The lights on the recharger indicate the following:
m
Yellow
The battery is charging.
m
Green
The battery is fully charged.
m
Red
The recharger does not recognize the type of battery you inserted. If
you are charging a replacement battery, follow the instructions that came
with it.
m
No light
Either the recharger is not plugged in, the other battery is being
charged (if you have two batteries in the recharger), or the battery is
defective. (If the light goes off during recharging, there is a problem with
the battery.)
Recharging in both the computer and a recharger
You can use a single power adapter to run the PowerBook and the battery
recharger at the same time.
If the PowerBook is on and contains a battery that is not fully charged, the
computer charges the internal battery first. The external battery does not
begin charging until the internal battery is fully charged. It takes a little over
2 hours for a fully depleted battery to charge.
If the PowerBook is in sleep or is shut down, internal and external batteries
charge simultaneously. If both batteries are fully depleted, it takes about
4.5 hours to charge both. If the internal battery is fully charged or absent, the
external battery takes a little over 2 hours to charge.
