Charging the main battery
5.375 x 8.375 ver 2.3
❖ Glows green when the main battery is fully charged
❖ Is unlit when the battery is discharged, the battery is not
charging, or the AC adapter is not plugged into the
computer or AC outlet
❖ Flashing amber means the main battery charge is low and
it is time to recharge the main battery or plug in the AC
adapter
If the AC power light flashes amber during charging, either the
battery pack is malfunctioning, or it is not receiving correct
input from the AC power supply.
Disconnect the AC cable and remove the battery pack. See
“Changing the main battery” on page 115 for information on
replacing the main battery.
Charging the main battery
Your computer came with its main battery already installed.
Before using the battery to power the computer, you must
charge the battery.
To charge the main battery, leave the computer plugged into
an AC power source for at least three hours with the computer
turned off. After that, the battery will be completely charged
and ready to power the computer.
TECHNICAL NOTE: The RTC battery does not charge while the
computer is turned off, even when AC power is attached.
The RTC battery charges when the computer is powered on.
For more information about installing or removing the main
battery, see “Changing the main battery” on page 115.
