How to set your computer to sleep. Perhaps all these jackdaws will already be standing; all the better. This is so that when you press a key on the keyboard or mouse, the computer wakes up. Changing the HiberFileSizePercent and HibernateEnabled File Entries in the Registry

Windows 10, like previous versions of the system, has several built-in power saving modes. Standby appeared in Windows XP, but in subsequent versions of Windows, Microsoft developers have revised how it works. Since then, Microsoft's OS has 3 standby modes:

• Sleep mode.
• hibernation and its associated function - quick launch.
• Hybrid Sleep.

In this article, we will figure out how these modes differ, how they can be turned on or off.

Does the computer support sleep, hibernation, and hybrid sleep?

First, note that these modes do not work on all devices. Computer components must meet certain requirements, and its manufacturer must provide support for power saving modes in the BIOS. You can check which of the modes your computer supports in the following way:

You will receive a list of features that your device supports. Here standby (S3)- This dream.

Sleep mode in Windows 10

What is hibernation (sleep)

When going to sleep, the system turns off the screen, hard drive, and processor. Only the RAM and a small number of related components remain working. Thanks to this, exiting from sleep mode takes just a couple of seconds and returns Windows with applications to the same state in which the user put the PC to sleep. The downside of this mode is the rather high power consumption compared to turning off the computer. Note that if you disconnect from the network (for example, if the battery runs out), all data on the state of the system and applications will be lost.

How to disable sleep mode when closing the laptop lid

The settings that we discussed above only affect the automatic transition to sleep mode. You have probably noticed that laptops also fall asleep when the lid is closed, and tablets - when the power button is pressed.

How to add or remove the Sleep item in the Start menu

Default button Shutdown on the menu Start displays only shutdown and reboot. If desired, you can add a transition to sleep mode there.

Hibernation in Windows 10

What is hibernation

When this mode is activated, the system overwrites all data from RAM to the hard disk, after which the device turns off. When you turn on the computer, loading takes up to a couple of tens of seconds, depending on the speed of the drive. At this time, data from the disk is written back to RAM, which allows you to fully restore the state of the system and applications. The undoubted advantage of this mode is zero power consumption and the ability to recover data even when the network is turned off. Of the minuses, one can note a long boot and constant write operations to the disk, which is not recommended on SSD drives.

The file plays the most important role in making hibernation work. hiberfil.sys located at the root of the system partition. It is in it that Windows records the state of the system and programs. Its size is usually about 70% amount of RAM.

What is fast startup and how to disable it

In recent versions of Windows, the fast startup feature, closely related to hibernation, is enabled by default. The system saves some important files in hiberfil.sys, which allows you to noticeably speed up the loading of Windows. The disadvantage of this mode is problems with or BIOS, as well as the occurrence of slowdowns and, if you do not restart the PC for a long time.

You can disable fast startup in the following way:

How to enable hibernation in Windows 10

The system will create a file hiberfil.sys and add hibernation related options to power settings. Please note that paragraph hibernation on the menu Shutdown will not be added automatically.

The settings for automatic transition to hibernation, its activation when the lid is closed and adding an item to the shutdown menu are absolutely similar to sleep mode. The only difference is that they will only show up in the Control Panel, not in Settings.

How to turn off hibernation in Windows 10

File hiberfil.sys will be deleted. Function quick start system will also become unavailable. If you want to keep fast startup but disable hibernation, you can reduce the file size hiberfil.sys.

How to reduce the size of the hyberfil.sys file

The hibernation feature will be disabled, but the fast start option will remain. If you want to revert everything back, use the following command: powercfg /h /type full.

Hybrid sleep in Windows 10

This mode is a mixture of sleep and hibernation. The system behaves in the same way as when entering sleep mode, but it creates a backup copy of the data from RAM on the hard disk. After a power outage, Windows will attempt to restore the application and system state.

