The computer does not enter sleep mode. Why doesn't Windows go to sleep? Check if all drivers are installed and update them

Hibernate mode is a convenient option for users who want to make sure that if they need their computer, they can get it into a fully operational state in a few seconds. A little longer windows exits hibernation mode, but it can also be used if you need to save open files, folders, and applications when the computer's power consumption decreases.

A common error in Windows is the computer waking up spontaneously. When sending the operating system into sleep mode or hibernation state, the user notices that the coolers stop for a couple of seconds, the screen goes blank, and after a while the option to select a profile appears on it and the computer again operates in the same mode. If the computer does not go into sleep mode, there may be several reasons for this, and below we will look at them in more detail.

Incorrect power settings

Setting power settings is a task that laptop users are more likely to face than owners of system units. Not all users know that power settings are adjusted not only special utilities for laptops, but also at the level of the Windows operating system. If wake timers are activated in the settings, they may be causing the problem that the computer does not go into sleep mode.

You can check your Windows power settings as follows:

After changes made The problem with the computer automatically waking up should be resolved if it was caused by this setting. If your PC continues to randomly wake up and wake up from hibernation mode, move on to the next solution.

Waking up the computer due to a connected USB device

A common reason for a computer waking up from sleep mode is a USB device connected to it. In most cases, such devices are the mouse and keyboard, which, when power is lost, try to restore it by sending a request to motherboard, and it wakes up from the received signal and launches the operating system.

To determine which USB device wakes up the system and prevent it from waking the computer from sleep mode, you need to do the following:

Having identified the USB device that is causing the computer to not go into sleep mode, you can move on to fixing the problem by:

After completing the settings described above, you can check whether the error that caused the computer to spontaneously exit sleep mode has been resolved.

BIOS Settings

It was already noted above that it may be necessary to update the BIOS if, due to its incorrect operation, the computer wakes up from sleep mode spontaneously. However, this is not the only option when the BIOS is the culprit of the problem. Most BIOS versions have a "Wake on LAN" option. It is necessary so that the system administrator, who is on the same network as the computer, has the ability to wake it up from sleep mode when necessary. If this option does not work correctly, and it is not required on the computer, it is better to disable it so that the PC does not wake up from sleep mode on its own.

To disable the setting, you need to go into the BIOS (by pressing Del or F2 while the computer starts). Next, you need to find the “Wake on LAN” item and set it to the “Disable” state.

Please note: Depending on BIOS version, the item name may vary. You should look for it in the Power section.

Why doesn't Windows go to sleep?

Hello.

Sometimes it happens that no matter how many times we put the computer into sleep mode, it still does not go into sleep mode: the screen goes dark for 1 second. and immediately windows welcomes us again. It's as if some program or invisible hand is pressing a button...

I agree, of course, that sleep mode is not that important, but why not turn the computer on and off every time you need to step away from it for 15-20 minutes? Therefore, we will try to correct this issue, fortunately, most often there are several reasons...

1. Setting up the power supply scheme

Most likely, like me, you will have several tabs - several power modes. On laptops there are usually two of them: balanced and economy mode. Go to the settings of the mode that is currently selected as your main one.

Just below, under the main settings, there is additional options, which we need to go into.

In the window that opens, we are most interested in the “sleep” tab, and in it there is another small tab “allow wake timers”. If you have it enabled, then you need to disable it, as in the picture below. The fact is that this feature, if enabled, will allow the Windows OS to automatically wake up your computer, which means it may easily not even have time to go into it!

After changing the settings, save them, and then try to put the computer into sleep mode again, if it doesn’t go away, we’ll look into it further...

2. Determining a USB device that does not allow you to go into sleep mode

Very often, the reason for a sudden awakening from sleep mode (less than 1 second) can be devices connected to USB.

Most often, such devices are a mouse and keyboard. There are two ways: first - if you are working on a computer, then try connecting them to the PS/2 connector through a small adapter; second - for those who have a laptop, or those who do not want to bother with an adapter - disable wake-up from USB devices in the task manager. This is what we will consider now.

USB --> PS/2 adapter

How can I find out why I woke up from sleep mode?

Quite simple: to do this, open the control panel and find the administration tab. Let's open it.

Here you need to open the system log; to do this, go to the following address: computer management-->utilities-->event viewer-->windows logs. Next, select the “system” log with the mouse and click open it.

Going to sleep mode and waking up a PC is usually associated with the word "Power" (energy, if translated). This is the word we need to find in the source. The first event you find will be the report we need. Let's open it.

Here you can find out the time of entry and exit from sleep mode, as well as what is important to us - the reason for awakening. IN in this case"USB Root Hub" means some kind of USB device, probably a mouse or keyboard...

How to disable USB wake-up?

If you have not closed the computer management window, then go to the device manager (there is this tab in the left column). You can also access Device Manager through “My Computer”.

