The Battery Power System
A fully charged pack will provide approximately 1.6 to 2.0 hours of
battery life. The battery life can be extended by using the power
management features.
Before using the computer on battery power for the first time, check
the battery status icon on the Windows Toolbar to make sure the
battery is fully charged. See
Battery Status later in this section for a
description and explanation of the Windows Battery icon.
Charging the battery takes about 2.5 hours for the Ni-MH battery
pack. The Li-Ion battery pack takes about 4 hours to charge when the
system is in off state. If possible, always charge the battery
completely.
Removing the Battery Pack
To remove the battery pack from its compartment, please refer to
Chapter Two,
Inserting and Removing the Battery Pack .
Preparing the Battery Pack for Use
Before using the battery pack for the first time, the Smart Battery IC
within the battery pack should be calibrated in order to get accurate
reporting of remaining battery life status. To calibrate the battery
pack follows the instructions below:
1
Insert the battery into the battery compartment and turn on the
Notebook. If the battery is completely without power go to the
next step. Otherwise, let the battery run down until the battery
low-low warning beeps are heard. The system will automatically
enter Suspend mode.
2
Turn the Notebook off. Connect the AC adapter and let the
battery fully recharge. When the battery charge indicator turns
off, the battery is fully charged.
3 The battery pack is now calibrated properly.
