Most users, over the years of working on a PC (personal computer), have probably never used “standby mode” or “hibernation mode” or other power plans. What is it - let's figure it out.
Sleeping mode"
"Sleep mode" your electronic pet is a special mode that reduces the consumption of electrical energy on a computer or laptop. Let's define not only this mode, but also each of the existing ones.
During computer operation, certain types of files, services, and, in general, all kinds of information are periodically loaded into the RAM. And if you decide to take a little rest during your work and switch your computer to Standby mode- so-called "sleeping mode", then the system does not turn off your computer completely, having completed all work, but only temporarily turns off the power from operating computer components that consume additional electricity (for example, a hard drive (hard drive), video adapter, except RAM (RAM) and, stopping work, goes to "dream".
This mode does not disconnect power from the RAM, because it is, as it were, volatile, and the RAM itself is already loaded with the working system, all the important and necessary programs, as well as services. It turns out that the RAM is simply in its normal state "standby mode". If you forcibly disconnect the power supply from it, then the working information stored in the RAM will be lost without a trace.
Hibernation Mode
Hibernation(from the English hibernation, which means “hibernation”).
In the Russian-language version of the Windows XP operating system, such a function as hibernation is called in the old fashioned way "Sleep mode". Starting with the later Windows Vista, this mode was called "Hibernation". In addition, Windows Vista, as a consequence, introduced an additional detailed function with the wording "hybrid sleep mode", as a result of which the contents of the random access storage device (or RAM for short) are copied to the disk, but the computer’s power supply is not turned off. More on this later.
Hibernation mode. Now, when you tried to put the computer into the above-mentioned hibernation mode, be sure that all, absolutely all the “information” that is crammed into the RAM is now copied to a file located on the hard drive, and as a result the computer turns off completely.
This is the main difference when using Hibernate mode before Sleep mode
, which only partially shuts down your computer. When the computer turns on, all the “information” located in it from the hard drive is rewritten into its RAM, and the entire system is also reversed to its previous state, as if to the starting point before activating the hibernation mode. In addition, this mode is mainly suitable for laptops.
When the laptop is not connected directly to the mains and there is very little battery charge left, it automatically goes into hibernation mode. Subsequently, after connecting it to the network, the previously interrupted user session will definitely be restored, i.e. absolutely no information will ever be lost.
When the shutdown happens completely suddenly, the RAM will be cleared and practically all the documentation, which, unfortunately, you did not manage to save anywhere, will be irretrievably lost.
Hybrid sleep mode
Let's also look at another interesting mode: - "Hybrid sleep". Usually this object combines two types: sleeping mode and almost identical hibernation mode. Combining both modes, its operation is somewhat different from its previous “comrades”, but this is noticeable mainly to confident users. For beginners, the difference is almost imperceptible.
While the “computer” is running, all the necessary information fills the RAM, the contents of which, when switched to activated hybrid sleep mode is copied to a specific file located on the hard drive, and the entire system is plunged into sleeping mode.
Now, if at the moment when your computer is in sleep mode and there is a sudden power outage, which means the memory is cleared, then the information from the hard drive will, accordingly, be automatically transferred to RAM and you can resume work again, but without loss of important and not very important information.
Setting modes
The time has come to determine the settings, as well as where to find them and where to see the location of the modes for their further activation. To do this you need to activate the menu "Start", find the button designation "Shutdown" and activate by pressing the left mouse button ( V
Windows 7
go to additional menu). The mode designations will appear immediately:- "Dream" And "Hibernation". In some cases, only one mode may be indicated - this is "Dream". But essentially it performs the function hybrid sleep mode
.
During the initial installation of the operating system, the wizard determines the location of the OS (operating system), and by default configures, usually, either hybrid sleep mode, if this applies only to a desktop computer, or hibernation mode and sleep mode, if this applies to a laptop.