Hybrid sleep is enabled by default on supported devices. In principle, no settings are provided for it and it simply replaces the sleep mode. All the previously discussed sleep parameters work with him. However, due to some cons, you may want to disable hybrid sleep:

• Intensive load on the hard drive. This is contraindicated on SSD drives.
• Inability to use hibernation when hybrid sleep mode is enabled. To activate the hibernation function, you have to disable hybrid sleep and vice versa.

Sleep and hibernation issues

Sometimes you may experience some problems when using standby modes. Let's analyze the most common of them.

Screen turns off when sleep, hibernate, and display off are not enabled

The problem is probably due to the included screensaver.

Computer turns on or wakes up automatically

Computer won't wake up from sleep

This problem can occur due to a problem with the chipset drivers. Go to the device manufacturer's website, download and install the latest available drivers.

These two modes appeared in Windows 7 and Windows 8 and are intended more for - those devices that have a battery. So what is it and What is the difference between sleep modes and hibernation? Especially when you consider that "hibernation" is translated as "sleep". I think many asked this question, turning off the computer through the Start menu.

Sleeping mode in the computer is intended for a kind of setting "pause" the entire process. The computer remains running and consumes energy (albeit much less than in normal mode), but its screen, cooling system and is turned off, and the minimum voltage is applied to the processor, RAM, wireless modules and other components in this mode. To resume work and exit and sleep mode, just move the mouse or press any button on the keyboard. As a result, you will get the system as it was at the moment when it went to sleep - with all open applications.

hibernation mode It looks the same, but inside it's much more complicated. The computer turns off and is completely de-energized (only power is left for the crystal oscillator to maintain the date / time in the BIOS). At the same time, an exact copy of the PC's RAM is written to the hard disk at the time of shutdown, and when the PC is turned on, this image is restored from the hard disk back to the RAM. In other words, the computer remembers the state of the system before going into hibernation mode, and then restores all the tabs and settings as they were. Does it feel like a dream? Yes. This is where the hard drive comes into play.
This process takes longer than waking up from sleep mode (about 10 seconds versus 1-2 seconds), but in any case much faster than a normal Windows boot (1 minute or more).
In addition, after booting from hibernation mode, you can continue working exactly from the place where it was completed (as in the case of sleep mode), but you don’t have to worry about battery drain.
Therefore, hibernation mode is more suitable for laptops.

If you do not have Hibernation in your laptop shutdown options, you can turn it on with the following command:

1. Run ;
2. Enter powercfg -h on and press Enter;
3. Restart your PC.

To remove the Hiberfil.sys file, type powercfg -h off and restart your PC.

By the way, the Hiberfil.sys file is the file needed for Hibernation and it is located in the root of the system drive. It stores information from RAM.

Conclusion: if you do not want to open all the tabs and programs again the next time you turn on your computer, select the sleep mode. Only it is better to use up to 8 hours. For longer "storage" of data, use the Hibernation mode.

Instead of turning off the computer every time, you can simply put it in sleep mode by clicking the corresponding button. How to activate sleep mode, how to disable it, what problems an ordinary user may encounter when working with it - I will try to provide answers to all these questions to a dear reader in this material.

How to enable sleep mode in Windows 10

To put the computer to sleep, click the start button "Start" and in the menu that appears, right-click the manipulator on the power button in the lower left corner, after which you should select the "Sleep Mode" option from the drop-down menu.

After that, the screen will turn off, but the computer itself will not turn off. To return the system to a working state, press any key on the keyboard or lightly move the mouse.

How to disable sleep mode in Windows 10

To disable sleep mode, we will use, as usual, the new "Options" menu available in the start menu. Another way to open it is the combination "Win + I". In the parameters, select the "System" subsection, and then the "Sleep and power" category.

It is in this sector of the menu that you can flexibly debug the inclusion of sleep mode both when the laptop is powered from the battery and from the mains.

Additional customization options are available just below, in the "Related Settings" section, where we can debug the behavior of the PC when the lid is closed or when the shutdown key is pressed. Read more about this in the next section.

Setting the sleep mode in the control panel

By entering the power options menu using the method described above, or by opening the control panel and selecting the “Power Options” section in it, you will also have the opportunity to disable sleep mode and debug its operation, moreover, more subtly and in detail than it was in the previously described method .

