Power Options:
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. In Sleep mode, any open documents and applications are put in memory while the computer goes into a low-power state. The computer technically stays on, but only uses a smaller of power, and the LED screen will also be off. You can quickly resume normal, full-power operation within a few seconds. Sleep mode is basically the same thing as "Standby" mode. Sleep mode is useful if you want to stop working for a short period of time.
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. Hibernate mode is very similar to sleep, but instead of saving your open documents and running applications to your RAM, it saves them to your hard disk. In other words, Hibernation mode stores the current session on to the hard disk, and resumes the current session when the computer is switched on. This allows your computer to turn off entirely, thus saving power.
Once the computer is powered back on, it will resume everything where you left off. This mode is useful if you don't want to close your documents when you are away for longer periods of time, and would like to continue where you had left off. Hibernate saves an image of your desktop, including all open windows and files. Then it powers down your computer just as if you had turned it off. When you turn your computer on again, your windows and files are open just as you left them.
Stand by: It is a mode the computer, monitor, or other device enters when idle for too long. This mode helps conserve power when a computer or computer device is not in use without having to sacrifice the time it would take to turn off and on the computer. When in Stand by, the computer or monitor has a solid or flashing amber light, indicating that there is still power but the computer is in Standby mode.
When you select Standby, the power to your screen, hard drive, and peripheral devices is cut. However, the power to the computer's memory (RAM) is maintained so your open files stay open. Shutdown basically shuts down your computer completely. If you are going to be away from your computer for an extended time or overnight, putting your system into hibernate mode puts your system into an even deeper sleep than Standby mode and is essentially just short of a complete shutdown.
In Windows 7, the Sleep and Hibernate options are accessed using the arrow button next to the Shut down button on the Start menu.
You can also change the amount of time before your computer goes into sleep or hibernate mode, or turn off each mode completely.
To configure any of the power options, you first have to go to Start, then Control Panel, and then click on Power Options.
