Fix laptop built-in webcam not working or missing in Device Manager

The essential answer

If the laptop’s built-in webcam is missing from Device Manager, Windows has not enumerated it as a present camera. That is a device-detection problem. It is separate from an app being denied camera permission, from the wrong camera being selected in a meeting tool, and from a camera that is listed but shows a black or frozen image.

What you do next depends on what Device Manager actually shows. If the camera is listed under Cameras or Imaging devices with no error, detection succeeded and the remaining issue is permission, input selection, or the application. If it is listed but disabled or marked with a warning, Windows sees the hardware and the device state or driver needs attention. If it is absent even after hidden devices are shown, Windows is not being told the camera exists. Typical reasons are a hardware privacy switch, a firmware or UEFI disable, a driver that never loaded, or a hardware fault. Device Manager is a Windows tool, so these steps apply to Windows 10 and Windows 11. They do not diagnose macOS or ChromeOS cameras, and they do not, by themselves, diagnose the built-in microphone.

Checks that narrow the cause

Use only the layers that can hide a built-in camera from Windows. Each result supports a conclusion about that layer alone. A working app preview does not prove Device Manager is healthy, a missing camera entry does not prove the microphone is broken, and turning camera permission on cannot create a device Windows has not enumerated.

• Confirm you are inspecting the webcam, not the microphone. In Device Manager, the built-in camera usually appears under Cameras or Imaging devices. The built-in microphone appears under Audio inputs and outputs or Sound, video and game controllers. Finding or missing a microphone entry says nothing about whether the webcam is present.
• Look at the chassis for a sliding privacy shutter, a dedicated camera kill switch, or a function-key camera toggle. An open shutter only tells you the lens is uncovered. Many shutters leave the camera listed in Device Manager and simply block light, so a black image with the device still listed points at the shutter, not at missing hardware. On some models a hardware disconnect switch or function-key disable can remove the camera from the list. This check does not test drivers, UEFI, or app permissions.
• In Device Manager, turn on View then Show hidden devices, and expand Cameras, Imaging devices, and Other devices. A hidden or disabled camera, often with a down-arrow overlay, means Windows has a record of the device but it is turned off in software. An unknown device or a yellow warning means hardware was reported without a working driver. An empty camera category after hidden devices are shown means Windows did not enumerate a camera. Scan for hardware changes only tests whether Windows can rediscover devices on the current bus; it does not prove the sensor works.
• Open Windows camera privacy settings: Settings, then Privacy or Privacy & security, then Camera. The switch that lets apps access the camera, and the per-app toggles, control whether applications may use a camera Windows already sees. They do not add a missing device to Device Manager. If access is off, apps can fail even when the camera is listed.
• Open the Windows Camera app, if it is installed, and look for a live preview. A working preview supports that detection, the driver, and OS access are sufficient for that app. Failure in Camera while Device Manager lists the device points to permission, another app holding exclusive access, or an app-specific fault. If Camera reports that no camera is found, that is consistent with a detection problem; it does not identify whether the cause is a switch, UEFI, driver, or hardware.
• If the PC maker documents an internal-camera or imaging option in UEFI/BIOS setup, check that the built-in camera is enabled, then boot Windows and recheck Device Manager. A firmware disable can prevent enumeration. This check only tests firmware policy. It does not repair a failed module, and the key used to enter setup is model-specific—use the method the laptop maker documents for your machine.

Match the finding to the next step

Finding	What it supports	What to change next
Camera listed, no warning, preview works in Camera	Detection and the inbox capture path are working	Fix the app: permission, input selection, or exclusive use by another program
Camera listed, image is black, shutter can close over the lens	The device is enumerated; light may be blocked	Open the shutter, then retest the same app
Camera listed but disabled	Windows knows the device and it is turned off in software	Enable the device in Device Manager, then retest
Unknown device or camera with a warning	Hardware was reported; the driver or device state is not healthy	Use the laptop maker’s documented camera or chipset driver for this model
Camera absent, even with hidden devices shown	Windows is not enumerating a camera	Check the hardware camera switch, then UEFI camera enable if that option exists
Windows camera access is off	Apps are blocked; Device Manager is not explained by this switch	Turn access on only after the camera is listed
Microphone is missing or failing	Audio capture, not webcam video	Treat that as a separate input; do not use it as proof about the camera

What to change, and how you know it worked

Start with reversible changes. After each one, return to Device Manager with hidden devices shown and retest the original symptom. Success for a missing-camera case is the built-in webcam appearing under Cameras or Imaging devices without a warning, plus a live image in the same app that failed. Success for a listed camera that would not capture is that live image, with the Device Manager entry unchanged.

• If a shutter is closed, open it fully. Retest in the app you care about. The Device Manager entry may already have been present.
• If you used a camera function key or a hardware camera switch, set it to enable the camera, then refresh Device Manager or restart. Success is the camera node appearing, or changing from disabled to enabled, and a live preview.
• If the camera is listed but disabled, enable it from the device’s context menu or Properties. Success is the disabled overlay clearing and a live preview.
• If Device Manager already lists the camera and apps still cannot use it, turn on Windows camera access for desktop apps and for the specific app, then close other capture apps and retest. This will not create a missing Device Manager entry.
• If Device Manager shows an unknown imaging device or a camera with a warning, a driver change may be required. Official driver, firmware, and recovery steps are published by the laptop manufacturer for the exact model and Windows version, and this article does not include a verified OEM procedure. Use the camera or chipset package the maker documents for that model. An unmatched generic installer can leave the camera missing or in a warning state, and can remove OEM features that depend on the maker’s driver, including some camera effects and Windows Hello face sign-in. A driver rollback is available only if Windows still has the previous driver. A firmware update is not trivially reversible and can leave the system unable to boot if it is interrupted, so apply firmware only when the maker’s instructions for your model call for it.
• If the camera is absent and UEFI lists an internal-camera disable option, enable it, save, boot Windows, and recheck Device Manager. Success is enumeration of the camera. Skip undocumented firmware resets.
• Do not use a full Windows reset as a first webcam fix. A reset reinstalls Windows components and can remove apps and, depending on the option you choose, personal files. It will not restore a camera that firmware is holding disabled or that has failed in hardware.

When to stop

If the camera is still missing after the shutter or hardware switch is in the capture position, hidden devices are shown, Windows camera access is on, UEFI has the internal camera enabled when that option exists, and you have followed the manufacturer’s documented driver steps for your model, stop repeating the same Device Manager refresh. The remaining causes are hardware: a disconnected internal cable, a failed camera module, or a mainboard issue. Those need the PC maker’s support or a repair service. Further permission toggles will not enumerate a device the firmware is not presenting.
