Battery and Power Management

This chapter describes power management and proper battery operating practices for Presario 1800XL Series Notebooks. These practices include conservation of AC power and extending the operating life of the battery. The following sections also outline proper methods to start and shut down the Notebook in various situations.

Power Modes

Presario 1800XL Series Notebooks have three levels of low power: Hibernation, Standby, and Off.

Hibernation

Hibernation mode 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 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 ª button once.

button once.

To resume from Hibernation mode, press the Power

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 you have finished working has two advantages: 1. It allows the Notebook to wake up faster; 2. It saves more power than the Active-On mode.

CAUTION: 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, click Shut Down, and then select Standby from the options.

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

Full Off

Off mode consumes no power. However, the battery charges while the Notebook is in Off mode if the battery is installed and the Notebook remains plugged into external AC power.

Note: Unsaved information is lost if the Notebook is shut down without saving the data.

To activate Off mode, click the Start button on the Windows taskbar, click Shut Down, and then select Shut down from the options.

button once.

To restart the Notebook from Off mode, press the Power

CAUTION: The Notebook must be in Off mode (completely shut down) when installing or replacing components. Follow the instructions for putting the

Notebook into Off mode, unplug it from the outlet, and remove the battery pack before servicing any parts.
