How to Change Power Button Action in Windows 11 25H2

The power button on your PC doesn’t have to just shut everything down. In Windows 11 25H2, you can customize exactly what happens when you press it—whether that’s putting your PC to sleep, turning off the display, or doing nothing at all.

This is especially useful if you want to avoid accidental shutdowns, improve workflow, or optimize power usage on laptops.

Here’s a complete, updated guide covering all methods—from simple settings to advanced tweaks.

Method 1: Change Power Button Action via Control Panel (Easiest)

This is the quickest and safest way for most users.

Steps:

1- Open the Control Panel by typing Control Panel in the Windows search bar and selecting it from the results.

2- In the Control Panel, click on ‘Hardware and Sound’.

3- Under the ‘Hardware and Sound’ section, click on ‘Change what the power buttons do’ found under ‘Power Options’.

4- On the next page, you’ll see options to customize the power button’s behavior. Find the dropdown menu labeled “When I press the power button”. Here, you can select an action for both ‘On battery’ and ‘Plugged in’ modes. The available options are:

• Do Nothing: The power button will not perform any action when pressed.
• Sleep: Puts your computer into a low-power state while preserving your session.
• Hibernate: Saves your current session to the hard drive and powers off the computer.
• Shut Down: Closes all programs and turns off your computer completely.
• Turn off the Display: Switches off the screen while keeping the computer running.

5- After selecting your preferred actions, click on ‘Save changes’ at the bottom to apply the settings.

Note that the available options may vary depending on your device. For instance, laptop users might also see settings for ‘When I close the lid,’ while some desktop computers may not support certain power states, such as ‘Turn off the display,’ if the hardware does not support them.

Method 2: Use Command Prompt or PowerShell (Advanced)

For power users or admins, you can change settings using powercfg.

Open terminal as administrator

• Search for Command Prompt or PowerShell
• Right-click → Run as administrator

Set action for battery mode:

powercfg -setdcvalueindex SCHEME_CURRENT 4f971e89-eebd-4455-a8de-9e59040e7347 7648efa3-dd9c-4e3e-b566-50f929386280 VALUE

Set action for plugged-in mode:

powercfg -setacvalueindex SCHEME_CURRENT 4f971e89-eebd-4455-a8de-9e59040e7347 7648efa3-dd9c-4e3e-b566-50f929386280 VALUE

Replace VALUE with:

⚠️ After running commands, apply changes with:

powercfg -setactive SCHEME_CURRENT

Method 3: Change Power Button via Registry Editor

This method offers deeper control but should be used carefully.

Steps:

1- Press Windows + R to open the Run dialog box. Type regedit and click ‘OK’ to launch the Registry Editor.

2- Navigate to the following registry path:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft

3- Right-click on the ‘Microsoft’ key, select ‘New’, then click on ‘Key’. Name this new key Power.

4- Right-click on the newly created Power key, select ‘New’, and choose ‘Key’ again. Name this key PowerSettings.

5- Inside the PowerSettings key, create a new key named 7648EFA3-DD9C-4E3E-B566-50F929386280. If this key already exists, you can skip this step.

6- With the 7648EFA3-DD9C-4E3E-B566-50F929386280 key selected, right-click in the right pane, select ‘New’, and then click on ‘DWORD (32-bit) Value’. Name this value ACSettingIndex for plugged-in settings or DCSettingIndex for battery settings.

7- Double-click on the DWORD value you created. In the ‘Value data’ field, enter one of the following numbers corresponding to your desired action:

• Do Nothing: 0
• Sleep: 1
• Hibernate: 2
• Shut Down: 3

8- Click ‘OK’ to save the changes. If you wish to set different actions for plugged-in and battery modes, create both ACSettingIndex and DCSettingIndex DWORD values and assign them accordingly.

Method 4: Use Group Policy Editor (For System-Wide Control)

Best for businesses or shared PCs.

Steps:

1- Open the Local Group Policy Editor by pressing Windows + R, typing gpedit.msc, and clicking ‘OK’.

2- In the Group Policy Editor, navigate to:

Computer Configuration > Administrative Templates > System > Power Management > Button Settings

3- Locate and double-click on ‘Select the Power button action (plugged in)’ to set the action when the computer is plugged in.

4- In the policy settings window, select ‘Enabled’. Then, choose your desired action from the ‘Power Button Action’ dropdown menu.

5- Click on ‘Apply’, then ‘OK’ to save the changes.

6- To set the action when the computer is on battery power, double-click on ‘Select the Power button action (on battery)’ and repeat the same steps.

This method ensures that power button settings remain consistent and cannot be modified by individual users through the Control Panel. It is particularly useful in environments where strict control over system configurations is required.

Note that the Local Group Policy Editor is not available in Windows 11 Home edition. If you are using the Home edition, consider using the Registry Editor or Command Prompt methods instead.
