What is the difference between sleep and hibernation in Win7 system, and how to reboot it when sleep

Sleep is the process of putting a data program that is currently running in memory and disappearing when the power is off.

Hibernation is to save the data that is currently in the running state in the hard disk, and the power supply of the whole machine will be completely stopped.

Read speed comparison:

Hibernation is the storage of data on the hard disk, which is much slower than memory, so it is relatively slow to go to sleep and wake up.

Security Comparison:

The data stored in the memory of the sleep disappears when the power is off, and the data is already safe in your hard drive when it is hibernated, or even completely disconnected from the power of the computer.

Hibernation is to store the process (program) in memory, can quickly enter the working state, generally takes about 1-2 seconds, and sleep is to store the process (program) in the hard disk, relative to hibernation, it takes about 10 seconds to enter the working state, when the boot is turned on, the machine will execute the process (program) when you sleep or sleep, sleep can not last for a long time, if the sleep time is too long, the computer will automatically save the process (program) in the hard disk, when sleeping, You only need to touch the computer keyboard or mouse to wake up to work, and you must press the power button when sleeping.

Sleep and hibernation are not considered shutdowns. Thank you.

Sleep is standby, and hibernation is shutdown.

Sleep: The system will turn off the power supply of all devices except the memory, press any key or move the mouse, the system will wake up, and return to the program and state that was opened before sleep. Hibernation:

The system will save the open program and status, and then cut off the power and keep the power light. Press any key or move the mouse as well, and the system will wake up and return to the program and state that was opened before hibernation. Log out:

It can be understood as a quick computer restart, which will empty the cache space and registry information of the current user, and cannot replace the restart, such as the installation of some hardware drivers that need to be restarted, and cannot be replaced by logout.

Sleep: As long as you move the mouse or keyboard, you can turn on the computer, which is convenient.

In the dormant state: the power can only be turned on by pressing the power switch, which is more power-saving.

If you only want to sleep function, then in the operation, enter powercfg -h off, and the sleep function will be turned off, and then there will only be sleep options in the start menu, and then click sleep, the computer will have a sleep state, and it will not turn to sleep.

If you want to hang up in an online game, you can't choose either, sleep is to save your progress in memory, sleep is to save it on your hard drive, and both are no longer running.

If you want to hang up the game, you can only turn on it normally, but you can turn off the monitor.

Sleep: Turn off most of the hardware power supplies you don't need (e.g., monitors, network card drivers) and power the memory.

Hibernate, save the files in memory to the hard disk, and then shut down.

If you want to hang up + save power, you can't do both;

However, you can use Windows 7 Optimizer and enable "Away Mode", which will keep the network card not turned off.

Hibernation: save, power off, boot recovery;

Sleep: Uninterrupted power, power on and resume.
