Hibernate what's in the computer. Standby Windows modes. Which is better: turn off or put to sleep
When your Windows 10 PC is not in use, it will remain in one of three states until you need it again: Sleep, Hibernate, or Off.
Which one should you choose for your PC? Let's take a look at what each option does, why you might want to use it, and when is the best time to use it.
How to configure the power button settings
The first thing you should do to ensure that all power options are available to you is to examine your PC's power button; it is located directly above the Start button.
You may notice that, for example, there is no hibernation mode when you press the power button. Here's how to configure the options that you access when you press the power button.
What is hibernation
Sleep mode - this is what most computers use when they are not used for a certain period of time. All open windows and their current state are saved in your computer's RAM, so when you open the laptop lid or move your desktop mouse, everything is restored as if you never left. The time it takes to "bring everything back to life" only takes a second or two.
When to use hibernation
Hibernation Mode - great option for laptop and tablet userswho don't know where the next outlet will be. It's also a good option for desktop users who are concerned about power consumption - hibernation does not consume much power.
So why not just turn off your computer? First, starting from hibernation will take less time than booting from scratch. Secondly, whatever you have open on your computer - for example, an important project with multiple windows - will be there as if you never left your workplace.
When to shut down your computer
While other power options will work most of the time, you will still need to from time to time.
- Consider shutting down if you rarely use your computer. For example, if you use it for a few hours on Monday and don't plan to use it until Friday, turning it off would be beneficial.
- Always shut down your computer before disconnecting power. Turning off the power includes things like disconnecting from the wall outlet or removing the battery.
- Always turn off your computer before leaving it for long periods of time, such as when on vacation.
- Always turn off your computer if you plan to mail your laptop or tablet or when you put it in the luggage compartment while traveling by plane or bus.
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 the computer from sleep by simply touching any key on the keyboard.
Windows 7 hibernation
A lot of letters come with requests to show and tell how to set up correctly cnbox mode on a laptop and on a simple computer with installed Windows 7... So let's get started: Start-\u003e Control Panel-\u003e System and Security-\u003e Power.
In this dialog box, you must have selected Power plan, for example, I have chosen Balanced, press Setting up a power plan
Here we can choose:
Disable 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 sleepmode: you can choose any time, for example, you set 30 minutes, which means that you are working on a computer, urgently left for other business, and left it on, after 30 minutes your computer or laptop will understand that the owner is not there and go to sleep mode.
When you arrive, you just need to swipe the keyboard with your hand or press the computer's Power On button (depending on how you set it up, 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 restores work immediately, and on a stationary computer it is easier to press the power button of the system unit.
When using a laptop, the function Zak actiondigging the cover
if you select Sleep in this parameter, 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 supply window, the Request a password on wake-up 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 supply tab, we can configure the parameter Pi button actioncomputer melting, so that when you press it, the computer goes to hibernation or hibernation, as well as completed its work. Select an option Nothing to do and when you press the power button with Wind ows 7, nothing will happen.
By default, the computer wakes up from sleep mode when the power button is turned on, if you want you can configure it to wake up from pressing any key on the keyboard or touching the mouse. To exit from sleep windows 7 using the keyboard or mouse, you need to go to the device manager and double-click the right mouse button on the desired device and go to the tab in the properties Power management and check the box Allow this device to wake the computer from standby.
If this number does not work for you, then your peripheral devices do not support this function, but you can find out for sure by typing in the command line powercfg -devicequery wake_from_any and all devices with which you can wake up the computer will be displayed.
What is the difference between Windows 7 sleep and hibernation, and what is hybrid sleep?
- Sleep mode: The computer saves information about your open applications in RAM and enters a low power mode, doing it quickly enough, but if your laptop is completely discharged, the computer will simply shut down and your open applications will simply close without saving the work.
- Hibernation: The computer saves all information about your open applications on the hard disk in the hiberfil.sys file and shuts down completely. The only difference is that during hibernation, the computer does not consume electricity at all, while in sleep mode, energy is still consumed. But to enter hibernation mode, as well as exit it, the computer takes much longer than when using hibernation mode.
- Hybrid sleep mode: combines sleep mode and hibernation, the results of your work in open applications are saved in RAM, but also on the hard disk and the computer goes into a low power consumption mode, so that when the battery is completely discharged, the results of your work will not be lost.