Opposite the power scheme you are currently using, click the "Debug scheme" control. In the window that appears, you can set a timer for activating the sleep state both when powered by battery and, again, from the mains. Moreover, you can turn off the sleep state altogether by selecting the “Never” option from the context menu.

To access detailed sleep mode settings, just use the "Change advanced power settings" item at the bottom of the form. In this category, you can set auxiliary options that allow you to:

• set the sleep mode activation period (if set to 0, sleep will be completely disabled);
• activate or deactivate the hybrid sleep mode (in fact, this is one of the sleep mode options, when memory data is saved to the HDD drive in the event of an unexpected power outage);
• activate recovery mode timers after sleep - as a rule, these parameters do not need to be touched at all, except for those cases in which you have difficulty with arbitrary activation of the PC's power immediately after turning it off (if your computer is like this, then the timers must be disabled ).

Finally, another rather important section worth paying attention to is the Cover and Power Buttons category. Here you can set the default behavior of the PC when closing the lid (meaning the lid of the laptop) and the action of the power key (default is "Sleep").

If necessary, as an addition, you have the right to set the settings for disabling drives in the absence of PC activity (in the Hard Drive category), as well as settings for deactivating the PC or lowering the display brightness (in the Screen category).

Common problems when working with sleep mode

1. So, the sleep mode is turned off, the screen is also turned off, but after a short period of time the display is still deactivated and nothing happens. This is the most common problem for users. Go to the control panel, then the section "Personalization and appearance", subcategory "Change splash screen".

Disable , because that's what you see every time in the situation described above.

2. The computer does not wake up from sleep mode - either a black screen is displayed, or there is simply no reaction to button presses, although the indication itself (if any) shows that sleep mode is enabled. The most likely explanation for this PC behavior is an error in the video card driver installed on a laptop or desktop PC by the operating system itself. To resolve this situation, uninstall all drivers using the Display Driver Uninstaller utility, and then install them again from the official website. Important note: if you have a laptop with integrated Intel graphics, you will most likely have to take the final driver from the laptop manufacturer's resource, suitable for Win 7 or 8 and install it in compatibility mode.

3. The laptop or desktop PC power is immediately activated as a result of going to sleep or turning off the device. This behavior has often been observed by the author on Lenovo products (although it may occur on other brands as well). To resolve the problem, disable wake timers in the auxiliary power settings in the control panel (how to get there - see the second section of the presented article).

That's all the problems that the user often encounters when working with sleep mode. I hope that you will never encounter any of the troubles described above, and if you still need to look for a solution to the situation, then you will succeed easily and naturally, which is what I wish you.

Of course, there are some peculiarities in using sleep mode, which we will now consider, for example, why the "hibernation" command is sometimes not in the shutdown menu, or how to wake the computer from sleep by simply touching any key on the keyboard.

Hibernate Windows 7

A lot of letters come with requests to show and tell how to set it up correctly cnactive mode on a laptop and on a simple computer with installed Windows 7. So let's get started: Start->Control Panel->System and Security->Power Options.

In this dialog box, you must select Power Plan, for example, I have selected Balanced, press Setting up a power plan

Here we can choose:

Turn off the display: you need to set the time when the computer turns off the display when completely idle, for example 15 minutes.
Put the computer to sleep sleep mode: you can choose any time, for example, you set 30 minutes, which means that you are working on a computer, urgently left for other things, and left it on, after 30 minutes your computer or laptop will understand that the owner is gone and go to sleep mode.

When you arrive, all you need to do is swipe the keyboard with your hand or press the computer's Power On button (depending on how you set it up, read on) and your laptop will immediately wake up and you can resume work from the place where you had to leave . For example, I can wake up my laptop from sleep mode by pressing any key on the keyboard and Windows 7 immediately restores work, and on a desktop computer it’s easier to press the system unit’s power button.
When using a laptop, you and I will still have access to the function Action when closed digging cover

if you select Sleep in this parameter, then when you close the lid of your laptop, it will go into sleep mode, and when you open the lid and press any key on the keyboard, it will instantly start.

