This guide will show you how to use your keyboard to adjust your screen brightness, making it easier on your eyes and conserving battery life.
Step 1: Identify the Brightness Keys
Look at your keyboard and find the keys with brightness icons, usually on the top row.

You might need to press it several times to reach the perfect brightness. It’s a bit like turning down the volume on your TV until it’s just right.
Step 4: Confirm the Change
Check your screen to ensure the brightness is at a comfortable level.
If it’s too dim, you can easily adjust it back up by following the same process with the increase brightness key.
Step 5: Test Different Levels
Experiment with different brightness levels to find the one that best suits your environment.
Depending on whether you’re in a dark room or a bright office, you’ll want different settings. This flexibility helps save battery life and reduce eye strain.
Once you’ve adjusted the brightness, your screen will reflect the new settings immediately. You can enjoy a more comfortable viewing experience without navigating through complex settings or menus.
