Sleep mode is a low-power mode that allows operation to quickly resume normal power consumption (usually within a few seconds) upon user demand. Putting your computer into sleep mode is similar to pressing the Pause button on a DVD player: the computer immediately stops all operations and is ready to continue working at any time.
Hibernation Mode is a low power consumption mode designed primarily for laptops. When entering sleep mode, everything open documents and the settings are saved in memory and the computer goes into a low-power mode, and when it enters hibernation mode, all open documents and programs are saved to the hard drive and then the computer turns off. Of all the power-saving modes used in Windows, Hibernate mode requires the least amount of power. If you do not plan to use the laptop 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 is designed primarily for desktop computers. Hybrid sleep mode combines sleep mode and hibernation mode because all open documents and programs are stored in memory and on the hard drive and the computer is put into a low-power mode. If there is an unexpected power failure, the Windows operating system can easily recover data from the disk. If 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
The choice of mode is up to the user. This article will suggest the option of disabling "Hibernation Mode" and deleting the hiberfil.sys file
How to disable "Sleep mode"?
To disable Sleep Mode, do the following:
You can also disable the sleep function. Select "" And in the window, find sleep mode and turn it off.
How to remove hiberfil.sys file?
After disabling "Sleep mode", you can delete the hidden file hiberfil.sys
File hiberfil.sys created by the operating system for the functioning of hibernation mode. When the computer goes into sleep mode, Windows resets the contents of RAM to the hard drive - into 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, by deleting this file, you can significantly increase free space on your hard drive. But in Windows 7, even with Sleep mode disabled, the hiberfil.sys file is not deleted and remains on the hard drive. To delete this file, you must have Administrator rights. Click Start - Run, or Win + R keys, and enter the command
powercfg -hibernate -off or powercfg -h off
Click 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 turning on show hidden files. Start - Control Panel - Folder Options - View
Select "" and uncheck the "" do not forget to press Apply And OK. We 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.
Hello! I haven’t written anything useful on the blog for two days; I was busy with one very important thing, which I’ll tell you at the end of the article :). And I'll tell you right now how to disable sleep mode And turning off the display in Windows 7. You probably know that if you leave the computer alone, do not press the keys or touch the mouse, then after a certain time the screen will turn off and it will go into sleep mode, all this is done to save energy.
In the control panel we look for “Power supply” and select it.
Automatic screen shutdown and sleep mode can be configured differently for the two plans: "Balanced" This plan is most often activated on desktop computers and laptops connected to the mains. AND “Energy Saving”, this one usually turns on automatically when you disconnect the laptop from the power supply. Let's set up for “Balanced” mode, click opposite it.
As you can see, I have the screen turn off after 10 minutes, and automatically go into sleep mode after 30 minutes. All you need is to simply change the time, or completely disable these actions by selecting “Never”. After changing, don't forget to click the button “Save changes”.
Incomplete shutdown of the OS and hardware. Designed to speed up computer boot time. Programs do not turn off, documents do not close. Therefore, loading occurs in a matter of seconds. More like switching off than sleep. Almost no electricity is consumed and there is no noise from the device. The main difference from sleep is that in sleep mode open files and programs are recorded in the OP. For hybrid shutdown, this is done using HDD. Especially convenient for laptops running on battery power.
Not many people know about hibernation mode on a computer.
Enabling on Windows 7
Hibernation in a laptop first appeared with the release of Windows 7. It is also present on “eights” and “tens”. Convenient when you need to transport a laptop when not in use, and then quickly get to work. It is also good for home devices running on network power. In this state, the device does not make noise and turns on quickly. To enable hibernation in Windows 7, do the following:
- Go to the Start menu;
- Click the arrow next to the Shut down button;
- Select the appropriate item in the context menu.
If you need to turn off the computer using the keyboard, it is called using the command line. Press Win+R and in the Run field that opens, type cmd. Command Prompt will open. Enter powercfg –hibernate on. You must have PC Administrator rights.
Hibernation and sleep: differences
The difference between hibernation and sleep is significant. In sleep mode, work is paused. The screen, cooler and hard drive turn off. On RAM and other components are supplied with some voltage. The computer continues to consume power. Applications are open, programs are running. By moving the mouse or pressing a button, you will see the system in the state it was in when it went to sleep.
During hibernation, the PC is completely de-energized. Energy is supplied only to the crystal oscillator, which allows you to maintain the time and date in the BIOS. When entering PC mode, it writes to the hard drive an exact copy of the OS at the time of suspension. Turning on takes 10 - 15 seconds, while from sleep - 1 - 2. Operation will also be restored from the point where the system went into hibernation. The battery will not be discharged even over a long period of time.
For each system, a state is provided in which the system goes into the so-called sleep, in which all active processes stop before waking up. Sleep mode in Windows 7 is as integral a part of the system as turning it on and off. In this article we will look at the main points of this function - how to turn sleep mode on or off in Windows 7, the main errors and problems.
Turning on and off
Sleep mode is primarily aimed at saving energy on your PC. If it is important for a laptop to preserve battery charge, then for a desktop computer this function may interfere. In any case, each user has his own goals for using a computer.
You can turn sleep mode on and off in the Panel Windows management, where the main system configuration is performed.
- To do this, find "Start" in the taskbar and go to Control Panel.
- Or in the Run window (shortcut Win + R) write control and click OK to go to Control Panel.
The device's sleep is controlled by the power settings. It is in the power plans (or diagrams) that the sleep settings, device on/off, and other Windows settings related to saving energy and turning off the device are specified.
