Sleep is a power-saving state. Sleep saves all open documents and programs, and allows the computer to quickly resume full-power operation (typically within several seconds) when you want to start working again. Putting your computer to sleep is like pausing a DVD player: the computer immediately stops what it’s doing and is ready to start again when you want to resume working.
To put your computer to sleep, click the Power
button on the Start
menu or click the arrow next to the Lock
You can typically put a mobile PC to sleep by closing its lid. Some computers also have a physical sleep button on their cases, often located near the power switch.
Depending on your computer's power management settings, you computer may also automatically go to sleep after a period of inactivity to conserve energy. To adjust these settings, see Change, create, or delete a power plan (scheme).
While your computer is asleep, its hardware lights may slowly flash or change color. This is normal.
On most computers, you can resume working by pressing the power button.
However, not all computers are the same. You may be able to wake your computer by pressing keys on the keyboard, clicking your mouse button, or opening the lid on a mobile PC. Check the documentation that came with your computer, or go to the manufacturer's website.
