Spontaneous shutdown of a computer running Windows 10. The computer wakes up from sleep mode on its own: causes of the problem and solutions. Disabling automatic wake-up

In Windows 10, as in older versions, a situation often occurs when the computer turns on or wakes up on its own after sleep mode. This drains the device and can lead to various problems. If you want to fix this defect, follow the recommendations below.

How to find out why the laptop turns on Windows 10?

The special Event Viewer feature in Windows 10 allows you to view a detailed log of what is happening with your device. You can open it this way: open Start, start typing: Event Viewer.

Select “Event Log” on the left and go to the System section. Open the “Current Log Filter” function. Under Event Sources, select Power-Troubleshooter. All information will be divided into lines, with information about the reasons why the computer woke up next to it.

Windows 10 by default checks the system for errors weekly. If the computer is turned off at this moment, the OS will activate it, do everything necessary and turn it off again.

Using Control Panel, go to Security and Service Center.

Click Maintenance and open Change Maintenance Settings.

Uncheck the option to wake up your laptop.

Important! If you disable this feature, the check may not occur. It makes more sense to change the scan time to the moment when the computer is running.

Disable wake timers

The task scheduler may contain programs or system applications, which start the computer from sleep mode for various purposes. To find out exactly which timers are active, press WinR and enter the powercfg command. In the window that opens, enter “-waketimers”.

The easiest way is to disable all scheduled timers at the same time; to do this, follow these instructions:

Open Control Panel. Go to the Power Options section and find your current settings.

Click on “Change current power settings”.

Find the section that allows power timers and disable it.

If you want to disable one power setting, use these tips:

Use taskbar search to launch Task Scheduler in Windows 10.

Using the powercfg report, find the timer you need, the path to this timer will be written in the corresponding line.

Go to the Task Scheduler Library, select the appropriate timer and in the personal conditions tab, uncheck the box that wakes up the laptop.

Complete ban on turning on the computer on its own

Run command line on behalf of the administrator.

Enter the command “powercfg -devicequery wake_armed”.

You will see devices that can wake up the system.

Now open Device Manager, find the corresponding device and open its properties by right-clicking. In the power management tab, uncheck the box that allows the device to wake up the laptop.

Important! Please note that the keyboard and mouse are used by the user to wake the computer from sleep mode, so consider whether to disable this feature.

Some users may have encountered a situation where a Windows 10 computer turns on or wakes up from sleep mode on its own. Moreover, this can happen at the most inopportune time, for example, at night.

This can happen in two scenarios. The computer may turn on immediately after being turned off. Chipset drivers may be the cause here. You can solve the problem by installing them or disabling fast launch.

Also, the operating system can be launched at any time. As a rule, this happens because the user does not use “Shutdown”, but closes the laptop, or the computer may fall asleep after a certain period of inactivity. But this can also happen after the work is completed.

Below we will describe the solution to the second problem, when the computer wakes up from sleep mode without user intervention or randomly turns on.

Why does the “ten” wake up

To find out why your computer wakes from sleep mode, you can use Windows 10 Event Viewer. To find this item, you need to type “Event Viewer” in the search, and then launch it. A window will open where you need to select “Windows Logs”, and then click “System”. After this, you need to find and click on the “Filter current journal” button.

Then you need to find the “Event Sources” section and select Power-Troubleshooter in the filter settings, and then apply it. After these actions, only those elements that can influence the independent activation of the system will remain in the window.
The data about each object will contain the “Output Source” field, which will indicate the reason for the spontaneous activation of the device.

Output source options may include “Power button,” when the user turns off the computer independently. “HID Input Device” may also be displayed, which indicates that the operating system woke up after manipulating some input device.

"Network Adapter" reports that LAN card The computer works in such a way that it is able to start the computer when it receives a connection. "Timer" means there is a scheduled task that wakes the system from sleep, or updates need to be downloaded.

