Windows 10 computer turns on. The computer turns on spontaneously. Turning off wake timers

One of the situations you may encounter Windows user 10 - the computer or laptop turns on itself or wakes up from sleep mode, and this may not happen at the most appropriate time: for example, if the laptop turns on at night and is not connected to the network.

There are two main possible scenarios for what is happening

quick launch

This instruction will discuss the second option: randomly turning on a computer or laptop with Windows 10 or waking up from sleep mode without action on your part.

How to find out why Windows 10 wakes up (comes out of sleep mode)

In order to find out why a computer or laptop wakes up from sleep mode, Event Viewer is useful. Windows 10. In order to open it, in the search on the taskbar, start typing “Event Viewer”, and then launch the found item from the search results.

In the window that opens, in the left panel, select “Windows Logs” - “System”, and then in the right panel, click the “Current log filter” button.

In the filter settings in the “Event Sources” section, specify “Power-Troubleshooter” and apply the filter - only those elements that are interesting to us in the context of spontaneous system startup will remain in the event viewer.

Information about each of these events will, among other things, include an "Exit Source" field indicating the reason that the computer or laptop woke up.

Possible output sources:

USB device

Typically, the reasons why the computer turns on unexpectedly for the user are factors such as the ability of peripheral devices to wake it from sleep mode, as well as automatic maintenance of Windows 10 and work with system updates.

As already noted, computer devices, including network cards, and timers specified in the task scheduler (some of them are created during operation - for example, after automatic downloading of the next updates). Separately turn on your laptop or computer and automatic system. Let's look at disabling this feature for each item.

Prevent devices from waking up your computer

In order to get a list of devices that cause Windows 10 to wake up, you can do the following:

Run command line as an administrator (you can do this from the right-click menu on the Start button). Enter the command powercfg - devicequery wake_armed

You will see a list of devices as they appear in Device Manager.

To disable their ability to wake the system, go to Device Manager, find required device, right-click on it and select “Properties”.

On the “Power Options” tab, disable the “Allow this device to wake the computer from standby” option and apply the settings.

Then repeat the same for the remaining devices (however, you may not want to disable the ability to turn on the computer by pressing keys on the keyboard).

How to disable wake timers

To see if the system any wake timers, you can run the command prompt as administrator and use the command: powercfg - waketimers

As a result of its execution, a list of tasks in the task scheduler will be displayed that can turn on the computer if necessary.

There are two options for disabling wake timers - disable them only for a specific job or completely for all current and subsequent jobs.

To disable the ability to wake up from sleep mode when performing a specific task:

Open the Windows 10 Task Scheduler (can be found through a search in the taskbar). Find the task specified in the powercfg report (the path to it is also indicated there, NT TASK in the path corresponds to the “Task Scheduler Library” section). Go to the properties of this task and on the tab “Conditions”, uncheck “Wake up the computer to perform a task”, and then save the changes.

Pay attention to the second task named Reboot in the powercfg report in the screenshot - this is automatic generated by Windows 10 task after receiving the next updates. Manual shutdown waking up from sleep mode as described may not work for it, but there are ways, see How to disable automatic restart of Windows 10.

If you want to completely disable wake timers, you can do this with with help following steps:

Go to Control Panel - Power Options and open the settings for the current power plan. Click "Edit" Extra options nutrition."
In the Sleep section, turn off wake timers and apply the settings you made.

After this, tasks from the scheduler will not be able to wake the system from sleep.

Disabling Wake Up for Automatic Maintenance 10

By Windows default 10 carries out automatic maintenance of the system daily, and can turn it on for this purpose. If your computer or laptop wakes up at night, this is most likely the problem.

To disable output from sleep in this case:

Go to the control panel and open the "Center" item security and maintenance." Expand the "Maintenance" item and click "Change maintenance settings."
Uncheck "Allow task service Wake up my computer at a scheduled time" and apply the settings.

Perhaps, instead of disabling wake-up for automatic maintenance, it would be more reasonable to change the task startup time (which can be done in the same window), since the function itself is useful and includes automatic defragmentation (for HDD, not performed on SSD), malware checking, updates and other tasks.

