Why Is Sleep Mode Not Working in Windows 11?

Windows 11 may refuse to enter sleep mode for several reasons. A background app, connected USB device, outdated driver, or incorrect power setting can keep your computer awake.

Sometimes the issue appears after a Windows update or driver change. In other cases, your PC may enter sleep mode but wake up immediately because of a network adapter, keyboard, mouse, or scheduled task.

The good news is that most sleep problems can be fixed without reinstalling Windows.

How to Fix Windows 11 Sleep Mode Not Working

1. Check Sleep Settings

Start by making sure Windows is actually configured to go to sleep.

Go to:

Settings → System → Power & battery → Screen, sleep & hibernate timeouts

Check the sleep options and choose a suitable time for your PC to enter sleep mode.

If the sleep timer is set to Never, Windows will not automatically put the computer to sleep.

2. Restart Your PC

Before changing advanced settings, restart your computer. A background process may temporarily prevent Windows from sleeping.

Click:

Start → Power → Restart

After Windows starts again, close unnecessary applications and try putting your computer to sleep.

If Sleep works after restarting but stops working later, a background application or device could be responsible.

3. Check Which App Is Preventing Sleep

Windows includes built-in commands that can help identify processes or drivers preventing sleep.

Open Terminal or Command Prompt as Administrator and run:

powercfg /requests

Windows will show active requests that may be preventing the computer from entering sleep mode.

If an application or driver appears in the results, close the related program or update the associated driver.

4. Disconnect Unnecessary USB Devices

A faulty or incorrectly configured USB device can sometimes prevent your PC from sleeping.

Disconnect devices such as:

• USB storage drives
• Game controllers
• Printers
• External webcams
• USB hubs
• Other unnecessary accessories

Then try Sleep again.

If sleep starts working, reconnect the devices one at a time to find which one is causing the problem.

5. Check Keyboard and Mouse Wake Settings

Your keyboard or mouse may be waking the computer immediately after it enters sleep mode.

Open Device Manager and expand:

Keyboards or Mice and other pointing devices

Right-click the relevant device and select Properties.

Look under the Power Management tab. If available, review the option that allows the device to wake the computer.

You can disable wake permission if the device is causing unwanted wake-ups.

6. Update Your Drivers

Outdated or incompatible drivers can interfere with Windows power-management features.

Pay particular attention to:

• Chipset drivers
• Graphics drivers
• Network drivers
• USB drivers
• BIOS or firmware

Open Settings → Windows Update → Advanced options → Optional updates and check whether driver updates are available.

You can also download drivers directly from your computer or motherboard manufacturer’s official website.

7. Check Network Adapter Wake Settings

A network adapter can sometimes wake your PC from sleep.

Open Device Manager and expand:

Network adapters

Right-click your Wi-Fi or Ethernet adapter and select Properties.

Open the Power Management tab and review the wake-related settings.

If your computer repeatedly wakes shortly after sleeping, disabling unnecessary wake permissions for the network adapter may help.

8. Restore the Default Power Plan

Incorrect power-plan settings can cause sleep-related problems. Restoring the default settings is worth trying if you have previously changed advanced power options.

Open Control Panel and go to:

Hardware and Sound → Power Options

Select your current power plan and choose Change plan settings.

Then select Restore default settings for this plan if the option is available.

Afterward, restart your PC and test Sleep mode again.

9. Run the Power Troubleshooter or Repair Windows Components

If Sleep still does not work, check Windows for system problems.

You can start by opening Settings → System → Troubleshoot → Other troubleshooters and reviewing the available troubleshooting tools.

If you suspect corrupted Windows system files, open Terminal as Administrator and run:

sfc /scannow

Allow the scan to finish and restart your computer afterward.

For more serious system-component problems, the DISM tool can also be used to repair the Windows component store.

What If Windows 11 Sleep Mode Is Still Not Working?

If your PC still refuses to sleep, check whether it is not sleeping at all or sleeping and immediately waking up. These are slightly different problems.

If Windows never enters sleep, an application, driver, power setting, or connected device may be blocking the sleep request. The powercfg /requests command can help identify the problem.

If your PC sleeps but wakes up by itself, check your keyboard, mouse, network adapter, scheduled tasks, and wake timers.

You should also check for recent Windows or driver updates. If the problem started immediately after an update, installing a newer driver or checking available Windows updates may resolve the issue.
