If you’re facing issues with your Chromebook’s brightness not adjusting, you’re not alone. Many users encounter this problem, and it can be frustrating when you’re trying to optimize your display for different lighting conditions.
Thankfully, there are several ways to troubleshoot and resolve the issue. In this guide, we’ll walk you through some effective solutions to get your Chromebook’s brightness working again.
How to Fix Brightness Not Working on Chromebook
This issue can arise for various reasons, including software conflicts, Night Mode, and Battery Saver being enabled, among others. While these features are intended to enhance your Chromebook’s performance and battery efficiency, they can sometimes interfere with the brightness control.
This results in brightness control not working properly on your Chromebook. To fix this, follow the guide below.
1. Restart Your Chromebook
Sometimes, a simple restart can resolve minor glitches and bugs that affect your Chromebook’s functionality. Here’s how to restart your Chromebook:
1. Click on the clock, Wi-Fi, or battery icon in the bottom-right corner.
2. Click on the power icon.
3. Select Restart.
After restarting, try adjusting the screen brightness again. Hopefully, this resolves the issue.
2. Adjust Brightness Using Quick Settings
Once your Chromebook has restarted, you can adjust the brightness through Quick Settings. Quick Settings allows you to easily access and modify important features of your Chromebook without navigating through the main settings menu.
To adjust the brightness:
1. Click on the clock, Wi-Fi, or battery icon in the bottom-right corner of your screen.
2. Look for the brightness slider and move it left or right to adjust the screen brightness.
3. Use Keyboard Shortcuts to Adjust Brightness
If you prefer using the keyboard, Chromebooks come with dedicated function keys to control brightness. Press the sun icon key to adjust the screen brightness. The smaller sun icon reduces the brightness, while the larger sun icon increases it on your Chromebook.
These shortcuts provide a quick and easy way to change your screen’s brightness without needing to use the trackpad or mouse.
4. Disable Night Light
Night Light (or Night Mode) is designed to reduce blue light exposure and make your screen warmer at night. However, it can sometimes cause the brightness to seem dimmer than usual. If you’re having trouble adjusting the brightness, try turning off Night Mode:
1. Click on the clock, Wi-Fi, or battery icon in the bottom-right corner.
2. Next to the brightness slider, click on the arrow icon.
3. Turn off the toggle to disable Night Mode. This should help restore the normal brightness of your screen.
5. Disable Battery Saver
Battery Saver mode reduces the brightness of your screen to save power when your Chromebook’s battery is running low. To ensure this isn’t causing the issue, turn off Battery Saver. Once done, you should be able to adjust your brightness to your liking.
To disable the battery saver on you Chromebook, follow these steps:
1. Click on the App Launcher icon and open Settings.
2. Under System Preferences, click on Power.
3. Turn off the Battery Saver option.
6. Update ChromeOS
If you’re still unable to adjust the brightness after following the previous steps, it could be because you’re using an outdated version of ChromeOS. To check for updates and ensure you’re running the latest version of ChromeOS:
1. Click on the App Launcher icon and open Settings.
2. In the Settings, click on About ChromeOS.
3. Click on Check for Updates.
Updating your Chromebook to the latest version can resolve software issues that might be preventing brightness adjustments.
Conclusion
That’s it! These are the most effective methods to fix the brightness not working issue on your Chromebook. By following this guide, you should be able to regain full control over your screen brightness. If you’re still facing issues after trying all of these solutions, you can try performing a Powerwash to reset your Chromebook to its default factory settings.
