A 2-in-1 laptop's webcam is detected and works normally while the lid is opened only a few centimeters, but Windows immediately shows "No camera found" when the lid is raised to a wider angle. An external USB webcam functions without issue. Which action is the MOST appropriate permanent fix for the built-in camera?
Disable USB selective suspend in the operating-system power plan.
Clean the webcam lens and bezel with a lint-free microfiber cloth.
Install the latest webcam driver from the laptop manufacturer.
Reseat or replace the webcam ribbon cable where it travels through the hinge.
Because the integrated webcam's flex-ribbon passes through the display hinge, years of opening and closing can loosen or fracture the cable or its ZIF (zero-insertion-force) connector. Movement of the lid then interrupts the data lines, causing the device to disappear from Device Manager. Reseating-or if damaged, replacing-the webcam ribbon where it routes through the hinge restores a stable hardware connection. Updating drivers or changing power-saving settings would not correct a physical open in the cable, and cleaning the lens only affects image quality, not device detection.
