Planning to get away from your computer for a while? A dilemma arises. After all, you really don't want to close programs and turn off your computer, and then suffer while waiting for Windows to load! On the other hand, it's a good idea to think about your wallet and reduce your electricity consumption. Many have heard, but not everyone uses the computer's sleep and hibernation modes. Let's consider their differences and draw conclusions about the preference of their use in typical situations.

Users of the most recent editions of Windows (versions 7 and 8) are armed with a combined hybrid sleep mode. Let's take a look at all three options.
Sleep mode
It is characterized by lower power consumption compared to normal computer operation. Some of the computer's components are turned off, for example, the hard drive, and some begin to consume less electricity. All running applications remain in the computer's RAM, continue their work, but are in a standby state. Resuming work from sleep mode occurs almost instantly, you get a ready-to-use computer in a matter of seconds.
Hibernation mode
Designed preferably for use on laptops where battery power and quick use when needed are essential. When hibernation mode is enabled, all running applications from RAM are saved to a separate file on the hard disk of the computer, and the computer itself is turned off. Resuming work is slower than waking up from hibernation, but faster than normal Windows boot. And yes, the system is restored to its original state prior to activating hibernation. That is, all running applications and windows will be restored.
Hybrid sleep mode
It will be useful mainly for desktop systems and unreliable power grids. Combines the benefits of sleep and hibernation. Active applications are saved both in RAM and on the hard drive. The electricity meter is slowing down. The computer will be able to wake up in the correct form even with problems with the power supply. Typically, this mode is already enabled on desktop PCs.
Output
When leaving the computer for a few minutes or for lunch, it is better to use hibernation mode. You will save some of the electricity, and when you return, you can very quickly get to work. Using hibernation mode is important for laptop computers. It is better to use it with long breaks from working with a computer, but, at the same time, wanting to get a workable system in a fairly short time. By using hybrid sleep mode, you can be sure that a depleted laptop battery or a sudden loss of current in the outlet will not result in the loss of unsaved data.
We figured out the concepts. Now the question arises: how to enable these modes?
Hybrid sleep mode is already enabled on the PC. In laptops, you can enable it by opening "Start" and in the search bar enter "Power supply", and then open it. For Windows 8.1, just select Power Management via the right mouse button on the "Start" button.
How are sleep, hibernation, and hybrid sleep different?
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 into sleep mode 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- this is a mode of reduced power consumption, designed primarily for laptops... When you enter hibernation mode, all open documents and settings are saved in memory, and the computer enters a low power mode, and when you enter hibernation mode, all open documents and programs are saved to the hard disk in the hiberfil.sys file, and then the computer shuts down. Hibernation requires the least amount of power to maintain hibernation of all the power saving modes in Windows. If the computer is not going to be used for a long period of time and there is no way to recharge the battery, it is recommended to put the laptop into hibernation mode.
Hybrid sleep mode is a mode that 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. When hybrid sleep is enabled, entering sleep mode automatically puts the computer into hybrid sleep mode. On desktop computers, hybrid sleep is usually enabled by default.
As in normal sleep mode, during hybrid sleep, the computer should not be de-energized. In the event of an unexpected power failure, the Windows operating system can recover data from the disk, but such recovery is not standard and is usually accompanied by an intense load on the hard disk - do not abuse it.
How do I put my computer into one of the modes?
Start---> click on the arrow next to the Shut Down button and select the desired mode:
If Hybrid Sleep is enabled in the power settings, selecting Sleep will place the computer into Hybrid Sleep instead of Normal Sleep.
It is also very easy to choose which of the items will be displayed by default - right-click on the button or on the free part next to it and click "properties". Select the desired option from the Power Button Action menu. The pictures are described.
How to wake up a computer from sleep or hibernation?
On most computers, you must press the power button to resume operation. But since all computers are different, and the way you resume work may be different too. You may need to press any key on the keyboard, press a mouse button, or open the laptop lid to return the computer to normal operation.
Why is there no sleep or hibernate command in the shutdown menu?
