OEM-documented procedure; not bench-tested.\n\nLike-for-like WLAN/Bluetooth module service, limited to the fitted OEM configuration. The executable route requires the two numbered antenna leads and Main 1/Aux 2 terminals documented here; it does not establish a one-lead or three-terminal variant.\n\nWLAN is in the Customer Self-Repair chapter, subject to local program and warranty eligibility. This is not universal permission; referenced battery/internal service restrictions still apply. [HP printed 36, PDF 46](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=46); [HP printed 47, PDF 57](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=57)\n\n## Assembly inventory and configuration\n\nAll listed WLAN service candidates from this manual are inventoried below. These are not an upgrade list or proof that alternatives share an electrical interface. Exact factory configuration and regional eligibility must be checked. [HP printed 22, PDF 32](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=32); [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50); [HP printed 41, PDF 51](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=51)\n\nExact HP ProBook 440 G6 and a verified like-for-like OEM assembly/configuration; preserve original routing and connector identity. Serial fit and regional eligibility remain unverified. Other models/generations, arbitrary substitutions and upgrades. No WWAN substitution, interface conversion or blanket regional-radio approval. Stop if fitted lead/terminal arrangement differs from the documented scope.

Role: documented WLAN service candidate; fit not universally verified. [HP printed 22, PDF 32](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=32); [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50)\n\n- **915621-001**: Realtek RTL8821CE, 802.11ac 1×1, Bluetooth 4.2. Role: documented WLAN service candidate; fit not universally verified.

Role: documented WLAN service candidate; fit not universally verified. [HP printed 22, PDF 32](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=32); [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50)\n\n## Documented facts and proposed boundaries\n\nThe target is WLAN/Bluetooth, not WWAN. Antenna lead count, electrical interface, vPro option and exact spare suffix remain configuration limits; slot shape and radio marketing names alone do not establish interchangeable modules. Basis: DOCUMENTED option inventory; PROPOSED like-for-like scope restriction. [HP printed 22, PDF 32](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=32); [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50)\n\nThe illustrated WLAN removal uses antenna connectors (callout 1), one retaining screw (callout 2) and module withdrawal from its socket at an angle (callout 3). Reinstallation reverses that sequence. No connector latch travel, removal angle in degrees or torque is specified. Basis: DOCUMENTED OEM text and applicable figure. [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50); [HP printed 41, PDF 51](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=51)\n\nProtective sleeves are required on WLAN antenna connectors left unconnected to module terminals. Original labels/routing may be recorded as an editorial precaution, but that does not resolve contradictory OEM terminal evidence. Basis: DOCUMENTED sleeve requirement; PROPOSED original-configuration recording precaution. [HP printed 41, PDF 51](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=51)\n\nThe product table lists Realtek PCIe/USB variants and Intel 9560 CNViL separately. It also mentions three WLAN antennas while the illustrated procedure has two leads, plus a conditional legacy yellow/middle-terminal note. This guide is explicitly restricted to the already fitted two-lead Main 1/Aux 2 arrangement. A one-lead, third-lead or differently labeled configuration is outside the executable route, not resolved by counting spatial streams. Basis: DOCUMENTED product/procedure variation; PROPOSED narrow complete scope. [HP printed 3, PDF 13](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=13); [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50); [HP printed 41, PDF 51](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=51)\n\n## Ordered replacement procedure\n\n1. **prepare** - Save work and shut down through the operating system. If power/hibernation state is uncertain, start normally and then shut down. Disconnect external devices and AC power before opening. Use a flat ESD-protected grounded work surface with a grounded wrist strap; avoid pins and circuitry and keep screws organized. Basis: DOCUMENTED shutdown/ESD precautions; PROPOSED organization join. [HP printed 36, PDF 46](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=46); [HP printed 34, PDF 44](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=44)\n\n2. **safe-mode** - Before