The simple answer is: The computer goes into sleep mode faster than hibernation, and it also comes out of sleep mode faster than out of hibernation.
You really need to be careful when using hibernation mode with some programs, for example, if you put to process or encode video files for several hours and at this time the computer goes into hibernation mode, the process will naturally be interrupted by an error. And when the computer wakes up from sleep mode, you have to start encoding again, in such cases, you need to turn off the sleep mode while such a program is running completely.
- Conclusion: It is preferable to use hibernation mode if you leave the computer for a long enough time. If, when using 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?"
Hibernation may not appear in this menu when hybrid sleep is enabled in the power settings. Power supply-\u003e Setting the power plan-\u003e Change advanced power settings, in these settings, we can prohibit the use of hybrid sleep mode, remove the password to wake the computer from sleep, and more.
In order to find out what modes your computer supports, type powercfg / a in the command line
Hibernation and Sleep Mode can not work in Windows 7if they are disabled in your BIOS, read our articles How to get into BIOS. They may also not work due to outdated drivers for the video card.
What is hibernation on Windows 7. How do I enable and properly configure this feature?
All modern personal computers have a "Sleep" button, but few people know what it means and how to properly use this function.
The computer is in sleep mode: what does it mean
Sleep schedule is a computer operating in a low power mode. Using the sleep schedule, you can quickly resume the work of your personal computer. Putting the PC into sleep schedule is often compared to the "Pause" button when watching videos: the computer immediately stops all actions and is ready to resume work at any time.
Sleep mode has two forks:
- Hibernation regulations
- Hybrid sleep mode
Hibernation mode
Hibernation schedule is a sleep mode designed specifically for laptops. The difference from the sleep mode is as follows: when switching to the sleep mode, the PC saves all the settings in memory, and, as already mentioned, the PC goes into the reduced power consumption mode. Hibernation affects a personal computer in a different way: when you enable this regulation, all actions and settings are saved on the hard disk of the device in a file called "hiberfil.sys".
Hibernation should be used if the PC is not going to be used for a long time and there is no way to charge the device. The mode will help conserve electricity.
Hybrid sleep mode
Hybrid sleep mode is mainly used on desktop PCs. Hybrid sleep consists of sleep and hibernation. Thus, all information and parameters remain both on the SSD and directly in the device's memory. If Hybrid Sleep Schedule is working, going to sleep puts the PC into Hybrid Sleep Schedule. On desktop PCs, hybrid sleep is always enabled.How to enable hibernation on Windows 7
To enable hibernation on the Windows 7 operating system, follow the instructions:
- Click the start menu icon
- Next, click on the arrow pointing to the right. The icon is located near the inscription "Shutdown"
- Select the required regulation:
Need to change sleep time on Windows 7
To change the sleep mode time in the Windows 7 operating system, follow the instructions:- Open the start menu
- In the search bar, enter "power supply" and open the appropriate tab
- After completing the previous step, the Power Options menu opens. Here you need to go to the panel on the left, and click on the inscription "Setting the transition to sleeping regulations"
- If you want the computer to go into hibernation after inactivity, refer to the "Put the computer to sleep" option and select the desired time interval, click on the "Save changes"
- To change the sleep mode time, click on the "Change advanced power settings" tab
- Click on the inscription "Sleep", click on the inscription "Sleep after" and enter the desired time
How to turn off hibernation on Windows 7
To disable hibernation on the Windows 7 operating system, follow the instructions:
- We go to the start menu and in the "Search" line enter "Electricity"
- You need to click on the inscription "Power plan settings"
- Next, you need to go to the "Put the computer into hibernation" tab, here you must select "Never", which will disable hibernation
- Next, you need to save the selected settings. To do this, click "Save Changes"
Possible Issues: Why Windows 7 Won't Go to Sleep
There are two most common problems:- PC automatically wakes up from hibernation or sleep mode
- Wake up the device at the same time
- To solve both problems, you need to go to the "Power supply" menu
- Click on the inscription "Power plan setup"
- Next, click "Change advanced power settings"
- You must open the "Sleep" tab
- Open the Allow Wake Timers tab
- Select "Disable"
- Save changes
Setting up hibernation on Windows 7: video
First, let's define that by hibernation we mean a mode in which the computer reduces power consumption, but does not turn off - all components remain on and ready to wake up.
