You probably need to change your screen brightness regularly. When it’s bright outside, you want to turn it up so you can see. When you’re in a dark room, you’ll want it dim so it doesn’t hurt your eyes. Decreasing your screen brightness will also help save you power and increase your laptop’s battery life.
Aside from manually changing the screen brightness, you can have Windows change it automatically in a variety of ways. Windows can change it based on whether you’re plugged in, based on how much battery power you have left, or using an ambient light sensor built into many modern devices.
How to Adjust Brightness Manually on a Laptop or Tablet
On most laptop keyboards, you’ll find shortcut keys that allow you to quickly increase and decrease your brightness. Often, these keys are part of the row of F-keys–that’s F1 through F12–that appear above the number row on your keyboard. To adjust the screen brightness, look for an icon that corresponds to brightness–often a sun logo or something similar–and press the keys.
These are often function keys, which means you may have to press and hold the Fn key on your keyboard, often located near the bottom-left corner of your keyboard, while you press them.
You can also adjust the display brightness from within Windows as well. This is especially helpful if your keyboard doesn’t have these keys, or if you’re using a tablet and you have to do it within software.
On Windows 10, you can click the battery icon in the notification area and click the brightness tile that appears. This adjusts the brightness in increments of 25% each time you tap it. You can also swipe in from the right or open the Action Center from your system tray and use the quick settings tile there.
You’ll find this option in the Settings app on Windows 10, too. Open the Settings app from your Start menu or Start screen, select “System,” and select “Display.” Click or tap and drag the “Adjust brightness level” slider to change the brightness level.
If you’re using Windows 7 or 8, and don’t have a Settings app, this option available in the Control Panel. Open the Control Panel, select “Hardware and Sound,” and select “Power Options.” You’ll see a “Screen brightness” slider at the bottom of the Power Plans window.

You’ll also see this option in the Windows Mobility Center. Launch it by right-clicking the Start button on Windows 10 and 8.1 and selecting “Mobility Center,” or pressing the Windows key + X on Windows 7. Change the “Display brightness” slider in the window that appears.
How to Adjust Brightness Manually on an External Display
Most of the methods in this article are designed for laptops, tablets, and all-in-one PCs. However, if you’re using a desktop PC with an external display–or even connecting an external display to a laptop or tablet–you’ll need to adjust his setting on the external display itself, and you usually won’t be able to do it automatically.

Look for “brightness” buttons on the display and use them to adjust the display brightness. You may instead need to press some sort of “Menu” or “Options” button before you can access an on-screen display that will allow you to increase or decrease the brightness. You’ll often find these buttons near the power button on a computer monitor. With some monitors, you may also be able to adjust your screen’s brightness with an app like ScreenBright or Display Tuner, though they won’t work with all monitors.
How to Automatically Adjust Brightness When You’re Plugged In
RELATED:Should You Use the Balanced, Power Saver, or High Performance Power Plan on Windows?
You can set different display brightness levels on your laptop or tablet based on whether or not you’re plugged into an outlet or not. For example, you could have it set to a high brightness level when you’re plugged in, and a lower one when you’re on battery power. Windows would then automatically adjust your brightness.
To adjust this, open the Control Panel. Select “Hardware and Sound,” select “Power Options,” and click the “Change plan settings” link next to the power plan you’re using. You’re probably using the Balanced power plan.
Configure different screen brightness levels for “On battery” and “Plugged in” under “Adjust plan brightness.” This setting is tied to your power plan. You can configure different screen brightness levels for different power plans and switch between them, if you like (though we don’t think power plans are really necessary).
How to Automatically Adjust Brightness Based on Remaining Battery Life

You can automatically adjust your display’s backlight based on how much battery power your laptop or tablet has left, too. On Windows 10, you can use the Battery Saver feature to do this. Open the Settings app, select “System,” and select “Battery saver.” Click or tap the “Battery saver settings” link.
Ensure the “Lower screen brightness while in battery saver” option is enabled, then choose the percentage at which you’d like Battery Saver to kick in. When Battery Saver activates at that level, it will decrease your backlight and saving you power. By default, Battery Saver kicks in when you have 20% battery remaining.
Unfortunately, there’s no way to adjust the exact brightness level Battery Saver will choose. You can also manually enable this feature from the battery icon.
How to Automatically Adjust Brightness Based on Ambient Light

