Backlight Flickering or Dim Light

 

Possible Causes:

• Power supply issues.
• Loose keyboard connections.
• Wear-and-tear of backlight components.

Solutions:

1. Adjust Brightness Levels:

   • Use Fn + F4 to increase brightness. Ensure it’s not set to the lowest level.

2. Update BIOS and Drivers:

   • Visit the ASUS support website to download the latest BIOS update.
   • Ensure all drivers, especially for the keyboard and chipset, are updated.

3. Inspect Power Settings:

   • Go to Control Panel > Power Options > Change Plan Settings > Advanced Power Settings.
   • Under Keyboard Backlight, ensure it’s set to On when plugged in and on battery.

4. Check Physical Connections:

   • A loose keyboard ribbon cable may cause flickering. This requires opening the laptop to reseat the cable—contact a technician if unsure.

5. Test in a Different Environment:

   • Sometimes ambient lighting can interfere with automatic backlight adjustment. Test the keyboard in a dark room to rule this out.
