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.

ÄCAUTION: 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.
