If a Windows 10 user needs to turn off the computer, but does not want to end the current session, then he usually uses such a wonderful feature as sleep mode. Since neither running programs nor open files are closed when going into sleep mode, you can continue working with them immediately after turning on the computer, which is very convenient.
But in some cases, due to various types of errors, the computer does not wake up from sleep mode, and it has to be forced to reboot, which is why data is lost. There are not so many reasons for this occurrence, but it is often not immediately possible to find the source of the problem. When considering this malfunction, we mean not only the classic sleep mode, in which the computer is put into a state of reduced power consumption, but also hibernation and the so-called hybrid sleep mode.
Problems with peripherals
Check to see if the option in your keyboard settings is enabled to allow the device to wake up your computer from sleep (standby) mode. To do this, in Device Manager, double-click on the keyboard and go to the “Power Management” tab.
The corresponding option should be checked. The same steps should be done with the mouse and network adapters. With some caution, you can try the opposite - uncheck this option and test the sleep mode without it.
Driver problems
Missing or incorrectly working device drivers are another cause of sleep problems. This is especially true for video card software, malfunction of which sometimes leads to the computer not waking up from sleep mode, or after exiting, a black screen remains and the desktop never loads. The recommendations in such cases are simple - you should check whether all drivers are installed and whether they are all functioning normally. Outdated drivers should be updated, but if a problem with sleep mode appeared after updating them, you need to roll back to the previous version.
Software conflict
Third-party power management applications may interfere with normal sleep mode operation. Remove such managers and all suspicious programs from your computer, especially those with Adware status. If you have a laptop, you might want to get rid of the vendor-installed software as well.

Updates
If Windows 10 does not wake up after installing updates, you should remove them. Although updates are useful, sometimes they contain errors that lead to a variety of problems with the operating system. You can also try rolling back the system to the last restore point - this method is often effective for various malfunctions.
Changing BIOS settings
If none of the above methods helped and Windows 10 does not wake up after sleep mode, then you will have to reset the BIOS settings. It is worth noting that this method is only suitable for experienced users who have been working with computers for many years.
Changing settings in the BIOS is one of the ways you can get rid of problems with waking up your PC
First you need to figure out how to enter the BIOS. To do this, you need to restart the PC and immediately after starting, quickly start pressing the Del or F10 key.
After this, a menu will appear on the screen in which you can change system parameters. You need to find the “Power” subsection in it. Here you need to activate the “ACPI” parameter and restart the PC.
In rare cases, the BIOS is password protected. You can find it in the instructions for the motherboard or on the manufacturer’s official website.
Hibernate file corruption
A radical way to solve the problem with sleep mode not working correctly is to recreate the hibernation file hiberfil.sys if it suddenly becomes damaged. Deleting a file is done as follows. Open a command prompt or PowerShell console as an administrator and run the command powercfg -h off .
Then, having turned on showing hidden and system files, go to the root of the C drive and make sure that the hiberfil.sys file no longer exists. If it remains, remove it manually. After completing these simple steps, enable hibernation mode with the command powercfg -h on .
Check your sleep settings
When your computer won't go to sleep, check any settings and factors that are interfering with your sleep state. Hardware, power settings, and configuration can affect the operation of the power and sleep buttons. If your computer has updates installed or an application installed that requires a restart, then your computer may not sleep at all.
If you are working on a shared computer or on a computer that is not yours, there is a chance that someone else may have adjusted the power settings. To access these settings, go to Control Panel > Power Options and click Choose when to turn off your display .
Just on the right side of Put your computer to sleep , check the values and make sure you set them up correctly. If your computer is going to sleep too early or takes too long to fall asleep, this should be your first port of call.
Award BIOS settings failure
Finally, as a last resort, we recommend checking your BIOS configuration, since a failure in its settings could very well result in your Windows 10 PC not waking up from sleep mode. True, the method described below is only suitable for Award BIOS; if you have a more modern version of the BIOS, for example, AMI or UEFI, skip this step.
Once in the BIOS, find the “Power Management Setup” section (it may simply be called “Power”), find the “ACPI Suspend Type” parameter and try changing its value to any of the available ones. This will change the power saving configuration and may solve your problem with waking from sleep mode.
- What should I do if my Windows 10 laptop won't wake up or turn on?