If “No data” is indicated, then only information about the time the computer woke up from sleep is displayed. This item can be found on any laptop. All the steps described below can resolve the computer turning on automatically, despite the presence of events without information about the source of the output.

Typically, the reasons for a computer waking up from sleep without the user’s knowledge are the ability of connected devices to turn it on, auto-maintenance of the “tens” and system updates.

How to disable automatic wake-up

As mentioned above, the inclusion of “ten” can be influenced by computer devices, including network cards, timers set in the task scheduler. In addition, the system's auto-maintenance can start the laptop. You need to consider all options for turning on the computer.

Prevent devices from turning on your computer

To view the list of equipment that a computer can include, you need to perform several manipulations. Initially, you need to open the command line as an administrator. After this, you need to enter the command powercfg -devicequery wake_armed into it. A list of devices will appear on the screen.

To disable the ability to wake the system, you need to go to the device manager and find the necessary equipment in it. After this, you need to right-click on it and select “Properties”. In the “Power Options” section, you need to turn off the “Allow this device to wake the computer” option and save the settings. Similar manipulations must be done for all other devices.

How to disable wake timers

To check whether wake timers are working in the system, you need to open the command line as an administrator and enter the command powercfg –waketimers. After it is completed, a list of tasks in the scheduler that can start the computer will appear.

There are two ways to disable wake timers. You can turn them off for a specific job or turn them off completely for your entire computer. In the first case, you need to go to the system scheduler and find the powercfg task in it. Then, in the parameters of this task, in the “Conditions” section, uncheck the “Wake up the computer when the task is completed” checkbox and apply the changes.

In the same report, attention should be paid to the Reboot building. It is created automatically by the system when new updates are received. The manual disabling of spontaneous computer startup described above may not help in this case.

To turn off all computer timers, you need to perform several manipulations. First you need to go to the “Control Panel” and select “Power Options”. Here you need to go to the parameters of the active power supply scheme. Then you need to click on “Change advanced power settings”.

After this, you need to go to the “Sleep” section, where you can turn off all wake-up timers and save the changes. As a result of these manipulations, not a single task from the scheduler will be able to turn on the computer.

Disabling sleep exit for automatic maintenance of “tens”

The latest version of the Windows operating system performs automatic system maintenance every day, and for this you need to turn it on. If the computer wakes up on its own at night, then this is most likely the reason.

To disable this feature, you need to go to Control Panel and select Security and Service Center. Here you need to open “Maintenance” and click on “Change maintenance settings”. After this, you need to uncheck the box “Allow the task to turn on the computer at the scheduled time” and save the changes.

However, in this case, it would be more correct not to disable this function, but to change its execution time, since a lot of work is carried out at this time useful actions, including defragmentation, virus scanning, updating, etc.

No, this article will not talk about settings or programs for automatically turning off the computer.

I will describe a solution to the problem when Windows 10 turns off by itself, and how to prevent it.

First, go to the “Settings” section, then go to “Personalization”, click on “Lock screen” and then “Screen saver options”.

Here we need to make sure that the “Start at login screen” checkbox is unchecked. Then go to “Settings” -> “System” -> “Power and sleep mode”, where we check that all installed options are in the “Never” position. Next, click “ Extra options power supply" and then on "Creating a power management scheme". In the window that opens, check the “High performance” checkbox.
If you did as described above and nothing helped, then another reason (why Windows 10 shuts down) could be due to viruses. Check your computer with an antivirus. Before doing this, be sure to make sure that it is functioning properly.

I would also recommend finding out which applications run with the operating system. You can do this by going to “Taskbars” -> Task Manager, opening the latter through context menu right-click and go to “Startup”, delete unnecessary things.

