Each person has a different attitude to the computer: some prefer to disconnect it from the network after each session, others force it to work day and night. The Internet is full of articles that discuss this topic, but the information in them is different. In this regard, users still do not know exactly how often to unplug the computer from the outlet, whether to turn it off at night and whether the constant switching on of the equipment is harmful.

What is the difference between different computer modes?
To answer this question, is it possible to leave the computer on at night, it is worth considering the background modes of this device. As you know, there are only three of them:
- full shutdown;
As the name implies, the computer shuts down completely: all its systems are inactive. In this case, the computer practically does not consume electricity, if its wire is still in the outlet.
To start a new session, you need to turn on the PC and wait for the system to fully boot. Depending on the power of the device and the load of its memory, this process can take from several seconds to 2-3 minutes.
You can use the shutdown mode if you do not plan to use the computer for a long time.
If the device is not used for 5–10 minutes, it goes into sleep mode, that is, into a state of reduced energy consumption. The monitor is turned off, as well as some other parts of the computer, fans, for example, noises are heard from the system unit. In fact, the computer turned off, but after it wakes up, all open programs and windows will be started and opened again.
If at this mode the laptop battery is suddenly discharged, the user will not lose any changes, since the OS will automatically save all changes before shutting down.
Sleep mode is recommended in cases where the computer will not be used only for a very short period of time (for example, during a lunch or rest break)
In hibernation mode, the computer is turned off, but all data on its current state is reset to the hard disk. This dramatically reduces the amount of energy consumed (it is required only to illuminate the buttons).
This mode is more economical than sleep, but after exiting from hibernation, the computer turns on much slower than after hibernation.
Hibernation is relevant to work on a laptop, when you need to take a long break, but without leaving important programs, but with preservation of charge. In this mode, the battery is almost not discharged.
After downloading, all previously used files and pages open again, you can continue working with them.
What happens if you never turn off the computer
Many people use computers both day and night, practically without shutting down and rebooting it. Still, the computer must be turned off at night, otherwise a dismissive attitude to technology can lead to:
- System “wake-up”: OS can be updated only after a full reboot of the device. If it is always on, the system eventually begins to “slow down”.
- Malfunctions of individual items. Most often due to power surges in the network fails the power supply.
- Fast battery wear (relevant for laptops).
In addition, a permanently turned on computer is more susceptible to hacking and virus entry.
Do I need to unplug from the outlet
If the PC is used daily, there is no need to turn it off. On the contrary, it will have a negative effect on the state of the plug. If you do not plan to use your PC for a long period of time (for example, during departure), then it is better to turn off the device from the network completely.
Many people think that if you do not pull the plug out, the computer will consume a lot of energy even when it is turned off. This opinion is incorrect. Energy consumption is there, but it is so small that it can hardly be fixed.
The rules for working with a computer depend on its type, model, as well as the frequency of operation and other factors. If you use a PC every day, you can use hibernation or hibernation. In other cases, the computer is better off.
