Test your webcam in Windows or Mac before you troubleshoot
The fastest way to know whether your webcam works is to open the camera app that came with your operating system. On Windows 10 and 11, search for "Camera" in the Start menu and click the app — it will show your live video feed if the webcam is working. On Mac, open Launchpad, search for "Photo Booth," and click it; you'll see yourself on screen if the camera is functional. If you see a live image, your hardware is working. If you see a black screen or an error message, the problem is either a hardware issue, a driver problem, or a permission block in your system settings.
Before you assume the webcam is broken, check whether your laptop has a physical camera shutter or a software toggle. Some laptops have a small lever or button above the screen that physically covers the lens — slide or press it to uncover the camera. Others have a keyboard shortcut (often Fn plus a key with a camera icon) that disables the camera in software. Try toggling this shortcut, then test the camera app again.
Key Takeaways
- Open the Camera app (Windows) or Photo Booth (Mac) to see whether your webcam produces a live video feed right now.
- Check for a physical camera shutter above your screen or a keyboard shortcut that disables the camera, and toggle both before assuming hardware failure.
- If the camera app shows a black screen, go to your system settings and confirm that the camera has permission to access your webcam.
- Update your camera driver through Device Manager (Windows) or System Settings (Mac) if the camera app works but other programs cannot access the camera.
- Restart your laptop and close any other programs using the camera before testing in a video call or recording app.
Check camera permissions in your system settings
Many programs cannot access your webcam because Windows or Mac is blocking them. On Windows 10 and 11, open Settings, go to Privacy & Security, then Camera. You'll see a list of apps with toggles next to them. Make sure the Camera toggle at the top is turned on, then scroll down and turn on the toggle for any app you want to use the camera with (Zoom, Teams, Discord, your browser, and so on). If an app you need is not listed, it may not have requested camera permission yet — open that app, try to use the camera, and the permission request should appear.
On Mac, open System Settings, go to Privacy & Security, then Camera. You'll see a list of apps that have requested camera access. If an app is not listed and you want it to use the camera, you may need to grant permission manually. Click the lock icon at the bottom left, enter your password, then click the plus button and select the app from your Applications folder. Close System Settings and restart the app.
Update your camera driver on Windows
If the Camera app works but other programs show a black screen or say the camera is not found, your camera driver may be outdated or corrupted. Open Device Manager by right-clicking the Start button and selecting Device Manager (or search for "Device Manager" in the Start menu). Look for "Cameras" in the list and click the arrow next to it to expand the section.
Right-click your camera (it will have a name like "Integrated Camera" or your laptop brand's name) and select "Update driver." Choose "Search automatically for updated driver software" and let Windows search for and install the latest version. After the update finishes, restart your laptop and test the camera again in the app that was not working.
If Device Manager shows a yellow exclamation mark next to your camera, the driver is definitely broken. Right-click the camera, select "Uninstall device," restart your laptop, and Windows will automatically reinstall the driver. If the camera still does not work after reinstalling, visit your laptop manufacturer's support website, search for your model number, and read the camera driver from there.
Restart your laptop and close other camera apps
Only one program can use your webcam at a time on most laptops. If you have Zoom, Teams, Discord, or your browser open and you try to test the camera in another app, the second app will not be able to access it. Close all programs that might be using the camera, then test again. If you're not sure which programs are running, restart your laptop — this closes everything and gives you a clean start.
After restart, open only the Camera app (or Photo Booth on Mac) and test it. If it works, you know the hardware is fine. Then open the specific app you need to use the camera with (Zoom, Teams, etc.) and test the camera there. If it works in one app but not another, the problem is usually a permission setting or a driver issue specific to that app, not your webcam itself.
Test your microphone at the same time
Most laptop webcams have a built-in microphone, and it often stops working when the camera does. In the Camera app on Windows, look for a microphone icon or a settings button — some versions of the Camera app let you test audio from within the app itself. On Mac, Photo Booth does not test audio, so open System Preferences, go to Sound, and click the Input tab. You should see "Built-in Microphone" listed. Speak into your laptop and watch the input level meter — if it moves when you talk, the microphone is working.
If the microphone does not show input, check that it is not muted. Look for a mute button on your keyboard (usually marked with a microphone icon with a line through it) and press it to toggle mute off. Also check your system settings: on Windows, go to Settings > Privacy & Security > Microphone and make sure the microphone toggle is on. On Mac, go to System Settings > Privacy & Security > Microphone and check that your apps have permission.
Test the camera in a video call app
The real test is whether your camera works in the app you actually need it for. Open Zoom, Microsoft Teams, Google Meet, Discord, or whatever program you use, and look for a settings or preferences menu. Most video call apps have a camera preview or test feature before you join a call. In Zoom, click your profile picture, go to Settings, click Video, and you should see a preview of your camera. In Teams, click your profile picture, go to Settings, click Devices, and look for Camera. In Google Meet, start a new meeting and you'll see a preview before you turn on your camera.
If you see yourself in the preview, the camera works in that app. If you see a black screen or an error, go back to your system settings and check that the app has camera permission. If permission is already granted, try closing the app completely, restarting your laptop, and opening the app again. If the camera still does not work in that specific app after restart, uninstall and reinstall the app — sometimes the installation gets corrupted and a fresh install fixes it.
When to contact your laptop manufacturer or a technician
If the Camera app shows a live feed but other programs cannot access the camera, the problem is almost always a driver or permission issue, and the steps above will fix it. But if the Camera app itself shows a black screen, an error message, or nothing at all, the webcam hardware may be broken or disconnected inside your laptop. This is not something you can fix yourself without opening the laptop.
Contact your laptop manufacturer's support line or visit an authorized repair shop. Have ready the model number of your laptop (usually on a sticker on the bottom), the operating system version (Windows 10, Windows 11, macOS Ventura, etc.), and a description of what you see when you open the Camera app. If your laptop is still under warranty, the repair may be free or low-cost. If it is out of warranty, ask for a repair estimate before they begin work.
Frequently Asked Questions
Why does my camera work in the Camera app but not in Zoom?
Zoom does not have permission to use your camera. Open your system settings, go to Privacy & Security, click Camera, and turn on the toggle next to Zoom. Then close Zoom completely, restart your laptop, and open Zoom again. The camera should now work.
My camera is covered by a physical shutter — how do I know if it's open?
Look above your screen for a small lever or slider. Slide it all the way to the side to uncover the lens. You should see a small opening. If the shutter is closed, the camera cannot see anything, even if the hardware is working. Some laptops also have a light that turns on when the camera is in use — if the light is off, the shutter may be closed.
Can I test my webcam without opening any apps?
Not really. You need to open at least the Camera app (Windows) or Photo Booth (Mac) to see whether the camera is producing an image. These are the simplest, fastest tests. If you want to test in a specific program like Zoom or Teams, open that program and look for a camera preview or settings menu.
What if I see a green light next to my camera but the image is black?
The green light means the camera is powered on and trying to work. A black image usually means the lens is covered (check for a physical shutter), the camera does not have permission in your system settings, or the driver is outdated. Start by checking for a physical shutter, then check permissions in Settings, then update the driver through Device Manager.
Do I need to restart my laptop every time I test the camera?
No, but restart if the camera worked before and suddenly stopped, or if you just installed a driver update. For routine testing, just close all other programs that might be using the camera and open the Camera app. Restart is a last resort when nothing else works.