Moreover, the problem when the computer turns off by itself can be:

• Driver conflict
• Unstable voltage in the electrical network
• Hard drive failure
• Weak power supply or poor contact of the power cord with the power supply
• "Bloated" capacitors
• “Burnt” thermal paste
• Burnt out North Bridge
• Discord between established software. For example, many people manage to install several programs for one action, say, Kaspersky Anti-Virus + Dr.Web + Avast. It is also not uncommon for unupdated applications to be to blame.
  There was a case when an acquaintance, an elderly man, approached me with a request to look at his computer. Programs could not open on it, the computer constantly turned off and froze. Imagine my surprise when his software was from 2009.
• Poorly installed and configured Windows 10 operating system
• Incompatibilities motherboard with processor. Then the computer will turn off approximately every 20-30 minutes
• Poorly installed hardware. In this case, simply unplug it from the connector and reinsert it. More dust.
• Extra items in the USB input. I had experience when small children inserted a 50 kopeck coin into the connector and the computer would turn on for a while and then turn off. And it happened that it didn’t load at all.

Imagine my surprise when his software was from 2009. And why should it work poorly? 10 is shit on its own.

I don’t agree that 10 is bad; if it is bad, it’s only because of its dampness.

Since many users use sleep mode or have just started using it, the problem when the computer wakes up from sleep mode itself can occur to everyone. Lately, I’ve gotten used to not turning off the computer completely, but putting it into sleep mode. Which is a little faster and more convenient. But after a few minutes, or if you were lucky a few hours, the computer would wake up from sleep mode, which was really annoying.

And after a few months, I finally decided to deal with the problem when Windows 10 wakes up from sleep mode on its own. Even though I use it on a computer operating system Windows 10, but this problem is also relevant for users of previous operating systems.

Therefore, in this article we will look at why the computer wakes up from sleep mode on its own and what to do in this situation. Let's look at how to solve the problem when Windows 10 turns on by itself.

First, we need to find out what causes Windows 10 to wake up from sleep mode. For this we use 2 methods, Windows logs and the command line.

First way should be used immediately after the computer wakes up from sleep mode, since the log will store data about this.

After these steps, you will see a list of all computer awakenings. Select by time the point where Windows 10 itself woke up from sleep mode and look at the source of the exit.

Second way allows you to display all devices that can wake up your operating system.

The second method showed that a network card is involved here. We'll look at how to prevent it from waking up from sleep mode next.

The computer wakes up from sleep mode on its own in Windows 10

In the first paragraph of the article, we looked at how to find out why the computer wakes up from sleep mode on its own. Here we will learn how to prohibit exiting sleep mode without your knowledge. First, you need to prevent devices from waking up the computer. To do this, we use the device manager.

After these steps, any device that brought the computer out of standby mode will not be able to do this.

Computer shutdown timer on Windows 10

Perhaps you have set a computer shutdown timer on Windows 10. To check if there are any installed timers, you need to use the command: powercfg -waketimers.

Users of computers, laptops and tablets running Windows 10 periodically encounter automatic wake-up from sleep mode at any time of the day. If you are faced with a similar problem, you will probably be interested in knowing why it occurs and how to solve it. In this article, we have collected all the information about why Windows 10 turns on and wakes up on its own, as well as how you can get rid of it.

Computer hardware components

How to disable wakeup from mouse or keyboard

Quite often, peripherals such as mice or keyboards are to blame for turning on or waking up a device. You may accidentally move the mouse or press a key, after which the computer will start. Here's what you can do about it:

How to disable device wake-up by network card

Many network cards have functionality that allows you to wake the computer from sleep or turn it on. It is worth checking whether such features are activated for you.

Depending on the component model, you may have different options available to you that affect how your computer wakes up.

Sometimes it is also necessary to disable the function Wake-on-LAN in BIOS.

After completing these steps, the network card should not affect the computer turning on.

Operating system software components

In addition to computer components, the device may include some built-in utilities and Windows services 10. The system has special wake-up timers. They are the ones who can launch the device to perform any operations.

To find out what wake timers are set in this moment, do the following:

You can disable specific timers like this:

Even if no timers are currently activated, they may very well appear and wake up your computer in the future. That is why it makes sense to disable them completely.
