Mobile computing
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.
TECHNICAL NOTE: Depending on your system, the RTC battery may
only charge while the computer is turned on.
Monitoring main battery power
The computer’s main battery light gives you an indication of the
main battery’s current charge. The following also applies to the
secondary battery (available on certain models) if installed.
❖
Glows amber while the main battery is being charged
(AC adaptor connected)
❖
Glows white when the main battery is fully charged
❖
Is unlit when the battery has discharged, the battery is not
charging, or the AC adaptor is not plugged into the computer or
AC outlet
Battery life and charge time may vary, depending upon power
management settings, applications and features used.
❖
Flashes amber when the main battery charge is low and it is
time to recharge the main battery or plug in the AC adaptor
HINT: Be careful not to confuse the battery light
(
)
, the ON/OFF
light
(
)
, and the power button light (near the upper left corner of
the keyboard).
When the ON/OFF light or power button light flashes amber, it
indicates that the system is suspended (using the Windows
®
operating system Sleep command).
TECHNICAL NOTE: The recharging of the battery cannot occur when
your computer is using all of the power provided by the AC adaptor
to run applications, features, and devices. Your computer's Power
Options 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.
