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.
