Power management
Power management helps you reduce the electricity consumption of yourcomputer by regulating power supply to the various components. The BIOS setup program and the operating system allow you to configure when the power supply to certain components should be reduced or cut off.
Some common power-saving states in Microsoft Windows are:
- Sleep—Sleep is a power-saving state that enables a computer to quickly resume full-power operation (typically within a few seconds) when you want to start working again.
- Hibernation—Hibernation puts your open documents and programs on your computer storage, and then turns off your computer.
- Hybrid sleep—Hybrid sleep is a combination of sleep and hibernation. It puts any open documents and programs in memory and on your computer storage, and then puts your computer into a low-power state so that you can quickly resume your work. When hybrid sleep is turned on, putting your computer into sleep automatically puts your computer into hybrid sleep.
- Shut down—Shutting down your computer helps when you are not planning to use the computer for a considerable period of time. It helpskeep the computer secure and also saves more energy. Shut down your computer before adding or removing hardware inside the computer.
Shutting down is not a recommended when you need to resume work quickly.
