How to Disable Connected Standby Network Activity in Sleep

What Causes This?

On many modern Windows laptops, Connected Standby or Modern Standby keeps parts of the system active even while the PC appears to be asleep. That can allow Windows, apps, and services to maintain network access for syncing mail, notifications, updates, and background tasks.

This behavior is usually controlled by your device’s power model, Windows power settings, and sometimes Group Policy or registry settings. On supported hardware, Windows may keep Wi-Fi active during sleep by default, which increases background activity and can expose the device to unnecessary network communication while it should be idle.

Common Symptoms

• Your laptop loses more battery than expected while sleeping
• Email, cloud storage, or app notifications update while the PC is asleep
• Wi-Fi or network activity lights continue blinking during sleep
• The PC feels warm after being asleep in a bag or on a desk
• Sleep reports show background tasks or network usage during idle time

How to Fix It Manually

1. Check whether your PC uses Modern Standby

   1. Press Windows + X and select Terminal (Admin) or Windows PowerShell (Admin).
   2. Type:

      powercfg /a

   3. Look for Standby (S0 Low Power Idle) in the list. If you see it, your PC uses Modern Standby and may allow network activity during sleep.

2. Change network connectivity settings in Power Options

   1. Press Windows + R, type control, and press Enter.
   2. Go to Hardware and Sound > Power Options.
   3. Click Change plan settings next to your active power plan.
   4. Select Change advanced power settings.
   5. Expand Sleep > Network connectivity in Standby.
   6. Set it to Disable for On battery and Plugged in, if available.
   7. Click Apply, then OK.

3. Use Group Policy if the setting is missing

   1. Press Windows + R, type gpedit.msc, and press Enter.
   2. Go to: Computer Configuration > Administrative Templates > System > Power Management > Sleep Settings
   3. Open Allow network connectivity during connected-standby (on battery).
   4. Set it to Disabled, then click Apply.
   5. Do the same for Allow network connectivity during connected-standby (plugged in).

4. Use the registry on Windows Home if Group Policy is unavailable

   1. Press Windows + R, type regedit, and press Enter.
   2. Navigate to:

      HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Power\PowerSettings

   3. If needed, create the missing keys under this path for the sleep policy used by your device.
   4. Because registry paths for sleep policies can vary by hardware and Windows version, back up the registry first with File > Export before making changes.
   5. Restart the PC after any registry change.

5. Disable wake-capable network adapters if needed

   1. Press Windows + X and choose Device Manager.
   2. Expand Network adapters and double-click your Wi-Fi adapter.
   3. Open the Power Management tab.
   4. Uncheck Allow this device to wake the computer if it is enabled.
   5. Click OK.

6. Verify the result

   1. Put the PC to sleep from Start > Power > Sleep.
   2. Wake it after a few minutes and open Terminal as admin again.
   3. Run:

      powercfg /sleepstudy

   4. Review the report to confirm network activity during sleep has been reduced.
