If you find that your Windows 10 has problems with Sleep mode, this article will give you a solution.

In addition to Hibernate, Sleep is the option that most computer users use to save power when they need to leave the machine and can quickly resume their unfinished work at any time.

However, if for some reason your computer suddenly “wakes up” or switches to Sleep mode at random even if there is no effect from yourself or anyone else then what to do? Please refer to the following.

Check the settings of Sleep mode

In case the computer cannot switch to Sleep mode, please check the Sleep related settings from Power Options because it may have been accidentally changed to prevent Windows from switching to Sleep.

Specifically, right-click the Start button and click Power Options from the menu that appears.

The Settings window appears and automatically accesses the Power & sleep settings page, find and click the Additional power settings option.

Then, the Power Options window in Control Panel appears, click the Choose when to turn off the display option.

The settings page of the option has appeared, consider the settings to see if it is different from before, especially Put the computer to sleep. Usually if the computer suddenly switches to Sleep mode or the transfer process takes a long time, this is the item you need to consider first.

Disable the Fast Startup feature on the old computer

If you don’t know, Fast Startup in Windows 10 is an installation that helps your computer boot faster after turning off the computer. Fast Startup will save the kernel image and load the driver into C: hiberfil.sys when the computer is turned off. When you turn off and restart the computer, Windows will reload the hiberfil hibernate file into memory so that the computer continues to work with previously manipulated tasks.

Often, Fast Startup works well on new computers or has a strong hardware configuration, but it is a “burden” for older computers. And there are cases where it also makes the computer unable to switch to Sleep mode when the user requests it.

Therefore, if you determine that the computer you are using is old, please disable Fast Startup as follows.

Go to Power Options like previous option and click on the Choose what the power buttons do option.

The setting interface of this option appears, click the Change settings line that are currently unavailable.

Then uncheck the Turn on Fast Startup option and click Save changes to save it.

Check and update the driver

Although it doesn’t sound relevant, sometimes the driver itself is the reason Windows 10 can’t switch to Sleep mode or make Sleep mode not really stable as it was set up. Therefore, timely checking and updating drivers may help you fix the problem with Sleep mode.

You can perform a driver check for your computer using http://www.nirsoft.net/utils/driverview.html which is provided free of charge from Nir Sofer to review the version and update it from the main manufacturer’s homepage.

You can also perform automatic updates via Device Manager available on Windows 10.

Launch the Power Troubleshooter tool

Windows itself is also equipped with a list of tasks to check and fix the basic problems of the system, including tasks related to Sleep mode. And maybe, when you use the Power Troubleshooter auto-checking and troubleshooting task, what about the problem with Sleep mode? Please try the following.

Go to Settings> Update & Security> Troubleshoot.

In Troubleshoot, go to the Power section and click, click Next Run the troubleshooter below. Then, automatic error detection and correction will start.

If you’re lucky, your Sleep problem will be fixed with Power Troubleshooter.

Restore power settings to default

In case, if you upgrade Windows 10 manually, it is possible that the power settings will be stacked on each other, causing problems with the resting modes of Windows 10, not just Sleep. Therefore, you should try to restore the power settings to default to check if the problem happens again.

Visit the Power Options as shown above and click on the Choose when to turn off the display option. Then click on the Restore default settings line for this plan.

The confirmation dialog box appears, click Yes and wait for the restore process to complete.

Check and disable the Screensaver feature

In some cases, if you use the Screensavers feature, it is possible that setting this feature causes the computer to switch to Sleep mode at random. Therefore, please check and disable it in the following way.

Enter the “screen saver” keyword in the search bar and click the result as shown.

The Screensaver window appears, set as shown and click Apply> OK to save.

Restore to the default interface of Windows 10

Many third-party themes on the Windows Store can contain settings that make the computer automatically switch to Sleep at random times.

Therefore, try to restore the default interface of Windows 10 to check if the problem is resolved.
