- Does your Windows 11 PC shut down instead of going to sleep? Don't sweat it as you are not the only one.
- As a first solution, you should check your power settings to see whether sleep mode is activated.
- Check the BIOS settings as well, and make sure that the Power Saving mode is turned on there.
Sleep mode is often regarded as one of the most beneficial aspects of the Windows operating system, particularly when it comes to reducing power usage.
The mode places your device in a low-power state, turns off the display, and allows you to resume your work from the point where you left off last time. Because of this, Windows employs the sleep mode rather than entirely turning off the system to conserve battery life on your device.
When you’re away from your computer for a short period, you should use this feature to prevent your power supply unit from overheating as a result of prolonged use.
However, some users reported that their PC won’t enter sleep mode and will either shut down completely or do nothing. Follow along as we have put together a list of solutions for this issue right after we see what the differences between sleep and hibernation modes are.
What are the differences between sleep and hibernation mode?
Sleep mode and hibernate are frequently used interchangeably by the majority of people but they are not the same thing in reality.
The former is a power-saving mode that allows activities to restart once the device is completely charged again, while the latter mode, like Sleep mode, is intended to conserve power, but it differs in terms of what happens to your data.
While in sleep mode, the documents and files that you are now working on are stored in the RAM, requiring only a minimal bit of power in the process.
Hibernate mode effectively accomplishes the same thing, except it stores the information on your hard disk, allowing you to power off your computer and saving all of the energy it would have consumed.
When you turn your computer back on, the hard drive allows you to pick up precisely where you left off with your work. Hibernate is primarily intended for laptop computers, and it is most effective when you are not planning to use your computer for an extended amount of time.
Once again, laptops are most suited for sleep mode due to their battery life, which allows them to last through both brief naps and overnight slumbers. It should be mentioned that if your computer is left unattended for an excessive amount of time, it will shut down.
What can I do if Windows 11 won’t go to sleep mode?
1. Enable sleep mode manually
- Press the Windows key + I to open the Settings app, and navigate to System in the left panel followed by Power & battery from the right side.
- Now scroll to the Screen and sleep section and set manually the time interval of inactivity after which you want your PC to enter sleep mode.
2. Change when the computer sleeps
- Press the Windows + S key to open the Search bar, then type Choose a power plan and click on the most relevant result.
- Now click on Choose when the computer sleeps from the left panel.
- Lastly, choose when you want your computer to go into sleep mode then click Save.
3. Perform a virus scan
- Click the carrot arrow from your taskbar, in the right corner to find the antivirus you have installed, then right-click on it and choose the option that opens the app interface.
- Now click on the button that performs a Smart scan or anything similar to a virus scan.
The existence of a virus or malicious software on your computer can prevent your device from entering sleep mode.
In case you don’t have antivirus software and want to ensure that your PC is protected around the clock without any effort from your side, we recommend that you try out the powerful ESET Internet Security.

4. Turn off Screensaver mode
- Press the Windows + S key to open the Search bar, then type Turn screensaver on or off and click on the most relevant result.
- Now choose None under Screen saver, then click OK.
5. Remove the battery
This step applies to both users that are using a laptop or desktop computer. If your PC frequently refuses to sleep, even though all of the settings are proper, the most likely culprit is the battery itself.
Removing the CMOS battery for 15 minutes and reinserting it to see if the problem has been resolved is recommended. Alternately, the CMOS battery should be replaced.
If your device’s battery is not replaceable, you can use a third-party app to keep track of how much power it has left before deciding to replace it.
How much power does a computer use in sleep mode?
Almost everyone has access to a computer, whether for personal or professional reasons. Computers are well-known for consuming a significant amount of electricity, particularly while performing certain tasks like playing video games or using photoshop.
As a result, it is recommended that we minimize our power usage to the bare minimum while we are not using them. It is for this reason that we have a sleep mode. When the computer is in sleep mode, though, how much power does it use up?
In sleep mode, most computers typically require between 3 and 10 watts of power. When the desktop computer is operating in regular mode, it consumes 60 to 300 watts of electricity, which is approximately 30 times more than when it is operating in sleep mode.
Laptops, in contrast to computers, utilize approximately 2 watts of electricity when in sleep mode. When the computer is in sleep mode, all of its devices, except for the RAM, are powered down.
Another issue to consider is the number of applications that are operating on your computer at any given time. If your computer is not running many applications, you can put it into sleep mode, which will prevent the display, disk, and other key power consumers from using any power.
