Compaq nw9440 - Mobile Workstation Manual page 33

A battery pack inserted in the computer charges whenever the
computer is plugged into external power through an AC adapter,
an optional docking device, or an optional power adapter.
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 more information about determining the amount of charge in
a battery pack, refer to the
pack."