In the Power window, the function is available Require a password on wakeup, it is needed so that no one can use your computer without you, when someone tries to wake your laptop from sleep mode, he will naturally have to enter a password.

Even in the Power tab, we can configure the parameter Pi button actiontanya computer, so that when you press it, the computer would go into sleep mode or hibernation and completed his work. Choose an option To do nothing and when you press the power button with Windows 7, no action will occur.

By default, the computer wakes up when you turn on the power button, if you want you can set it to wake up on pressing any key on the keyboard or touching the mouse. To exit from hibernation Wind ows 7 using the keyboard or mouse, you need to go to the device manager and double-click the right mouse button on the desired device and go to the properties tab Power Management and check the box Allow this device to wake up your computer.

If this number does not work for you, then your peripheral devices do not support this function, but you can find out for sure by typing in the command line powercfg -devicequery wake_from_any and all devices that can be used to wake up the computer from sleep mode will be displayed.

How is hibernation in Windows 7 different from hibernation and what is hybrid sleep?

• Sleep mode: The computer saves information about your open applications in RAM and enters a low power mode, doing this quite quickly, but if your laptop runs out of battery, the computer will simply turn off and your open applications will simply close without saving your work.
• Hibernation: The computer saves all information about your open applications on the hard drive in the hiberfil.sys file and shuts down completely. The only difference is that during hibernation, the computer does not consume electricity at all, while during sleep mode, energy is still consumed. But in order to enter hibernation mode, as well as exit it, the computer needs much more time than when using sleep mode.
• Hybrid Sleep: combines sleep mode and hibernation, the results of your work in open applications are stored in RAM, but also on the hard drive and the computer goes into low power consumption mode, so that when the battery is completely discharged, the results of your work will not be lost.

The simple answer goes like this: The computer enters sleep mode faster than hibernation, and wakes up from sleep mode faster than from hibernation.

You need to be very careful when using sleep mode with some programs, for example, if you set to process or encode video files for several hours and at that time the computer goes into sleep mode, the process will naturally be interrupted by an error. And when the computer wakes up from sleep mode, you will have to start encoding again, in such cases you need to turn off sleep mode for the duration of such a program completely.

• Conclusion: It is preferable to use the hibernation mode if you leave the computer for a long enough time. If, when using the hibernation mode, the computer is completely turned off, for example, the battery is removed, then there is no risk of losing open and unsaved data, since the computer is completely turned off. Sleep mode does not provide such a guarantee.

In the shutdown menu, sometimes there is no "hibernate?"
Hibernation may not appear in this menu if hybrid sleep is enabled in the power settings. Power Options->Setting up a power plan->Change advanced power settings, in these settings, we can disable the use of hybrid sleep mode, remove the password to wake the computer from sleep, and more.

In order to find out what modes your computer supports, type powercfg /a at the command line
Hibernation and sleep mode may not work in windows 7 if they are disabled in your BIOS, read our articles How to get into the BIOS. They may also not work due to outdated drivers for the video card.

When working at a computer, any user sooner or later needs to take a break. With a short pause, it makes no sense to completely turn off the computer, since the subsequent boot will take a lot of time and, moreover, you will have to re-open all the applications you are using. That's why Windows 7/10 has such a useful feature as "Sleep Mode", or "Sleep" mode. There is also another state similar to "Sleep", called. We will not consider it in this article.

What is sleep mode

The "Sleep" mode, formerly called Standby mode, allows you to put the computer into a low power state, in which some components stop receiving power and turn off, and some continue to consume the energy necessary to store information and quickly wake the computer from "Sleep". All data about the current state of files and applications during the transition to sleep mode is copied to RAM, which retains volatility. Those. when the electricity is turned off, all the information recorded in it will be lost, and you will have to make a “new” start of the computer.

