How to activate or deactivate Modern Standby (S0) on Windows 11

The new low power mode, Modern Standby was introduced by Microsoft with Windows 10 and it is a development of the mode Sleep classic (S3). It offers more advantages than S3, but for various reasons you want to know how to activate or deactivate it Modern Standby (S0) on Windows 11 or Windows 10.
In a recent article I showed what is it Modern Standby and what is the difference to the mode Sleep classical.

Modern Standby (S0) puts your laptop or PC into a dormant state of Sleep with significantly reduced energy consumption, but which allows background running of some services, such as email notifications, messages or alerts from some applications. Exiting this S0 mode is almost instantaneous. Much faster than from the state of Sleep (S3) classic.

Modern Security also comes with some disadvantages for which many users prefer the mode of Sleep classical. With S0 the laptop battery discharges much faster than at S3. It sometimes happens that the laptop heats up slightly when it is in Sleep (S0).

Laptop users' opinions on the new way of standby are divided. It is best to know how to activate or deactivate Modern Standby to choose for yourself which type of Sleep satisfies you the most.

How do you check if Modern Standby (S0) is active?

Before activating or deactivating the modes of Sleep, you must check their availability. Not all laptops support it Modern Standby or Sleep (S3).

powercfg /a
Power Config Sleep States
Power Config Sleep States

If in the mood Sleep available appears Standby (S3) it means that on a laptop or PC it is the mode of Sleep classical. so Modern Standby (S0) is not active.

If the mode is active, it will appear: Standby (S0 Lower Power Idle) Network Connected/Disconnected.

If S0 is activated, on command powercfg /a must also appear Standby (S3): “This standby state is disabled when S0 low power idle is supported” so you can disable it Modern Standby.
There are systems that come directly with Modern Standby without the classic way of Sleep (S3) in firmware. On those systems it cannot be disabled Modern Standby, and the alternative remains to use the mod Hibernate.

To deactivate open Command Prompt on Windows 11 with rights administrator and run the command:

reg add HKLM\System\CurrentControlSet\Control\Power /v PlatformAoAcOverride /t REG_DWORD /d 0
Power Management Disable Sleep S0
Power Management Disable Sleep S0

The operation completed successfully. It means that Modern Standby (S0) was deactivated and activated automatically Sleep (S3) classic.

Modern Standby it is activated with the command:

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

The operation completed successfully.
