To ensure that the battery maintains its maximum capacity, operate 
the computer on battery power at least once a month. The Lithium-
Ion battery has no memory effect so it is not necessary to let the 
battery fully discharge each time. However, for better accuracy of 
the battery meter, it is helpful to fully discharge the battery 
periodically. Please see “Maintaining your battery” on page 46 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.
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.
❖ 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
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 
(
)
 with the 
ON/OFF light 
(
)
When the ON/OFF light flashes amber, it indicates that the system is 
suspended (using the Windows
®
 operating system Sleep command).
