Explanation:
Sleep is a power-saving state that allows a computer to quickly resume full-power operation (typically within
several seconds) when you want to start working again. Putting your computer into the sleep state 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.
Hibernation is a power-saving state designed primarily for laptops. While sleep puts your work and settings in
memory and draws a small amount of power, hibernation puts your open documents and programs on your
hard disk, and then turns off your computer. Of all the power-saving states in Windows, hibernation uses the
least amount of power. On a laptop, use hibernation when you know that you won’t use your laptop for an
extended period and won’t have an opportunity to charge the battery during that time.
Hybrid sleep is designed primarily for desktop computers. Hybrid sleep is a combination of sleep and
hibernate—it puts any open documents and programs in memory and on your hard disk, and then puts your
computer into a low-power state so that you can quickly resume your work. That way, if a power failure
occurs, Windows can restore your work from your hard disk. When hybrid sleep is turned on, putting your
computer into sleep automatically puts your computer into hybrid sleep. Hybrid sleep is typically turned on by
default on desktop computers.
