Battery packs

Power 7–5

A battery pack inserted in the computer charges whether the

computer is off or in use, but the battery pack charges faster while

the computer is off. Charging may be delayed 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:

■ On: the battery pack is charging.

■ Blinking: the battery pack has reached a low-battery

condition and is not charging.

■ Blinking rapidly: the battery pack has reached a critical

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 the “

Monitoring the battery pack charge”

section next in this chapter.

Monitoring the battery pack charge

This section explains several ways to determine the amount of

charge in a battery pack.

Obtaining accurate charge information

To increase the accuracy of all battery charge indicators:

■ Allow a battery pack to discharge to about 10 percent of a full

charge through normal use before charging it.

■ When you charge a battery pack, charge it fully.

✎

The charge even in a new battery pack may be reported

inaccurately until the battery pack has been fully charged

at least once.

■ If a battery pack has been unused for one month or more,

calibrate the battery pack instead of simply charging it. For

calibration instructions, refer to “

Calibrating a battery pack.”
