If the RTC battery is low, the real-time clock and calendar may 
display the incorrect time and date, or stop working.

To recharge the RTC battery, plug the computer into a live electrical 
outlet and leave the computer powered on for 24 hours.

It is seldom necessary to charge the RTC battery because it charges 
while the computer is on. If the RTC battery is low, the real-time 
clock and calendar may display the incorrect time and date or stop 
working.

When Hibernation mode is enabled and the RTC battery is 
completely discharged, a warning prompts you to reset the real-time 
clock.

The computer can be used while the RTC battery is being charged, 
although the charging status of the RTC battery cannot be 
monitored.

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 red 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

 for information on 

replacing the main battery.
