80 Mobile Computing Charging batteries ❖ The main battery is almost completely discharged. Leave the power connected and the main battery should begin charging after a few minutes. HINT: Once the main battery is fully charged, we recommend you operate your computer on battery power until the main battery discharges completely. Doing this extends the life of the main battery and helps ensure accurate monitoring of battery capacity. Charging the RTC battery The RTC battery provides power for the internal real-time clock and calendar. During normal use, the main battery keeps the RTC battery adequately charged. Occasionally, the RTC battery may lose its charge completely, especially if you have had the computer turned off for a long time. To recharge the RTC battery, plug in the computer and leave it turned off for at least 48 hours. TECHNICAL 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 become slow or stop working. When Hibernation mode is enabled and the RTC battery is completely discharged, a warning prompts you to reset the realtime clock. Using a battery charger You can purchase an optional battery charger that recharges Lithium Ion Polymer (Li-Ion Polymer) battery packs without requiring the use of your computer.
