What is the difference between Sleep and Hibernate in Windows?

Sleep mode is a power saving state that stops all actions on the computer. Any open documents and applications are moved to the system memory (RAM) and the computer goes to a low-power state. This is similar to pausing a movie DVD. The computer is still powered on, but uses less power. Devices such as monitors also use sleep or standby mode to reduce power consumption.

Waking the computer from a sleep mode allows you to quickly resume normal, full-power operation within a few seconds.

To wake up a computer or the monitor from sleep, standby, or hibernate, move the mouse or press any key on the keyboard. If this does not work, press the power button to wake up the computer.

NOTE: Monitors will wake up from sleep mode as soon as they detect a video signal from the computer. If the monitor does not wake up from sleep mode, ensure that the computer is not in sleep or hibernate mode.
