Using the main battery
To charge the main battery, plug the computer into a live wall
outlet. It takes several hours to charge the main battery with
the computer off. It takes much longer to charge the main
battery while the computer is on. For more information on
battery use, see
“Running the computer on battery power” on
page 110 .
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: When your computer is using all of the
power provided by the AC Adapter to run applications,
features, and devices, the recharging of the battery cannot
occur. Your computer's Power Saver utility can be used to
select a power level setting that reduces the power required for
system operation and allows the battery to recharge.
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.
Battery life and charge time may vary depending on the
applications, power management settings, and features used. NOTE