When setting up these modes, follow the sequence of tasks: - Start
– Control Panel
, then - Power supply
– selection point "Setting up a power plan"
and for this plan we select and denote – Change advanced power settings
, select – Dream
– Enable hybrid sleep mode
.
Depending on versionWindows
The names of the sections may differ slightly, but the essence is the same. Now you need to turn off the hybrid mode in this window and watch the appearance in the menu "Start" two modes - "Dream" And hibernation mode. Allowing hybrid sleeper you end up seeing only the “Sleep” mode and by activating it, you will force your “computer” to go into "Dream", and not in a state hybrid sleep.

When working at a computer, any user sooner or later needs to take a break. During a short pause, it does not make sense to completely turn off the computer, since the subsequent boot will take a lot of time and you will also have to re-open all the applications you are using. That's why Windows 7/10 provides such a useful feature as "Hibernation" or "Sleep" mode. There is also another state similar to "Sleep" called. We will not consider it within the scope of this article.
What is Sleep Mode
The “Sleep” mode, previously called Standby mode, allows you to put the computer into a state of reduced power consumption, in which some components stop receiving power and turn off, while others continue to consume the energy necessary to store information and quickly exit the computer from “Sleep”. All data about the current state of files and applications when entering sleep mode is copied to RAM, which remains volatile. Those. If there is a power outage, all the information recorded in it will be lost, and you will have to start the computer “newly”.
If the power supply is not interrupted, then when you press the power button (or the so-called wake-up timers are triggered), the data is quickly read from RAM and the computer returns to normal operation in a matter of seconds. And what is most important, it goes exactly to the state that was at the moment of “falling asleep.” All open documents and applications will appear on the desktop, and you can continue working without any delays.
The hibernation mode, related to “Sleep,” differs in that it does not require power supply, i.e. This is a completely non-volatile state. All data is saved on the hard drive in the file hiberfil.sys, 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 into Sleep state using the Start menu. We go into it and select the desired item in the “Shut down” list.
If suddenly the list of shutdown options does not include the 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”.
You will be able to configure Shutdown Options at the bottom of the page. Place a checkmark next to “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 enter when you press the power button. For laptops and tablets, the action of the power button is configured separately for the “On Line” and “On Battery” states.
The computer can go into sleep mode not only after manual manipulation, but also automatically after a specified period of inactivity. To set the parameters for the computer to go into the “Sleep” state, go back to the “Power Options” section and click on the link “Setting up a power plan” (or “Setting up a 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 into sleep mode” parameters.
After setting, do not forget to click the “Save changes” button.
Additional 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 supply scheme. To do this, click on the “Change advanced power settings” link.
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 your password, select “No”.
Now expand the “Sleep” item and select the “Allow wake timers” option.
- these are various system events that can wake 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 run. All these events are configured by the user, but he can forget about them and as a result, the computer’s “sleep” will be “disturbed.” To avoid manually searching for such events, simply set the “Allow wake timers” parameter to “Disable” 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 remaining parameters. If you wish, you can experiment with other settings, however, it is better to understand the essence of each action performed.
In addition to software events, devices can wake the computer from sleep mode. 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 accidentally touching the mouse, follow these instructions. Go to Control Panel – Device Manager and expand, for example, the “Keyboards” item. Right-click on the "HID Keyboard" line 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 mode” and save the changes using the “Ok” button.
Do the same with the mouse located in the "Mice and other pointing devices" section. We won’t focus on other devices that can wake a computer from “Sleep.” Here everything is done according to a similar scheme.
Hybrid sleep mode
This is a kind of combination of normal sleep mode and hibernation. When the computer goes into the “Sleep” state, the work session is saved not only in RAM, but also on the hard drive. If there are no power failures, the computer uses the RAM data when waking up from sleep; if the power goes out, the data is loaded from the hard drive. That is, in any case, you will continue working from where you left off.
You can enable hybrid sleep mode in the advanced power options window. Expand the “Sleep” branch and select the “Allow hybrid sleep mode” option. Set it to “On” and save the settings.
