Notebook power management

1. sleep

Sleep is an energy-saving state that allows your computer to return to full power quickly (usually in a matter of seconds) when you want to start working again. Putting the computer to sleep is like pausing the DVD broadcaster: the computer immediately stops the current operation and is ready to restart when you want to continue working.

two。 Dormancy

"hibernation" is a power saving state designed mainly for notebook 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, and then shuts down the computer. Of all the energy saving states used by Windows, hibernation uses the least power. 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 period, you should use hibernation mode

3. Mixed sleep

"mixed sleep" is mainly 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, and then puts the computer into a low-power state so that work can be resumed quickly. This way, in the event of a power failure, Windows can restore your work from the hard drive. If you turn on mixed sleep, let the computer enter the sleep state at the same time, the computer automatically enters the mixed sleep state. On desktop computers, mixed sleep is usually on by default.

3. Shutdown

Stop the operation of all equipment and cut off power. Zero power consumption during shutdown
