Battery and Power Management

This chapter describes power management and proper battery operating practices for Presario 1400 Series Notebooks. These practices include conservation of AC power and effective control of energy to extend the operating life of the battery. The following Power Mode sections also outline the correct methods of starting and shutting down the Notebook in various situations.

Power Modes

Presario 1400 Series Notebooks have three levels of low power: Hibernation, Standby, and Full 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 shutdown. When the Notebook wakes from Hibernation, it returns to its former state.

Note: When the Notebook enters or wakes from Hibernation mode, a Progress window is displayed.

To activate Hibernation mode, press the Power Ÿ button once.

To resume from Hibernation mode, press the Power Ÿ button once.

Standby

Standby is a low-power mode, also referred to as Sleep mode. The Notebook maintains system information and open files while in Standby mode. Selecting Standby instead of turning off the Notebook when your have finished working has two advantages: 1. It allows the Notebook to wake up faster than it would if it had been turned off; 2. It saves more power than the Active-On mode.

ÄCAUTION: 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.

To activate Standby/Sleep mode, press Fn+F4 or click Start. Select the Shut Down option, and then Standby.

To resume from Stand/Sleep mode, press any key.
