How to Check Modern Standby Support on Windows 11

This guide helps you figure out if your computer uses Modern Standby in Windows 11.

Why check for Modern Standby?

Modern Standby (or S0 Low Power Idle) is a smart sleep mode. It keeps your computer connected to the internet while using very little power. This allows your laptop to wake up instantly, just like a smartphone. It also lets your apps receive updates even when the screen is off.

What happens when you are done?

You will know if your hardware is built to handle this “always-on” power feature. If it is not supported, your computer will use the older “S3” sleep mode instead.

How to check your sleep mode

You can check your power settings with a quick command. Follow these steps:

1. Click the Start button and type “Terminal” or “Command Prompt”.
2. Right-click the app and select Run as administrator. (Admin privileges required)
3. In the window that opens, type the following command and press Enter:
4. powercfg -a

The system will show a list of sleep states. If your device supports Modern Standby, you will see “Standby (S0 Low Power Idle) Network Connected” listed.

If your device does not support it, you will see the older S3 sleep mode listed instead, or a message saying the standby state is not available.

You can also learn more about your system settings by visiting the Windows Terminal Windows documentation page.

Summary

Modern Standby makes your computer feel faster by keeping it ready to use at all times. By running powercfg -a in an administrator command prompt, you can quickly see if your hardware supports this feature. Understanding your power settings helps you manage your battery life and computer performance more effectively.
