This article covers the Modern Standby feature on Windows 10, what it is and how to check PC compatibilityModern Standby is a new iteration of Connected Standy launched back with Windows 8. Modern Standby expands the Connected Standby from Windows 8 to Windows 8.1 and Windows 10.

Modern Standy puts the system in a low power mode or in a sleep state while keeping some service active in the background. The Connected Standby has only Connected mode, Modern Standby supports Connected as well as Disconnected Mode. In the Connected Modern Standby mode, the system stays connected to the network and can get emails, messages, etc while on standby. Whereas, in Disconnected Modern Standby mode, the system disconnects from the network as well which leads to even lesser battery consumption.

These modes of Modern Standby are dictated by user configuration or by hardware. A system in Modern Standy (S0) is capable of the following scenarios:

  • Instant On
  • Background activity
  • Simplified wake story (with a hardware interrupt)

How does it work?

connected standby vs modern standby

The Modern Standy is made possible with the S0 power mode in the modern hardware. S0 power mode is a newer iteration of S3 power mode used for legacy standby. S0 power mode put the system in a low power idle state while keeping some background services running such as networking, disk services, etc.

When you put a system into Modern Standby mode, the OS prepares the hardware as well as software for a low-power state. During this mode, Windows stays in an idle state and goes to an active state for a short span of time to perform kernel maintenance tasks. The same happens in case of networking as well. If there is incoming traffic (incoming email, text, etc.), the networking hardware goes in an active state otherwise it stays in an idle state. Also, when the system receives an input, it almost instantly comes online and restores all the idle state to active.

Check if your Windows PC Compatibility with Modern Standby

To check if your Windows PC compatibility with Modern Standby, open Command Prompt with Administrator privileges and execute the following command:

powercfg /availablesleepstates

modern standby compatibility check

This command shows the available sleep states on your Windows PC. As you can see in the screenshot attached above, my PC supports the S1 and S3 sleep states and lacks the S2 and S0 state. Lack of support for S0 sleep mode means my PC is not compatible with Modern Standby mode.

Closing Words

Modern Standby is a newer iteration of sleep mode that can run services in the background in low power state. It allows you to save battery while not working and yet won’t let you miss an email. If your PC is compatible with Modern Standby (with S0 sleep state), it’s activated by default and you can configure it from Power and Sleep Settings or BIOS.
