Understanding power management
Power management lets you reduce your Notebook power consumption. Your Notebook has two power management modes:

Hibernation is an energy-saving feature and safeguard that saves information to the hard drive, then turns off your Notebook. When you resume from Hibernation, your information returns to the screen where you were previously working. Your Notebook hibernates when the Power button is pressed, when the battery has little power left, or when your Notebook (operating on battery power) is in Sleep mode for more than one hour.
Sleep, also called Standby, is an energy-saving feature that reduces power to system components that are not being used. When Sleep is initiated, your information is saved in Random Access Memory (RAM), and the screen is cleared. Your Notebook is still on, but the display is blank. When you resume from Suspend, your information returns to the screen where you were previously working.

Automatically put your notebook into hibernation
Windows can automatically put your computer into Hibernate mode after a specified period of inactivity. Or Windows can detect when your batteries are running low, and then automatically put your computer in Hibernate mode to save your work before the battery fails.

NOTE: Using Power Options in Control Panel, you can adjust any power management option that your notebook's unique hardware configuration supports. Because these options may vary widely from computer to computer, the options described may differ from what you see. Power Options automatically detects what is available on your computer and shows you only the options that you can control.
To automatically put your computer into hibernation:

In Category view, click Start, click Control Panel, click Performance and Maintenance, and then click Power Options.
In Classic view, click Start, click Control Panel, and then click the Power Options icon.
Click the Hibernate tab, select the Enable hibernate support check box, and then click Apply.