That's all we wanted to tell you about Windows 7/10 sleep mode. We hope that the information provided will be useful to you.
But even while extending the life of hard drives, we are faced with another problem. This is noise coming from the computer and high power consumption in constant-on mode. To solve this problem, Windows has power management modes.
In XP everything is simple: standby and hibernation modes. The standby mode is very good. We press the button - the hard drives turn off, the screen goes dark, saving energy and creating silence, but the machine works and is ready to turn on at any key press on the keyboard or mouse.
In Windows 7 they went too far: they made three modes. These are, hibernation mode and hybrid sleep mode. 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 “Sleeping”. Cheerful 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 sleeper”.
Without a glass of Coca-Cola, these modes are difficult to understand.
?
I needed to make the same settings on the installed Windows 7 that correspond to the "Standby" mode in XP. And my adventures began...
In short, it has been experimentally revealed that the "Standby" mode in XP is the "Sleep" mode in Win 7, and the "Sleep" 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 the hard drive. When turned on, the session is restored completely, as before the computer went into hibernation. This mode takes time, which feels a little longer than a normal Windows boot.
Separately, I’ll say about the hybrid sleep mode in Win 7. This is a combination of sleep mode and hibernation. A memory image is made and saved to the hard drive, similar to hibernation. At the same time, the computer does not turn off, but switches to reduced power consumption, as in sleep mode.
In Win 7, I am not interested in this mixed mode or hibernation mode. I need the “Sleep” mode so that I can turn off the screen and hard drives and turn everything back on in a few seconds (analogous to the “Standby” mode in XP). And for this, just, you need to dig a little deeper into the power settings.
But first, you need to configure the following in Device Manager:
Keyboard
Network adapter
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.
Next, Start -> Control Panel -> instead of “category” select “icons”. At the bottom there will be “Energy Supplies”, click on it.
You can set up Sleep mode by choosing a power plan, such as Balanced. It’s better to disable “Sleep” in these settings and force the computer into this mode at night.
It’s better to set “Never”, more about additional power options below
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 select it from the drop-down menu:
What the power buttons do
Assigning modes to the power button and sleep button
You can shut down work, or you can choose sleep or hibernation
And a few more important settings. If we want the “Sleep” mode, but at the same time leave some default settings in the depths of our “Balanced” energy plan, then the “Sleep” mode simply will not work. This also applies to hibernation.
By default, hybrid sleep mode is set. We turn it off by going to the additional power settings, as in the screenshot, and turn on, if suddenly turned off, wake-up timers, in order to wake up the computer from the mouse.
Even with all this, there may be problems with the computer entering or exiting Sleep mode. Sometimes the whole computer freezes. Very often the monitor does not come out of sleep. The video card is most likely to blame here. This is especially noticeable on Radeons of the 7000 series. As an option to solve the glitch with the monitor waking up from sleep, you can try:
update video card drivers
update motherboard chipset drivers
turn off the webcam and mouse from their sockets while checking sleep mode
reset the BIOS by temporarily removing the battery and unplugging the power cord from the outlet
They say that the following can also help: change the PCI-E slot of the video card, change the jumper on the motherboard, update the BIOS, use a monitor and not a TV, change the socket of the video signal output cable to the monitor, play with wake-up timer modes, disable external card readers and usb -hubs, change the standard “Aero” theme to another one.
Sleep mode puts the computer into a power-efficient state and allows you to quickly restore operation. This mode can be turned on either at the user's request or automatically. The latter occurs if no activity is performed on the computer for some time.
After the PC (personal computer) is put into sleep mode, the control system will turn off image output to the monitor and suspend the operation of hard drives and peripheral devices. These actions can reduce energy costs while the computer is not in use by the user or the system.
Options for power saving modes in Windows 7
The following energy saving options are available in Windows 7: sleep mode, hibernation, and mixed mode.
In all of the listed Windows 7 energy saving options, disabling sleep mode is simple and quick by pressing any key on the keyboard.