opening, place the off computer in Battery Safe mode with AC connected: press Windows + Backspace + Power, turn the computer on to initiate the mode, then disconnect AC after the computer powers off. In this mode Power alone will not start the unit without AC. Keep AC disconnected during internal work. Basis: DOCUMENTED OEM operation paraphrased. [HP printed 36, PDF 46](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=46)\n\n3. **access** - Remove the two Phillips M2.0 × 5.0 cover screws and loosen the five captive Phillips screws. Starting under the display, release the cover with the nonconductive, nonmarking tool, lift its rear to disengage it and remove it. Basis: DOCUMENTED OEM operation paraphrased. [HP printed 36, PDF 46](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=46); [HP printed 37, PDF 47](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=47)\n\n4. **isolate** - Remove the two Phillips M2.0 × 4.0 main-battery screws. Lift the top edge of the battery, use the nonconductive tool to release the retaining tab at its bottom-left corner, and lift the battery out. Physical removal is required in addition to Battery Safe mode; no separate wired disconnect is specified here. Basis: DOCUMENTED OEM operation paraphrased. [HP printed 38, PDF 48](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=48)\n\n5. **disconnect** - Before detaching anything, confirm that this fitted like-for-like WLAN module has the documented two-lead arrangement: cable 1 at Main terminal 1 and cable 2 at Aux terminal 2. Preserve their original routes and labels. Carefully disconnect the two antenna connectors at the module, handling the connectors with minimal necessary force rather than pulling the wires. If the arrangement differs, stop outside this guide’s supported scope. Basis: DOCUMENTED terminal assignments/handling; PROPOSED pre-removal configuration check. [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50); [HP printed 31, PDF 41](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=41)\n\n6. **remove** - Remove the single Phillips M2.0 × 2.5 WLAN retaining screw. The edge opposite the socket rises; withdraw the WLAN module from the socket at that angle. Keep the module notch/socket relationship identifiable and avoid its contacts. Basis: DOCUMENTED OEM operation paraphrased. [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50); [HP printed 41, PDF 51](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=51)\n\n7. **install** - Insert the verified like-for-like WLAN module into its original socket in the same notched orientation, reverse the withdrawal motion, lower the free edge and reinstall the single Phillips M2.0 × 2.5 screw. No torque value or numeric insertion angle is supplied. Basis: DOCUMENTED reverse-install instruction expanded. [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50); [HP printed 41, PDF 51](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=51)\n\n8. **reconnect** - Reconnect lead 1 to Main 1 and lead 2 to Aux 2, matching the confirmed fitted arrangement and original routing. Restore protective sleeves on any connector left unconnected as the manual requires. Check that leads are seated and cannot be snagged or pinched; do not apply the conditional yellow/middle-terminal note to an unidentified configuration. Basis: DOCUMENTED reverse connection, sleeve and cable-care instructions; PROPOSED routing inspection. [HP printed 40, PDF 50](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=50); [HP printed 41, PDF 51](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=51); [HP printed 31, PDF 41](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=41)\n\n9. **restore** - After checking the WLAN module, its retaining screw and all antenna connections/sleeves, reinstall the main battery by reversing its removal: return the pack to its original seat and retaining tab and reinstall the two Phillips M2.0 × 4.0 screws. Basis: DOCUMENTED reverse battery procedure; PROPOSED inspection join. [HP printed 38, PDF 48](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=48)\n\n10. **close** - Refit the bottom cover and its original edges, tighten the five captive Phillips screws and reinstall the two Phillips M2.0 × 5.0 cover screws. Only after closure, connect AC and press Power to disengage Battery Safe mode. Restore other external connections as needed. Basis: DOCUMENTED reverse-cover procedure; PROPOSED closed-unit restoration join. [HP printed 36, PDF 46](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=46); [HP printed 37, PDF 47](https://kaas.hpcloud.hp.com/pdf-public/pdf_13033544_en-US-1.pdf#page=47)\n\n## Proposed checks and limits\n\nUNPERFORMED PROPOSED editorial check after correct complete reassembly: use the existing operating-system device listing to observe WLAN/Bluetooth recognition; no new network connection or upgrade/performance claim is included.\n"
