The following are some frequently asked questions about sleep and hibernation.
What is the difference between hiding sleep, dormancy, and mixed sleep?
Sleep> is a state of energy saving that allows the computer to quickly resume full power when you want to start working again (usually at Within a few seconds). 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 your hard drive, then shuts down your computer. Hibernation 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 resume 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 desktop computers, mixed sleep is usually turned on by default.

If the sleep or hibernation is not available, it may be due to one or more of the following reasons:
Your video card Sleep may not be supported. Update the driver for your video card, or check the information that came with your computer about the video card and supported drivers.
Some settings are managed by the system administrator.
The sleep state and other power-saving states in the computer's basic input/output system (BIOS) are turned off. To turn on sleep, restart your computer and enter the BIOS setup. When you start your computer, a description usually appears on the screen that prompts you to press the key or keyboard shortcuts you want to enter during the BIOS setup process. Since not all computer manufacturers use the same BIOS, the keys used to enter the BIOS settings will vary. To learn more, check the information that came with your computer or go to the manufacturer's website.
If the Hibernate option is missing, you may have turned on Hybrid Sleep.

Check the documentation that came with your computer or go to the manufacturer's website.
Does sleep eventually exhaust the battery of a laptop?
The amount of power consumed by sleep is very small, equivalent to the power consumption of a night light. If the battery is critically low while the laptop is asleep, Windows automatically puts the computer into hibernation mode.
Is my data safe when my computer is asleep?