How to disable sleep mode in Windows 7 - basic methods
Of course, the power saving mode is a convenient thing, but there are cases when removing Windows 7 sleep mode is simply necessary. So, in this mode you will not be able to connect remotely to your computer. And sometimes it’s completely inconvenient to work when your machine “falls asleep” at the first opportunity, especially if it’s not a laptop and you don’t need to save battery power.
Therefore, very often users are faced with a problem: how to disable sleep mode in Windows 7. This dilemma can be solved in the following ways:
- disable hibernation using the control panel;
- using the command line;
- changing the HiberFileSizePercent and HibernateEnabled file entries in the registry.
Let's take a closer look at all of the above methods.
Disable hibernation using Control Panel
Disabling Windows 7 sleep mode by disabling it using the Control Panel is the simplest and most straightforward method that does not require deep knowledge. This option is recommended for new or inexperienced users.
Let's look at disabling hibernation step by step.
Additionally, you can turn it off by selecting "Change advanced power settings." Then we find the “Sleep” item and set the value 0 in the corresponding fields. For the changes to take effect, you must click “Apply” and “OK”.
And what is this amazing hiberfil.sys?
First, let's figure out why a file called hiberfil.sys is needed, and only then we'll look at how to disable sleep mode in Windows 7.
When the computer goes into hibernation, all data about running programs, open documents and other information is saved on the hard drive by writing it to the hiberfil.sys file. After the system wakes up from sleep mode, all data is restored to the computer's memory at the time it went to sleep.
Allows you to save battery power on your laptop. But on desktop computers this mode is rarely used, and hiberfil.sys takes up a significant amount of hard disk space, since its size can be several gigabytes. However, when you disable hibernation, using a file named hiberfil.sys will be automatically created by the system again and again.
How to turn off sleep mode in Windows 7 using the command line
To completely disable hibernation mode, you need to open the cmd.exe console.
- In the Start menu, type cmd.exe in the search box and click search.
- The cmd.exe console opens.
- We launch it with Administrator rights. To do this, move the cursor over cmd and click on the right mouse button. In the menu that opens, you must select run as administrator.
- At the command line, type the command powercfg.exe -h off. After which hiberfil.sys will be deleted automatically.
If you need to re-enable hibernation mode, you need to open it with the command line (repeat steps 1 to 3). In the window that opens, write powercfg.exe -h on to the command line. Then set the required values in the power plan settings.
Changing the HiberFileSizePercent and HibernateEnabled file entries in the registry
Now let's look at how to disable sleep mode in Windows 7 using the registry by changing the HiberFileSizePercent and HibernateEnabled file entries. To do this you need:
- The Registry Editor starts. To do this, press win and R at the same time.
- At the command line, enter regedit.
- Next, you need to navigate to the following registry branch - HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
- We change the parameters of the HiberFileSizePercent file by right-clicking and selecting “Change”, where in the field that opens you should enter the value 0.
- Change the HibernateEnabled file settings in a similar manner.
- You need to close the window and restart your computer.
After all of the above, even a novice user can disable hibernation mode in Windows 7.
“Hibernation mode” is a very useful feature available for use on computers running any version of the Windows operating system. Using it, you can temporarily turn off your PC and quickly wake it up without waiting for a long boot. Let's take a closer look at how to configure sleep mode in the Windows 10 operating system for its proper functioning.
You can put your laptop to sleep using the keyboard. Typically, manufacturers provide a similar function key on one of the buttons F1 - F12, depicting the “Z z” icon on it. It is activated by the key combination Fn + F1 - 12.
To put the computer into a “sleep” state using the software method, just go to the “Start” menu, click on the “Shutdown” button and select “Sleep mode” from the proposed options.
It is likely that this button will not be among the shutdown options. To add it, you need to do the following:
- Click on the search icon located to the right of the Start menu and enter the query “Control Panel”. Go to the first result.
