If you’re on a laptop running Windows 10, your laptop manufacturer might have set up shortcuts on the keyboard to turn the brightness up and down.

Find the toggle to lower the screen brightness on the keyboard, and press it to activate the command. Do note that some OEMs require a user to press the brightness toggle with the Fn key.

Alternatively, you could also turn the brightness up with a toggle for the same on the keyboard.

2] Using Settings

Adjust Brightness Settings

The Settings panel could help you decrease the brightness of the computer manually. Here’s how to do so:

  • Open the Settings Panel in Windows 10 (Win + I)
  • Navigate to System -> Display
  • Under Brightness and Color, drag the slider to the left to decrease the brightness, and alternatively to the right to increase it.
  • You could see the effect in real-time.

3] Via Mobility Center

Adjust Brightness Mobility Center

The mobility center, accessed by pressing the Win + X key on the keyboard, could decrease your computer’s brightness. Here’s how:

  • Press the Win + X key on the keyboard and choose Mobility Center from the drop-up menu.
  • Under Display Brightness, drag the slider to the left to decrease the brightness, where the extreme left implies the lowest brightness level, and the extreme right implies the highest possible one.

4] via Shortcut

Adjust Brightness Shortcut

The Notification Panel in Windows 10 houses a handy shortcut to either decrease or increase your primary monitor’s brightness. Click on the message icon present at the bottom right corner of the screen and drag the slider within to adjust the brightness.

5] Automatically Adjust Brightness for Battery Life

Adjust Brightness Low Battery

If you’re running low on battery power, reducing your Windows computer’s brightness levels could help you squeeze out longer battery life. Windows can help you automatically do so when the battery’s running low. Here’s how to set it up:

  • Open the Settings Panel in Windows 10 (Win + I)
  • Navigate to System -> Battery
  • Here, turn on Battery Saver and check the checkbox stating Lower screen brightness while in battery saver.
  • With this, whenever your battery is running low on power, Windows will trigger the Battery Saver, which will tone down the brightness levels.

6] Adaptive Brightness

If your display output device has a built-in ambient light sensor that could detect the amount of light around you, ideally, then Windows can automatically adjust the brightness levels for your computer based on the stats.

  • Open the Settings Panel in Windows 10 (Win + I)
  • Navigate to System -> Battery
  • Here, if you notice an option stating Change brightness automatically when lighting changes, turn in On.
  • However, if you cannot find a similar option, your display output device might lack the sensor.
