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.
Monitoring main battery power
The computer's main battery light gives you an indication of
the main battery's current charge:
Glows amber while the main battery is being charged
(AC adaptor connected)
Glows green 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
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: 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.
Battery life and charge time may vary, depending upon power
management settings, applications and features used.
HINT: Be careful not to confuse the battery light

When the on/off light flashes amber, it indicates that the
system is suspended (using the Windows
Standby 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
Saver 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.
