Surely, users of the Windows 7 operating system noticed that this version of the operating system has a sleep mode and a hibernation mode, which at first glance are no different from each other.
Sleep mode
Sleep mode is a special mode of operation of a personal computer, in which there is a reduced power consumption. This mode allows you not to turn off the computer and quickly resume the computer at the request of its owner. At its core, hibernation is a kind of "pause" that stops all running processes and applications, but at any time the computer can return to work.
Hibernation mode
Hibernation mode, in turn, is the same low power mode. Its only difference from the previous mode is that in hibernation mode all open documents, files and programs are saved on the hard disk of a personal computer in a special file (hiberfil.sys). After all the information has been saved, the computer will turn off. The most important advantage of this mode is that it requires the least amount of electricity to maintain hibernation mode, unlike all others. At first, this mode was developed exclusively for laptops. Of course, in this regard, it turns out that it is most reasonable to use it on these devices. For example, if you are not going to use your computer for a long time and you are unable to recharge the battery, then it is recommended that you put your laptop into hibernation mode.
It is worth noting that no matter what state the user chooses, be it sleep or hibernation, in both these cases, the user's computer should not be de-energized (information may be lost). Naturally, if this happens, the system can recover data directly from the disk, but such recovery is not standard (during this, an intense load on the hard disk of a personal computer occurs), respectively, if this is abused, the system can be subject to various negative influences.
On most computers, you just need to press the power button to resume it. But since all computers are different, the way you can resume work may be different too. To return the computer to normal operation, you may need to press any key on the keyboard (or a dedicated power key), press a mouse button, or open the laptop lid.
As a result, it turns out that the difference between these two modes is practically the same, but it is believed that it is better to use hibernation mode.
