Any session of work at the computer, during which several programs can be simultaneously launched and many files open, will end at some point. At the moment of its resumption, it is not very convenient to open all the same windows, but users who know what is hibernation and actively use it, successfully avoiding such inconveniences. How? Everything is simple enough.
Hibernation - what is it
The mode of reduced energy consumption, into which the machine can go automatically or at the command of the operator, is called sleep. Although all previously running processes in the system are stopped, the computer does not completely stop working, it is in standby mode. When Windows hibernation is in progress, all data about the state of the previous session is saved in the device's RAM. Turning on the PC again, the user can start working with all previously opened files and programs in a few seconds. Why is that? Because there is no need to boot a computer from scratch.
If the machine is running Windows 7 or 8, XP or Vista, there is also an option or hybrid. They are different from the sleeper. What is the difference? If the PC is in sleep mode, the data about the state of the previous session is stored in RAM, if it is hibernation, this information is temporarily stored on the hard disk in the hiberfil.sys file. This file is created automatically by the system and is located in the root folder of the partition on which the OS is installed. When using hybrid mode, data is saved both in RAM and on the hard drive.
How to put your PC into hibernation mode
If the user wishes to manually enter Windows sleep mode, he must do the following:
Using the functionality of the system, it can be configured so that the computer will go into a state of reduced energy consumption automatically after a specified period of time. To do this, you just need to know how to configure Windows hibernation through the control panel. Here, too, everything is simple. At the first step, we enter the PU, select “System and Security”.
In the "Power supply" section, we find a link, after clicking on which, we proceed to select a time interval. 
At the next step, everything is intuitively clear how to configure Windows hibernation the way the user wants (after how many hours or minutes the PC should go to “sleep” automatically): select a value from the drop-down list. After completing these actions, save the changes.
You can also configure additional parameters of the mode. For this:
- We select "Power supply" in the control panel;
- Select the power plan you want to configure, click on “settings”;
- We click on the plus sign next to "Sleep", set the required parameters, save the changes.
If "Sleep" is not available
All of these steps are easy if hibernation is enabled by default. Unfortunately, it may turn out differently. Example: there is an item in the menu, but it is not available. Here you need to find out the reasons for the current situation. How to do it? It's simple:
- Right-click on "Start";
- In the search field, enter cmd;
- On the command line, write powercfg / a;
- We press the Enter key.
In the window that appears, read the system message, perform the required actions.
Disconnection
It will not be superfluous to know not only the activation method, but also how to disable Windows hibernation. This is done using the command line:
Now, if the user hovers over the arrow next to "Shutdown", he will not see the item "Sleep". 
How to disable Windows hibernation using the same method using the command line, you can turn it on... To do this, you need to enter powercfg / h on instead of the powercfg / h off command.
As you can see, there is nothing difficult in enabling or disabling Windows hibernation. There is also nothing complicated in setting it up and changing additional parameters. If you have any questions on this topic, you can write about it in the comments below.
But, even extending the life of hard drives, we are faced with a different problem. This is the noise coming from the computer and the high power consumption in the constant on mode. To solve this problem, Windows provides power management modes.
XP is simple: standby and hibernation. The standby mode is very good. We press the button - the hards are turned off, the screen goes out, saving energy and creating silence, but the machine is working and is ready to turn on at any key press on the keyboard or mouse.
In Windows 7, they were too smart: they made three modes. These are, hibernation and hybrid sleep. And the translators have confused everything to the limit. Look, in XP there were and are, as we know, 2 modes: "Sleep mode" was designated as "waiting", and the "Hybernate" mode was translated as "Sleep". Funny translators, in a word.
In Windows 7, "Hybernate" was called "Hibernation" and "Stand by" or "Sleep mode" was designated as "Sleep". And they also created a third mode, which is designated as "Hybrid Sleep".
It is difficult to understand these modes without a glass of Coca-Cola.
?
