Charging a Battery Pack

To prolong battery life and optimize the accuracy of battery
charge displays:
If you are charging a new battery pack:
If you are charging an in-use battery pack:
A battery pack inserted in the notebook charges whenever the
notebook is connected to external power through an AC adapter
or through an optional docking device or an optional automobile
or aircraft adapter.
A battery pack inserted in the notebook charges whether the
notebook is off or in use, but the battery pack charges faster while
the notebook is off. Charging may take longer if a battery pack is
new, has been unused for 2 weeks or more, or is much warmer or
cooler than room temperature.
The battery light displays charge status as follows:
On: The battery pack is charging.
Blinking: The battery pack has reached a low-battery
condition and is not charging.
Off: The battery pack is fully charged or not installed.
For information about determining the amount of charge in a
battery pack, refer to
