 "markdown": "# HP EliteBook 840 G6 display/lid assembly removal and installation (intact lid)\n\nSource: https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf (printed pages 32–38, 41–44, 49–50, 70–71, 79). OEM-documented procedure; not bench-tested.\n\nScope: Intact lid detached at chassis hinge mounts and base connectors, then installed intact. Panel, bezel, cameras/sensors, antennas, internal lid wiring and lid-side hinges stay assembled. No construction of a complete lid from separate spare subcomponents.\n\nService classification: Authorized Service Provider (ASP): HP restricts chapter access to authorized providers; damage/warranty consequences apply. [HP printed 48 / PDF 58](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=58)\n\n## Configuration and spare scope\n\n- Confirm exact model, touch/non-touch, privacy/brightness/resolution, camera/IR/microphone/ambient-sensor and WLAN/WWAN configuration before selecting hardware.\n- Like-for-like service only; no touch, resolution, privacy, radio, camera or graphics conversion is established.\n- Preserve original connector identities and cable routes; stop on a mismatch.\n- Excluded: Bare glass/digitizer separation, bonded-layer rebuilding and generic aftermarket compatibility.\n\n[HP printed 25 / PDF 35](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=35); [HP printed 26 / PDF 36](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=36); [HP printed 70 / PDF 80](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=80); [HP printed 76 / PDF 86](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=86)\n\nManual explicitly supplies subcomponents only, not a whole display assembly. This is a complete mechanical detach/install route for an intact serviced lid or separately verified like-for-like unit; no OEM full-lid kit number or subpart-build procedure is claimed. [HP printed 25 / PDF 35](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=35); [HP printed 26 / PDF 36](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=36); [HP printed 70 / PDF 80](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=80)\n\nA manual table entry does not establish serial-specific fit, current availability, a shopping recommendation or an upgrade. Do not substitute a subcomponent number for a complete lid.\n\n## Tools and materials\n\n- Nonconductive nonmarking case tool\n- ESD equipment and screw organizer\n- Phillips P1 driver\n\n## What the manual establishes\n\n- DOCUMENTED: Only complete-lid chassis detachment/install is covered. The later bezel, camera, sensor, panel, lid-side hinge and antenna-peeling steps are conditional subcomponent work and are not prerequisites for keeping the lid intact. [HP printed 70 / PDF 80](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=80); [HP printed 71 / PDF 81](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=81)\n\n## Ordered procedure\n\nDOCUMENTED steps are original-language paraphrases. Reassembly expands HP reverse directions. PROPOSED marks editorial joins/support precautions; it is not bench verification. No generic latch direction, temperature, solvent, force, torque or tightening pattern is invented.\n\n1. **Prepare.** Confirm the model and the variant gate above. Save work and shut down through the operating system; if uncertain about sleep/hibernation, wake then shut down. Disconnect external devices. Unplug AC from the outlet and computer before opening. Use a clean ESD-protected workspace, grounded handling and sorted original screw locations. Handle cables by connectors, avoid bending/twisting flex cables and do not use sharp tools on the battery.

Loosen five ordinary captive screws and three inset captive screws. Start under the display at the upper-left corner; release and lift off the cover. Captive screws stay with the cover; retain all original positions. (DOCUMENTED paraphrase) [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 from the system board by its connector, not by pulling wires. Leave the battery physically secured; the display section requires disconnection, not pack removal. (DOCUMENTED paraphrase) [HP printed 49 / PDF 59](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=59)\n\n4. **Disconnect.** Record the original antenna terminal identities and cable paths. Disconnect the WWAN antenna leads only if that module is fitted, then the fitted WLAN antenna leads by their connector ends. Keep the radio modules installed. Release antenna leads from the chassis clips. Protect any unused/unconnected antenna connector with the OEM protective sleeve; do not fit an unsupported extra antenna.

Release them from their chassis retaining clips. Keep every lead free of the hinge-removal path; handle connectors without guessing an unprovided latch motion. (DOCUMENTED paraphrase) [HP printed 70 / PDF 80](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=80)\n\n6. **Remove.** With the computer upside down, open the display and position it off the table edge as illustrated. Support the base and lid so neither falls or loads the cables. Remove the five Phillips M2.5 x 5.0 hinge-to-base screws from their original groups. Lift the intact display straight up, free of the chassis; do not strip the lid internals. (DOCUMENTED hinge orientation/fasteners/removal; supported handling is a PROPOSED editorial safeguard) [HP printed 70 / PDF 80](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=80); [HP printed 71 / PDF 81](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=81)\n\n7. **Install.** Keeping the serviced/replacement lid intact and its leads clear, align the original hinge-to-base mounts in the reverse illustrated orientation. Support the lid and restore the five Phillips M2.5 x 5.0 screws in their original holes. No numeric torque or new tightening order is established. (DOCUMENTED reverse-procedure direction) [HP printed 70 / PDF 80](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=80); [HP printed 71 / PDF 81](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=81); [HP printed 79 / PDF 89](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=89)\n\n8. **Reconnect.** Restore the camera and display connections and their original chassis paths/clips. Restore the wireless antenna routes exactly; HP warns incorrect routing can degrade wireless performance. Reconnect only fitted radio leads: WLAN lead 1 to Main 1 and lead 2 to Aux 2 when those labels/configuration apply; WWAN red to Main and blue to Aux. Preserve the recorded actual mapping for other fitted variants; do not invent a terminal or connect a lead by color alone when labels differ. Keep cables clear of hinges and cover. (DOCUMENTED routing warning and radio notes; combined reconnection order PROPOSED) [HP printed 70 / PDF 80](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=80); [HP printed 71 / PDF 81](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=81); [HP printed 41 / PDF 51](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=51); [HP printed 43 / PDF 53](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=53); [HP printed 79 / PDF 89](https://kaas.hpcloud.hp.com/pdf-public/pdf_12664225_en-US-1.pdf#page=89)\n\n9. **Restore.** With hinges secured, display/camera/antenna leads seated and all routing checks complete, reconnect the battery cable. Check that the cable cannot be pinched by the cover. (PROPOSED combined reassembly order from OEM reverse directions) [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)\n\n10. **Close.** Check for tools/loose screws and trapped cables. Refit and seat the bottom cover and its clips; restore five ordinary captive screws and three inset captive screws to their original holes. Do not introduce an unprovided torque or tightening sequence. (DOCUMENTED reverse-procedure direction; combined order PROPOSED) [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 - unperformed\n\n- UNPERFORMED / PROPOSED: after full reassembly and gate resolution, power on and check image/backlight, ordinary lid motion without pinching, and startup errors.\n- UNPERFORMED / PROPOSED: check fitted camera, microphones, IR sign-in, ambient sensor, privacy feature and touch only where originally equipped; check WLAN and WWAN behavior on equipped configurations. These checks do not prove electrical upgrade compatibility or calibrated RF performance. Stop for flicker, binding, abnormal heat or damaged cables; shut down and isolate power before reopening.\n"