- Select the “Large Icons” view type, go down to the end of the list and go to the “Power Options” section.
- In the window that opens, go to the “Action of the power buttons” item located in the left menu.
- Click on the line “Change settings that are currently unavailable.”
- Activate the “Sleep mode” item in the “Shutdown options” section and click on “Save changes”.
The sleep button will appear among the options to turn off your computer or laptop.
Without leaving the window in which we found ourselves in the last paragraph of the above instructions, you can configure the action of the power button, sleep button and closing the laptop lid to put it to sleep. For laptops, button parameters when operating on battery power and when operating from the network are configured separately.
Let's move on to consider the settings provided by the system in relation to the method we are analyzing to turn off the PC.
The setup can be done according to the following instructions:
- We return to the power settings and click on the “Configure power supply scheme” button opposite the scheme that is currently in use. By default, the scheme used is set to "Balanced".
- In the window that opens, you can configure the computer to automatically go into “Sleep” after a certain amount of time of inactivity. In addition, you can select the time after which only the display will turn off. We set the appropriate parameters for operation on battery and mains power, and then save the changes.
- To go to more detailed settings of the mode, click on the line “Change additional power settings” located in the same window.
- Open the first group of settings, which has the name of the selected power plan. The group contains the “Require password on wakeup” setting, which is responsible for constantly requiring the system to enter a password when the computer wakes up from sleep. If you need to protect your data, it is recommended to set the values to “Yes” in the appropriate items. If there is no need to constantly enter a password, you can select “No”.
- Having completed the setup, go to the “Sleep” group of parameters. Open the “Sleep After” tab, where you can select the time interval for the PC to automatically go into “sleep”.
- The last important change will be setting up wake timers. To gain access to them, you must expand the corresponding item. Wake timers are certain system operations and events that can “wake up” a computer from “sleep” without the direct participation of the user. Such events include the installation of a system update or the time for executing a task from the Scheduler. You can enable all wakeup timers, leave only important ones, or disable them completely to prevent unexpected PC awakenings.
Confirm any changes by pressing the “Apply” and “OK” buttons.
At this point, the basic configuration of parameters can be considered complete. Let's move on to consider a fairly common problem in which the computer can spontaneously “wake up” even when wake-up timers are disabled.
Problems with spontaneous awakening
System events are not the only reason why a computer may wake up from sleep mode on its own. Another reason for such an awakening may be the activity of devices connected to the PC - most often, problems can be created by the keyboard, mouse, network adapter or USB controller.
To prevent your computer from waking up due to an accidentally pressed button on the keyboard or an accidental mouse movement, you must perform the sequence of actions described below:
- Right-click on the “Start” menu and select “Device Manager” (you can also access it through the Control Panel).
- For example, let's look at fixing a problem with a mouse. Expand the “Mice and other pointing devices” branch, then select the “HID-compatible mouse” option, right-click on it and select “Properties”.
- Go to the “Power Management” tab and deactivate the “Allow this device to wake the computer from standby” option. Click on “OK”.
We repeat the above steps with the keyboard and other devices. The scheme of action is absolutely the same in all cases.
Let's take a look at one last useful add-on.
Hybrid sleep mode
Hybrid sleep mode is a great combination of sleep mode and hibernation mode. It allows you to completely secure information in the event of power failures that lead to the deletion of data from RAM - the system will take them from the hard drive, which is not affected by a power outage.
To activate this form of “sleep”, you need to return to the power plan settings, open the “Sleep” group and in the “Allow hybrid sleep mode” section set the value to “On”.
At this point, the analysis of the sleep mode parameters can be considered complete. Let's move on to summing up.
conclusions
“Sleep mode” is a special operating scheme that saves energy, but at the same time maintains the operation of PC components in a gentle mode. In addition, “waking up” the computer from “sleep” occurs much faster than normal startup, which allows the user to immediately begin solving planned tasks.
Video instruction
We attach detailed video instructions in which all the above steps are carried out and explained sequentially.