- Select the viewing option Large or Small icons and go to settings "Power supply".
Setting up sleep mode on Windows 7 is done for each individual scheme, and you can either change the sleep time (increase or decrease) or completely disable this functionality.
- Opposite the scheme you are using, click on the button called "Setting up a power plan".
- Where can you configure required time not only sleep, but also turning off the monitor or display after a certain amount of time has passed.
- In meaning "Put the computer into sleep mode" select the desired time, but if you need to turn it off, select “Never”.
- For laptops, there will be a choice of sleep output, both when powered by a battery or from the mains.
- Also, if the selected time gradation does not suit you, then you can configure the transition to sleep mode Windows computer 7 and exit from it in the electrical circuit settings. To do this, in the same window, click "Change power settings".
- In a new window, expand the “Sleep” branch, expand “Sleep after” and specify the desired time of PC inactivity so that it automatically falls asleep. Time is indicated in minutes.
This is interesting! Many users ask, Windows 7 hybrid sleep mode, what is it and how is it different from regular sleep mode? Hybrid mode is an analogue of hibernation in laptops, only created for personal computers. Hibernation - energy saving, in which Windows saves all active processes and applications in the hard drive memory and actually turns off.
The difference between normal sleep and hibernation is that if you turn off the computer while in sleep mode, all open files will be lost because Windows is paused. And during hibernation, if you turn on the computer, all applications will be restored, as they were saved to the drive. Hybrid sleep mode is enabled by default on PCs.
Errors
Let's consider the most common errors, the absence of a sleep mode in the shutdown list, when the computer does not turn on or, on the contrary, does not fall asleep, as well as the reasons that may interfere with this.
Sleep missing from PC shutdown options
Sometimes, purely installed Windows, users may not find Sleep or Hibernation mode in the general shutdown list. This error may be due to the lack of a video card driver, which is partly responsible for the sleep of your device.
To correct this situation, you should do the following:
- Open first "Device Manager"- then find the Run item (Win+R) and write devmgmt.msc, then click on OK.
- Expand the list of video cards - select a discrete video card (some devices have 2 video adapters - built-in and discrete, discrete is usually more powerful and works in priority).
- Right-click on it and select "Update driver"
- The Windows system should automatically find the latest driver in the update center, if, of course, it was provided by the manufacturer of this video card. If there are several video adapters, update for all devices.
- If no fresh drivers were found or simply did not help, you need to update the drivers yourself. To do this, go to the device manufacturer's website and search for the model of your video adapter.
Then install the driver. In case of errors or failures, it is recommended to perform a clean installation of the driver. Either through the installer settings (a clean installation item, in which the old driver is completely removed and a new one is installed) or through the Display Driver Uninstaller utility, which can also remove and clean the video adapter driver for subsequent installation.
- After installing the new driver, restart your PC and make sure that sleep mode (sleep) is now active.
Important! If the above tips did not help, and there is still no sleep mode, you need to install the chipset driver, which is responsible for the device’s power plans. For some motherboards, there is a separate ACPI power driver that should already be included in the chipset driver
You can download the chipset or ACPI driver from the website of the motherboard or laptop manufacturer.
PC won't wake up from sleep
There have been cases when Windows 7 did not wake up from sleep mode when pressing the keyboard or mouse. Let's look at this case in more detail.
First of all, check whether the keyboard and mouse can wake the device from sleep. To understand this, open "Device Manager"- then the Run window (Win + R) and enter devmgmt.msc, then click OK. 
First, let's check the keyboard. Expand the "Keyboards" list, right-click on the keyboard and select Properties. In the window that opens, go to the tab "Power Management". Make sure the checkbox next to the item is checked “Allow the device to wake the PC from standby mode”.
We check the mouse in the same way.
Important! Often the cause of this error may be a conflict between the driver and the enabled fast startup, which is absent in Windows 7. But in Windows 8 and higher, the error is “cured” by disabling this function and updating the ACPI driver.
PC won't sleep
Sometimes after Windows updates or drivers, the device does not go into sleep mode on Windows 7 after the required period. In this case, you need to check whether all settings are correct and whether sleep mode is enabled.
- First, try hibernating your PC yourself.
- If everything is fine, try setting the sleep mode value for 1-2 minutes and wait a little. If during this time the PC “does not fall asleep,” the problem must be solved.
- First, let's disable wake timers and the prohibition on entering sleep mode for multimedia. To do this, go to the advanced settings of the power plan and in the Sleep branch, for the parameter "Allow wake timers" For all items, set the value to “Disable”.
- In the same settings, only in a branch Media options, for parameter "At public access to multimedia" set the values "Prohibit transition..."
- After this you need to open the window Command line, in the Run window (Win+R) enter the cmd command and click OK
- We will need to find out which devices are preventing the computer from falling asleep. To do this, enter the command:
Powercfg -devicequery wake_armed
A list of devices that may be preventing the device from entering sleep mode will be displayed. To disable this feature, enter the command:
Powercfg -deviceenablewake "value"
Where instead of “value” you need to enter a device from the previously proposed list. It is worth noting that you must enter the same as written in the list, for example:
Powercfg -deviceenablewake “HID Keyboard”
- If none of the proposed options helped and the computer still does not enter (does not turn on) sleep mode in Windows 7, then try updating the video card and ACPI drivers from the “PC does not wake up from sleep” item.
In this article, we figured out how to set automatic sleep mode in Windows 7, setting the transition (required time), as well as the main problems associated with this function.
Have a great day!