Here we are primarily interested in USB controllers. Go to this tab and check all root USB hubs. It is necessary that their power management properties do not include a function for allowing the computer to wake up from sleep mode. Where there are checkmarks, uncheck them!

And one more thing. You also need to check your mouse or keyboard if you have them connected to USB. In my case, I only checked the mouse. In its power properties, you need to uncheck the box and prohibit the device from waking up the PC. The screenshot below shows this checkbox.

After the settings have been made, you can check how the computer began to go into sleep mode. If you haven’t left again, there is one more point that many people forget about...

3. Bios settings

Due to certain BIOS settings, the computer may not go into sleep mode! We are talking here about "Wake on LAN" - an option thanks to which the computer can be awakened by local network. Typically this option is used network administrators to connect to your computer.

To disable it, enter the BIOS settings (F2 or Del, depending on the BIOS version, see the boot screen, the login button is always displayed there). Next, find the “Wake on LAN” item (it may be called slightly differently in different BIOS versions).

If you can’t find it, I’ll give you an easy hint: the Wake item is usually located in the Power section, for example in Bios Award it’s the “Power management setup” tab, and in Ami it’s the “Power” tab.

Switch from Enable to Disable mode. Save the settings and restart the computer.

After all the settings have been made, the computer simply must go into sleep mode! By the way, if you don’t know how to wake it up from sleep mode, just press the power button on the computer and it will quickly wake up.

That's all. If you have anything to add, I would be grateful...

The computer does not go to sleep

Recently I looked at a bug in Windows 10, in which, after rebooting the computer, the time interval for the screen saver was lost, but there are times when the computer does not go into sleep mode and, of course, the screen saver does not work.

In this post I propose three options for solving this problem.

To calculate the process (application) that is preventing the computer from going into sleep mode, you need to:

1) Run the command line with administrator rights: for Windows 10, press the key combination Ctrl+Alt+Del. In the Task Manager, select -> File -> Run a new task;

2) in the Open field: write cmd command-> check the box -> Create a task with administrator rights;

3) on the command line write the following command:

powercfg/requests

In the report that appears, you will see which processes or drivers are preventing your computer from going into sleep mode.

Step No. 2. Set up the power supply scheme.

1) Press the key combination Win+R, in the Open field write the command: control

2) in the Control Panel, select -> Hardware and Sound -> Power Options -> Setting up the power supply scheme ->

Windows won't go to sleep

At some point, Windows 7 stopped going into sleep mode, the screen just went dark, and system unit continued to buzz and all this poop instantly responded to the movement of the mouse.

It’s easy to deal with this scourge; we just need to find out what device or service is preventing our PC from sleeping peacefully.

Open the command line as Administrator:

Powercfg/requests

and get a result like:

C:\windows\system32>powercfg /requests DISPLAY: None. SYSTEM: ... ...

In our case it was like this:

We try to stop the services one by one and go into sleep windows mode 7.

It turned out that the recently installed IvideonServer was our ebola, which did not allow us to go into SLEEP mode.

A little later we’ll figure out what to do with this service, but for now we’ll stop the cameras before going into sleep mode.

Sometimes the mouse interferes with the transition to sleep mode; in its properties you need to specify that the driver does not interfere with the transition.

If you have something in your drivers, you can try to solve the problem using the example below:

Powercfg /requestsoverride DRIVER "Device with support High Definition Audio" SYSTEM

Sleep mode and hibernation windows 7 - Oh, MSBRO!

This article provides answers to some of the most common questions about sleep and hibernation mode in Windows 7 / Windows Vista.

What is the difference between sleep mode, hibernation mode and hybrid sleep mode?

Sleep mode is a low power consumption mode that allows you to quickly resume normal power consumption (usually within a few seconds) upon user demand. Putting your computer into sleep mode is similar to pressing the Pause button on your computer. DVD player- the computer immediately stops all operations and is ready to return to operating mode if necessary.

Hibernation mode is a low-power mode designed primarily for laptops. When entering sleep mode, everything open documents and the settings are saved in memory and the computer goes into a low-power mode, and when it enters hibernation mode, all open documents and programs are saved to the hard drive and then the computer turns off. Of all the power-saving modes used in Windows, hibernation requires the least amount of power. If you do not plan to use the laptop for a long period of time and there is no way to recharge the battery, it is recommended to put the laptop into hibernation mode.

Hybrid sleep mode is a mode that is primarily designed for desktop computers. Hybrid sleep mode combines sleep mode and hibernation mode because all open documents and programs are stored in memory and on the hard drive and the computer is put into a low-power mode. If there is an unexpected power failure, the Windows operating system can easily recover data from the disk. If Hybrid Sleep is enabled, entering Sleep mode automatically puts the computer into Hybrid Sleep mode. On desktop computers, hybrid sleep is usually enabled by default.

