Putting your computer to sleep is like pausing a DVD player: the computer stops working immediately and is ready to continue working.
Hibernation> is a power saving state designed primarily for portable computers.
Sleep usually saves work and settings in memory and consumes a small amount of power, while hibernation saves open documents and programs to the hard drive, then shuts down the computer.
Hibernate uses the least amount of power in all power-saving states used by Windows.
For laptops, if you know that you will not be using it for a long time and it is not possible to charge the battery during that time, you should use sleep mode.
<quo;Mixed sleep" is primarily designed for desktop computers.
Hybrid sleep is a combination of sleep and hibernation - it saves all open documents and programs to memory and hard drive, then puts the computer into a low-power state so that it can be quickly resumed.
This way, if a power failure occurs, Windows can recover your work from the hard drive.
If you turn on Hybrid Sleep and put your computer to sleep, the computer automatically enters a mixed sleep state.
On a desktop computer, mixed sleep is usually turned on by default.
