Hibernate, Sleep & Hybrid Sleep in Windows 7
With the advent of Windows 7, many are get accustomed to new features like hybrid sleep which are extra features over the XP. In XP you’d have Standby, which changed to Sleep in Windows 7 and an additional feature called Hybrid Sleep got added.
Sleep allows to quickly resume full-power operation (typically within several seconds) which is a power-saving mechanism, when you want to start again. Putting the PC to sleep is like pausing the DVD player. The PC immediately stops its work and is ready to start again when you want to resume.
If the power fails, all the un-stored data vanishes and you are at the mercy of power. But this helps if you want to save energy and want a quick recover from this energy-saving mode.
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.
As a conclusion from the above we can understand, Sleep and Hibernation is for laptops. Hybrid sleep is very useful for desktop computers.
