Today, one increasingly hears the opinion that a computer, by analogy with a smartphone, which we put into sleep mode when locked, does not need to be turned off. Is this really so and is it worth giving up on a daily basis – we will tell in the article.

Economy Modes

According to the developers, if you do not turn off a modern computer, you can significantly extend the life of its components. To do this, as well as to save energy, there are three options: sleep, hibernation and hybrid sleep.


When switching to sleep mode, all information on the computer is stored in RAM, applications remain running. The operation of the device at the request of the user resumes as soon as possible. It’s like a pause on the drive: the computer goes into power-saving mode, but at the same time, it’s ready to continue working at any time. During sleep, power to the monitor, processor, and hard drive is cut off. The RAM continues to work, so a quick resumption of work is possible.

How to Enable Sleep Mode on a Laptop or Desktop Computer

  1. Go to “Start” and click on the gear (settings will open).
  2. Go to “System”.
  3. Go to “Power & Sleep”.
  4. Set the time after which you want to start the mode.


Another low-power option is hibernation mode. Initially, it was developed mainly for laptops. Unlike the previous option, when all documents are stored in RAM, here they are written to the hard disk, after which the computer shuts down. This is the most economical sleep mode. After power on, work is restored in seconds.

If power is lost during normal sleep, all data is lost. And in hibernation mode, they can be restored. The only negative point is the long loading of the device and the consumption of the hard disk resource.

How to Enable Hibernation on Laptop and Desktop

  1. Go to “Start” and select “Power Management”.
  2. In “Settings”, you need to select “Power and sleep”, then go to “Related settings” and click on “Advanced power settings”.
  3. In the “Power” tab, click on “What are the power buttons for”.
  4. In the “Shutdown options” section, the “Hibernation mode” box is checked.

After that, the corresponding icon will appear in the “Shut down or log out” menu.

hybrid sleep

The hybrid sleep mode is a compromise solution between the two previous options to save energy. Hybrid sleep is a combination of normal sleep and hibernation. It is often used on fixed PCs. All documents are stored in both RAM and hard disk. The computer switches to economical resource consumption. As with the normal sleep state, you cannot disconnect your computer from the network in this mode. In case of failure, the system can recover data, but it will not be regular recovery, but emergency recovery. Do not abuse.

How to Enable Hybrid Sleep on Laptop and Desktop

Since hybrid sleep is identical to normal sleep, it is activated accordingly. It should be noted that if the computer supports this function, it will be set by default.

The main advantages of the considered modes are the saving of electricity and component resources. In this case, the work of the computer resumes in a few seconds. Hibernation consumes the least amount of power, but like hybrid sleep, it reduces hard drive life.

Today, it is no longer necessary to turn off the computer. Using modes such as sleep and hibernation will save time during the daily startup of the computer and all work programs. Using these modes, you can save energy and your own time, as well as quickly return to tasks and restart the computer only after installing updates or software.
