How to Fix a Camera Not Working

Follow these steps, in the order, to troubleshoot your webcam and get it working again.

Checking Camera Connection

If you're using an external USB webcam, the first step is to ensure that it's properly connected.

1. If you're using an external USB camera, ensure its securely connected to the USB port.
2. For cameras integrated to monitors, ensure the USB upstream cable is connected between the monitor and your computer.
3. Try a different USB port.
4. If the USB camera works on a different port, try to fix USB port problems.

If the camera doesn't work on a different port, proceed to the next step.

Checking Privacy Shutter

Many laptops and USB webcams come equipped with a privacy shutter that physically blocks the camera lens.

1. Locate the shutter or privacy cover on your webcam.
2. If you find one, make sure it's in the open position.
3. After adjusting the shutter, try using your webcam again.

If the camera issue persists, proceed to the next step.

Allowing Access to the Camera

Windows has privacy settings that may restrict apps from accessing your camera. Ensuring these settings are configured correctly is important for allowing apps to use your webcam.

1. Go to Start > Settings > Privacy > Camera.
2. Enable the option labeled Allow apps to access your camera.
3. Scroll down to the list of apps and make sure that the specific app you want to use (such as Teams, Zoom, Skype, etc.) has permission enabled.

If the camera still doesn't work, proceed to the next step.

Enabling the Camera in BIOS

For computers with built-in camera, it's important to ensure that the camera is enabled in the BIOS settings. If it's not, it may prevent the operating system from recognizing the hardware.

1. Restart your computer.
2. Press the F2 key repeatedly until the BIOS setup screen appears.
3. Locate the Enable Camera option under the Integrated Devices section.
4. Make sure the camera is enabled.
5. Save changes and exit the BIOS.

If the camera is enabled and the issue persists, proceed to the next step.

Testing Your Camera

Verifying that your webcam works using another app such as Windows' built-in Camera app helps determine if the issue is with the camera itself or specific apps.

1. Search for Camera in the Start menu and open the app.
2. Check if you get a video feed from your webcam.
3. If the webcam works, the issue may be limited to a specific app.

If the webcam doesn't work, proceed to the next step.

Checking for Windows Updates

Keeping your operating system updated ensures you have the latest features and fixes. To check for Windows updates:

1. Go to Start > Settings > Windows Update. Open Windows Update settings.
2. Select Check for updates and install the available updates.

Running the Camera Troubleshooter

The camera troubleshooter can automatically resolve camera issues.

1. Go to Start > Settings > System > Troubleshoot. Open Windows troubleshooter settings.
2. Select Other troubleshooters.
3. Locate the Camera section and click Run to start the troubleshooter.

If the troubleshooter can't resolve the issue, proceed to the next step.

Updating Drivers and BIOS

Outdated drivers and BIOS can often lead to functionality issues with hardware components like cameras. SupportAssist is Dell's automated tool that scans your Windows computer for driver and firmware updates, downloads, and installs them.

Using SupportAssist

1. Search for SupportAssist in the Start menu and open the app.
2. On the Home tab, select Update Software.
3. Click Start to check for driver and BIOS updates.
4. Follow the on-screen instructions to complete the installation and restart your computer if prompted.

If you don't have SupportAssist, refer to our driver update guide for alternative methods to download and install Dell drivers.
