How to turn on and use a laptop's built-in camera

The short answer

A laptop’s built-in camera is usually already installed. You turn it on by opening the camera app (or a video-call app) and allowing camera permission when the system asks. On most Windows machines, including HP, Dell, MSI and Samsung, that app is named Camera. On a Mac it is Photo Booth for stills and FaceTime for video. On a Chromebook it is Camera. The webcam itself sits in the top bezel of the display; a tiny LED next to it lights when the sensor is in use.

“Turn on the camera” can mean three different things: physically uncovering the lens, giving an app permission to use the webcam, or starting a live preview. Covering the lens with a slider or sticker blocks the image even when the app is running. Permission is granted per app, so allowing Camera does not automatically allow a browser or meeting tool. A live preview proves the sensor can capture video in that app; it does not prove the same feed will appear in a call, and it says nothing about microphone quality or how the picture will look to other people.

Before you start

Sit in front of the screen with the lid fully open. Slide any privacy shutter off the lens until the opening is clear. If a sticker covers the camera, peel it away. Confirm the laptop is awake and signed in. You do not need extra hardware for the built-in webcam. A working preview in the camera app is the first success check; meeting apps and browsers each need their own permission and a separate check.

Find the camera on the laptop

Look along the top edge of the screen, usually in the centre. You should see a small lens, often with a status light beside it. Some HP and other Windows models put a sliding cover over that lens; slide it until the hole is fully open. Convertibles and 2-in-1s use the same bezel camera whether the device is in laptop or tent mode. There is no separate “webcam” port to plug in. If you cannot see a lens at all, the model may ship without a camera, or the bezel may hide it behind a closed shutter.

Windows laptops, including HP, Dell, MSI and Samsung

These brands all use Windows in the same way for the built-in webcam. The steps below apply to a typical HP laptop and to Dell, MSI and Samsung Windows machines.

• Press the Windows key and type Camera, then open the Camera app from the results.
• If Windows asks whether Camera can access the camera, choose Allow.
• Wait for a live picture of yourself. The status light next to the lens should turn on.
• To take a still photo, tap or click the shutter (camera) button. To record video, switch to video mode if the app shows that option, then start and stop recording.
• Open the saved file from the notification, or look in the Pictures folder, usually under Camera Roll.

A live, correctly oriented image with the LED on means this app can reach the sensor and capture video. It does not confirm that Zoom, Teams, Meet or a browser tab can do the same, and it does not test the microphone.

Allow camera access in Windows settings

If the Camera app shows a black screen, a permission message, or “We can’t find your camera”, check privacy settings before assuming the hardware has failed.

• Open Settings, then Privacy & security (Windows 11) or Privacy (Windows 10).
• Select Camera.
• Turn on Camera access so Windows may use the webcam at all.
• Turn on Let apps access your camera.
• Confirm Camera is listed and allowed. If you will join a call in a browser, also allow desktop apps and the browser you use.

After changing these switches, close and reopen the Camera app. A preview that now appears means permission was the blocker. If the list of apps never includes Camera, search again for the app or install it from the Microsoft Store. This article does not include measured failure rates or a list of which HP, Dell, MSI or Samsung models omit a webcam.

HP-specific camera settings you may see

On some HP laptops the function-key row includes a camera key, often on F4 or F8, used with the Fn key. Pressing that key can disable the webcam at a firmware level. If the Camera app still cannot find a device after Windows permissions are on, hold Fn and tap the camera key once, then reopen Camera. The key’s icon is a small lens; an overlay or LED change, when the model shows one, is the cue that the camera was toggled.

HP Support Assistant and similar vendor utilities may list the webcam under devices, but they are optional. Windows Device Manager also lists imaging devices; a webcam shown there without a warning icon means the system has detected the hardware. Detection is not the same as a working preview. This guide does not treat any HP utility as required, and it does not claim a specific HP settings panel exists on every model.

Chromebook

• On the shelf or in the launcher, open Camera.
• Grant camera permission if ChromeOS asks.
• Check that the preview shows you, not a frozen or black frame.
• Tap the shutter to take a photo, or switch to video and record.
• Find the file in Files, usually under Camera.

