periodically. Please see "Maintaining your battery" on page 49 for
procedures. If the computer is continuously operated on AC power,
either through an AC adaptor or a port replicator (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 may cause the battery meter to be inaccurate.
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.

AC outlet
❖ Flashes amber when the main battery charge is low and it is
time to recharge the main battery or plug in the AC adaptor
TECHNICAL NOTE: Depending on your system, the RTC battery may
only charge while the computer is turned on.
Battery life and charge time may vary, depending upon power
management settings, applications and features used.