- The hibernate command will not display if hybrid sleep is enabled in the advanced power plan settings. If hibernation is required in the shutdown menu, hybrid sleep will have to be disabled.
- The video card does not support sleep mode. Update your graphics card driver.
- These modes are disabled in the computer BIOS. Reboot your computer and enter BIOS (Del or F2 key usually), in power settings enable them. Since the BIOS versions are different on almost all computers, read more about enabling these modes in the instructions for the computer (motherboard) or on the manufacturer's website. To check if your computer supports hibernation, press Start---> in the search box, type cmd and press Enter... In the window that opens, run the command: powercfg / a Some previous BIOS versions do not support the ACPI interface, so computers cannot successfully switch to additional power modes. In this case, you need to update the BIOS of your computer.

A copy of the RAM is dumped into the hidden file hiberfil.sys (at the root of the system disk) when it goes into hibernation.
To turn off hibernation and run:
Powercfg / h off
To turn on:

How do I go into hibernation when the battery is low? How do I turn on / off the low battery notification?
By default, a low battery notification appears when the battery reaches 10 percent, and a backup battery notification appears when the battery reaches 7 percent. When the battery level reading is 5 percent (battery critical level), the laptop enters hibernation mode. If your laptop has an older battery with less power, the remaining 10 percent (when a low battery notification appears) and 7 percent (when a battery backup notification appears) may not be enough to save documents and log out ... In this case, increase the values for "Low battery level" and "Backup battery level".

Sleep, hibernation? Windows 7 is the next generation operating system that has many advanced features. Sleep mode, during which the computer is not in use, can reduce power consumption and reduce the time it takes to wait for a response from the PC when it is resumed. In this article we will tell you what Windows 7 hibernation is, and also take a closer look at each of the options for "lulling" the system.
Computer pending states
- Sleep mode... This function of the operating system allows you to instantly suspend all running processes without closing them. Power consumption is significantly reduced and resumed immediately after the user starts working again at the PC.
- Windows 7 hibernation... Standby mode allows you to pause all running programs and processes, while saving files that were edited on the computer. Electricity is practically not consumed, compared to sleep mode. It is recommended to use this function on laptops. In particular, when the battery charge is low.
- Combined. This PC sleep option is also referred to as hybrid sleep mode. It combines the capabilities of the first two options. When it starts, files and programs are automatically saved, and the system consumes a record low amount of power. Hybrid hibernation is predominantly used on desktop computers. It is activated by default, but you can change it if you want.
Sleep and hibernation. What is the difference?
If many users are familiar with the concept of sleep mode, then the hibernation function appeared not so long ago, and there is little information about it. So, the main differences:
- energy consumption is lower during hibernation;
- the system turns off immediately after backing up data during hibernation, and during hibernation, all processes are simply suspended;
- the system wakes up from sleep mode instantly, and during hibernation, you must wait.
How is the system put into standby mode?
On the computer in the "Start" menu there are already options for transferring the system to modes such as:
- dream;
- hibernation.
The user can independently define the function that will be performed by default. For example, you can set that after a certain time (also set by a person), the system will be transferred to one of these modes.
You can configure the settings by calling the menu in the "Start" by clicking on an empty space next to the modes of operation. Laptops have similar capabilities. In this case, you can set what actions will be carried out when you press the shutdown button. You can bring the computer out of sleep by either opening the lid (of the laptop) or by performing any manipulations on the keyboard or using the mouse.
Summary
Windows 7 hibernation is a universal way to turn off your computer, which requires a minimum of energy consumption and allows you to save all information in the system, which was created or edited at the time of shutdown.
These two modes were introduced in Windows 7 and Windows 8 and are intended more for - those devices that have a battery. So what is it in What is the difference between sleep modes and hibernation? Especially considering that "hibernation" is translated as "sleep". I think many wondered this question, turning off the computer through the Start menu.
Sleeping mode in the computer is intended for a kind of "pause" of the whole process. The computer remains working and consumes energy (though much less than in normal mode), but at the same time its screen, cooling system and, and the minimum voltage is supplied 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 you went to sleep - with all open applications.