I had to make the same settings on the installed Windows 7, which correspond to the "Standby" mode in XP. And my adventures began ...
In short, it was experimentally revealed that the "Standby" mode in XP is the "Sleep" mode in Win 7, and the "Hibernation" mode in XP is the "Hibernation" mode in Win 7.
During hibernation, the computer turns off completely, but the contents of the memory are written to a file on hard. When turned on, the session is restored completely, as before the computer was immersed in hibernation. This mode takes a while, which feels a little more than a normal Windows boot.
I will separately say about the hybrid sleep mode in Win 7. It is a combination of sleep mode and hibernation. An image of the memory is taken and saved to the hard disk, as in hibernation. In this case, the computer does not turn off, but goes to reduced power consumption, as in sleep mode.
In Win 7, neither this mixed mode, nor hibernation mode interests me. I need the "Sleep" mode so that I can turn off the screen and hards and turn everything on in a few seconds (analogue of the "Standby" mode in XP). And for this, just, you need to dig deeper into the power settings.
But first, you need to configure the following in the device manager:
Keyboard
Network adapter
Perhaps all these jackdaws will already be standing; all the better. This is so that when you press the keyboard or mouse key, the computer wakes up.
Next, Start -> Control Panel -> instead of "category" select "icons". At the bottom there will be "Power supply", press.
You can customize Sleep by selecting a power plan, such as Balanced. It is better to disable "Sleep" in these settings, and force the computer into this mode at night.
Better to put "Never", about additional power parameters a little lower
You can activate the "Sleep" mode (other modes as well) from the keyboard if it has a Sleep button. Can be activated via the "Start" button. Previously, this mode, like any other, can be assigned to the power button, or you can not assign it, but choose from the drop-down menu:
Power button actions
Assigning modes to the power button and sleep button
You can shut down, or you can choose to sleep or hibernate
And a few more important settings. If we want the "Sleep" mode, but at the same time leave some default settings in the bowels of our "Balanced" energy plan, then the "Sleep" mode simply will not work. This also applies to hibernation.
The default is hybrid sleep mode. We turn it off by going into the additional power settings, as in the screenshot, and turn on, if they are suddenly turned off, the wake-up timers, in order to wake up the computer from the mouse.
Even with all this, there may be problems with the output or input of the computer into the "Sleep" mode. Sometimes the whole computer freezes. Very often, the monitor does not come out of sleep. Here, most likely, the video card is to blame. This is especially noticeable on the Radeon 7000 series.
update the drivers for the video card
update motherboard chipset drivers
turn off the webcam, mouse out of the slots while checking the sleep mode
reset the BIOS by temporarily pulling out the battery and disconnecting the power cord from the socket
They say that the following can still help: change the PCI-E slot of the video card, plug the jumper on the motherboard, update the BIOS, use the monitor, not the TV, change the socket of the video signal output cable to the monitor, play with the wake-up timer modes, disable external card readers and usb -habs, change the default "Aero" theme to another.
7, which allows, after several hours of working on a computer, to pause and then resume the system in its previous form, without closing programs, windows, browsers and other tools we need. Sleep mode is suitable for people who spend a lot of time at the computer and, if necessary, go away for a couple of hours.
It is very convenient due to its simplicity. It can be used both on a laptop and on a stationary computer.
There are 3 ways to enter sleep mode:
- By pressing the start button;
- In the start menu;
- Closing the lid (if you have a laptop);
Believe it or not, to wake up from sleep mode, just press any button on your keyboard, or the power button. As you can see, everything is very simple and anyone can handle it.
How to enable sleep mode
Follow the instructions below to enable sleep mode. Go to "Start -> Control Panel -> System and Security -> Power Supply".
In this window, you must select "Power plan", in our case, the "Balanced" plan is selected. Next to the selected plan, click "Configure Power Plan".
Now you need to select the sleep and display options. I will show you my personal sleep mode settings, but you can adjust them for yourself, for your needs.
