Charging the battery
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.
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.
Charging the RTC battery
The computer contains an internal battery that provides
power for the real-time clock (RTC) and calendar.
During normal use, the main battery keeps the RTC battery
adequately charged. Occasionally, the RTC battery may lose
its charge completely, especially if you have had the
computer turned off for a long time.
TECHNICAL NOTE: The RTC battery does not charge while the
computer is turned off even when AC power is attached.
If the RTC battery is low, the real-time clock and calendar
may display the incorrect time and date, or stop working.
