80 Mobile Computing Charging batteries 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: Depending on your system, the RTC battery may only charge while the computer is turned on. Power management Your computer ships with the power management options preset to a configuration that will provide the most stable operating environment and optimum system performance for both AC power and battery modes. Changes to these settings may result in system performance or stability issues. Users who are not completely familiar with the power management component of the system should use the preset configuration. For assistance with setup changes, contact Toshiba's Customer Support Center. Charging batteries The battery needs to be charged before you can use it to power the computer. Always use the AC adaptor specified by Toshiba. You can order a Toshiba AC adaptor from Toshiba's Web site at accessories.toshiba.com. NOTE Battery charge time may vary depending on the applications, power management settings, and features used. To charge the main battery, plug the computer into a live electrical outlet. The battery charges whether the computer is on or off.
