How to check supported power status on Windows 11

Windows 11 can handle many different power states. Here's how to check the supported power status on a usable Windows 11 computer.

How to check supported power status on Windows 11

Most PC users know the common power states such as On, Off, Sleep and Hibernate. However, computers can handle power in many ways. Understanding these power states can help you understand how your PC works and provide you with some more useful ways to use your computer.

However, not all power states are available on the computer. You need to check the available power status based on the hardware.

How to check available power status in Windows 11

You can find the available power statuses on your computer using Command Prompt.

  1. Click Start Menu, type cmd , point to Command Prompt and select Run as administrator .
  2. Enter the following command and press Enter :
powercfg /availablesleepstates

You will see two lists of power statuses. One is the list of supported power states, the other is the unsupported power states.

How to check supported power status on Windows 11

All Windows 11 power states

S0: Working State

S0 represents working status. This is the state of the computer when you can use it.

S0 Low-Power Idle: Sleep (Modern Standby)

Modern Standby is an upgrade to the S3 source model. It allows you to turn on devices faster than S3, providing a seamless experience when using a modern device. This mode is typically supported on System on Chip (SoC). However, there are still exceptions. If your computer supports S0 low power idle mode, it will not support S1, S2, or S3 mode.

S1, S2, S3: Sleep Power States

The “Sleep” state is where one or more components on the computer are turned off or go into low power mode.

Sleep power state S1 stops the CPU, the rest of these components are turned off or continue to run in low power mode, and RAM maintains power.

The sleep power state S2 stops providing power to the CPU, other components are turned off or continue to run in low power mode, and RAM maintains power.

S3 is a standby state where the CPU has no power, but RAM maintains power and refreshes it at a low rate. Other hardware components such as hard drives and fans will temporarily stop operating.

Your device may also support “Hybrid sleep” mode. Here, you can save this session. If the computer loses power while in sleep mode, you can continue what you just left off.

S4: Hibernate

This mode is different from Sleep because hibernation saves the contents of RAM and operating system state to the hard drive and turns off the power of all connected devices. When you turn your computer back on, you can directly start work from where you left off before going into hibernation.

S5: Soft Off Power State

S5 is the “soft off” state. Only components like the power button have a trickle of current. No other components draw power in this state, and the computer is not performing any computational tasks.

G3: Mechanical Off

Shutdown state is also the state where the computer is completely turned off like in S5. However, the power supply is completely removed via a mechanical switch. No power to any hardware components, including the power button. This state is usually only necessary when you want to disassemble the computer. Note that the real-time clock can still continue to run using a small battery.

Above are the things you need to know about the power status on your computer . Hope the article is useful to you.
