Reasons why you can’t increase the brightness of your Windows computer

There could be several reasons why you are unable to increase the brightness of your Windows computer. Here are some troubleshooting steps you can try:

Check your Power Settings:

Windows has a feature called “Adaptive Brightness,” which automatically adjusts the screen brightness based on the ambient light conditions. This feature can sometimes cause the screen brightness to dim, especially if your computer is running on battery power.

To turn off Adaptive Brightness:

1. Go to the Control Panel on your computer.
2. Click on Power Options.
3. Click on Change plan settings next to the power plan you are using.
4. Click on Change advanced power settings.
5. In the Power Options dialog box, expand the Display option.
6. Expand the Enable Adaptive Brightness option.
7. Change the On battery and Plugged in settings to Off.
8. Click OK to save the changes.

After disabling Adaptive Brightness, you should be able to manually adjust the screen brightness using the function keys on your keyboard or through the Windows settings.

Update your graphics driver:

If your graphics driver is outdated or corrupted, it can cause issues with screen brightness. You can go to your computer manufacturer’s website and download the latest graphics driver for your model.

Outdated or corrupted graphics drivers can cause issues with screen brightness on Windows computers. To update your graphics driver, follow these steps:

1. Press the Windows key + X to open the Quick Link menu.
2. Click on Device Manager from the list.
3. In the Device Manager window, expand the Display adapters option.
4. Right-click on your graphics card and select Update driver.
5. In the Update Drivers window, click on Search automatically for updated driver software.
6. Wait for Windows to search for the latest driver software and install it.
7. Once the installation is complete, restart your computer.

If Windows is unable to find an updated driver, you can visit your computer manufacturer’s website or the graphics card manufacturer’s website to download the latest driver software for your graphics card. You can then install it manually by selecting the Browse my computer for Driver software option in the Update Drivers window and selecting the downloaded driver file.

Check for malware or viruses:

Malware or viruses can cause a variety of issues on your computer, including problems with screen brightness. Use antivirus software to scan your computer and remove any threats.

To check for malware or viruses, follow these steps:

1. Install antivirus software if you don’t have one already. Windows Defender comes pre-installed on most Windows computers, but you can also choose to install third-party antivirus software.
2. Open the antivirus software and run a full system scan.
3. If any malware or viruses are found, follow the instructions provided by the antivirus software to remove them.
4. Once the scan and removal process is complete, restart your computer.

It’s a good idea to keep your antivirus software up-to-date and run regular scans to prevent malware and viruses from infecting your computer. You can also take other precautions such as avoiding suspicious websites and emails, downloading software only from trusted sources, and keeping your operating system and other software up-to-date with the latest security patches.

Check your display settings:

Sometimes the display settings on your Windows computer can prevent you from adjusting the screen brightness. To check your display settings, follow these steps:

1. Click on the Start menu and select Settings.
2. Click on System.
3. Click on Display.
4. Scroll down to the bottom of the Display settings and click on Advanced display settings.
5. Click on Display adapter properties for Display 1 (or the number of your display if you have multiple monitors).
6. In the Properties window, click on the Driver tab.
7. Click on Update Driver.
8. Choose the option to “Search automatically for updated driver software”.
9. Follow the prompts to install any available updates.

If there are no updates available for your display driver, try disabling the “Use hardware acceleration when available” option. Here’s how:

1. Right-click on your desktop and select Display settings.
2. Scroll down to the bottom of the Display settings and click on Advanced display settings.
3. Click on Display adapter properties for Display 1 (or the number of your display if you have multiple monitors).
4. In the Properties window, click on the Troubleshoot tab.
5. Click on Change settings.
6. Move the Hardware acceleration slider to None.
7. Click OK to save the changes.

Once you have made these changes, try adjusting the screen brightness again. If you’re still unable to adjust the screen brightness, you may want to try other troubleshooting steps such as updating your graphics driver or checking for malware or viruses.

Check your hardware:

If you have tried all of the above steps and are still unable to adjust the screen brightness on your Windows computer, it’s possible that there is a hardware issue. Here are some things to check:

1. Check for physical damage to the screen: If there is physical damage to your computer’s screen, such as cracks or scratches, it may be preventing you from adjusting the screen brightness. You may need to have the screen repaired or replaced to fix this issue.
2. Check the brightness control buttons: If your computer has dedicated brightness control buttons, such as the F5 and F6 keys, make sure they are working correctly. Sometimes these buttons can become stuck or damaged, preventing you from adjusting the screen brightness. Try pressing them several times to see if they respond.
3. Check the display cable: If you are using an external monitor or connecting your laptop to a separate display, check the display cable to make sure it is securely connected. A loose or damaged cable can cause issues with screen brightness.
4. Check the graphics card: If your computer has a separate graphics card, it’s possible that the card is malfunctioning or damaged. You may need to replace the graphics card or have it repaired to fix this issue.

If you are unable to identify the issue on your own, it may be best to take your computer to a professional for diagnosis and repair. They can help you determine if the issue is hardware-related and recommend the best course of action to fix it.
