windows 10 won't stay in sleep mode

The elementary part of Windows systems is the Sleep mode. Instead of turning their PC every time, the majority of users will put it to sleep to reduce the power consumption and let it cool down while retaining the speedy access to their system. However, there seems to be an issue with the Sleep mode in Windows 10. Namely, even though they’re able to put their PC to sleep, the PC keeps on waking up without any interaction on their side. Basically, it refuses to stay in the Sleep mode as intended — until you decide to use it.

We made sure to look into this and provide you with some essential troubleshooting steps. If you’re affected by this issue, make sure to check the solutions we enlisted below.

Can’t put a PC to sleep? Here’s how to fix this

  1. Run the troubleshooter
  2. Check the drivers
  3. Disable specific devices from waking up your PC
  4. Check the Advanced Power options
  5. Disable Fast Startup and prevent programs starting with the system
  6. Use Hibernation instead of Sleep
  7. Reset your PC to factory values

1: Run the troubleshooter

Firstly, let’s make sure you’ve enabled Sleep mode properly. Follow the steps we provided below to confirm that the Sleep mode is indeed properly configured.

  1. Right-click on the Batter icon in the Taskbar’s notification area and open Power Options.
  2. Click “Change plan settings” on your active Power plan.windows 10 won't stay in sleep mode
  3. Under the “Put the computer to sleep” section, make sure to set the time for PC to go to Sleep.

Secondly, let’s try and tackle this bug with the built-in Power troubleshooter found in the system settings. This troubleshooter should fix all bugs in the power configuration and allow you to put your PC to sleep without waking up by itself.

Follow these steps to run the Troubleshooter:

  1. Press Windows key + I to open Settings.
  2. Choose Update & Security.windows 10 won't stay in sleep mode
  3. Open Troubleshoot from the left pane.
  4. Expand the Power Troubleshooter and click “Run the troubleshooter“.windows 10 won't stay in sleep mode

2: Check the drivers

We also need to confirm that all drivers are properly installed. Lots of reports point towards the Realtek sound drivers which were causing the system wake-up without reason. So, navigate to Device Manager and update all major driver, with special emphasis on Display, Sound, and Network devices.

Even if the drivers are seemingly up to date, we still recommend navigating to the official manufacturer’s site and downloading proper drivers. This goes especially for legacy devices which are known to have issues with Windows 10.

3: Disable specific devices from waking up your PC

There’s a way to find which exact device is waking your device and tweak its settings or even unplug it. There are probably some third-party applications which might help with this, but we’ll stick with the Command Prompt for the time being. With a few commands, you can determine all power usage and access the peripheral devices have on the system.

Here’s what you need to do:

    1. Right-click on the Start and open Command Prompt (Admin).
    2. In the command-line type the following command and press Enter:
      • Powercfg -devicequery wake_armedwindows 10 won't stay in sleep mode
    3. This command will list all devices which can wake the PC from sleep.
    4. Now, if you see the device you don’t use, type in the following command and press Enter. Don’t forget to change the device name.
      • Powercfg -devicedisablewake “devicename”
    5. Close the elevated Command Prompt and restart your PC.

4: Check the Advanced Power options

We also suggest resetting all advanced power options to default values. This should resolve some of the issues possible misconfigured advanced options have on your active Power plan. Just don’t forget to set the Sleep mode preferences after this step.

Here’s how to reset Advanced Power options to default values:

  1. Right-click on the Battery icon in the notification area and open Power options.
  2. Click “Change plan settings” on your active power plan.
  3. Click Change advanced power settings.
  4. Now, just click Restore plan defaults.windows 10 won't stay in sleep mode

5: Disable Fast Startup and prevent programs starting with the system (mention AV)

Furthermore, we suggest disabling the Fast Startup feature. It’s known that this newly-introduced (relatively new) feature is the possible culprit for the system’s inability to go to sleep without waking every now and then without any reason.

Here’s how to disable it in a few steps:

  1. Right-click on the Battery icon in the notification area and open Power options.
  2. Click on the “Choose what the power buttons do” hyperlink in the left pane.windows 10 won't stay in sleep mode
  3. Click “Change settings that are currently unavailable“.
  4. Uncheck the “Turn on fast startup (recommended)” box.windows 10 won't stay in sleep mode
  5. Shut down your PC and power it on again.
  6. Look whether the PC wakes from sleep again.

Also, we recommend disabling all startup third-party programs and their dedicated services in a sequence commonly known as Clean Boot. Follow these instructions to apply Clean Boot to your system:

  1. In the Windows Search bar, type msconfig and open System Configuration.
  2. Under the Services tab, check the “Hide all Microsoft services” box.
  3. Click “Disable all” to disable all active third-party services.windows 10 won't stay in sleep mode
  4. Now, select the Startup tab and go to Task Manager.
  5. Prevent all programs from starting with the system and confirm changes.
  6. Restart your PC.

If you’re unable to disable the antivirus, we suggest uninstalling it for the time being. After you determine which application is causing waking, you can install it again.

6: Use Sleep-Hibernation hybrid instead of Sleep

Even though it’s not the same, behavior-wise, the Sleep-Hibernation mode can be a worthy replacement. At least, until you find an alternative to re-enable the Sleep mode which will work as intended. This mode is, as the name itself points out, the cross between Sleep and Hibernate.

Follow these steps to replace the Sleep mode with the Hibernation mode in the Advanced Power settings:

  1. Right-click on the Battery icon in the notification area and open Power options.
  2. Click “Change plan settings” on your active power plan.
  3. Click Change advanced power settings.
  4. Expand Sleep and then Allow Hybrid sleep.windows 10 won't stay in sleep mode
  5. Turn Hybrid sleep on for both Battery and AC and confirm changes.

7: Reset your PC to factory values

In the end, if none of the aforementioned suggestions fixed your issue with the Sleep mode, we have only one recommendation remaining. And that’s, for better or worse, resetting your PC to factory values. This is more of a refresh for your system than a reinstallation. Moreover, as the most reports state that the issues emerged after an update, you should resolve this with this recovery option.

These instructions should show you how to reset your PC to factory values:

  1. In the Search bar, type Reset and open Reset this PC.
  2. Under the ‘Reset this PC‘ option, click Get started.windows 10 won't stay in sleep mode
  3. Choose to retain your files and apps and continue with the resetting process.

With that said, we can conclude this article. Hopefully, with these steps, you were able to resolve the issue at hand. We encourage you to share your experience with the issue or provide some alternative solutions. You can do so in the comments section below.