There are situations when a computer or laptop does not wake up from sleep mode, the fans start spinning, but there is no Windows 10 image. To exit sleep mode, just press any key on the keyboard. If this does not help, you should press the ESC key, after which the computer should turn on. Perhaps, due to the settings of the operating system itself, the computer cannot wake up from sleep mode.
This article will tell you what to do if your computer does not wake up from sleep mode in Windows 10. In sleep mode, all programs remain turned on, and data about the PC's operation is stored directly in RAM. At the same time, the screen turns off and the hard drives stop, the RAM operates normally.
Your computer is sleeping without permission
If your computer goes to sleep after a short period of inactivity, you risk losing your work in the middle of a task. Problems of this type can cause even more irritation than PC with signs of insomnia. But this is easy to fix.
Make sure your computer is sleeping
When your computer randomly goes into sleep mode, make sure that the machine has entered sleep mode. Sometimes the cause of random hibernation/shutdown is overheating.
If the internal temperature reaches a level above the threshold, your computer will either go into hibernation mode or shut down to protect the hardware components. Check out these apps on how to monitor your PC's temperature
These Laptop Temperature Monitoring Apps Can Save Your Hard Drive
These Laptop Temperature Monitoring Apps Can Save Your Hard Drive Overheating is the leading cause of hardware failure. But high temperatures can also slow down your computer. Use one of these apps to monitor and control the temperature of your computer components. Read more,
Restore default plan
If you just upgraded your PC to Windows 10 or did a major upgrade from Windows 10 1803 to 1809, certain power settings may be corrupted. To resolve this issue, open Settings > System and under Power and Sleep settings, tap More power settings .
From here, select Choose when to turn off your display . Select Restore settings to default for this plan .
If this option is not available or does not work, click Change advanced power settings . In the new window that appears, click Restore default plan . Repeat this step for each individual power plan.
Check your screensaver settings
The screensaver utility allows your computer to enter a sleep state to conserve energy. The display turns off and if you have the settings configured incorrectly, your computer may go into sleep mode at random times.
Head to Settings > Personalization and enter screensaver in the search bar.
In the pop-up window that appears, select Nobody from the Screensaver drop-down menu.
Disable third party themes
Many third-party themes are available in the Microsoft Store. It is possible that the theme may cause your computer to sleep at random times. You can disable the theme and return to the default theme.
Head to Settings > Personalization and click on Themes . Now click on the default Windows 10 theme and restart your computer.
Remove the battery
If all the above methods fail and you are working on a laptop, your battery may be to blame. Turn off the computer and remove the battery. Wait a few minutes and insert it again.
Selecting and configuring a power plan
A power plan is a set of hardware and system settings (such as display brightness, sleep mode, and so on) that control the computer's use of power. We recommend setting the default power plan and resetting its settings to default. Because after a clean installation of the operating system, the computer easily wakes up from sleep mode.
- Go to the power section by running the command Powercfg.cpl in the Win+R .
- In the main plans, select Balanced > Power Plan Settings .
- Now click the button Restore the default settings for the scheme.
If you are using an old hard drive (hard drive), you can try to disable it in the circuit settings. By default, there is a period of inactivity after which the disk is turned off.
Disabling the system's fast startup feature
Fast Startup theoretically helps make your computer start up faster after shutting down properly. It does not affect the reboot mode in any way. It works on a similar principle to Windows 10 hibernation mode.
- Under Power Options, go to What the power buttons do > Change settings that are currently unavailable .
- Now in the shutdown options, uncheck Enable fast startup (recommended) and save the changes.
If necessary, you can turn Fast Launch back on in Windows 10. There are also other ways to enable or disable Fast Launch. After which the quick start function from power settings may disappear. If you disabled fast startup using the command line, turn it on.
What is sleep mode and hibernation
These circuits were designed specifically to save battery power by putting computer devices into a low-power mode.
When you exit, all active applications and documents are kept open. After a certain period of time, the user can work with them without losing important information (for example, after being absent from the workplace). But in Windows 10, problems with setting up such transitions are more common than in versions of a lower rank. Let's consider several ways out of this situation.
Updating the system and video card drivers
Checking for updates
Installing operating system updates works the same way as checking system integrity. They both restore the integrity of system files. If there are major system updates, then use system integrity check tools.
- How to disable sleep mode in windows 10?
Go to Settings > Update & Security > Windows Update . Now wait for the results after clicking the Check for updates .
