124 Mobile Computing Running the computer on battery power Battery Notice To ensure that the battery maintains its maximum capacity, operate the computer on battery power at least once a month until the battery is fully discharged. Please see "Maximizing battery life" on page 132 for procedures. If the computer is continuously operated on AC power, either through an AC adapter or a docking station (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 the battery light may not indicate a low-battery condition. In addition to the main battery, you may also have a second battery installed in the Slim SelectBay. If you travel and need to work for many hours without an AC power source, you may purchase a battery module for use in the computer's Slim SelectBay, or carry additional charged battery packs with you. 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 main battery light ( ) glows amber while the battery is being charged, and glows green when it is fully charged. The battery may not start charging immediately under the following conditions:
