Reasons for Camera Not Working on HP EliteBook 840 G3

The HP EliteBook 840 G3 laptops are known for their excellent performance, but some users have reported difficulty with their laptop’s camera not working properly. The most common issue is that the camera gives a black screen or won’t turn on at all.

How to Fix Camera Not Working on HP EliteBook 840 G3?

If you’re experiencing problems with your HP EliteBook 840 G3 camera, don’t worry – there are several potential fixes that could resolve the issue. However, it’s important to note that you may need to try multiple solutions before finding one that works for you.

Fix #1: Webcam Driver

Firstly, it’s worth checking whether your webcam driver is corrupt or outdated. This can prevent the camera from functioning properly, so updating or reinstalling the driver should be your first course of action.

If the camera driver is corrupt or outdated, it may prevent your camera from working properly.

You can use a tool like Driver Booster to automatically search for and update outdated device drivers. You can also use HP Support Assistant or manually download them from HP site.

You can also try uninstalling the driver for your webcam by accessing the Device Manager. This can help you determine if the current driver is faulty and causing issues with your webcam.

Fix #2: Give Permission For Camera Access

Another possible reason that your HP EliteBook 840 G3 camera may not be working is that Windows may be blocking permissions for certain apps to access the camera. This can happen if you have disabled camera access for some apps in the settings.

To check if this is the case, go to Settings and click on Privacy. Then, select Camera from the left-hand menu. Here, you can enable “Allow apps to access your camera” and make sure that the app you are trying to use the camera with is enabled.

It’s important to note that this feature is designed to protect your privacy by preventing unauthorized access to your camera. However, it can also prevent legitimate apps from using the camera if they are not given permission.

Fix #3: Reset the Camera App

If you’re using the native camera app of Windows on your HP EliteBook 840 G3 laptop and none of the previous solutions have worked, resetting the app may be the answer. This can help to clear any potential glitches or bugs that may be affecting the camera’s performance.

To reset the camera app, you’ll need to go to Settings and then click on Apps. Find the camera app in the list and click on it. Next, click on Advanced settings. This will give you access to additional options for the app.

Scroll down until you find the Reset button and click on it. This will reset the camera app to its default settings, which may help to resolve any underlying problems.

It’s worth noting that resetting the camera app may delete any custom settings you have configured. However, this is a small price to pay if it means getting your camera back up and running.

Third Party Apps

In addition to the solutions mentioned above, if you’re using a third party app with your HP EliteBook 840 G3 camera, it’s possible that the app itself may be causing the issue. In this case, reinstalling the app may be the best course of action.

Third party apps can sometimes conflict with updates or changes to your device’s system, causing compatibility issues for your camera. Reinstalling the app ensures that it is properly integrated with your device’s software, potentially resolving any conflicts.

Fix #4: Check Your Antivirus

It’s also possible that your antivirus program may be blocking access to the camera. Some antivirus programs have built-in settings that allow you to control which apps can use the camera, so it’s worth checking if yours has this feature enabled.

If it does, make sure that the app you want to use with the camera is listed as an allowed app. If it isn’t, add it to the list and try connecting your camera again.

If you don’t find any settings related to the camera in your antivirus program, consider disabling or uninstalling the program temporarily. This should allow you to check if the issue lies with the antivirus itself.

Fix #5: Corrupt Registry

Another potential cause of camera issues on the EliteBook 840 G3 is corrupt Windows Registry settings. This can occur if you’ve recently installed or uninstalled software that has interfered with these settings.

To fix this problem, you can try restoring your computer to a previous system restore point, or manually editing the Registry to remove any conflicting entries. Here’s how you can do it step by step:

Step #1: Create a System Restore Point

Before you make any changes to the Registry, it’s crucial to create a backup or restore point. This will ensure that you can revert any changes in case something goes wrong.

To create a restore point, follow these steps:

  1. Type “Create a restore point” in the Windows search box and click on the result.
  2. Click on the “Create” button.
  3. Name your restore point and click “Create” again.
  4. Wait for the process to complete.

Step 2: Access the Registry Editor

The first step in fixing the corrupt Registry is to access the Registry Editor. Here’s how:

  1. Type “regedit” in the Windows search box and click on the result.
  2. Click “Yes” if prompted to allow the app to make changes.
  3. The Registry Editor will open.

Step 4: Navigate to the Camera Settings

Once you’re in the Registry Editor, navigate to the camera settings. Here’s how:

  1. Go to “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Media Foundation\Platform”.
  2. Right-click on the “Platform” folder and then New > DWORD 32-bit Value.
  3. Name the new value “EnableFrameServerMode”.
  4. Right-click on the new value and change its value data to “0“.
  5. Press “OK” and then close the Registry Editor.

Step 6: Restart Your Computer

Once you’ve made these changes, you’ll need to restart your computer to apply them. After the reboot, check if your camera issue has been resolved.

In conclusion, fixing a corrupt Windows Registry can be a daunting task. However, by following these step-by-step instructions carefully, you should be able to fix the camera issue on your HP EliteBook 840 G3 laptop.

Fix #6: Webcam Hardware Defect

Finally, it’s possible that the camera itself is defective. If none of the above solutions have worked, you may need to contact HP Support for assistance or a professional. They can help determine if there is a hardware issue with your laptop and provide advice on how to fix it.

Conclusion

It’s important to remember that troubleshooting camera issues can be a time-consuming process, especially if you need to try multiple potential fixes. However, with patience and persistence, you should be able to get your EliteBook 840 G3 camera working properly again in no time.

I’ve provided six potential fixes that may help resolve any underlying problems causing your camera not to work properly. Whether it’s resetting the app or disabling your antivirus program, these tips should give you an idea of where to start looking for answers.
