Charging the main battery

The computer’s main battery light gives you an indication of

the main battery’s current charge:

❖ Glows amber while the main battery is being charged

(AC adaptor connected)

❖ Glows green when the main battery is fully charged

❖ Is unlit when the main battery has discharged, the battery

is not charging, or the AC adaptor is not plugged into the

computer or AC outlet

❖ Flashes amber when the main battery charge is low and it

is time to recharge the main battery or plug in the AC

adaptor

If the AC power light flashes amber during charging, either the main

battery is malfunctioning, or it is not receiving correct input from the

AC power supply.

Disconnect the AC power cord/cable and remove the main battery

pack. See “Changing the main battery” on page 129 for information

on replacing the main battery.

Charging the main battery

Before using the battery to power the computer, you must charge

the battery.

To charge the battery, leave the computer plugged into an AC power

source with the computer turned off until the battery light glows

green. After that, the battery will be completely charged and ready

to power the computer.

Once the battery is charged for the first time, avoid leaving the

computer plugged in and turned off for more than a few hours at a

time. Continuing to charge a fully charged battery can damage the

battery.

TECHNICAL NOTE: The recharging of the battery cannot occur when

your computer is using all of the power provided by the AC adaptor

to run applications, features, and devices. Your computer’s Power

Options utility can be used to select a power level setting that

reduces the power required for system operation and will allow the

battery to recharge.

Battery life and charge time may vary depending on the applications,

power management settings, and features used.