ChromeOS also asks again when a website wants the camera. Allowing the Camera app does not allow that site. A site permission prompt is a separate step, and a successful local photo still leaves website capture untested.

Mac and MacBook

macOS does not ship a single app named Camera. Photo Booth is the built-in stills and short-clip viewer; FaceTime is the built-in video-call app. Continuity Camera can also use an iPhone as a camera, which is a different device from the MacBook’s webcam in the notch or bezel.

• Open Photo Booth from Launchpad or Spotlight.
• If macOS asks for camera access, allow it.
• Confirm a live preview. Take a photo with the red shutter button.
• For a video call, open FaceTime instead and start a call or open Video so you can see your own feed.
• To review which apps may use the camera, go to System Settings, Privacy & Security, Camera, and enable the apps you need.

A Photo Booth snapshot proves the Mac can capture a still from the built-in camera in that app. FaceTime’s self-view proves a live video session in FaceTime. Neither proves a third-party meeting app or a browser has permission, and neither tests the microphone.

Use the camera in a video call

Open the meeting app or browser tab and look for a camera or video button. Choose the built-in camera from the device list if more than one camera appears. Allow camera permission when the app or browser prompts. You should see your own live tile before you join, or immediately after, depending on the tool.

That self-view means this app received a video stream. It does not measure frame rate, lighting, or how sharp you look to others, and it does not confirm they can hear you. Microphone permission is separate: the app can show video while audio is muted, blocked, or picking up the wrong input. Virtual backgrounds and blur are call effects applied to the video feed; they are not the same as the real room behind you, and they are not the same as editing a still photo after you take it.

Take a picture with the laptop camera

In the Camera app (Windows or Chromebook) or Photo Booth (Mac), face the lens, check the preview, and press the shutter. Hold still until the capture finishes. Open the photo from the app’s thumbnail or from Pictures / Camera Roll (Windows), Files / Camera (Chromebook), or Photos (Mac). If the image is black, the shutter or a cover is still over the lens. If it is very dark, add light in front of you; the built-in camera has a small sensor and no flash on most laptops.

A saved photo shows that still capture worked in that app. Cropping, replacing, or blurring the backdrop later is photo editing. That is separate from a virtual background used only inside a call.

If the camera stays off or the picture is black

• Open the privacy shutter fully and remove any cover.
• Close other apps that might already be using the webcam, then reopen Camera, Photo Booth or your meeting app. Only one app can typically own the sensor at a time.
• Recheck camera permission for that specific app, including the browser if you join from a tab.
• On Windows, confirm the camera is not disabled with an Fn camera key, then open Device Manager, Imaging devices, and check that the webcam is enabled.
• Restart the laptop once after permission changes.
• If Device Manager shows no imaging device, or the Camera app never finds hardware, the machine may lack a webcam or the module may need service. This guide cannot confirm that from here.

A black preview with the LED off often means the app never started the sensor (permission, disabled device, or no camera). A black preview with the LED on often means the lens is covered. A frozen last frame can mean another app still holds the camera. None of these checks measure call quality for remote viewers.

What a successful test actually shows

Use this as a readiness check, not as a full dress rehearsal of a meeting.

• Camera app or Photo Booth preview: the built-in sensor works in the system camera app, the lens is uncovered, and that app has permission. Untested: other apps, browsers, microphone, lighting for other people, and network.
• Meeting-app self-view: that app received a live video stream and has camera permission. Untested: how you look to others, bitrate, and audio.
• Browser prompt allowed: that site in that browser may use the camera until you revoke it. Untested: other sites and other browsers.
• Saved still photo: still capture and file saving worked. Untested: video, audio, and call effects.

No input-level target (such as a brightness number, resolution, or microphone loudness) is supplied for this setup, so this guide does not recommend a numeric threshold. Judge the preview by eye: you should recognise your face, the image should update as you move, and the status light should match when the camera is on. If you also need sound, test the microphone in the same app with a separate check; camera success does not imply intelligible audio.
