Many Windows users, mostly laptop owners, often wonder what is hibernation? This mode is similar to sleep mode, with the difference that it saves all open applications, the clipboard and other user information not in RAM, but in a separate system file and turns off the laptop or computer. Then, when you turn it on again, all the necessary things are loaded from this file. But that is not all. In this article, we will explain in detail what hibernation is on Windows 7.

Ways to disable hibernation

Since many users do not know what Windows 10 hibernation is and how to work with this mode, in this article we will talk about the features of this mode and how to turn it off. How to disable hibernation on Windows 10 - everything is extremely simple: just open the Windows command line and write in it powercfg -h off. After that, windows hibernation will stop working on your computer and you will no longer have to worry about unfamiliar mode. Hibernation in a laptop is turned off in exactly the same way and does not require any additional action.

Since many laptops in a high-quality operating system can use older versions, it is worth noting that in Windows 8 hibernation is disabled in the same way as in Windows 10. We also draw the attention of Windows 7 users that the hibernation mode on their operating system is identical to that on later OS versions from Microsoft.

Proper exit from hibernation

Enabling hibernation is as easy as disabling it. In this case, the hibernation function must be returned through the same computer command line.

An equally common question is how to get out of this mode. To do this, we have compiled a whole instruction, following which you can safely exit the hibernation mode.

1. Try moving the mouse or pressing some keys on the keyboard. As a rule, users simply confuse standby, sleep and hibernation, which may cause some problems. Hibernation in Windows will not turn on by itself, so often after these actions the laptop or computer wakes up from sleep or standby mode.
2. The second way is to select the Ctrl-Alt-Delete key combination or the power off button, which will restart your computer or laptop and also bring it out of hibernation mode.
3. If these items did not help, then you should use the small Reset button. Don't worry about open files, since all your files will be saved in a dump and will be loaded when you turn on the computer.
4. Extreme measures must be taken after the failure of the previous three points and turn off the power from the motherboard. In this situation, you can lose unsaved data, so before using this feature, you should make sure that our previous tips do not help.

Advantages and disadvantages of the regime

What are the advantages and disadvantages of this mode compared to the usual sleep? First, among the advantages, one can note a longer period of battery life due to turning off the laptop. However, this same function is also its disadvantage, since the system file, which stores all necessary information often weighs several gigabytes and can provoke unpredictable conflicts if there is very little space left on your hard drive.

Moreover, unlike sleep mode, the laptop will take much longer to turn on and it may seem that something is wrong with your device. This is due to the fact that the laptop will load all the necessary information from the system file.

When and why to use hibernation mode?

Ordinary users most likely will not need this mode at all, so we recommend disabling it via the command line (as described at the very beginning of this article). For people who often work far from outlets or do not have charger hibernation mode can still come in handy. If you urgently need to postpone work, but keep your progress, then hibernation will come to your rescue. Thanks to it, you will be able to continue your work exactly from the moment you entered hibernation mode.

We hope that our article helped you figure out what hibernation is on a laptop, how it works, how to turn it off or on again, and how to exit this mode. Hibernation is rarely used by ordinary users, so for an unprepared and inexperienced user, it can cause a lot of problems.

All laptops have several shutdown modes: full shutdown, hibernation, and sleep. With shutdown and sleep, everything is more or less clear, but what hibernation is, how it differs from other modes, and how you can configure it, many do not know.

The concept of hibernation

Hibernation is a computer shutdown mode in which data is unloaded from RAM and stored on the hard drive in the hiberfile.sys file. This saving technology allows you to quickly restore the current session after disconnecting the PC from the network.

The hiberfile.sys system file occupies disk space equal to the amount of RAM. This means that no matter what processes are running on the laptop before it goes into hibernation mode, all data will be saved.

To put the laptop into hibernation mode, you need to open the "Start" menu and click on the arrow next to the "Shut down" button. Among the available modes, select the option "Hibernation".

Differences from other modes

To understand how hibernation differs from sleep or full shutdown, and which mode is better to use, let's see what happens to the computer when you select different types completion of work.

