Start with the simplest fixes first
A webcam that won't work usually fails for one of three reasons: the camera is physically blocked, the software driver needs updating, or the app doesn't have permission to use it. Before you assume the hardware is broken, check these things in order, because most webcam problems solve themselves in the first five minutes.
Begin by looking at the camera lens itself. If it has a physical shutter or cover, open it. Dust, a sticker, or even a piece of tape over the lens will make the camera appear completely dead. Wipe the lens gently with a soft, dry cloth—the kind you use for eyeglasses works well. Then restart the app you're trying to use and test it again.
Next, check whether your laptop's keyboard has a camera toggle. Some models have a dedicated key with a camera icon, or you can hold the Fn key and press a function key (F2, F3, or F5 depending on the brand) to turn the camera on and off. If the camera is toggled off, press the key again to turn it back on.
Key Takeaways
- Check the physical lens first—remove any cover, shutter, or obstruction, and wipe it clean with a soft cloth.
- Look for a camera toggle key on your keyboard (often Fn + a function key) and make sure the camera is turned on.
- Update your camera driver through Device Manager on Windows or System Report on Mac, because outdated drivers cause most software failures.
- Grant camera permission to the app in your operating system settings, since many programs cannot access the camera without explicit approval.
- Restart your laptop after making any changes, because the operating system needs to reload drivers and permissions.
Update the camera driver on Windows
An outdated or missing driver is the most common reason a webcam stops working in software. The driver is the translator between your operating system and the camera hardware. When it's out of date, Windows can't talk to the camera properly.
Open Device Manager by right-clicking the Start button and selecting "Device Manager" from the menu. Look for a section called "Cameras" or "Imaging devices." Click the arrow next to it to expand the list. You should see your camera listed there—it might say "Integrated Camera," "Webcam," or the manufacturer's name like "Logitech" or "Intel."
Right-click on the camera name and select "Update driver." Choose "Search automatically for updated driver software." Windows will search online for the newest version. If it finds one, it will install it automatically. If Windows says the driver is already up to date but your camera still doesn't work, right-click the camera again, select "Uninstall device," and restart your laptop. Windows will reinstall the driver from scratch when it boots up.
If you don't see a Cameras section in Device Manager at all, expand "Other devices" and look for an unknown device or something with a yellow warning icon. Right-click it and select "Update driver"—this might be your camera with a missing driver.
Update the camera driver on Mac
Mac laptops rarely have driver problems because the operating system handles camera software automatically, but you should still check for system updates. Click the Apple menu in the top-left corner and select "System Settings" (or "System Preferences" on older Macs). Click "General," then "Software Update." If updates are available, install them and restart your Mac.
If you want to see what camera your Mac recognizes, click the Apple menu, select "About This Mac," and click "System Report." In the left sidebar, click "Hardware," then scroll down to find "Camera" in the list. If your camera appears there, the hardware is working and the problem is likely a permissions issue or an app problem, not a driver problem.
Grant camera permission to your app
Modern operating systems require you to give each app permission to use the camera. If you installed a new app or updated your operating system, the app might have lost permission and can no longer access the camera.
On Windows: Open Settings by pressing the Windows key and typing "Settings." Click "Privacy & security" in the left sidebar, then click "Camera." Make sure "Camera access" is turned on at the top. Then scroll down to "Allow apps to access your camera" and turn on the toggle next to the app you want to use. If the app isn't listed, it means it hasn't requested permission yet—open the app, try to use the camera, and Windows will prompt you to allow it.
On Mac: Click the Apple menu, select "System Settings," and click "Privacy & Security" in the sidebar. Click "Camera" on the left. You'll see a list of apps that have requested camera access. Make sure the toggle next to your app is turned on. If your app isn't listed, open it and try to use the camera—Mac will ask you to allow it.
Restart your laptop and test in a different app
After you've updated the driver or changed permissions, restart your laptop completely. Don't just put it to sleep—shut it down and turn it back on. This forces the operating system to reload all drivers and settings.
Once it's back on, test the camera in a different app to figure out whether the problem is with the camera itself or with one specific program. Open the Camera app (built into Windows and Mac) or try a video call in a different program. If the camera works in one app but not another, the problem is with that specific app's settings or installation, not with your hardware or drivers.
If the camera still doesn't work in any app, disconnect any external USB devices (external hard drives, printers, hubs) and restart again. Sometimes a USB device can interfere with the camera's connection.
Check for hardware conflicts and BIOS settings
On Windows laptops, a hardware conflict can disable the camera without any obvious warning. Go back to Device Manager and look for any devices with a yellow exclamation mark or red X. If you see one, right-click it and select "Uninstall device." Restart your laptop and Windows will try to reinstall it.
Some laptops have camera settings in the BIOS (the firmware that runs before Windows starts). This is rare, but if you've tried everything above and the camera still doesn't appear in Device Manager at all, you may need to restart into BIOS and look for a camera or integrated peripherals setting. The key to enter BIOS varies by manufacturer—it's usually Delete, F2, F10, or F12, pressed repeatedly as the laptop starts up. Look for a setting like "Integrated Camera" or "Onboard Camera" and make sure it's enabled. If you're not comfortable in BIOS, skip this step.
When to replace the camera
If you've updated the driver, granted permissions, restarted the laptop, and tested in multiple apps, and the camera still doesn't work, the hardware itself may be faulty. Laptop cameras are soldered to the motherboard and cannot be replaced by most users—you'll need to contact the manufacturer or a repair shop.
Before you do that, try one last thing: borrow a USB webcam from someone and plug it in. If the external camera works, your built-in camera is definitely broken. If the external camera also doesn't work, the problem is with your operating system or a deeper hardware issue, and you should contact support for your laptop brand.
Frequently Asked Questions
Why does my camera work in one app but not another?
The app that doesn't work either doesn't have camera permission in your operating system settings, or it has a bug or outdated code. Check the app's permission in Settings (Windows) or System Settings (Mac) and turn the camera toggle on. If it's already on, try uninstalling and reinstalling the app.
My camera shows up in Device Manager but still won't work. What now?
Right-click the camera in Device Manager, select "Uninstall device," and restart your laptop. This forces Windows to reinstall the driver completely. If that doesn't work, right-click the camera again and select "Properties" to see if there's an error code that tells you what's wrong.
Can I use an external USB webcam if my built-in camera is broken?
Yes. Plug a USB webcam into any open port and Windows or Mac will recognize it automatically. You may need to grant it permission in your privacy settings, but most external cameras work without installing any software.
How do I know if my camera is disabled by a keyboard shortcut?
Try pressing Fn and each function key (F1 through F12) one at a time while looking for a camera icon on the key. When you find it, press that combination. If the camera still doesn't work after that, the problem isn't a keyboard toggle.
Is it safe to update my camera driver from Windows Update?
Yes. Windows Update only installs drivers from Microsoft's verified list. It's the safest way to update. Never read drivers from random websites—always use Device Manager or the manufacturer's official website.
