Windows 11 now lets you change the default keyboard backlight percentage when using Energy Saver mode. Here’s how to do it.
When using Energy Saver mode in Windows 11, the operating system does several changes to the power settings of your computer and limits background processes so that it uses less power and increases battery life on your laptop. To put it simply, Energy Saver mode prioritizes reducing power consumption at the cost of performance. One such optimization Windows does is reduce the backlight brightness. By default, it reduces to 70%.
By making a small registry change, you can control how much Windows lowers the backlight brightness. For instance, setting it to 50% will make Windows further dim the keyboard backlight, while setting it to 100% will restore full brightness. By setting the default backlight percentage for Energy Saver mode according to your specific requirement, you reduce the need to manually change the backlight brightness often.
So, without further ado, let me show you how to change or set a default keyboard backlight percentage when using Energy Saver mode in Windows 11. Let’s get started.
Before You Start
- This guide requires editing the Windows Registry. Before proceeding, please back up the registry.

Detailed Steps (With Screenshots)
Since we must edit the registry, open it first. Press the “Windows key + R“, type “regedit“, and click “OK“. This opens the Registry Editor.
In it, go to the “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Lighting\Backlight” folder. You can either navigate manually on the left sidebar or paste the path in the registry’s address bar and press “Enter”.
Now, see if you have the “BacklightEnergySaverMultiplier” value on the right panel. If you don’t, right-click the “Backlight” folder on the left panel, select “New,” and then “DWORD (32-bit) Value“.
Name the value as “BacklightEnergySaverMultiplier“.
Next, double-click the value and enter a value between 0 and 100, then click “OK“. For example, if you want the keyboard to be completely dim, enter 0. For full brightness, enter 100. Or, you can set any other value according to your requirement.
Close the Registry Editor and restart your computer. After restarting, whenever you are using the Energy Saver mode, Windows automatically sets the keyboard backlight to the brightness you set in the registry.
To reset this change, you can either delete the “BacklightEnergySaverMultiplier” value or change its value data to 70.
