 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, follow 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. Turn On the notebook, let the battery run down until the battery is in low-low state and you
hear a warning beeps. The system will automatically enter the Suspend mode. You can
now connect the AC adapter.
4. The battery pack is now calibrated properly.
In general, using the battery until the low-low battery-warning indicator appears and fully
recharges the battery each time (full discharge/charge cycle) will ensure the accurate reporting of
the battery gauge status.
 Automatic Battery Pack Charging Function
You can automatically charge the battery pack by using the AC Adapter. The charge time is
about three hours when the Notebook power is turned off. The following table summarizes the
charging modes:
Charge Mode Charge Time
Fast 3 hours with the system off or in Suspend mode. The temperature must
be 25°C or below room temperature.
Pre-Charge A pre-charge is supplied to the Li-Ion battery pack.
 Battery Status
Windows XP has an applet in the Control Panel that will display an icon in the Windows taskbar
indicating when the Notebook is running on battery power or is attached to the AC adapter.
This applet also displays a meter that indicates how much charge is remaining in the battery.
