How to Brighten Up Your Windows 10 Laptop Screen
Changing the brightness on a Windows 10 laptop isn’t complicated at all. Whether you’re trying to read in a dim corner or dealing with the blinding sun outside your favourite café, adjusting brightness makes a noticeable difference. It’s great for easing eye strain, and there are a few simple ways to do it. You can use quick access settings, explore menus, or press special function keys. Let’s walk through the options without overcomplicating things.
Ways to Increase Your Screen Brightness
If you need a bit of help adjusting the brightness, here are some built-in Windows tools to get the job done:
Open the Action Centre
Press Windows + A to bring up the Action Centre icon at the bottom right of your screen. Sound familiar? It’s a quick way to access common toggles without digging through menus.
Alternatively, click the notification icon in the taskbar if keyboard shortcuts aren’t your thing.
Find and Use the Brightness Slider
Once the Action Centre pops up, look for the sun icon — that’s your brightness control. Drag the slider to the right to brighten, or to the left to dim.
Heads up: If the slider isn’t there, it might be a driver issue. Updating your display drivers can often fix this, since Windows doesn’t always get it right straight away.
Adjust Brightness via Settings
Simply slide the brightness control to your preferred level. For more precise adjustments, head to Settings: press Windows + I, then go to System > Display and tweak the slider there.
Check System Settings if Nothing Else Works
If the quick options aren’t doing the trick, try this:
- Open the Start menu.
- Navigate to Settings (Windows + I).
- Go to System > Display.
- Look for the brightness slider under Brightness and colour. If it’s missing, it might be a driver problem—time to update those.
Use the Function Keys
Many laptops have special function keys marked with sun icons, typically in the F1–F12 row. Here’s how to use them:
- Hold down the Fn key (usually at the bottom left).
- While holding Fn, press the brightness up or down key to adjust the screen.
Note: Some models might require you to enable a setting in the BIOS or UEFI for these keys to work properly.
For desktop users with external monitors, note that hardware buttons or on-screen menus are usually needed to change brightness. Check your monitor’s manual or on-screen controls for settings.
Benefits of Managing Brightness
Want your display to perform at its best? Many devices feature an automatic brightness setting — enabling it can reduce eye strain and even save battery life. Head to Settings > System > Display and toggle the auto-brightness option.
Power tips:
– Open Control Panel or head to Settings > System > Power & Sleep.
– Click on Additional power settings.
– Choose your active power plan, then click Change plan settings.
– Select Change advanced power settings.
– Expand the Display section and turn off Enable adaptive brightness if you prefer manual control.
Keeping your graphics drivers up to date is also vital to avoid issues like the brightness slider disappearing. Use Device Manager (Win + X) to check for driver updates.
Common Troubleshooting Tips
No Brightness Slider? What to Do?
If the slider is missing, chances are your display drivers need updating. Visit your device manufacturer’s website or use Windows Update (Settings > Update & Security > Windows Update) to get the latest drivers installed.
Adjusting External Monitors?
External screens usually have physical buttons or an on-screen menu for brightness control. Consult your monitor’s manual or menu for options. Some brands also offer dedicated software to make adjustments easier.
Function Keys Not Responding?
Check if the Fn lock is activated; toggling it may fix the issue. Updating keyboard or chipset drivers via Device Manager can also help. If problems persist, a restart might clear any glitches.
Why Does My Brightness Change Automatically?
This is most likely the auto-brightness feature adjusting your screen based on ambient light. To disable it:
- Open Settings (Windows + I).
- Go to System > Display.
- Turn off Change brightness automatically when lighting changes.
Does Brightness Affect Battery Life?
Yes — running the screen at higher brightness consumes more power. When on battery, dimming the display can help extend your device’s life. Adjustments can be made via Display settings or with the function keys.
Knowing how to efficiently manage your screen brightness makes a real difference to your comfort and productivity. Use the Action Centre, Settings, or function keys to find what works best in different lighting conditions. For finer control, explore third-party apps designed to fine-tune brightness even further — a handy trick for those tricky days. A little knowledge goes a long way to making your Windows 10 experience more comfortable!
