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 31 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 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 
(
) 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).