If no updates are found, you will be told that you have all the latest updates installed. There are other ways to update to the latest version of Windows 10.
To check and restore the integrity of system files, just run the command line with administrator rights. In the window that opens, run the command: sfc /scannow
.
The scanning and recovery process takes some time (depending not only on the power of the computer, but also on the version of the operating system and drive). You can also try other methods to restore Windows 10 system files.
Your computer won't sleep
Sleep mode can save your monitor from burning out and prevent your computer from draining battery power. When your computer doesn't go to sleep, it can lead to general instability, decreased power efficiency, frequent kernel hangs, and crashes.
Check your drivers
Check if your drivers are up to date. The most important ones are chipset drivers, network drivers, audio drivers, and BIOS drivers. It's also a good idea to make sure you're running the latest version of Windows 10.
Check the version number and date of last modification. Download the DriverView utility from Nirsoft. Check the version number, installation date, creation or modification date, and digital signature of the drivers.
Update your drivers : Windows will automatically update your drivers through Windows Update. This is a completely safe and reliable method as Microsoft checks the drivers for your system and updates them if necessary.
You can also update your drivers through Device Manager. Right-click the driver and select Update Driver .
Check the manufacturer's website : Most PCs will include a DVD and a support website that lists all compatible drivers with their version number. Bookmark the site and check periodically for driver updates.
Never download third-party applications that claim to update drivers. Their sources are questionable and can make your system unstable.
Check power requests
Drivers and software installed on your computer can interfere with sleep mode by sending requests for power that keep the system running. To view a log of all power requests in Windows 10, press Win + X and select Command Prompt (Admin) . Enter the following command:
powercfg -requests
This will present a list of active power requests. All categories should theoretically be empty. If not, make a note of what is causing the power request.
In the screenshot, you will see that "Caller_type" with process "synergyc.exe" and type "request" as "SYSTEM" prevents the computer from going to sleep.
To solve this problem you can add an override request for this process
powercfg -requestsoverride ""
For example;
powercfg -requestsoverride PROCESS SYSTEM “synergyc.exe”
Check out the latest Wake events
If your computer wakes up unexpectedly and you want to know which device caused the wakeup event, use the following command
powercfg -lastwake
To see a list of devices that activate the system, enter
powercfg -devicequery wake_armed
In the screenshot, you will see that the Ethernet adapter is causing the computer to wake up randomly.
Open the network adapter driver in Device Manager , right-click the driver and select Properties .
In the Energy Management tab, uncheck Allow this device to wake up the computer . If desired, you can leave this option enabled and check the Allow only the magic packet to wake the computer to prevent everything except Wake-On-Lan packets from your computer.
Run the Power Troubleshooter
Chances are that you may be able to customize and customize your power plan settings for multiple tasks. This can lead to various sleep problems.
The Power Troubleshooter fixes these problems by resetting them and suggests ways to resolve them in the future.
Go to Settings > Update & Security and click Troubleshoot . Scroll down and click Power to launch the power troubleshooter.
After completing the procedure, you can view detailed information about all potential problems and their solutions.
Check the compatibility of connected devices
It may also be that some devices connected to your PC are not compatible with the latest version of Windows 10. Some manufacturers are slow to release updates before they become compatible with the newer version of Windows. It may include printers, scanners, gaming consoles, webcams, and more.
Go to the manufacturer's website and check for compatibility issues. If not, turn off your device and check if the sleep problem persists.
Restart your computer in safe mode
Problems in sleep mode are often caused by hardware and software complications during startup. To check if this is the case, restart your computer in Windows 10 Safe Mode
How to Boot into Safe Mode in Windows 10
How to Boot into Safe Mode in Windows 10 Safe Mode is a built-in troubleshooting feature that allows you to fix problems at the root without the intervention of non-essential applications. You can access Safe Mode in a variety of ways even if Windows 10 no longer boots. Read more and see if he can go to sleep. If possible, you need to perform a clean boot to narrow down the error.
Press Win + S to start Windows search. Enter System Configuration to open the application. Click on the Services tab, check Hide all Microsoft services and select Disable all . This will ensure that only the essential services are running.
In the next step, open Task Manager and disable each application that is configured to run at startup. Close both System Configuration and Task Manager. Restart your computer. If your computer can go to sleep, it means that the problem is caused by an application or process.
