What is the difference between computer hibernation and sleep

If the computer is turned off, the computer will lose power, and if the computer is turned back on, the operating system will re-read the system files. Sleep, compared to hibernation, this mode also saves the current worker in memory, but it has not been powered off yet.

If you don't use the computer for a long time, you can choose to shut it down, which will be more environmentally friendly and energy-saving. Sleep because the power has not been turned off, so move the keyboard, mouse is very able to wake up the system, more suitable for large files or temporarily leave the computer, so that when you come back, you can immediately turn on the computer state.

PC sleep mode is a mode in which your computer is in standby and can be set from your computer's Power Options menu. It can save you power, relatively speaking, it is very "environmentally friendly", which can save the cumbersome boot process and increase the life of the computer.

Hibernation: It is to save the program that is running on the current operating system on the hard disk, and then power off.

Sleep: After the system goes to sleep, the system backs up all the data in the memory to the hard disk (similar to hibernation). Then turn off all devices except memory'power supply so that the data in memory is still maintained (similar to standby).

1. The sleep of the desktop (hybrid sleep off) means that all devices except the memory are powered off, and the memory is only on the DC power supply (there is no clock input, which is very important), and the power supply to other devices is restored when it wakes up, and it returns to the working state.

Desktop hibernation, XP also has this function, which stores all the data in the memory into a contiguous space on the hard disk and cuts off all power. During recovery, the memory data temporarily stored in the hard disk is restored to the memory and returned to the working state.

Switch sleep command: turn off system hibernation: cmd-->powercfg -h off"; Enable system hibernation: cmd -->powercfg -h on".

2. In the power plan, there are different settings for the time of entering sleep and entering hibernation, of course, according to the logic of normal people, the former is less than the latter. Therefore, when you go to sleep and do not wake up until the sleep timer reaches the point, the system will automatically store the memory data on the hard disk, disconnect all device power, and enter the sleep state.

Blended sleep, i.e. when blended sleep is turned on. The moment you start sleeping, the data in the memory is stored in the hard disk at the same time, and the memory is still powered on and enters a normal sleep state. In the event of an unexpected power failure, the data from the hard disk will be restored to memory at the next boot, which is the principle of hibernation.

Of course, if the sleep timer is triggered, it will automatically go to sleep, and there is no need to dump data at this time, because it has already been done before. Therefore, hybrid sleep = sleep + hibernation, which can prevent data loss due to sudden power failure.

The differences between computer sleep and hibernation are as follows:

Sleep] is an energy-saving state that allows you to enter the system quickly, but it requires a certain amount of power consumption due to the need to keep data in memory; [Hibernation] can further reduce power consumption, store all data in the hard disk, if you do not use the laptop for a long time, you can choose to hibernate mode.

Here's a closer look:

1. [Sleep] is an energy-saving state, if you need to use it, you only need to touch the mouse or open the notebook to immediately open the original interface, no need to re-read the process of entering the system, this is because the memory is still not powered off when sleeping, so the operation you just now is still in the memory, but the power consumption of running is relatively low.

2. [Hibernation] can further reduce power consumption, after you enter sleep, the system will store the documents and content-related data you open into the hard disk, which is due to the loss of data in the memory after power failure, and then the system will automatically shut down the computer, which requires you to press the power button to be able to re-wake up and enter the system.

3. If you will not use your laptop for a long time and will not charge the battery during that time, you should use sleep mode. When sleeping, the data is also saved, but it has been saved to the hard disk, and the power can be cut off, which is equivalent to shutting down, but when it is restored, it can be restored to the working state before sleep.

The differences between computer sleep and hibernation are: different power consumption, different speeds, different data saving, different security, and different usage scenarios.

1. The power consumption is different.

The biggest difference between computer hibernation and sleep is that they consume different powers. When your computer is asleep, your computer turns off your display and hard drive, but your memory and other hardware devices remain running. This means that the power consumption of the computer in the sleep state is very low, but the computer can be restored to working state very quickly.

2. The speed is different.

When the computer is asleep, the computer can be restored to working state very quickly. Just press the keyboard or mouse, and the computer will wake up instantly. Conversely, when the computer is asleep, it takes longer for the computer to return to a working state.

You'll need to press the power button or restart your computer to wake it up.

3. Data storage is different.

When your computer is asleep, your computer saves all your data to memory. This means that when the computer resumes from sleep, all the data is still in memory. Conversely, when a computer is asleep, the computer saves all data to the hard drive.

This means that when the computer resumes from hibernation, it needs to read data from the hard drive.

4. Security is different.

When the computer is asleep, the computer can be quickly restored to working condition, but it also means that the data on the computer can be easily accessed by others. Conversely, in the dormant state of the computer, the computer needs to enter the password to recover from the dormant state. This means that your data is more secure when your computer is asleep.

5. Different usage scenarios.

Computer sleep is suitable for short breaks, such as a lunch break or a short time away from the computer. Conversely, PC hibernation is suitable for longer periods of rest, such as overnight stays or long periods of time when you don't use your computer.

The differences between computer sleep and hibernation are as follows:1. The location of the saved data and the wake-up method are different.

When the computer is asleep, all work can still be carried out normally when the computer is woken up again. Just click on the boot button and you will be able to enter the recovery process in no time. When the computer is asleep, all the data in the working state of the computer is saved in the corresponding memory.

When you need to wake up, you only need to press the mouse or keyboard to quickly recover.

2. The length of time away from the computer is different.

After the computer is in a dormant state, all computer accessories will not be powered on, and the power consumption is small, if you do not use the computer for a long time, you can choose to put it in a sleep state. If you leave the computer for a short period of time, you can put it to sleep, which can save power consumption and resume work quickly.

3. The working state is different.

Compared with the computer sleep state, this mode saves the current working programs in memory, and the computer is in a working state without powering off. Since the computer is not powered off, you can re-wake up the computer system with a slight movement of the keyboard or mouse. When the computer is asleep, the working state of the computer is in a power-off state, and you need to click the power button to restore when you wake up the computer.
