The battery may not start charging immediately under the follow-
ing conditions:
❖
The battery is extremely hot or cold. To ensure that the battery
charges to its full capacity, wait until it reaches room tempera-
ture (50 to 80 degrees Fahrenheit, 10 to 30 degrees Celsius).
❖
The battery is almost completely discharged. Leave the power
connected and the battery should begin charging after a few
minutes.
Once a battery pack is fully charged, we recommend that you
operate your computer on battery power until the battery pack
discharges completely. Doing this extends battery life and
helps to ensure accurate monitoring of battery capacity.
You can purchase an optional battery charger that charges up to
two batteries at the same time. See “Charging More than One Bat-
tery at a Time” on page 138 for more information about the battery
charger.
In normal use, the main battery keeps the other batteries ade-
quately charged. Occasionally, the backup and RTC batteries may
lose their charge completely, especially if you’ve had the com-
puter turned off for a long time. To recharge the backup battery,
connect the AC adapter to the computer and plug it into a power
socket. Leave the computer turned on for 30 hours, or turned off
for 40 hours.
