1. What is the difference between shutdown, hibernation and sleep?
1. shutdown
Shutting down must be the most familiar method for everyone. When shutting down, the system first closes all running programs, and then closes the services in the background of the system.
Then, the system requests the mainboard to shut down, and the mainboard cuts off the power supply, so that the power supply cuts off the power supply to most devices (only some internal parts will still maintain the power supply, such as clock, USB power supply, etc.). Finally the computer shuts down completely.
2. Sleep
To keep a computer running while shutting it down. When using hibernation, Windows will save the data in the memory to a file in the root directory of the system disk on the hard disk (this file can be understood as a "mirror" of the memory state), and then shut down the computer. So after hibernation, even if the power is cut off, it will not have any impact on the computer or data.
Advantages of Hibernation
① Among all energy-saving states used by Windows, hibernation consumes the least amount of power and is not afraid of power failure.
② When you start the computer again, you can return to the place you left off (although it is not as fast as the sleep option).
Disadvantages of Hibernation
This option is designed for laptops and may not be available for all computers.
3. sleep
After the computer enters sleep mode, Windows will first save the data in the memory to the hard disk, and at the same time cut off the power supply of other devices except the memory. When it is time to restore, if the power is not cut off, the system can immediately return to the place where it left off; if the power outage is caused by insufficient power, then you don’t have to worry about losing the content you need in your work due to the battery running out. Because Windows automatically saves everything and shuts down the computer.
Benefits of sleep
Conserves energy: Sleep mode minimizes your computer's energy consumption by shutting down most of your computer's hardware and software, which reduces energy consumption.
Fast Resume: Sleep mode provides a quick way to return to a previous working state because it saves the computer's state in memory instead of shutting down the computer completely.
Protect data: Sleep Mode protects your work in progress and open files as it keeps them in memory to prevent data loss.
Extended battery life: Sleep mode extends battery life because it reduces energy consumption by putting the computer into a power-saving mode when it is not in use.
Sleep Disadvantages
If the power is cut off halfway, the recovery speed from the hard disk will be slower. May have some impact on system performance and battery life.
2. When to shut down/hibernate/sleep?
When do I need to shut down?
1. It is written in Microsoft's technical support that the Windows system does not need to be turned on and off frequently during daily use. Two exceptions are: ① adding or upgrading hardware (such as installing memory, sound or video cards, disk drives); ② adding a printer, external drive, monitor, or other When using a new hardware device, you need to turn off the computer first, then disconnect the power supply, and then continue to upgrade or operate.
2. If the computer is not used for a long time, we can save the programs and files and then turn off the computer due to battery maintenance considerations.
When to use hibernate mode?
Use hibernation if you know you won't be using your computer for an extended period of time, and charging the battery won't be possible during that time.
When should sleep mode be used?
Based on the fact that the computer consumes very little power in the sleep state and can quickly enter the system to resume work, so when you need to leave the computer for a short period of time, such as drinking a cup of coffee, taking a nap, going to the bathroom or commuting, etc., just Great for using sleep mode.
3. Ultimate advice
Shutdown, hibernation, and sleep all have their own advantages and disadvantages. If you often need to turn on the computer to handle work, you can choose sleep; if you don’t use it for a long time, you can choose hibernation or shutdown according to your own situation.
