Monitoring The Battery Pack Charge; Obtaining Accurate Charge Information - HP dv8000 - 403809-001 Notebook Laptop Keyboard Manual

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
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.
✎
■
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
Power
The charge even in a new battery pack may be reported
inaccurately until the battery pack has been fully charged
at least once.
