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
ª
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.
Ä
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.
