What does sleep mode mean on a computer? What is the difference between sleep mode, hibernation mode and hybrid sleep mode? How to wake up your computer from sleep or hibernation

In the operating room Windows system There are several computer shutdown modes - this is normal mode (which completely turns off the PC), hibernation mode and sleep mode. The last two shutdown methods are justified when the user wants to interrupt work for a while, but there is no need completely, and wants to immediately return to his work environment, with everyone open source software and documents. What sleep mode is and how it differs from the one discussed earlier will be discussed in this article.

Computer sleep mode. What it is?

Hibernation or sleep mode is a state of a computer that is turned off, in which information about the current state is stored in, applications remain running and wait for operations from the user. The screen goes dark and stops HDD And central processor. There is food left for random access memory and others electronic components, ensuring the system starts from such a state. We can say that the computer is not turned off, but paused, and at the same time consumes very little electricity, compared to full-time work. To “wake up” the computer, simply move the mouse or press a key on the keyboard, after which the user can continue working from where they left off.

What is the difference between sleep mode and hibernation mode?

At first glance, hibernation looks similar to sleep mode and is intended to do the same thing as sleep mode. But the processes that occur when the computer turns off into hibernation are somewhat different. When a user issues a hibernation command, the computer saves the current system state not in RAM, but in . After which the monitor, hard drive and cooling system turn off. Those. hibernation is an even deeper sleep with even lower energy consumption, because... there is no need to apply voltage to the RAM, but only to the internal clock and a minimum of components needed to start the system.

Hibernation mode is more intended for laptops in order to maximize battery conservation in this mode. If for a desktop computer power consumption in sleep mode is not so important, then for a laptop this aspect comes to the fore. The price for such savings is more long start from deep sleep, compared to simple sleep mode. But in any case, the system startup time is much faster than startup after a complete shutdown.

How to put your computer to sleep

Let's look at turning off the computer into sleep mode using Windows 7 as an example, as the most common system at the time of publication of the article.

Most PC users do not know how to disable sleep mode in Windows 7, and sometimes it is necessary to do this, since it is not always convenient for the user.

Initially, sleep mode is a mechanism for reducing power consumption.

At normal operation There is no loss of computer data in this state. If it happened sudden shutdown, data can be recovered from hard drive.

Sleep mode for laptops and PCs

There are several types of such “sleep”:

1. Simple. All files and documents are open on the PC. When entering this state, all initial data is saved in the PC memory, and then the system unit goes into energy-saving operation.
   The process is a bit like pausing while listening to audio or a movie.
2. Hibernation. This “sleep” option is used on laptops, since it is the most economical and uses less battery energy. All information is first saved on the hard drive, after which the computer goes into an energy-saving state.
3. Hybrid type. Enabled by default on desktop PCs with software. All parameters and files are saved on the hard drive before turning on, and the system unit automatically switches to an energy-saving state.
   When the lights are turned off or other power failures, all information is easily restored from drive C.

Disabling sleep mode on a desktop personal computer

How to disable hibernation in Windows 7 (useful things)

Guide: How to disable sleep mode on Windows 7

You can not only change the hibernation settings as described above, but also in a different format.

For correct operation laptops, a system file hiberfil.sys is created on drive C.

Information about Windows 7 RAM is entered into this file when switching to one or another energy saving mode.

If you disable the "sleep state" the standard way, then the file cannot be deleted, which means you will have to do it manually. This will free up several gigabytes of memory on your hard drive.

However, to enter this system file, enter the password to do so account.

IN system files the document looks like the one shown in the illustration below.

How to enter the command line in Windows 7? To do this, go to Start – Run, or type command line through the search.

Of course, there are some peculiarities in using sleep mode, which we will now consider, for example, why there is sometimes no “hibernation” command in the shutdown menu or how to wake up a computer from sleep with a simple touch to any key on the keyboard.

Hibernate Windows 7

A lot of letters come with requests to show and tell how to configure it correctly joint ventureoperating mode on laptop and 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 have selected Power plan, for example, I have selected Balanced, press Setting up a power plan

Here we can choose:

Turn off 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 current mode: you can choose any time, for example, you set it to 30 minutes, this means that you were working on the computer, urgently left for other matters, and it was left on, after 30 minutes your computer or laptop will understand that the owner is not there and will go to sleep mode.