Before setting it up, I want to clarify what each of these options means.
- Turn off display: The computer display turns off if it has been inactive for 15 minutes;
- Putting your computer to sleep: A computer that is idle for 30 minutes will be put into sleep mode automatically;
If you have a laptop, then you can use the "Action when closing the lid". This means that when you close the laptop lid, your computer will go into sleep mode, that is, hibernation. And to resume the computer, you just need to lift the lid and press any key.
In the power tab you will also find the function Power button action where you can easily change its purpose. If you are going to enable sleep mode on your computer, I recommend changing the action of the power button to the "Sleep" function.
Below you will also find the option password prompt on wakeup... I do not use it, since my computer is at my house and no one besides me touches it. But if this is your office computer or your computer is used by several users, then I recommend setting a password.
Below I will show you how it differs hibernation in Windows 7 from hibernation mode:
Sleep mode- When the computer enters this mode, your operating system will save all data about open and files in the computer's RAM. After that, the computer switches to low power consumption mode. When you exit sleep mode, you can safely continue working on your computer, from the point of turning it off. (Attention, if you have a laptop and your battery is discharged, then your computer will shut down the computer, thereby losing all data about open programs and files). The system resumes instantly.
Hibernation- When the computer enters this mode, your operating system will save all data about open files and programs on the hard disk. After that, the computer completely shuts down, but the data about open files and programs remains, thus, when the computer exits hibernation, you can continue to work from the last point of its shutdown. It takes about a minute for the system to resume.
I hope this article was useful to you. Good luck.
Most PC users do not know how to disable windows 7 hibernation, and sometimes it is necessary to do this, since it is not always convenient for the user.
Hibernation is originally a low power consumption mechanism.
During normal operation, there is no loss of computer data in this state. If a sudden shutdown occurs, data can be recovered from the hard drive.
Sleep mode for laptops and PCs
There are several types of such "sleep":
- Simple. All files and documents are open on the PC. When you enter this state, all the original data are saved in the PC memory, then the system unit goes into energy-saving operation.
The process is a bit like turning on a pause when listening to audio recordings or a movie. - Hibernation. This type of "sleep" is used on laptops as it is the most economical and consumes less battery power. All information is first saved on the hard disk, after which the computer goes into a power-saving state.
- Hybrid type. Included by default in desktop PCs with software. All parameters and files are saved on the hard disk before turning on, and the system unit automatically goes into an energy-saving state.
When the lights are turned off or other power outages occur, all information is easily recovered from the C drive.
Disable hibernation in a desktop personal computer
If you do not need the hibernation function, and you do not know how to disable hibernation in the Windows 7 settings, then use the following recommendations.
Go to Start - Control Panel.
The settings we need are in the Category section. Go there, then enter the item "Hardware and Sound".
there select the section "Power supply", where you can change the current settings.
However, changing the settings is possible if the user knows the administrator account.
This is where the "Sleep Mode Settings" will be. Click the button.
Something like this will look like the window "Power plan settings" as shown in the picture below. Here you can disable the transition of the computer to hibernation Windows 7.
In order for your computer to be in working order all the time, the settings must be set, as shown in the picture below, that is, the position "Never" on turning off the display and switching to "sleep".
Advice. In order to disable "sleep", go to the plan that is currently active. Next, go to the section "Transfer the computer to sleeping mode", Where you need to select the" Never "function. Then save the settings.
How to turn off Windows hibernation (7, 8.1, 10)
The main function of the sleep mode is to save energy. But sometimes this mode can cause some inconvenience. For example, when watching movies or TV shows over the Internet.
To further disable hibernation, you can enter the advanced settings of Windows 7, and then click the bird next to the item Sleep.
In the Allow Hybrid Sleep settings, click the Disable option.
In order to cancel the function of automatic transition to "sleep", select the function "Never" in the settings.
To do this, enter the number 0 in the minutes state line. Press “Apply” and “OK”.
