Reseat or Replace the Internal Webcam and Microphone Ribbon Cable

Safety Precautions: Power off the laptop completely, disconnect the AC adapter, and ensure you are working on a static-free surface. Use a plastic prying tool to avoid damaging the laptop chassis.

1. Carefully remove the display bezel or the bottom chassis cover according to the official HP Maintenance and Service Guide for the 15s-fq series to access the internal display cable routing.
2. Locate the ribbon cable that connects the webcam/microphone module to the motherboard, typically found near the display hinges.
3. Inspect the cable for signs of pinching, fraying, or oxidation at the connector pins.
4. Disconnect the ribbon cable from the ZIF (Zero Insertion Force) connector on the motherboard and the webcam module, then firmly reseat it to ensure a secure, flush connection.
5. If the cable shows physical damage, replace it with an identical OEM replacement part specific to the 15s-fq model.
6. Reassemble the laptop components and reconnect the power.
7. Verification: Power on the laptop, enter the BIOS/UEFI (Esc then F2 at startup), and run the 'Webcam' and 'Microphone' component tests. The fix is successful if the test reports 'Passed' and the devices remain detected during physical movement of the display lid.