• Shutdown - the computer is completely turned off, data from the RAM is unloaded, information about the last session is not saved. If you, for example, printed a document and forgot to save it, then the typed text will disappear.
• Sleep - puts the computer into a low power mode. This means that all components are disabled, except for RAM, which stores information about the current session. If you've been typing a document or watching a movie and then put your laptop or PC to sleep, pick up where you left off when you wake up.
• Hibernation - the computer is completely turned off, but before shutting down, the current session (all running programs) is saved to the hiberfile.sys file on the hard drive. The computer can even be turned off from the network; when turned on, the session will be unloaded from hard drive into RAM, as if the machine were in sleep mode.

If you briefly answer what hibernation is, it is a mixed mode in which there are elements of complete shutdown and sleep. But after hibernation, the computer wakes up longer than after sleep, as the system has to pull data from the hiberfile.sys file and transfer it to RAM.

If you want to leave programs running while saving data, it's better to use hibernation to temporarily shut down your work. This way you can be sure that even if there is a power failure and an emergency shutdown, the changes you make will not be lost.

Enable hibernation

If there is no “Hibernation” button in the “Start”, then you must first enable this feature, and then add a link to it through the control panel. On all versions of Windows, the operation is carried out the same way:

After such a system setup, the corresponding mode will appear in the "Shut down" submenu in the "Start" along with sleep and normal shutdown of the computer. To remove the ability to put the laptop into smart sleep, uncheck the "Actions of the power buttons", and then open the command prompt again and run "powercfg -hibernate off" to disable hibernation.

Laptop shutdown setting

To activate hibernation, it is not necessary to click on the button of the same name in the "Start". If we are talking about temporarily turning off the laptop, then it is better to set up actions when the lid is closed. In this case, lowering the screen to the keyboard, you will quickly put the laptop into hibernation.

Combine different types shutdown depending on how the laptop is running, on mains or on battery. For example, if the laptop is connected to the network, it can be safely sent to sleep, even if the electricity stops flowing, the data will not be lost. If your laptop is running on battery power, put it into hibernation to reduce power consumption and increase battery life.

On laptops, the hiberfil.sys file is responsible not only for saving the current session, but also for quickly starting the system. If you do not hibernate your laptop manually (by pressing a button or closing the lid), but want to maintain a fast startup, then reduce the size of the hiberfil.sys file to free up space on your hard drive.

1. Run command prompt with admin rights.
2. Run the "powercfg /h /type reduced" command.

To revert the hiberfil.sys file to its original size, use the "powercfg /h /type full" command. After completing it, you will be able to manually hibernate the laptop again in order to save the current state of the system with all running applications, while reducing energy consumption.

Many laptop users may have noticed that when turned off, lines such as "Sleep" and "Hibernation" are displayed in the main menu. If everything is clear with sleep mode, then what is hibernation on a laptop? AnyDayLife will answer this and other questions regarding hibernation, sleep and hybrid sleep.

Hibernation was originally developed specifically for laptops, and it is one of the power saving modes. In hibernation mode, the computer consumes much less power than in sleep mode. But this is not the most important difference.

When you close the laptop lid, many models go into sleep mode. Waking up your laptop from sleep mode is very easy and only takes a couple of seconds. Open the lid, press any key and the laptop is ready to work again. All data was written to RAM, which allows you to resume your computer in a matter of seconds.

In the case of hibernation, you will have to wait from 30 seconds to 2 minutes to restore the system (the standard boot time for a laptop of one model or another). During this time, the system switches to normal mode and prepares for operation all the programs and files used during the previous session. You don't have to worry about the safety of your data, because during the transition to hibernation, the data was written to the hard disk in the hiberfil.sys file. The way data is stored is exactly what distinguishes sleep from hibernation.

It is convenient to use hibernation if you have to leave the computer disconnected from the network for a long time. In sleep mode, power consumption is much higher, and since the data is written to the RAM, if there is no network connection, you can lose all unsaved data.

There is also a hybrid sleep mode, but it is mainly designed for desktop PCs. This mode combines both sleep and hibernation: the data is stored on the hard drive, but at the same time, you can restore the system in a matter of seconds.