In the same sequence, where there is a value for "Sleep after", you can disable hibernation in the Windows 7 settings.
How do I disable hibernation on my laptop?
The laptop has a "sleep" function, but different. To change it, it is recommended to do other steps.
As a user, you will need to change the current settings when switching between battery power and utility power.
So, in the similar settings described, you will see two values:
- "On battery"
- "From the network."
To enter the settings, you need to right-click on the computer panel:
The functions "Properties of the taskbar and the Start menu" will appear, then go to "Power supply" - "Setting the plan ..." Balanced ", as shown by the red arrow in the illustration, go to" Change advanced settings ... ".
In the parameters, find "Sleep Hibernation", set the value to "0".

Guide: How to disable hibernation on windows 7
You can not only change the hibernation settings as described above, but also in a different format.
For laptops to work correctly, the system file hiberfil.sys is created on the C drive.
This file records information about the Windows 7 RAM when switching to one or another energy-saving mode.
If you disable the "sleep state" in the standard way, then the file cannot be deleted, which means you have to do it manually. This will free up several gigabytes of hard disk space.
However, to enter this system file, enter your account password.
In system files, the document looks as shown in the illustration below.
How to enter Windows 7 command prompt? To do this, go to Start - Run, or type the command line through the search.
Sleep mode- This is a power saving mode that allows you to quickly resume normal power consumption mode (usually within a few seconds) at the user's request. Putting your computer to sleep is like pressing the Pause button on a DVD player: the computer immediately stops all operations and is ready to resume at any time.
Hibernation mode is a low power mode designed primarily for notebook computers. When you enter hibernation mode, all open documents and settings are saved in memory and the computer enters a low power mode, while when you enter hibernation mode, all open documents and programs are saved to the hard disk and then the computer turns off. Hibernation requires the least amount of power to maintain hibernation of all the power saving modes in Windows. If you do not plan to use your laptop for a long period of time and you cannot recharge the battery, it is recommended that you put the laptop into hibernation mode.
Hybrid sleep mode is a mode designed primarily for desktop computers. Hybrid Sleep Mode combines Sleep and Hibernation because all open documents and programs are saved in memory and on the hard disk and the computer is put into a low power mode. In the event of an unexpected power failure, the Windows operating system can easily recover data from the disk. When hybrid sleep is enabled, entering sleep mode automatically puts the computer into hybrid sleep mode. On desktop computers, Hybrid Hibernation is usually enabled by default
The choice of the mode is up to the user. This article will offer an option to disable "Hibernation", and delete the file hiberfil.sys
How to disable "Hibernation"?
To disable Hibernation, do the following:
You can also turn off the sleep function. Select "" And in the window, find the sleep mode and disable it.
How do I delete the hiberfil.sys file?
After disabling "Hibernation", you can delete the hidden file hiberfil.sys
File hiberfil.sys created by the operating system for hibernation to function. When the computer goes into hibernation mode, Windows flushes the contents of the RAM to the hard disk - to the hiberfil.sys file, and when it is turned on, it loads this file into memory. The file size is equal to the size of the RAM installed on the computer. Thus, by deleting this file, you can significantly add free space on your hard disk. But in Windows 7, even if Hibernate is disabled, the hiberfil.sys file is not deleted and remains on the hard disk. To delete this file, you must have Administrator rights. Click Start - Run, or the Win + R keys, and enter the command
powercfg -hibernate -off or powercfg -h off
We press OK and reboot. If you need to return the hibernation function, you can restore the hiberfil.sys file with the command
powercfg -hibernate -on or powercfg -h on
You can check whether the hiberfil.sys file is in the root of the disk by enabling show hidden files... Start - Control Panel - Folder Options - View
Select "" and uncheck the "" do not forget to press Apply and OK... Open drive C and see that there is no hiberfil.sys file.
To hide the display of protected files, return the items that are marked.
