88 Mobile Computing Monitoring battery power NOTE 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. Monitoring 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 red when the main battery is fully charged NOTE 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 NOTE 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 93 for information on replacing the main battery.
