Most modern users in order to temporarily shut down a laptop or netbook use the so-called sleep mode or even leave the device turned on, spending not only electricity, but also far from an infinite battery life. At the same time, few people think about the meaning of the mysterious "hibernation" function, which can often be enabled through the same menu as the sleep mode, and a very small number of users know the difference between sleep and hibernation modes, and which one is beneficial to use in one way or another. situations.
How is sleep mode different from hibernation?
In order to understand how one function differs from another, it is necessary to understand their properties and main purpose. Sleep mode, for example, allows you to:
- quickly return your computer to a working state;
- reduce electricity consumption;
- remember the current state of the system.
Important!Contrary to popular belief, the devices still consume energy even in a "sleepy" state. For example, a laptop is able to “sleep” in this mode for about 12 hours, and after that the battery will still be discharged.
In order to bring the computer out of sleep, simply click the mouse button or press any key on the keyboard.
As for the hibernation mode, widely and for a long time used on laptops, netbooks, tablets and other mobile equipment, it allows you to quickly restore work without waiting for the full launch of all applications that were active in the system at the time of the transition, and All open windows and programs are saved.
In the sleep state do not work:
- HDD;
- cooling system;
- screen.
In the hibernation state, the entire device is de-energized, with the exception of a special generator responsible for displaying the correct time data in the BIOS. When you switch to the mode, the image of the RAM is copied, and when you exit it, this copy allows you to fully and accurately return to the "original" system state.
Which mode is better for a laptop
Many users, after reading the above, may have a logical question about which of the modes is better suited for laptops or other mobile equipment. An unequivocal answer to this question can not be, because each of them has its own advantages and disadvantages, and if one was better and more convenient in all cases, then the second would simply be excluded from the standard functions of the device.
If the user cares about saving the system and the battery of his laptop as long as possible, then he will prefer to use the hibernation function, because it helps to save battery power and does not adversely affect its "resource".
As for sleep, this function is more like a "pause": in fact, all systems continue to work, but the device does not perform basic functions. According to the assurances of many users, the sleep mode does not actually affect the operation of the battery at all, and laptops can never be virtually turned off simply by putting them into a "dream". This statement is quite true for devices that most of the working time have direct access to the power grid and the possibility of constant charging.