I hope that among the points listed in the article there was one that suited your situation, but if not, share it in the comments, maybe we can help.

Computer with installed Windows 10 can begin to live its own life, periodically waking up from sleep mode or turning on on its own. The problem is not that serious, but it does cause some inconvenience, especially if it starts at night.

Determining the cause

To understand why Windows 10 turns itself on, use the Event Viewer tool. You can find it using the built-in “tens” search by asking a query of the same name. To get the information you need, click "Windows Logs" - "System", then select the "Filter current log" button in the right panel.

Set up the filter: specify the value “Power-Troubleshooter” in the “Event Sources” field. As a result of applying the filter, only data that relates to the spontaneous startup of the system will remain in the program window.

In the event information, among other things, the output source will be indicated, which will indicate the reason for awakening. Several options are possible:

Power button – the user will turn on the computer independently.
HID device - the system woke up after interacting with the input device (pressed a button on the keyboard, moved the mouse).
Network adapter - the network card is configured in such a way that it starts to wake up the computer when there are incoming connections.
Timer – Windows woke up from sleep by a scheduled event.
Laptop cover (can be called differently).

At some points there will be no information about the source of exit. This is a normal situation; such records will appear even if there are problems with automatic switching on no laptop or computer.

Most often, the reason for the computer waking up on its own is the action of peripheral devices, but automatic maintenance of Windows 10 along with system updates can also have an impact.

Ban on awakening

To get a list of devices that can wake Windows, launch a command prompt with administrative privileges and run the command “powercfg -devicequery wake_armed”.

The devices will appear as they appear in the Hardware Manager. To prevent them from waking up the system, follow these steps:

Repeat this step for all devices that could turn on the computer on their own. Do not touch only the keyboard, otherwise you will not be able to return the system from sleep mode by pressing the keys.

Disable wake timers

To see if any wake timers are working, launch a command prompt with administrative privileges and run "powercfg -waketimers". As a result of executing the command, a list of tasks from the scheduler that can wake up the system will be displayed.

You can disable timers for a specific task or prevent them from running altogether. To set a ban for a specific task:

If you want to completely disable connection timers, then you need to use another method:

After completing these steps, jobs from the scheduler will not be able to wake the system from sleep.

Disabling wake-up for automatic maintenance

Windows 10 performs automatic system maintenance, and the computer can turn on automatically to perform this operation. To disable waking from sleep mode:

You can not prohibit awakening, but simply set a different time for the task to start. Automatic maintenance – useful feature, so you shouldn’t give it up.

One of the situations that a Windows 10 user may encounter is that a computer or laptop turns on itself or wakes up from sleep mode, and this may not happen at the most appropriate time: for example, if the laptop turns on at night and is not connected to the network.

There are two main possible scenarios for what is happening

The computer or laptop turns on immediately after turning it off (usually the problem is in the chipset drivers and the problem is solved either by installing them or disabling the fast Windows startup 10).
Windows 10 turns on itself at random times, for example, at night: this usually happens if you do not use “Shut Down”, but simply close the laptop, or your computer is configured in such a way that it goes to sleep after a certain amount of idle time, although it can happen after completion of work.

This instruction will discuss the second option: randomly turning on a computer or laptop with Windows 10 or waking up from sleep mode without action on your part.

How to find out why Windows 10 wakes up (comes out of sleep mode)

In order to find out why a computer or laptop wakes up from sleep mode, View is useful. Windows events 10. In order to open it, in the search on the taskbar, start typing “Event Viewer”, and then launch the found item from the search results.

In the window that opens, in the left panel, select “Windows Logs” - “System”, and then in the right panel, click the “Current log filter” button.

Information about each of these events will, among other things, include an "Exit Source" field indicating the reason that the computer or laptop woke up.

