[. . . ] During normal use, the main battery keeps the RTC battery adequately charged. Occasionally, the RTC battery may lose its charge completely, especially if you have had the computer turned off for a long time. TECHNICAL NOTE: The RTC battery does not charge while the computer is turned off even when AC power is attached. 118 Mobile Computing Monitoring battery power If the RTC battery is low, the real-time clock and calendar may display the incorrect time and date, or stop working. It is seldom necessary to charge the RTC battery because it charges while the computer is on. If the RTC battery is low, the real-time clock and calendar may display the incorrect time and date or stop working. When Hibernation mode is enabled and the RTC battery is completely discharged, a warning prompts you to reset the real-time clock. The computer can be used while the RTC battery is being charged, although the charging status of the RTC battery cannot be monitored. Monitoring battery power The battery light indicates the battery's current charge. The indicator light: Glows green when the battery is fully charged Glows amber while the battery is being charged Does not glow if the external power source is disconnected or if the battery is completely discharged Determining remaining battery power 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. Mobile Computing Monitoring battery power 119 1 2 Click Start, Control Panel, then Performance and Maintenance. Double-click the Toshiba Power Management icon. The current power source and battery power remaining section displays the current charge state of the battery. The value displays as a percentage of remaining battery charge. 3 Click the Battery Power Meter tab. Sample Toshiba Power Management Battery Power Meter tab 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. 120 Mobile Computing Monitoring battery power Conserving battery power How long a fully charged battery lasts when you are using the computer depends on a number of factors, such as: How the computer is configured How much you use the display panel instead of an external monitor How much you use the hard disk and other drives Whether you use any optional devices to which the battery supplies power, such as a PC Card Where you are working--since operating time decreases at low temperatures Toshiba's power-saving options greatly increase the length of time you can use the computer before it becomes necessary to recharge the battery. