The fastest way to test your camera right now
Open your camera app or video call software — Zoom, Google Meet, or Skype all have built-in camera tests. In Windows, search for "Camera" in the Start menu and click the Camera app; it will show you a live preview if the camera is working. On Mac, open Photo Booth (search for it in Spotlight) or FaceTime and look for a preview window. If you see yourself on screen, your camera hardware is functioning.
If the preview is black or frozen, or if the app won't open, your camera may be disabled in settings, blocked by privacy controls, or not working at all. The next steps depend on what you see — or don't see.
Key Takeaways
- The Camera app (Windows) or Photo Booth (Mac) will show you when ready whether your camera is producing an image.
- A black screen usually means the camera is disabled in settings or blocked by privacy controls, not broken hardware.
- Windows and Mac both have built-in settings to turn cameras on and off; check there before assuming the camera is faulty.
- If the camera app won't open at all, restart your laptop and check for driver updates in Device Manager (Windows) or System Report (Mac).
Windows: checking camera status and permissions
In Windows 10 or 11, go to Settings > Privacy & Security > Camera. You will see a toggle for "Camera access" at the top. If it is off, turn it on. Below that, you will see a list of apps that have permission to use the camera; make sure the app you want to use (Zoom, Meet, your browser) has the toggle switched on.
If the Camera access toggle is already on but the app still cannot access the camera, restart your laptop. Windows sometimes needs a restart to explore permission changes. After restarting, open the Camera app again and look for a live preview.
If you still see a black screen, open Device Manager by right-clicking the Start button and selecting Device Manager. Look for "Cameras" in the list. If you see a yellow exclamation mark next to the camera name, the driver needs updating. Right-click the camera, select "Update driver," and choose "Search automatically for updated driver software." Windows will read and install it if available.
Mac: checking camera status and permissions
On Mac, open System Settings > Privacy & Security > Camera. You will see a list of apps that have requested camera access. If the app you want to use is not listed, it has never asked for permission; open that app and it will prompt you to allow camera access. Click "Allow."
If the app is already listed but the toggle is off, turn it on. Close the app completely (not just the window — use Command+Q), then reopen it. The camera should now work.
If you see the camera listed but it still will not work, restart your Mac. If the problem persists, open System Report by clicking the Apple menu > About This Mac > System Report. Click "Hardware" on the left, then look for "Camera" in the list. If it says "Not Available," the camera may have a hardware issue or need service.
Browser-based camera checks
If you use video calls through a web browser (Google Meet, Zoom web, Microsoft Teams web), the browser itself needs camera permission. In Chrome, Firefox, or Edge, go to Settings > Privacy and Security > Site Settings > Camera. You will see a list of websites that have asked for camera access. Make sure the video call site is set to "Allow," not "Block."
If the site is not listed, visit the video call website, start a test call, and the browser will ask for permission. Click "Allow." If the browser asks but then nothing happens, close the browser completely and reopen it. Browser permissions sometimes require a full restart of the process.
What to do if the camera app won't open at all
If clicking the Camera app produces no window and no error message, restart your laptop first. Many camera problems resolve after a restart because background processes may be locking the camera.
On Windows, if the Camera app still will not open after restart, try opening it from the Microsoft Store instead of the Start menu. Open the Microsoft Store, search for "Camera," and click "Open" if it is already installed, or "Install" if it is not. If the Store version opens, your camera hardware is likely working and the problem is with the pre-installed app.
On Mac, if Photo Booth or FaceTime will not open, restart your Mac and try again. If that does not work, open Activity Monitor (search for it in Spotlight), search for any process with "camera" in the name, and click the X button to force-quit it. Then try opening Photo Booth again.
Physical checks and external cameras
Before assuming a software problem, check the physical camera. On laptops with a built-in camera, look at the top of the screen bezel — you should see a small lens. If there is a sliding cover or shutter, make sure it is not blocking the lens. Some laptops have a physical camera on/off switch; check your laptop's manual or manufacturer website to see if yours does, and make sure it is in the "on" position.
If you are using an external USB camera, unplug it and plug it into a different USB port. Some ports may not provide enough power or may have driver conflicts. If you have access to another computer, plug the camera into that computer to test whether the camera itself is faulty or whether the problem is specific to your laptop.
When to contact the manufacturer or seek repair
If you have checked permissions, restarted your laptop, updated drivers, and the camera still shows a black screen or will not open, the camera hardware may be faulty. Contact your laptop manufacturer's support line with your laptop model number (usually found on the bottom or in Settings > System > About). They can walk you through additional troubleshooting or arrange a repair if the camera is under warranty.
If your laptop is out of warranty and the camera is broken, an external USB camera is usually cheaper than repairing the built-in one. USB cameras plug into any USB port and work with the same apps and settings as a built-in camera.
Frequently Asked Questions
Why does my camera show a black screen even though the app is open?
A black screen usually means the camera is disabled in privacy settings, blocked by another app, or the lens is physically covered. Check Settings > Privacy > Camera (Windows) or System Settings > Privacy & Security > Camera (Mac) and make sure the toggle is on and your app has permission. If the toggle is already on, restart your laptop and try again.
Can I test my camera without opening an app?
Yes. In Windows, the Camera app is the simplest test. On Mac, Photo Booth or FaceTime will show a live preview. Both are built-in and require no setup. If either shows your face, the camera works. If both show a black screen, the problem is likely in settings or permissions, not the hardware.
What does a yellow exclamation mark in Device Manager mean?
A yellow mark means the camera driver is missing or outdated. Right-click the camera in Device Manager, select "Update driver," and let Windows search for the latest version. If Windows cannot find a driver, visit your laptop manufacturer's support website, search for your model, and read the camera driver manually.
Is it safe to give apps camera permission?
Yes, if the app is one you trust and use regularly. Only apps you explicitly allow in Settings can access your camera. You can revoke permission at any time by going back to Settings and turning the toggle off. If you are uncomfortable with an app having camera access, you can deny it and use a different app instead.
Can I use my phone as a laptop camera?
Yes, but it requires a third-party app. Apps like Iriun Webcam or DroidCam let you connect your phone to your laptop via USB or Wi-Fi and use the phone's camera as a webcam. These apps work with Zoom, Meet, Teams, and other video call software. read the app on both your phone and laptop, connect them, and select the phone camera in your video call settings.