Hibernation mode- it looks the same, but inside everything is much more complicated. The computer turns off and is completely de-energized (there is only power to 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 that were. Does it sound like a dream? Yes. Only here the hard drive is involved.
This process takes longer than waking up from sleep mode (about 10 seconds versus 1-2 seconds), but in any case it is much faster than normal Windows boot (1 minute or more).
In addition, after booting from hibernation mode, you can continue to work exactly where it was completed (as in the case of sleep mode), but you do not have to worry about draining the battery.
Therefore, hibernation is more suitable for laptops.
If you do not have Hibernation in the laptop shutdown options, then you can enable it with the following command:
1. Run;
2. Enter powercfg -h on and press Enter;
3. Restart your PC.
To delete the Hiberfil.sys file, you need to 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 disk. It records information from RAM.
Conclusion: if you do not want to reopen all tabs and programs the next time you turn on the computer, select the sleep mode. Only it is better to use it up to 8 hours. For longer "storage" of data, use the Hibernation mode.
We all use a variety of gadgets every day: smartphones, laptops, PCs or tablets. And we also turn them off in different ways. Someone puts you to sleep, someone turns it off completely, and some just close the laptop lid or even leave it on. But which of the modes is better and safer for the device: sleep mode, hibernation, or full shutdown? Today, together with you, we will try to figure it out.
Where are the shutdown options?
First of all, you need to make sure that all shutdown options are available on your PC. To do this, click on the "Shutdown" button directly above the "Start".
If, when using the power button, the system does not offer any of the modes, you should perform the following setup steps:
- We go to "Start".
- We are looking for the "Options" button. It is located above the power button.
- We select the item "System".
- We pass "Power and sleep mode".
- We tap on the line "Additional power options" - "Power button actions".
- We are looking for "Changing the parameters that are now available."
- Tick off "Hibernation mode". In cases where other parameters are not marked, put a checkmark in front of them.
- We confirm our actions by clicking on the "Save changes" button.
What is hibernation?
Sleep mode - pause the process. In this state, the gadget continues to work, consume electricity, but several times less. During "sleep" the tablet or computer turns off the screen, cooling system, hard drive and other drives. At the same time, minimum voltage is applied to the processor, RAM and other components.
You can exit sleep mode and resume work by pressing any key on the keyboard or touch screen. Within a few seconds, you will see the OS as it was left.
How do I use hibernation?
Sleep mode is ideal when the user is away from the workplace for a long time. After setting up sleep mode on your PC, you can go about your business or, when leaving, activate it. And you don't have to worry: when you return, you will start work from the place where you left off.
In case your devices run out of battery and hybrid sleep mode is activated on the computer, the system automatically saves data and then turns off completely.
How do I activate hybrid sleep mode?
Many devices have a function that automatically switches to sleep mode when the battery level is low. Then the computer saves all data on the hard disk and "falls asleep", if the device is connected to the network, it automatically "wakes up". This is Hybrid Sleep.
You can enable the Hybrid Sleep feature by doing several of the following:
- We tap on the "Start" button.
- We go into the parameters (it is located above the power button).
- We select "System" and then the item "Power and sleep mode".
- We are looking for the line "Additional power settings" - "Power scheme settings".
- We select "Change advanced power settings".
- We open the item "Sleep" by clicking on the "+" next.
- Then he clicks the + next to Enable Hybrid Sleep.
- We tap "On" - "Apply" - "Ok".
Hibernation - what is it?
Hibernation is another type of computer shutdown. It might seem like it is very similar to hibernation. But this is only at first glance! During hibernation, the device shuts down completely, writing a copy of RAM to the hard drive or flash drive. And, including the device, all information is restored back to RAM. The wake-up process from hibernation takes about 10 seconds.
This mode is ideal if the user does not know when he will be able to connect the device to the network. It is also ideal for PC users who are concerned about electricity consumption.
When is the best time to shut down your computer completely?
Looking at the examples above, it might seem that the shutdown function is unnecessary. This is not true! The device should always be turned off if you are not going to use it for a long time, as well as during air travel, leaving the device in the luggage compartment.
