Windows 7 provides several options for conserving power when you are not using your PC. These options include Sleep, Hibernate, and Hybrid Sleep and are very useful if you are using a laptop. Here’s the difference between them. See where are the option

Note: this article is meant primarily for beginners. Obviously ubergeeky readers will already know the difference between power modes.

Sleep Mode

Sleep mode is a power-saving state that is similar to pausing a DVD movie. All actions on the computer are stopped and any open documents and applications are put in memory. You can quickly resume normal, full-power operation within a few seconds. Sleep mode is basically the same thing as “Standby” mode.

The Sleep mode is useful if you want to stop working for a short period of time. The computer doesn’t use much power in Sleep mode.

Hibernate 

The Hibernate mode saves your open documents and running applications to your hard disk and shuts down the computer, which means once your computer is in Hibernate mode, it uses zero power. Once the computer is powered back on, it will resume everything where you left off.

Use this mode if you won’t be using the laptop for an extended period of time, and you don’t want to close your documents.

Hybrid Sleep

The Hybrid Sleep mode is a combination of the Sleep and Hibernate modes meant for desktop computers. It puts any open documents and applications both in memory and on your hard disk, and then puts your computer into a low-power state, allowing you to quickly wake the computer and resume your work. The Hybrid Sleep mode is enabled by default in Windows on desktop computers and disabled on laptops. When enabled, it automatically puts your computer into Hybrid Sleep mode when you put it into Sleep mode.

Hybrid Sleep mode is useful for desktop computers in case of a power outage. When power resumes, Windows can restore your work from the hard disk, if the memory is not accessible.
