How to Disable Modern Standby in Windows 10 & 11: A Complete Guide

Modern Standby, known as S0 Low Power Idle, is a power-saving feature introduced in Windows 10 and fully integrated into Windows 11. This functionality allows devices to maintain a connection to networks and continue to perform background tasks while using less power. However, for some users, this can lead to unexpected battery drain and delays in waking the computer. Therefore, many users seek methods to disable Modern Standby in favor of the older S3 Sleep mode. In this article, we'll explore how to disable Modern Standby in Windows 11 and Windows 10 and delve into the various ACPI power states that Windows employs.

Understanding Modern Standby​

Modern Standby represents a significant change from traditional power management techniques. Unlike the conventional S3 Sleep mode, where the computer effectively enters a deep sleep and temporarily halts most processes, Modern Standby allows the system to remain partially active, consuming less power while still being able to connect to the internet for updates and notifications. This feature is particularly beneficial for devices that require instant wake capabilities, such as laptops and tablets. Many users have reported that while the fast wake and continual connectivity are advantages, the trade-off can be detrimental in the form of higher battery consumption. Consequently, disabling Modern Standby can help those who prefer the efficiency of the S3 mode.

Methods to Disable Modern Standby​

There are several methods to disable Modern Standby, which include using Windows PowerShell, editing the Windows Registry, or employing a REG file for automated changes.

Method 1: Using Windows PowerShell​

1. Open Windows Terminal: Right-click the Start menu and select “Windows Terminal (Admin)”.
2. Check Power Sleep States: To see the currently supported sleep states on your device, enter the following command:
   Code:

    powercfg /a

   Look for "S0 Low Power Idle" in the output.
3. Delete the Registry Key to Enable Modern Standby: To ensure Modern Standby is enabled, use the command:
   Code:

    reg delete "HKLM\System\CurrentControlSet\Control\Power" /v PlatformAoAcOverride /f

4. Add the Registry Key to Disable Modern Standby: If you want to disable it, use this command:
   Code:

    reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0

   Method 2: Editing the Windows Registry​

   If you prefer interacting directly with the Windows Registry, follow these steps:
5. Open Registry Editor: Type "regedit" in the Start menu and press Enter.
6. Navigate to the Power Key: Go to:
   Code:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power

7. Create a New DWORD (32-bit) Value: Right-click on the right pane, select “New” > “DWORD (32-bit) Value,” name it PlatformAoAcOverride.
8. Modify the Value: Double-click the newly created DWORD and set its value to 0 to disable Modern Standby or 1 to enable it.

   Method 3: Using a REG File​

   For those who would like an automated way to change settings, a REG file can simplify the process.
9. Download the REG File: Obtain a zipped REG file that contains the necessary commands.
10. Merge the REG File: Unzip the file and double-click it. Confirm the security warning to apply the registry changes.
11. Restart Your Computer: Finally, restart your PC to ensure the changes take effect.

    Overview of Windows ACPI Power States​

    Understanding the ACPI (Advanced Configuration and Power Interface) power states is crucial for managing power consumption and optimizing your system's energy efficiency:
    • G0 (S0 – Active State): The system is fully operational, running tasks normally.

• G1 (Sleeping States): Several sleep modes fall under this category, including:
  • S0 Low Power Idle (Modern Standby): Allows devices to stay connected for updates and notifications while in a low-power state.
  • S3 (Suspend to RAM): Powers down most components except RAM, which retains the system state. Waking from S3 is quicker than from a full shutdown.
  []G2 (Soft Off): The system is turned off, but components can still respond to wake signals. []G3 (Mechanical Off): The system is entirely powered down and requires manual restart.

  Why Disable Modern Standby?​

  Users may choose to disable Modern Standby for various reasons: []Battery Management: Users observing significant battery drains may find disabling this feature an effective solution. []Performance Issues: Some users have reported slower system performance or compatibility issues with certain hardware when Modern Standby is enabled. []Preferential Sleep State: Many prefer the traditional S3 mode which offers more energy savings since it fully powers down most components.

  Conclusion​

  Disabling Modern Standby can help users regain control over their system's power consumption and overall performance. By utilizing the methods described above, Windows users can effectively modify their power settings according to their preferences. Understanding the various ACPI power states can also provide insight into how Windows manages devices during periods of inactivity, further aiding users in optimizing battery life and performance.

  Key Points Summary​

  []Modern Standby — A power-saving feature in Windows 10 and 11 that allows background activity in a low-power state. []Disabling Methods — Users can disable it using Windows PowerShell, via Registry Editor, or by using a REG file for convenience. []ACPI Power States — Essential for understanding system energy management, including G0, G1 (sleep states), and G2/G3 (soft off and mechanical off).

By considering these options and insights, users can tailor their device’s power management to suit their needs, ultimately enhancing their overall experience with Windows. Source: WinBuzzer How to Disable Modern Standby in Windows 11 and Windows 10
