Running the computer on battery power
5.375 x 8.375 ver 2.3.2
To ensure that the battery maintains its maximum capacity,
operate the computer on battery power at least once a month
until the battery is fully discharged. Please see
for procedures. If the computer is
continuously operated on AC power, either through an AC
adapter or a docking station (if applicable to your system), for
an extended period (more than a month), the battery may fail
to retain a charge. This may shorten the life of the battery, and
the battery light may not indicate a low-battery condition.
For optimum DVD performance, it is recommended that you
play DVDs while running the computer on AC power. In
addition, your computer’s Power Saver utility can be used to
select a power level setting for DVD playback.
The computer also has an internal real-time-clock (RTC)
battery.
The RTC battery powers the RTC memory that stores your
system configuration settings and the current time and date
information. It maintains this information for up to a month
while the computer is turned off.
TECHNICAL NOTE: The RTC battery does not charge while the
computer is turned off, even when AC power is attached.
The RTC battery charges only while the computer is powered on.