Possible output sources:

Power button - when you turn on the computer with the corresponding button.
Input devices HID (may be designated differently, usually contains the abbreviation HID) - reports that the system has woken up from sleep mode after actions with one or another input device (pressed a key, moved the mouse).
Network adapter - indicates that your network card is configured in such a way that it can initiate the awakening of the computer or laptop when there are incoming connections.
Timer - indicates that a scheduled task (in the task scheduler) has woken Windows 10 from sleep, for example, to perform automatic system maintenance or download and install updates.
The laptop lid (its opening) can be indicated in different ways. On my test laptop - "USB Root Hub Device".
No data - there is no information to be found here other than the time of waking up from sleep, and such items are found in events on almost all laptops (i.e. this is a normal situation) and usually the subsequent described actions successfully stop the automatic exit from sleep, despite the presence of events with missing information about the output source.

How to disable automatic wake-up

As already noted, the fact that Windows 10 turns on by itself can be influenced by computer devices, including network cards, and timers set in the task scheduler (and some of them are created during operation - for example, after automatic downloading of the next updates) . Separately, automatic system maintenance can also turn on your laptop or computer. Let's look at disabling this feature for each item.

Prevent devices from waking up your computer

In order to get a list of devices that cause Windows 10 to wake up, you can do the following:

You will see a list of devices as they appear in Device Manager.

To disable their ability to wake the system, go to Device Manager, find the desired device, right-click on it and select “Properties”.

On the “Power Options” tab, disable the “Allow this device to wake the computer from standby” option and apply the settings.

Then repeat the same for the remaining devices (however, you may not want to disable the ability to turn on the computer by pressing keys on the keyboard).

How to disable wake timers

To see if any wake timers are active on the system, you can run Command Prompt as an administrator and use the command: powercfg -waketimers

As a result of its execution, a list of tasks in the task scheduler will be displayed that can turn on the computer if necessary.

There are two options for disabling wake timers - disable them only for a specific job or completely for all current and subsequent jobs.

To disable the ability to wake up from sleep mode when performing a specific task:

Pay attention to the second task named Reboot in the powercfg report in the screenshot - this is a task automatically created by Windows 10 after receiving the next updates. Manually disabling sleep mode as described may not work for him, but there are ways.

If you want to completely disable wake timers, you can do so using the following steps:

After this, tasks from the scheduler will not be able to wake the system from sleep.

Disable Wake for Windows 10 Automatic Maintenance

By default, Windows 10 performs automatic system maintenance daily, and can turn it on for this purpose. If your computer or laptop wakes up at night, this is most likely the problem.

To disable output from sleep in this case:

Additionally: in some cases, disabling “quick startup” may help solve the problem.

I hope that among the points listed in the article there was one that suited your situation, but if not, share it in the comments, maybe we can help.

Even when computer users have a stable operating system and the vast majority additional programs, difficulties may still arise. Such problems can rightfully include spontaneous turning off and turning on of the PC, regardless of the user’s actions. We will talk in detail about this, as well as about ways to eliminate faults of this kind, later in this article.

First of all, it is important to make a reservation that difficulties with automatically turning on the power of a PC or laptop may be associated with mechanical faults. However, diagnosing power failures can be overly complex for a novice user to understand, but we will try to shed enough light on this problem.

If you encounter difficulties not covered in the article, you can use the comment form. We will be happy to help you.

In some, as real-life practice shows, the most common cases, problems with automatic switching on can also come directly from operating system Windows. In particular, this affects users whose computers do not have proper protection against virus programs and are rarely cleared of various OS operating costs.

In addition to all that has been said, we recommend that you study each side instruction without fail, regardless of the actions described. This approach will help you get rid of the problem that appears with the system turning on spontaneously without unnecessary difficulties.

Method 1: BIOS Settings

Quite often, users of fairly modern computers have difficulty turning them on automatically due to incorrectly configured power supply in the BIOS. Here it is important to place special emphasis on the fact that in the vast majority of cases this difficulty arises precisely as a result of incorrect setting of parameters, and not mechanical breakdowns.

Users of old computers equipped with outdated power supply models may not encounter this problem. This is due to radical differences in the process of transmitting electronic impulses from the network to the PC.

If you're using an older AT-powered PC, you can safely skip this block of recommendations and move on to the next method.

If you are the owner modern computer, which has an ATX power supply, then you should do everything exactly according to the instructions, taking into account the unique features of the motherboard.

