3 Getting Started
WARNING! Do not leave the battery pack discharged. The battery pack will discharge
over time. If not using a battery pack, it must continued to be charged every three
months to extend recovery capacity or else it may fail to charge in the future.
NOTE: The battery stops charging if the temperature is too high or the battery voltage
is too high.
Charging the Battery Pack
Before you use your Notebook PC on the road, you will have to charge the battery pack. The battery pack
begins to charge as soon as the Notebook PC is connected to external power using the power adapter.
Fully charge the battery pack before using it for the rst time. A new battery pack must completely charge
before the Notebook PC is disconnected from external power. It takes a few hours to fully charge the
battery when the Notebook PC is turned OFF and may take twice the time when the Notebook PC is
turned ON. The battery charge light turns OFF when the battery pack is charged.
IMPORTANT! If the battery calibration process fails, stop charging and contact an
authorized service center.
Battery Calibration (on selected models)
BIOS provides a battery calibration function. See Appendix for details.
NOTE: If battery calibration is not necessary, this item will not be selectable.