Why is there no Sleep or Hibernation command on my computer?

Click the Start button, and then click the arrow next to the Shut down button.

The Sleep or Hibernation command may not appear for the following reasons.

• The video adapter installed on the computer does not support sleep mode. Update your video adapter driver, or find information about your video adapter and the drivers it supports in the documentation that came with your computer. More information See Update Drivers: Recommended Links.
• Some settings are controlled by the administrator. For more information, see the article Why Windows Doesn't Allow You to Change system parameters?
• Sleep and other power-saving modes are disabled in Computer BIOS. To enable sleep mode, restart your computer and enter the BIOS. Typically, when the computer boots, the screen displays the name of a key or key combination to enter the BIOS. Because computer manufacturers use different versions BIOS keyboard shortcuts may vary. For more information, see the documentation that came with your computer or visit the manufacturer's website.
• If you don't see the Hibernation command, Hybrid Sleep may be enabled.

To check if your computer supports hibernation modes, click Start -> type cmd in the search box and press Enter. In the window that opens, run the command:

Powercfg /a

How do I disable automatic sleep or hibernation?

The user can set the wait period before the computer enters sleep or hibernation mode, or completely disable automatic transitions to these modes. Attention! For a battery-powered laptop, delaying sleep or hibernation may result in data loss if the battery is completely drained. To prevent your computer from entering power-saving mode, follow these steps:

2) On the Select a power plan page, click Set up a power plan under the selected plan.

4) On the Advanced Options tab, double-click Sleep, double-click Sleep After, and then do one of the following:

• If you're using a desktop computer, click Option, click the arrow, and then click Never.

7) Click OK and then click Save Changes.

How do I wake up my computer from sleep or hibernation?

On most computers, you must press the power button to continue working. However, not all computers are the same. To return your computer to normal operation, you may need to press any key on the keyboard, click the mouse button, or open the lid of the laptop. For more information, see the documentation that came with your computer or the manufacturer's website.

In addition, some computers support remote wake-up over a network. This capability is called remote wake-up or wake-on-LAN. For more information, see What are Wake on LAN capabilities?

Why doesn't my computer go into sleep or hibernation mode as expected, or why does it spontaneously return to work mode?

• It is possible that the computer is entering operating mode due to some device. The most common devices are USB flash drives and USB mice. Make sure that all devices on your computer are installed latest versions drivers. For more information, see Update Drivers: Recommended Links.

Preventing an external device from waking up from sleep mode

1) Open Device Manager. To do this, click the Start button, select Control Panel, System and Security, and then under System, select Device Manager.‌ Administrator permission is required. When prompted for an administrator password or confirmation, enter the password or provide confirmation.

3) Select the Power Management tab and uncheck Allow this device to wake the computer from standby mode.

4) Click OK.

• There may be a program or scheduled task that wakes your computer from sleep mode. Due to default power settings, scheduled tasks cannot wake the computer from Sleep or Hibernation mode. However, some programs can return the computer to normal operation if these settings have been changed.

Preventing a program from waking up from sleep mode

1) Open the “Power Options” section. To do this, click the Start button, select Control Panel, System and Security, and Power Options.

2) On the Select a power plan page, click Change plan settings to select the plan you want to change.

3) On the Set up power plan page, click Change advanced power settings.

4) On the Advanced Settings tab, expand Sleep Mode and Allow Wake Timers, select Disable for both running the computer on plug-in and running on battery power, and then click OK.

External device starts to work incorrectly after resuming from sleep or hibernation mode.

Try disconnecting the device and connecting again. Also make sure that all devices on your computer have the latest drivers installed. For more information, see Update Drivers: Recommended Links.

Does the laptop battery drain in sleep mode?

Sleep mode requires very little power. If a critical battery level is reached in sleep mode, the Windows operating system automatically puts the laptop into hibernation mode.

Is data protected in sleep mode?

To prevent unauthorized access to your data, you must set a password to unlock your computer when you wake up from sleep mode. For more information, see How do I change how I'm prompted for a password when my computer wakes from sleep mode?

I don’t use hibernation, how can I turn it off so that the hiberfil.sys file is deleted? How to enable hibernation?

IN hidden file hiberfil.sys (root system disk) the copy is reset RAM when going into hibernation.

To turn off hibernation, launch a command prompt with administrator rights and run:

Powercfg /h off

To enable:

Powercfg /h on

*note: to run with administrator rights, you need to right-click and select Run as administrator.

How do I configure hibernation when the batteries are low? How to enable/disable low battery notification?

