These practices include conservation of AC power and extending the operating life of the battery. The following sections also outline the proper methods for starting and shuting down the Notebook in different situations. Power Modes Compaq Presario 1700 Series Notebook Computers have three levels of low-power management: Hibernation, Standby, and Off. Hibernation Hibernation mode helps conserve battery life and protect data. The Notebook automatically enters Hibernation 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 ª button once. To restart the Notebook, press the Power ª button once. When the Notebook enters or wakes from Hibernation mode, a Progress window is displayed on the screen. Standby Standby mode 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 allows the Notebook to wake up more quickly 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.

Battery and Power Management
This chapter describes power management and proper battery operating practices for
Presario 1700XL Series Notebooks. These practices include conservation of AC power and
extending the operating life of the battery. The following sections also outline the proper

management:
Hibernation, Standby

Hibernation
Hibernation
mode helps conserve battery life and protect data. The Notebook automatically
enters Hibernation 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.