Now let's figure out how to enable hibernation on a laptop if you need this mode. Firstly, to use hibernation mode on a laptop, there must be much more space on the hard drive than in RAM. If there is not enough hard disk space, hibernation will not be possible. Free up space on your hard drive and restart your computer so that hibernation becomes available again.

Also, hibernation is not possible in cases where the video card does not support this mode. In this case, you will have to update the video card drivers.

Hibernation can be disabled in the BIOS of the computer, and therefore does not appear in the main menu. To enable hibernation before starting the system boot, enter the BIOS (F2 or Del key) and select the power settings menu through which you can enable hibernation.

Since laptops have different BIOS versions, it is better to know initially whether hibernation is supported or not. To do this, in the search bar in the main menu, type cmd and in the window that opens, type the command powercfg / a. The window will list all power saving modes that the BIOS supports and does not support.

You can enable hibernation mode through the command line with administrator rights (cmd). To do this, enter the command powercfg / h on, which will enable hibernation on the laptop. To turn off hibernation, type powercfg /h off.

As you can see, the hibernation mode is quite convenient and you can always use it. But if there is no need for it, then it is enough to turn it off so that the computer automatically goes into sleep mode.

I have hibernation on my laptop. I want to change it to sleep or standby mode. how to do it?

Maslova well you and gee gee

I opened the laptop and there hibernation is loaded. What to do to turn it off and start working

Useful article.

and there is no end to this hypernation. And there is no way to turn on the laptop either. And how it fell on my head. I didn’t turn it on. I’ll have to carry it for repairs.

I bought a new laptop yesterday. In the evening I worked and I closed it. Now write hibernation this day Georgia and I can’t boot. please.

I have an old laptop, 12th year of release ... A weak percentage, but it pulls at work. But I don’t play toys ... Initially (at the 7th factory) hibernation was present, and it suits me in theory - I closed it, opened it and everything is already on) after updating to 8, and then to 10 Windows, hibernation disappeared ... When you enter the power command through the command line, it gives an error 0x65b ... I don’t even know if I need hibernation (there is a sleep mode) or not at all) And what does this error mean? Google doesn't know

When you turn on the laptop, hibernation is enabled. It hung around for a very long time and didn't turn off. I tried removing the battery and putting it back in. When I turned it on again, the laptop turned on without problems.

I opened the laptop, and there the hibernation was frightened, rebooted and now I'm sitting waiting for it to pass, and the Acer computer model

"Hibernation!? What is this?" - this is how most personal computer users react to a newly heard, unfamiliar word.

Within the framework of the article, we will give an answer to this question, and also consider how to configure, enable and disable this mode on your computer.

What is hibernation?

Hibernation (from the English hibernation - “hibernation”) is one of the energy-saving modes of the computer operating system, which allows you to save data from volatile memory (RAM) to non-volatile memory (hard drive) before turning off the power.

What does it give?

Let's imagine a situation when you are working on a solution to a problem and you have opened many applications (including browser tabs), materials, etc. and you need to leave for a few hours.

You can turn off the computer and reopen all documents after turning it on, you can leave the computer on and put it into sleep mode (the computer will be on, but will consume a minimum of electricity).

Or you can use hibernation, in which case the computer will be turned off, but after turning it on you will see all the applications and materials that were open earlier.

Hibernation should not be confused with sleep mode ("Sleep"), because. in contrast, hibernation mode implies a complete power off.

After the power is turned on, the data from the hard disk , are loaded into RAM and the user can resume work directly from the same place where it was interrupted.

Note! There is also a hybrid sleep mode - it is a combination of hibernation and sleep. When using it, the computer is put into sleep mode, at the same time the data from the RAM is uploaded to the hard drive. This measure is necessary in case of a power failure in the event of an unexpected failure.

Enable / disable hibernation mode

As mentioned above, using hibernation uses hard disk space.

The hiberfil.sys file, which is located in the root of the system drive, is usually equal in size to the amount of RAM.

If you do not use the hibernation mode, it makes sense to disable it in order to increase the space on the system disk.

