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.

Charging the RTC battery

Your computer has an internal real-time clock (RTC) battery.
The RTC battery powers the System Time Clock and BIOS
memory used to store your computer's configuration settings.
When fully charged, it maintains this information for up to a
month when the computer is powered off.
TECHNICAL NOTE: The battery does not charge while the
computer is consuming full power.
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.