Try to find out in advance about all the features of the equipment you are using.

Moving directly to the essence of eradicating the problem, you need to pay attention to the fact that literally every motherboard has a unique BIOS. This applies equally to both the number of parameters and limitations in various capabilities.

From the link we provided, check out the methods for getting to the BIOS settings and open it.

The computer BIOS itself may be very different from what is shown in our screenshots as an example. However, be that as it may, you should be guided solely by the names of the menu items mentioned.

In some cases, you may need to go to a special tab "Power", on which all parameters related to power supply are located separately.
Through the presented BIOS menu, go to the section "Power Management Setup", using the appropriate keys on the keyboard for navigation.

Toggle option "Wake Up by Onboard LAN» to mode "Disable" to prevent the PC from starting after receiving certain data from the Internet. This item can be replaced by "Modstrong Ring Resume" or "Wake-On-LAN".

To limit the impact of the keyboard, mouse, and some other types of devices on your PC's power, turn off the "WakeUp by PME# of PCI". This point can be divided into "PowerOn by Mouse" And "PowerOn by Keyboard".

The last rather significant section is the functionality of delayed startup of the computer's power supply, which, by the way, could be activated by malware. To get rid of the problem of spontaneous startup, switch the item "WakeUp by Alarm" in a state "Disable".

The section is interchangeable with items "RTC Alarm Resure" And "Power On by Alarm" depending on the BIOS version on motherboard.

After following the recommendations we have presented, do not forget to check that the computer shutdown system is working properly. Please note that the entire list of actions above is equally suitable for users personal computers and laptops.

The BIOS of laptops works on a slightly different principle due to the different structure and power supply of the device. This is why laptops are often much less susceptible to problems with automatic shutdown or startup.

After you have completed setting the desired settings in your computer's BIOS, save the settings using one of the hot keys. You can find a list of keys on the bottom panel of the BIOS or on the right side.

In case of malfunctions due to making any changes, you can always return the values of all parameters to their original state. Usually the key is reserved for these purposes "F9" on the keyboard or there is a special menu item on a separate tab. Hotkey may vary depending on the BIOS version.

Sometimes updating the BIOS to the latest one or more can help solve problems with the BIOS. stable version. You can find out more details about this in a separate article on our website.

Please note that some settings may revert to the initial state independently due to the influence of virus software.

If after restarting the computer the spontaneous startup stops, this article is considered complete for you. But if there are no positive results, you should resort to other methods.

Method 2: Sleep Mode Problems

At its core, computer sleep mode also relates to this topic, since at this time the system and equipment are in an inactive mode. And although the PC’s input means are turned off during sleep, there are still cases of spontaneous activation.

Don't forget that sometimes hibernation can be used instead of sleep.

Ideally, the state of the computer in sleep mode or hibernation remains unchanged, regardless of any nuances. In this case, the user just needs to press a key on the keyboard or move the mouse to start the awakening process.

Because of this, first of all you need to check the functionality of the connected input devices. This is especially true for the keyboard and possible mechanical sticking of the keys.

In order to resolve all possible difficulties, disable sleep and hibernation mode using the appropriate instructions on our website.

Please note that the sleep itself can be configured differently depending on the version of the operating system used Windows systems.

For example, the tenth version has a unique control panel.

However, some versions of the OS are not very different from other editions of this system.

If it becomes necessary to roll back changes, you can enable sleep or hibernation mode, returning all changed parameters to their original or most acceptable state. To make this type of change easier, as well as for additional methods for enabling sleep mode, please read the appropriate instructions.

On this, in fact, we can finish the analysis of malfunctions that are in one way or another related to the automatic exit of the computer from the sleep and hibernation state. However, remember that the reasons and solutions may be unique for each individual case.

Method 3: Task Scheduler

We touched upon the use of the task scheduler earlier in one of the already mentioned articles, but in the reverse order. Checking for unnecessary tasks is extremely important if you are having difficulty turning on automatically because the timer may have been set by virus software.

Be aware that in some cases the functionality of the task scheduler may be distorted by some special programs. This is especially true for software created for automatic shutdown and turning on other applications by time.