When you arrive, you just need to swipe your hand across the keyboard or press the Power button (depending on how you configure it, 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 operation, but 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 closing digging the lid

if in this parameter Select Sleep, 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 Request password on wakeup function is available; it is needed so that no one can use your computer without you; when someone tries to wake up your laptop from sleep mode, he will naturally have to enter a password.

Also in the Power Options tab, you and I can configure the parameter Action of the pi buttoncomputer tanning, so that when you press it, the computer goes into sleep mode or hibernation, and also completed his work. Select an option Nothing to do and when you press the power button from Windows 7, no action will occur.

By default, the computer wakes up from sleep mode when you turn on the power button, if you want, you can configure it to wake up when you press any key on the keyboard or touch the mouse. To exit from hibernation Wind ows 7 using a keyboard or mouse, you need to go to the device manager and double-right-click on desired device and in properties go to the tab Power management and check the box Allow this device to wake the computer from standby mode.

If this number it won't work for you, it means yours peripherals don't support this function, but you can find out exactly by typing in command line powercfg -devicequery wake_from_any and all devices that can be used to wake the computer from sleep mode will be displayed.

What is the difference between sleep mode in Windows 7 and hibernation and what is hybrid sleep mode?

• Sleep mode: The computer saves information about your open applications in RAM and enters a low power consumption mode, doing this quite quickly, but if your laptop’s battery is completely drained, the computer will simply turn off and your open applications will simply close without saving the work.
• Hibernation: The computer saves all information about your open applications on the hard drive in a file called hiberfil.sys and shuts down completely. The only difference is that during hibernation the computer does not consume any electricity at all, while during sleep mode energy is still consumed. But to enter and exit hibernation mode, the computer needs much more time than when using sleep mode.
• Hybrid sleep mode: 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 when complete discharge batteries, the results of your work will not be lost.

The simple answer is this: The computer enters sleep mode faster than hibernation, and it also exits sleep mode faster than hibernation.

You really need to be careful when using sleep mode with some programs, for example, if you process or encode video files for several hours and at this 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 completely while such a program is running.

• Conclusion: It is preferable to use hibernation mode if you have enough for a long time walk away from the computer. If, when using the hibernation mode, you completely de-energize the computer, for example, remove the battery, 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?" command.
Hibernation may not appear in this menu, with Hybrid Sleep enabled in Power Options. Power->Setting the power plan->Change additional power settings, in these settings, we can prohibit the use of hybrid sleep mode, remove the password for waking the computer from sleep, and more.

To find out what modes your computer supports, type powercfg /a at the command line
Hibernation and sleep mode can doesn't 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 for a reason outdated drivers to the video card.

In the morning and evening, many of us are accustomed to turning on and off the computer. This takes a lot of time. However, we do not turn off mobile phone, when we talk about it, we simply put it into standby mode, turning off the display, and, if necessary, instantly restore its operation with one button. You can do the same with your computer, by refusing to turn it on and off every day.

Instead of turning off the power, you can simply put your computer into sleep or hibernation mode, which will significantly reduce the time it wakes up, which you spend waiting and launching applications every day. When using sleep operating system Saves the system state in memory and enters a low-power mode. Hibernation saves the system state to disk and shuts down the computer completely. Returning the system to working condition at the same time it is done quite quickly. There is also hybrid mode, in which the system state is saved to disk, and the computer goes into a low-power mode.

1. What are the advantages?

No need to wait
At complete shutdown and turning on the computer takes longer than when entering and recovering from sleep/hibernation mode. For example, turning on the computer can take from 1 to 10-15 minutes (depending on the number of programs in startup and the speed of your computer). When restoring your computer from sleep mode, it only takes 5 to 20 seconds!

No need to close working programs
When using sleep/hibernation mode, there is no need to close working programs, because when restored, all your applications will work and be in exactly the same state in which you left them when you switched to sleep/hibernation mode.
At simple shutdown You will need to close all programs and then open them again when you turn them on, which also takes time and effort.

Process automation
When using sleep mode, you can transfer some of the automatic processes to night time. For example, you can use the task scheduler to assign a creation time backups, disk defragmentation and a number of other important operations that take quite a lot of time. Thus, you will not spend a second of your time waiting for the completion of such operations, because they will be performed while you are resting.

This automation is possible if the “Allow wake timers” option is enabled in the power settings. It may also be useful for automatic processes to set a sleep timer. This can be done in the same settings window by specifying the desired value for the “Sleep after” item.

