How to Check Modern Standby Support on Windows 11
Modern Standby support on Windows 11 can be checked by running a simple command in the Command Prompt.
Modern Standby, also known as S0 Low Power Idle, is a power saving feature that allows your PC to wake up very quickly, much like a smartphone.
This feature, first seen in Windows 8.1, lets your computer stay connected to the internet and receive updates even when the screen is off, while using very little power.
To see if your PC has it, you’ll use the Command Prompt to run the `powercfg /energy` command. This creates a report that tells you if your system supports Modern Standby and points out any problems that might be using too much battery.
You can check Modern Standby support by opening Command Prompt as administrator and typing `powercfg -a`. If you see “Standby (S0 Low Power Idle) Network Connected,” your device uses Modern Standby.
Why check for Modern Standby?
Modern Standby lets your Windows 11 PC stay connected to the internet even when the screen is off, allowing apps to update in the background.
What happens when you are done?
Your hardware will indicate whether it uses the modern S0 state or the older S3 sleep mode. Tools are available to generate a report, showing precisely what wakes your computer. This helps in fixing overheating and battery issues.
How to check your sleep mode
To check if your Windows 11 PC supports Modern Standby—the feature that allows it to wake up fast like a phone—run a command in the Terminal app.
- Click the Start button and type "Terminal".
- Right-click the app and select Run as administrator. (Admin privileges required)
- Type the following command and press Enter:
powercfg -a
If you see "Standby (S0 Low Power Idle) Network Connected," your device is using Modern Standby (the newer, faster wake-up mode). If you see "Standby (S3)," your device uses traditional sleep mode (the older, slower wake-up method).
Troubleshooting battery drain and overheating
If your Windows 11 laptop overheats or drains its battery too quickly, Modern Standby could be the cause. You can run a 'Sleep Study' report using the Terminal to see precisely what's consuming power in the background.
- Open Terminal as administrator. (Admin privileges required)
- Type
powercfg /sleepstudyand press Enter. - Windows will save an HTML file to C:\Windows\System32\sleepstudy-report.html.
Open this file in your web browser to see which apps are preventing your computer from staying in a deep sleep state. You can learn more at the official Microsoft Sleep Study documentation.
Can I disable Modern Standby?
If you're experiencing battery problems, you might want to disable Modern Standby on Windows 11. While possible, this involves editing the system's registry (a critical database of Windows settings). This process requires caution to avoid potential issues.
- Press Win + R, type
regedit, and press Enter. (Admin privileges required) - Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power.
- Look for a value named "PlatformAoAcOverride". If it does not exist, right-click, select New > DWORD (32-bit) Value, and name it "PlatformAoAcOverride".
- Set the value to 0 to disable Modern Standby.
Why does my laptop get hot in sleep mode?
Your laptop might get hot in sleep mode because Modern Standby allows it to run background tasks like updates or syncing, which keeps the processor active.
Summary
Modern Standby offers a quick wake-up for your Windows 11 PC. However, it can drain the battery if background tasks aren't managed. You can check its status or troubleshoot issues with simple commands.