In addition, the reason for everything can be applications with functionality "Alarm", capable of independently waking up the PC and performing certain actions.

In some cases, users do not distinguish between methods for shutting down the PC and, instead of shutting down the work, put the equipment into sleep mode. The main problem The point here is that in a dream the system continues to work and can be launched through the scheduler.

Always use the clause "Shutdown" on the menu "Start", not buttons on the PC case.

Now, having dealt with the side nuances, you can begin to eradicate the problem of automatic startup.

Press the keyboard shortcut "Win+R" to bring up the window "Run". Or click on "Start" right-click by selecting the appropriate context menu item.

To line "Open" enter the command taskschd.msc and click the button "OK".

Using the main navigation menu, navigate to the section "Task Scheduler (Local)".

Expand the child folder "Task Scheduler Library".

In the center of the main work area, take a close look at the existing tasks.

Having found a suspicious task, left-click on it and carefully read detailed description in the window below.

If the actions you set were not intended by you, delete the found task using the item "Delete" on the toolbar of the selected element.

Actions of this nature will require confirmation.

When searching for tasks, be especially careful, since it is the main tool for solving the problem.

In fact, this is where you can finish with the automatic turning on of the PC due to incorrect operation of the task scheduler. However, it is still quite important to make a reservation that in some cases the task may be invisible or cannot be deleted.

Method 4: Removing garbage

The simplest, but often effective method can be the simplest cleaning of the operating system from various debris. For these purposes, you can use special programs.

Don't forget to clean too Windows registry, since its unstable operation can provoke problems with PC power.

In addition to the above, do not forget to manually clean the OS using the appropriate instructions as a basis.

Method 5: Virus infection

Much has already been said about this throughout this article, but the problem of virus infection is still relevant. Precisely malicious software may cause changes to power settings in the system and BIOS.

The process of removing some viruses may require additional knowledge from you, for example, regarding Windows launch in safe mode.

One of the options why the computer turns on by itself is broke power button. This happens rarely, but it does happen. In order to check the power and reset buttons, you should find the necessary ones on the motherboard jumpers. For food - Power SW or PWRSW, and for reboot Reset SW or RSTSW.

They are necessary extract, for example, with a screwdriver and hold short circuit PWR SW contacts. Now the computer turns off, and if it turns back on, then put the buttons back in place. They have nothing to do with it. The power button jumper does not need to be connected.

If the computer does not start working, you can try removing the jumper ResetSW and put it in its place PowerSW. Now you will include your PC with a button reboot. If you don't like it, look for the cause of the short circuit; perhaps the wires are broken somewhere.

Another reason - power unit.

Thanks to it, power is supplied to all components of the computer. Perhaps he is deteriorating, “dying.” Can check this is by finding a fully working unit and connecting it to the computer. If everything is fine, then the problem is in your block.

Software problems

If you installed any programs or games on the day this started, remember them delete. They may be the reasons.

Eat antiviruses who plan to turn on the PC to perform a scan. This can be resolved by going to the folder Windows -Tasks and delete all files there. At the very least, it's worth a try. reinstalling Windows. Maybe they did it viruses, and it will be very difficult to remove such ones.

Incorrect BIOS settings

Perhaps it's a matter of settings BIOS that you managed to change. First you need to enter the BIOS. For this when turning on press the keys F2, Esc, or Del depending on your BIOS version.

So as not to suffer reset settings. This item can be found in the section Exit. If nothing has changed, then move on.

Let's go to Power Management Setup. Next, select Power Management Events, and then Wake-Up by PCI card.
If the value is Enabled, then change it to Disabled.
Now click F10 And Enter.

Check, the problem should be resolved.

Also in BIOS there is a function inclusion scheduled Wake Alarm, Power on by Alarm, RTC Alarm Resume. You just need to put Disabled.

Sometimes you need to turn it on by pressing the keyboard or mouse Power On By Keyboard, Power On By Mouse. It also needs to be turned off.

And the last option Integrated Peripherals– turning on the PC upon power failure and supply. Turn it off too. After all this F10 And Enter.

Now the anomalies with the computer turning on spontaneously will end.
