Low-Power Modes
Compaq Presario 1600XL Series Notebook Computers have two levels of low-power
management: Hibernation and Standby.
Hibernation
Hibernation helps conserve battery life and protect data. The Notebook automatically
enters Hibernation mode when the battery has little power left or when the Notebook
(operating on battery power) is in Standby mode for more than one hour. As the Notebook
enters Hibernation, it automatically stores the contents of its memory to the hard drive
before it shuts down. When the Notebook comes out of Hibernation, it returns to its
former state.
Activate Hibernation mode by pressing the Power button once.
To restart the Notebook, press the Power button once. When the Notebook enters or
wakes from Hibernation mode, a Progress window is displayed on the screen.
Standby
Standby is a low-power mode, also referred to as Sleep mode. Selecting Standby mode
instead of turning off the Notebook when finished has two advantages: 1. It enables the
Notebook to wake up faster than if it had been turned off completely; 2. It saves more
power than the active (On) mode.
Activate Sleep mode by pressing Fn+F4. Or click Start, select the Shut Down option, and
click Standby.
Д Д Д Д CAUTION: The Notebook maintains system information and open files while in
Standby mode. However, unsaved information is lost if the Notebook is turned off
prior to system wake-up, or if a power loss occurs while using the AC adapter.
