OEM-documented procedure; not bench-tested.\n\nReplace the combined speaker assembly including its cable, with the system board and battery pack installed.\n\nAuthorized service provider only for target/internal board-level assembly access; a CSR cover chapter does not make this target CSR. [HP printed 48, PDF 58](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=58)\n\n## Parts, configuration and tools\n\nL62736-001 is the model-specific speaker assembly including cable. No separate driver substitution is specified. [HP printed 58, PDF 68](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\nExact 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.

Role: target assembly. [HP printed 58, PDF 68](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\n## Source findings and boundaries\n\nThe 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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\nThe 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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\nThe 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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\n## Ordered replacement procedure\n\n1. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=47); [HP printed 34, PDF 44](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=44); [HP printed 35, PDF 45](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=45)\n\n2. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=47); [HP printed 38, PDF 48](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=48)\n\n3. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=59); [HP printed 58, PDF 68](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\n4. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68); [HP printed 32, PDF 42](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=42)\n\n5. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\n6. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\n7. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68); [HP printed 32, PDF 42](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=42)\n\n8. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=59); [HP printed 50, PDF 60](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=60); [HP printed 58, PDF 68](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=68)\n\n9. **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](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=47); [HP printed 38, PDF 48](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=48)\n\n## Proposed checks and review limits\n\nUNPERFORMED 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.\n\nNo 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.\n"
