Charging a Battery Pack

To prolong battery life and optimize the accuracy of battery charge displays:

■If you are charging a new battery pack:

❏Charge the battery pack while the notebook is connected to external power through the AC adapter.

❏When you charge the battery pack, charge it fully.

■If you are charging an in-usebattery pack:

❏Allow the battery pack to discharge to about 10 percent of a full charge through normal use before charging it.

❏When you charge the battery pack, charge it fully.

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 “Monitoring the Charge in a Battery Pack” in this chapter.