You can turn off hibernation by following these steps:

Reasons for the lack of hibernation mode

In some cases, hibernation may not be available.

To check the availability of this mode, go to the "Start" menu, go to the "Shut down" menu and click the arrow to the right of the menu.

As you can see, the item "Hibernation" is not in this list. This situation may occur when:

Hybrid sleep enabled. To turn it off, go to advanced power settings and turn off hybrid mode.

This mode is disabled in the BIOS of the computer.
To enable it, enter the BIOS and set the appropriate mode. Please note that older BIOSes that do not support ACPI mode cannot work with additional power modes, so to solve this problem, you should update the computer's BIOS.

To check the available hibernation states, you need to launch the command line (an example of how to do this is given above) and write the command:

Setting the hibernation mode

To configure the behavior of the computer in the hibernation state, go to the "Power Options" menu.

To do this, open the Start menu, in the search bar, enter "power" without quotes and go to the appropriate menu.

There are 3 plans available in the power menu:

high performance - the maximum speed of the computer, in exchange for increased power consumption;

energy saving - reduced computer speed, which is achieved by reduced power consumption;

balanced - as the name implies, this plan is a compromise between performance and energy consumption.

The user can configure each plan for his tasks (the "Setting the power plan" item) and use each of them depending on the working conditions simply by moving the checkbox opposite the required plan.

For example, here is the process of setting up a Balanced Power Plan:

The advantages of the mode include the following range of possibilities:

quick completion and start of work;

automatic transition to hibernation mode (depending on the settings of the power plan);

do not answer system questions about saving documents.

The disadvantages of using the hibernation mode include:

the need for additional space on the system hard disk, in an amount equal to the amount of computer RAM;

a number of problems with the withdrawal from hibernation in the case of using certain types of drivers and programs;

the occurrence of problems with exiting sleep mode, in the event of a failure of one of the hardware components of the computer (BIOS, HDD).

security problems because the file containing the copy of the RAM is not encrypted and the data is stored in open form(except OS - OS X).

Hibernation: what is it? Setting, turning on or turning off hibernation

Sleep and hibernation are used by operating systems to conserve power. If you need to get away from your computer for a while, but don't want to waste time turning it off and on, you can put it to sleep. In this state, some of the processes in the Windows OS are disabled, and the PC begins to consume fewer resources. This guide describes hibernation and sleep mode and what they are, how they work and what is the difference between the two modes.

Waiting mode

Sleep, or standby mode (sleep mode) allows you to significantly reduce the amount of power consumption of your personal computer at a time when you are not using it.

During sleep, the PC stops most processes and services, and also turns off the monitors. This allows you to significantly reduce power consumption when the device is idle.

While waiting, the computer, as it were, pauses the operating system, and when the user returns, it starts everything back.

It should be noted that not all PC components support sleep mode. Most often this happens due to the fault of video adapters or drivers for them.

By default, many PCs are set to automatically go to sleep after a certain amount of time of inactivity.

hibernation

Hibernation (translated from English "hibernation" - hibernation) also serves to reduce the power consumption of a personal computer while you are not working with it. However, this process works very differently.

When the PC goes into hibernation, it creates a file on the hard disk in which it saves data on all current processes, running programs, and running services. The contents of RAM are stored in the same file. The file is placed in a special partition on your system hard drive, after which the PC shuts down. Power stops being supplied to all components of the computer, it actually becomes turned off.

However, the next time you turn on the Windows OS, it will not load according to the usual scenario. Instead of simply booting the system from scratch, the computer will use a pre-prepared file so that the user can continue his work right where he left off.

Mode comparison

Hibernation has two big advantages over regular sleep. First, while hibernation is in effect, your personal computer does not consume power at all, which makes this feature more economical.

Secondly, if there is a power outage or a power surge while the device is in sleep mode, all your data may be lost, and PC components may fail. Hibernation allows you to protect yourself from this problem.

Hibernation also has its downsides. Firstly, the exit from it takes much longer than the usual “waking up” of the computer. Secondly, if during preparation for it (when writing the contents of physical memory to a hard disk) a software or hardware failure occurs - your operating system Windows may be damaged.