If the power supply is not interrupted, then when the power button is pressed (or the so-called wake-up timers are triggered), the data is quickly read from the RAM and the computer returns to normal operation in a matter of seconds. And most importantly, it goes exactly to the state that was at the time of "falling asleep". All open documents and applications will be displayed on the desktop, and you can continue working without any delay.

Akin to Sleep, the hibernation mode differs in that it does not require power supply, i.e. this is a completely non-volatile state. All data is stored on the hard disk in the hiberfil.sys file, from where it is read when Windows starts. You can read more about hibernation in a separate article.

How to enable and configure Sleep mode in Windows 7/10

You can manually put your computer to sleep using the Start menu. We go into it and select the desired item in the "Shutdown" list.

If suddenly in the list of shutdown options there is no line "Sleep" or "Hibernation", you must perform the following steps. First, open the Control Panel and go to the "Power Options" section.

Then on the left click on the item “Action of the power button”.

There is an option to configure Shutdown Options at the bottom of the page. Put a tick next to the item "Sleep mode" and save the changes.

The corresponding line should appear in the shutdown submenu of the Start menu.

In the "Power button action" section, you can immediately set "Sleep" as the mode that the computer will go into when the power button is pressed. For laptops and tablets, the action of the power button is configured separately for the states "On the network" and "On battery".

The computer can go into sleep mode not only after manual manipulations, but also automatically after a specified period of inactivity. To set the parameters for the transition of the computer to the “Sleep” state, return to the “Power Options” section and click on the link “Setting the power plan” (or “Setting the power plan”) next to the active scheme.

Here, in the drop-down list, select the required time interval for the "Turn off the display" and "Put the computer to sleep" parameters.

After setting, do not forget to click the "Save Changes" button.

Advanced Sleep Mode Settings

In order to fine-tune the sleep mode, as well as immediately eliminate some of the problems that often arise with it, we will set additional parameters for the current power scheme. To do this, click on the link "Change advanced power settings".

In the window that opens, we are only interested in certain items. First, open the first branch with the name of the selected power plan (in our case, “Balanced”) and set the value of the “Require password on wakeup” parameter. If you do not want to constantly enter a password, select "No".

Now expand the "Sleep" item and select the "Allow wake timers" option.

- these are various system events that can wake up the computer from sleep mode without your direct participation. For example, Windows will want to install updates or a task from the Task Scheduler will work. All these events are configured by the user, but he can forget about them and as a result the "sleep" of the computer will be "disturbed". In order not to manually look for such events, simply set the "Allow wake timers" parameter to "Off" and all software timers will be ignored.

The “Sleep” branch also allows you to enable the so-called hybrid sleep mode, but we’ll talk about it separately below.

In principle, the basic setting of the “Sleep” mode has been made, and in most cases there is no need to touch the rest of the parameters. If you wish, you can experiment with other settings, however, in this case it is better to understand the essence of each action performed.

In addition to program events, devices can also wake the computer from sleep. Most often this is a keyboard, mouse, network adapter or USB controller. If you don't want your computer to "wake up" after accidentally pressing a button on the keyboard or because of an inadvertently touched mouse, follow these instructions. Go to Control Panel - Device Manager and open, for example, the "Keyboards" item. Right-click on the line "HID Keyboard" and select "Properties".

In the window that opens, go to the "Power Management" tab. Uncheck the box "Allow this device to wake the computer from standby" and save the changes using the "OK" button.

Do the same with the mouse found under Mice and other pointing devices. We will not focus on other devices that can wake the computer from Sleep. Here everything is done in a similar way.

Hybrid Sleep

This is a kind of combination of normal sleep mode and hibernation. The working session when the computer enters the "Sleep" state is saved not only in RAM, but also on the hard disk. If there are no power failures, the computer uses the RAM data when waking up from sleep, but if the power is turned off, the data is loaded from the hard disk. That is, in any case, you will continue to work from the place where you finished.

You can activate hybrid sleep mode in the advanced power options window. Expand the "Sleep" branch and select the "Allow hybrid sleep" option. Set it to "On" and save the settings.

That's all we wanted to talk about hibernation in Windows 7/10. We hope that the information provided will be useful to you.
