Monitoring main battery power
The computer can be used while the RTC battery is being charged,
although the charging status of the RTC battery cannot be
monitored.
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 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
If the AC power light flashes amber during charging, either a battery
pack is malfunctioning, or it is not receiving correct input from the
AC power supply.
Disconnect the AC power cord/cable and remove the battery pack.
See “Changing the main battery” on page 126 for information on
replacing the main battery.
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).