Many modern laptops and tablets have an ambient brightness sensor, which works similarly to the one found on smartphones and tablets. Windows can use the sensor for “adaptive brightness,” automatically increasing your display brightness when you’re in a bright area, and decreasing the brightness when you’re in a dark room.
This is convenient, but some people find that it gets in the way, too. It may automatically decrease or increase your display brightness when you don’t want it to, and you may prefer managing brightness manually with the settings above. You may want to try it on and off to decide which you like better.
To enable or disable this feature on Windows 10, open the Settings app, select “System,” and select “Display.” Turn the “Change brightness automatically when lighting changes” option on or off. You’ll only see this option if your device has an ambient brightness sensor.
You can change this setting through the Control Panel, too. Open the Control Panel, select “Hardware and sound,” select “Power Options,” click “Change plan settings” next to the power plan you’re using, and click “Change advanced power settings.”
Expand the “Display” section here, and then expand the “Enable adaptive brightness” section. The options here let you control whether adaptive brightness is used when you’re on battery or when you’re plugged in. For example, you could disable it when you’re plugged in and leave it enabled when you’re on battery power.
You can adjust your screen brightness both automatically and manually, and both have their time and place. Enabling automatic brightness won’t prevent you from tweaking your brightness with hotkeys or the options in Windows whenever you feel like it, either, so you have nothing to lose by trying all the above options out.

Most of the mid to high-end laptops today offer backlit keyboards. Backlit keyboards make typing easier at low light conditions, especially for those who cannot do touch typing.
Backlit keyboards or illuminated keyboards can be turned on or off using keyboard shortcuts on all laptops. For instance, I can use Fn + Spacebar key to turn on the keyboard backlight on my ThinkPad T series laptop.
Many laptop users often ask if there is a dedicated setting to adjust the backlit keyboard brightness in Windows 10. The answer is both yes and no.
Adjusting backlit keyboard brightness in Windows 10
While, sadly, there is no built-in setting in Windows 10 to adjust or change backlit keyboard settings, some OEMs do offer their own software to change default settings of backlit keyboard brightness. For instance, Dell Windows 10 laptops offer settings to turn on or off the backlit keyboard, adjust the keyboard brightness, automatically turn off the backlight after 5/10/30/60/300 seconds of inactivity.
Dell users can open Keyboard properties dialog and then switch to Backlight tab to see all keyboard brightness settings.
Sony also offers options to adjust default settings of keyboard brightness on some of its models. You can open VAIO Control Center and then click Keyboard and Mouse and Backlit Keyboard to see settings. Here, you can configure the software to automatically turn on or off the backlit keyboard to automatically turn on or off based on ambient light. Like Dell, Sony also offers an option to automatically turn off the keyboard backlight after inactivity of keyboard operations for X amount of time.
Lenovo doesn’t offer much to change the default settings of backlit keyboard. However, you can set the keyboard brightness to medium or high brightness using Fn + Space hotkey. That is, if you press Fn + Space once, the driver turns on the backlit keyboard with medium brightness. Pressing Fn + Spacebar again changes the brightness to high. Pressing the hotkey again will turn off the backlit keyboard.
All recent MacBook models automatically adjust keyboard brightness in low light using the built-in light sensor. One can also adjust keyboard backlight settings manually using hotkeys on the keyboard.
You can find settings to automatically turn off keyboard backlight after a certain period of inactivity by opening Boot Camp Control Panel. To open it, right-click on the Boot Camp icon in the system tray and then click Boot Camp Control Panel option.
Microsoft Surface users can use Alt + F2 to increase the keyboard brightness and Alt + F1 to decrease the brightness.
OEMs such as HP, Asus, and Toshiba don’t offer settings to adjust keyboard brightness.
