Learning the Basics Toshiba's online resources 127 Toshiba's online resources Toshiba maintains a number of online sites to which you can connect. These sites provide information about Toshiba products, give help with technical questions and keep you up to date with future upgrades. For more information, see "Contacting Toshiba" on page 224. Chapter 4 Mobile Computing This chapter covers all the aspects of using your computer on battery power. Toshiba's energy-saver design Your computer enters a low-power, Standby mode when it is not being used, thereby conserving energy and saving money in the process. It has a number of other features that enhance its energy efficiency. Many of these energy-saving features have been set by Toshiba. We recommend you leave these features active, allowing your computer to operate at its maximum energy efficiency, so that you can use it for longer periods of time while traveling. For more information on managing your power usage, see "PC Diagnostic Tool" on page 178. 128 Mobile Computing Running the computer on battery power 129 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. You can recharge it many times. 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 138 for procedures for doing this. 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 lowbattery condition. When the on/off light flashes amber, it indicates that the system is suspended (using Windows® XP Standby command). Displaying remaining battery power NOTE Wait at least 16 seconds after turning on the computer before trying to monitor the remaining battery power. The computer needs this time to check the battery's remaining capacity and perform its calculations. You can monitor the battery's remaining charge. The computer calculates the remaining battery charge as it operates, based on your current rate of power use. To show remaining power: 1 2 Click Start, then Control Panel, and then Performance and Maintenance. In the Control Panel window, double-click the TOSHIBA Power Saver icon. Mobile Computing Running the computer on battery power 133 The TOSHIBA Power Saver Properties dialog box appears. Sample TOSHIBA Power Saver Properties Dialog Box The estimated battery life remaining is indicated on the top right-hand side of the Power Save application window. With repeated discharges and recharges, the battery's capacity will gradually decrease. A frequently used older battery will not power the computer for as long as a new battery, even when both are fully charged. TECHNICAL NOTE: The computer drains the battery faster at low temperatures. Check your remaining charge frequently if you are working in temperatures below 50 degrees Fahrenheit. The computer calculates the remaining battery charge based on your current rate of power use and other factors such as the age of the battery. 134 Mobile Computing What to do when the battery alarm sounds The Windows operating system has additional power management options that can be accessed through an icon in the Control Panel. For more information, see "PC Diagnostic Tool" on page 178. What to do when the battery alarm sounds Your computer can be configured to warn you of a low battery charge condition so you can take the necessary steps to save your work.
