Charging the main battery

To charge the battery, plug the computer into a live wall
outlet. It takes several hours to charge the battery with the
computer off. It takes much longer to charge the battery while
the computer is on.
The battery may not start charging immediately if:
❖
The battery is extremely hot or cold.
To ensure that the battery charges to its full capacity, wait
until it reaches room temperature (50 to 80 degrees
Fahrenheit, 10 to 26 degrees Celsius).
❖
The battery is almost completely discharged.
Leave the power connected, and the battery should begin
charging after a few minutes.
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 will allow the battery to recharge.
HINT: Once the battery is fully charged, we recommend that
you operate your computer on battery power until the battery
discharges completely. Doing this extends battery life and
helps ensure accurate monitoring of battery capacity.
