106 Mobile Computing Monitoring main 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 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 blue 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. NOTE Battery life and charge time may vary, depending upon power management settings, applications and features used.
