115 Mobile Computing Running the computer on battery power Running the computer on battery power The computer contains a removable Lithium-Ion (Li-ion) battery pack that provides power when you are away from an AC outlet. This is the main battery. You can recharge it many times. Battery Notice Battery life may vary, depending on applications, power management settings, and features utilized. Recharge time varies depending on usage. The battery may not charge while the computer is consuming full power. 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 your accessories information that shipped with your computer, or to stay current on the most recent software and hardware options for your computer, and for other product information, regularly check the Toshiba Web site at accessories.toshiba.com. 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 "Charging the batteries" on page 116 for procedures. If the computer is continuously operated on AC power, either through an AC adapter or docking station for an extended period, more than a month, the battery may fail to retain a charge. It may not function efficiently over the expected life of the battery and the battery light may not indicate a low-battery condition. NOTE For optimum DVD performance, Toshiba recommends that you play DVDs while running on AC power rather than on battery power.
