36 Mobile computing After a period of time, the battery will lose its ability to perform at maximum capacity and will need to be replaced. This is normal for all batteries. To purchase a new battery pack, see the accessories information that shipped with your computer or visit the Toshiba Web site at accessories.toshiba.com. Use only batteries designed to work with your Toshiba notebook computer. To ensure that the battery maintains its maximum capacity, operate the computer on battery power at least once a month. The LithiumIon battery has no memory effect so it is not necessary to let the battery fully discharge each time. However, for better accuracy of the battery meter, it is helpful to fully discharge the battery periodically. Please see "Maintaining your battery" on page 40 for procedures. If the computer is continuously operated on AC power, either through an AC adaptor or a port replicator (if applicable to your system), for an extended period (more than a month), the battery may fail to retain a charge. This may shorten the life of the battery, and may cause the battery meter to be inaccurate. The computer also has an internal real-time-clock (RTC) battery. The RTC battery powers the RTC memory that stores your system configuration settings and the current time and date information. It maintains this information for up to a month while the computer is turned off. TECHNICAL NOTE: The RTC battery does not charge while the computer is turned off, even when AC power is attached. The RTC battery charges only while the computer is powered on. 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 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 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