2. How to activate sleep mode and hibernation?

For laptop
In the case of a laptop optimal solution will use sleep mode, which turns on when closing the laptop lid. The laptop is equipped with a battery, and its consumption is very low. Because when frequent use this will be most convenient. At the same time, you will receive almost instant system recovery after opening the laptop lid, which will allow you to immediately get to work.

If you plan to stop working with your laptop for a long time, you can put it in hibernation mode, and then it will not consume energy at all.
If the laptop's battery charge is critical and it is in sleep mode, the system will automatically put it into hibernation mode and completely turn off the power.

Your data will not be affected. After turning on, everything will be restored in the form in which you last left the computer.

To activate sleep mode when closing the laptop lid, go to “Control Panel” - “Power Options” and in the right side panel, select “Actions when closing the lid” and select the desired value.

3. For desktop computer
For a desktop computer that does not have a battery, you can also use sleep mode, but in this case you will have to keep it constantly connected to the network. You can also use hibernation or hybrid mode.

When using hybrid mode, the computer will be restored very quickly, and you will be able to start working almost immediately after pressing the power button (or you can configure the computer to turn on when you press any key on the keyboard or mouse, which is also convenient). In the event of a power outage during hybrid mode, the computer's power will turn off, but data about the system state will remain on the disk and everything will be restored the next time it is turned on.

To activate sleep mode when you press the power button on system unit, go to “Control Panel” - “Power Options” and in the right side panel, select “Actions of the power buttons” and select the desired value.

To activate hybrid sleep mode, open Control Panel - Power Options. Near the active item, click on the “Set up power plan” link. Then select the "Change advanced power settings" link. In the tree window that appears, select “Sleep” and in it the “Allow hybrid sleep mode” item. After saving your changes, Hybrid mode will be automatically activated when sleep mode is activated.

If you do not use a computer or laptop for a while, the display turns off and you get the feeling that the machine is turned off. This situation indicates two situations: either the screen turned off, or the PC went into sleep mode. The given framework is not always suitable, and it is often required change sleep time on Windows 7.

A small digression. All modes are divided into 3 categories:

1. Sleep mode (sleep) is a state of the PC in which there is no shutdown, but reduced power is supplied. All open objects continue to be saved in , allowing you to continue working instantly.
2. . The entire contents of the RAM are flushed to the hard drive, then the power is turned off. Resumption of operation takes much longer, but battery savings increase. This is what distinguishes hibernation from sleep.
3. Hybrid mode – combines the characteristics of sleep and hibernation.

Methods to open the power option

To change the sleep mode transition time in Windows 7, there is an option called “power”, which can be found in 4 ways:

1. Click “start”, enter “power supply” in the search and select the item shown in the picture.

2. Press and copy into the “execute” command input window powercfg.cpl. Click OK or Enter.

3. The most a long way. Go to the start menu, select control panel. Make sure there are large or small icons in the “view” field. On the list Windows settings 7 Find the "power" option.

4. On a laptop, when you click on the button with the triangle icon in the tray, the hidden icons. Among them, find the icon in the shape of a battery and a power plug, click on it with the left button. In the pop-up window, click on any of the 2 links at the bottom.

Changing the Sleep Mode Transition Time

After selecting one of the methods, the power consumption and sleep mode settings window in Windows 7 with adjustable configurations will open in front of you. In the window, click the link to go to sleep mode, it is located on the left.

Here you will be prompted to change the settings of the installed power plan. In my case, this is the “energy saving” plan. It will always be possible to reset the settings to default, so don't be afraid to experiment.

On the laptop you will see 2 columns:

1. On battery
2. From the network

Each column is given individual parameters. On a regular PC, accordingly, there will be 1 column.

To reduce or increase sleep time and turn off the display, click on the button located opposite the corresponding option. Set your time frame and click “save changes”.

If you don't always leave your PC idle for long term, then select "never". This will disable sleep mode on your Windows 7.

To set your own transition time, click the change advanced settings link.

In the window We are interested in 2 sections:

1. Screen

Click on “sleep”, then “sleep after” and set your own time, down to the minute.

Click on “screen”, then on “turn off screen after” and also set the time period.

You can set other parameters, but after making changes, be sure to click the “apply” button and OK.

With such manipulations you can change sleep time in Windows 7. Basically, sleep has practical benefits on laptops or other devices that use a battery. On desktop computer this option practically useless.
