 G6. Confirm the exact model on the service label before starting.

Replace the combined speaker assembly including its cable, with the system board and battery pack installed.

Parts, configuration and tools

L62736-001 is the model-specific speaker assembly including cable. No separate driver substitution is specified. HP printed 58, PDF 68

Exact HP EliteBook 840 G6; confirm service label, original assembly and connector/routing configuration before selection. Manual spare is evidence for this model, not serial-specific fit approval. Other generations, visually similar parts and unlisted regional/configuration substitutions; no live availability or replacement supersession verified. HP printed 58, PDF 68

Magnetic Phillips P1; nonconductive, nonmarking pry tool; grounded ESD workstation and strap HP printed 32, PDF 42

Source findings and boundaries

The speaker prerequisite is battery-cable disconnection only. Battery pack screws, WLAN/WWAN terminals, display, keyboard, fan, heat sink and system board are not removals in this route. Basis: OEM text; diagram where applicable. HP printed 58, PDF 68

The illustrated long assembly is removed as one service unit; do not split its drivers or substitute a connector/polarity scheme. Basis: OEM text; diagram where applicable. HP printed 58, PDF 68

The thermal interface stays closed throughout the documented speaker route; no thermal-material renewal step is triggered. Basis: OEM text; diagram where applicable. HP printed 58, PDF 68

Ordered replacement procedure

  1. prepare — Save work and shut down through the operating system; resolve uncertainty about hibernation by starting and shutting down normally. Disconnect AC power and all external devices. Work on a flat, grounded ESD-protected surface with a wrist strap connected to the grounded work surface; avoid pins and circuitry. Keep removed parts and screws organized. Basis: OEM shutdown and ESD precautions; editorial organization join. HP printed 37, PDF 47; HP printed 34, PDF 44; HP printed 35, PDF 45
  2. access — Turn the computer upside down. Loosen five captive screws and three inset captive screws (eight total). Start under the display at the upper-left corner, pry the cover free and lift it off. Basis: OEM procedure paraphrased. HP printed 37, PDF 47; HP printed 38, PDF 48
  3. isolate — Disconnect the battery cable at the system-board connector. Leave the battery pack and its retention screws in place: the speaker procedure calls for cable isolation, not pack removal. Keep AC disconnected. Basis: OEM procedure paraphrased. HP printed 49, PDF 59; HP printed 58, PDF 68
  4. disconnect — Disconnect the speaker cable at the system board, handling the connector rather than pulling its wires. Free the cable from its retaining clip (figure callouts 1 and 2); retain its original path for installation. Basis: OEM procedure paraphrased. HP printed 58, PDF 68; HP printed 32, PDF 42
  5. remove — Remove the two broadhead Phillips M2.0 × 2.0 screws securing the assembly (callout 3). Lift the complete speaker assembly out at callout 4, keeping its cable clear. Basis: OEM procedure paraphrased. HP printed 58, PDF 68
  6. install — Seat the matching L62736-001 assembly in its original position. Reinstall the same two broadhead Phillips M2.0 × 2.0 screws in their original holes. The manual gives no torque value; none is supplied here. Basis: OEM reverse-install instruction expanded; no invented torque. HP printed 58, PDF 68
  7. reconnect — Return the speaker cable to its original retaining clip and connect it to the system board. Check that the cable is seated and cannot be trapped by the cover. Basis: OEM reverse installation plus cable-placement precaution. HP printed 58, PDF 68; HP printed 32, PDF 42
  8. restore — With speaker retention and routing checked and no loose hardware inside, reconnect the battery cable to the system board. The battery pack has not moved. Basis: OEM reverse battery-cable isolation; editorial inspection join. HP printed 49, PDF 59; HP printed 50, PDF 60; HP printed 58, PDF 68
  9. close — Refit the bottom cover, engage its original edges and tighten the eight captive screws in their original positions. Reconnect external devices and AC only after the cover is secured. Basis: OEM reverse-cover instruction; editorial closed-unit restoration. HP printed 37, PDF 47; HP printed 38, PDF 48

Proposed checks and review limits

UNPERFORMED editorial check, only after full closure and safe restoration: use an ordinary low-volume stereo sample to check both speakers; a listening check does not establish aftermarket equivalence.

No physical work, live electrical probing, mains-adapter opening, shorting, parts purchase, production import, publication or deployment occurred. Partial/unsupported records are evidence notes, not safe executable instructions. OEM service classification and serial-specific fit still require reviewer attention.