By default, the low battery notification appears when the battery level reaches 10 percent, and the battery backup notification appears when the battery level reaches 7 percent. When the battery level reaches 5 percent (critical battery level), the laptop enters hibernation mode. If your laptop has an older battery that has less power, the remaining 10 percent (when the low battery alert appears) and 7 percent (when the battery reserve alert appears) may not be enough to save documents and log out. . In this case, you should increase the values ​​of the “Level low battery batteries" and "Battery backup level".

A desktop computer with a source will have similar settings uninterruptible power supply(UPS).

The laptop does not see external hard disk what to do windows 7

First, you need to make sure whether you have this feature enabled at all. To do this, you need to go to the power settings. Open the Control Panel and select “Hardware and Sound”.

In the window that opens, in the item "Power supply" you need to click on the link "Setting sleep mode" .

Now, opposite the point “Put the computer into sleep mode” , you need to select a time if you previously had “never”.

If you had a time delay before, or you just installed it, but it didn’t help, then the problem was not in this, but in the installed and running program, which prevents your computer from falling asleep.

You can find out which program is causing this failure through the command line.

To do this, in Start, in the search bar, enter « Command line» , in the results for the corresponding program, right-click and select "Run as administrator" , or right-click on the start button and select "Command Prompt (Administrator)" .

Different power supply modes can be quite useful, we have already talked about them in. So, thanks to sleep mode, you can save not only energy, but also the time it takes to load the operating system.

But this mode does not always work; sometimes Windows does not want to go into sleep mode, or rather, it goes into it and immediately wakes up. Therefore, in this video we will look at the reasons why the computer does not go into sleep mode or hibernation mode.

1) BIOS setup - in the power settings, the Wake On LAN function can be enabled (wake up from the network card). This setting refers to the built-in network card, if you have a network card via a PCI slot, then here you need to pay attention to the Wake On PCI Card function (wake up from a PCI device).

It’s just that data packets can come from the network that wake up the computer. Although this data must have a certain format, anything can happen.

In general, this function is used system administrators to turn on workstations remotely; if you don’t use this, you can safely turn it off.

2) USB device activity such as a keyboard or mouse.

The keyboard and mouse wake Windows from sleep mode by default. But it happens that they do this all the time, thereby preventing the computer from falling asleep, although no one bothers them. Personally, I have had similar situations.

In this case, you need to prevent these devices from waking Windows from sleep mode. But first, let's find out USB devices is it the case? (Start\Control Panel\Administrative Tools\Event Viewer\ Windows logs\System\Source\Power-Troubleshooter).

Here we can see when the system went into sleep mode, when it woke up and who woke it up. In my case, this is a USB Root Hub, which means it is still a USB device.

Next, go to the device manager (My Computer\RMB\Manage\Device Manager\Keyboard\Properties\Power Management\Uncheck - Allow this device to wake the computer from sleep mode\Try to put it to sleep). If it doesn’t work, you can return the checkbox and try with another device until we find the one you need.

In this situation, you need to wake up the computer by pressing the power button.

3) The computer does not go into sleep mode due to programs.

Therefore, you need to prevent programs from doing this (Start\Control Panel\Power Options\Set up power plan\Change advanced power settings\Sleep\Allow wake timers\Value: Disable).

You can also find out which program, service or driver is preventing Windows from going into sleep mode ( Start \ All Programs \ Accessories \ Command Prompt \ RMB \ Run as Administrator \ powercfg /requests). In response to this command, a message will appear indicating the problem.

IN operating system Windows has various power saving options. One of these modes is called “Sleep” - it allows you to save energy. However, experts note that it is mostly useful for laptops, and not for desktop computers, because in this case, even if it is possible to save electricity, it is only a little. In addition, some users have problems resuming Sleep mode: the computer does not respond to buttons, freezes and requires a reboot.

Today I will tell you how to make sure that your computer or laptop does not go into sleep mode. I will show an example at Windows based 7, although there is no particular difference between Windows 8 (8.1) or Windows XP - this process can be said to be universal.

We go to the control panel. To do this, click on the “Start” button, look for the “Control Panel” item and click on it.

Once in the control panel, we find the “Power Options” item here. It is usually located at the very bottom of the window.

A window with power settings will open. On the left side of it you can see the item “Setting the transition to sleep mode” - click on it.

In front of you you will see the settings of the current power plan. All you need to do is select the “Never” modes and click on the “Save Changes” button.

Actually, that’s all, now the “Sleep” mode will not bother you.

By the way, you can get to the sleep mode settings item a little faster. Press the WIN+R key combination and a window will open. Enter the command there powercfg.cpl and click OK.

In this case, a window with power settings will open - you simply will not need to go to the control panel.

For more fine adjustments power supply, you need to go to the “Sleep mode settings” subsection (highlighted with an arrow in the previous screenshot), and then click “Change advanced power settings”.

A small window will open where you can work with different sleep modes and select the time after which one or another mode will be active.

If you have questions, you can ask them using the comments.
