If your Acer laptop’s brightness controls aren’t working, it may be due to outdated drivers, disabled keyboard shortcuts, or Windows updates. Follow the troubleshooting steps to restore brightness functionality.
If you’re experiencing problems with the brightness controls on your Acer laptop’s keyboard not working, you’re not alone. This is a common issue many users face. Fortunately, there are several steps you can take to troubleshoot and resolve the issue. This article will guide you through various solutions to restore functionality to your brightness controls.
Understanding the Brightness Control Keys:
Most Acer laptops come equipped with brightness control keys, usually located on the function keys (F1 to F12). These keys often have a sun icon, indicating their function to increase or decrease the screen brightness. If these keys are not working, it could be due to software, hardware, or settings issues.
Common Reasons for Brightness Control Issues:
- Outdated Drivers: One of the most common reasons for malfunctioning brightness controls is outdated or corrupted display drivers. If your graphics driver isn’t up to date, it may not communicate effectively with your keyboard.
- Keyboard Shortcuts Disabled: Sometimes, the keyboard shortcuts for brightness control can be disabled in your laptop settings.
- Windows Updates: Recent Windows updates might lead to temporary glitches affecting your laptop’s functionality, including brightness controls.
- Function Lock: Some laptops have a function (Fn) lock feature, which might prevent function keys from working correctly.
Steps to Fix Brightness Control Issues on Acer Laptops:
1. Check Keyboard Function Key Lock
- Press the Fn Key: Hold the Fn key (usually located near the bottom-left corner of the keyboard) while pressing the brightness control key (usually F5 or F6).
- Fn Lock: If the Fn key does not work, check if you have accidentally enabled the Fn lock feature. This can usually be toggled by pressing the Esc key or the Fn key along with another key (look for a padlock icon).
2. Update Display Drivers
- Open Device Manager: Right-click the Start button and select Device Manager.
- Expand Display Adapters: Find and expand the “Display adapters” section.
- Update Driver: Right-click on your graphics driver and select “Update driver.” Choose “Search automatically for updated driver software.”

4. Use Windows Settings

- Go to System: Click on “System” and then “Display.”