The shutdown itself at night is definitely not harmful for the computer, as well as putting it into sleep mode.
From the point of view of electronics, in the case of putting into sleep mode (namely sleep mode, not hibernation), if it is a laptop, a situation may arise when the laptop overheats - for example, if for some reason it did not go into sleep mode, and then it also hangs, and you closed the lid - then it will be more difficult for coolers to draw in air (in most models, air intake holes are located not on the side, but in the same plane as the keyboard). If the laptop overheats, it will shut down. Overheating is bad for electronics, but it’s unlikely that your laptop will fail from one time.
But, strictly speaking, such a case is not very likely.
With a stationary PC, the problem of such overheating is unlikely to arise. But another problem may arise with it: if you use an HDD (an ordinary hard disk with a magnetic surface over which the read head "hovers"), and not an SSD, then a power outage (or even just a short-term "blinking"), if If you do not have an uninterruptible power supply connected, it could damage the hard disk because the read head will "fall" onto the disk and damage it. Then your hard drive will be scratched something like this: wikipedia.org The consequences can be different, and depend on where the read head falls - perhaps some files will simply become unreadable (the system will be sure that these files are there, because this is stored in the surviving part of the disk, but it will not be able to read the file, because it is exactly where the disk was damaged), and possibly if more important files are damaged (for example, system, or MBR - the master boot record, which is located in the first sector of the disk: wikipedia.org), the system may not boot at all.
Actually, many modern hard drives are able to handle this situation. But your drive may be older, or you may just be out of luck.
If at night there is a sharp power surge in the network, and your computer is not connected through a surge protector, this can also lead to problems (the system unit or something with it will burn out). Both a shutdown and a power surge can occur during the day, but if the computer works twice as long, then the probability of such an event may be slightly higher.
From a software point of view, if we are talking about Windows, then a long uptime (work without reboots) can lead to brakes in the system. Therefore, if your Windows runs for a month without reboots, it may start to glitch (or not). Therefore, sometimes rebooting the computer is useful in terms of software.
The on-off case is more interesting. When you turn on the computer, there is some power surge (which, by the way, this electronics is designed for). In case of wear and tear, such a jump can damage some PC components. In addition, if you have a regular hard disk installed, turning on or off means parking the read heads and putting them out above the working surface. The more this happens, the more wear and tear (this applies to all mechanical moving parts). The more wear and tear, the more likely it is to fail. But again, if you don't turn on the computer every five minutes, then this is normal computer use, and hard drives are designed for this.
Summing up - yes, if you start digging, you can give several arguments that potentially on-off can be more harmful to the computer from the point of view of electronics. But, by and large, this is saving on matches. Personally, for myself, I would not leave a stationary computer in sleep mode overnight because of a possible power outage, and a laptop because of possible overheating (with the lid closed). I would not take into account the nuances of voltage surges when turning on and off, because the electronics are more likely to become obsolete than the more frequent turning off and on will affect.
By the way, it is useful to mention also the third option - sending the computer into hibernation mode. In this case, the operating system saves everything in RAM to the hard drive and turns off the computer's electronics. The difference from a normal shutdown is that when you wake up the computer from hibernation, it will resume its state before going into hibernation. That is, all programs will be launched, the same tabs will be open in browsers, if you watched the video, it will stop at the same place where you stopped it, if the music was playing, it will continue to play, and even the clipboard will be the same what it was before you hibernated the computer.
Sleep mode is a low power mode that allows you to quickly resume normal power consumption mode (typically 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 is a low power consumption 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. Of all the power saving modes in Windows, the least amount of power is required to maintain Hibernation. 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 consumption mode. In the event of an unexpected power failure, the Windows operating system can easily recover data from the disk. If Hybrid Sleep is enabled, Hibernation automatically puts the computer into Hybrid Sleep. On desktop computers, hybrid sleep 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 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 enters hibernation mode, Windows flushes the contents of the RAM to the hard disk - to the hiberfil.sys file, and when turned on loads this file into memory. The file size is equal to the size of the RAM installed on the computer. Thus, deleting this file 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 click 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 you checked.
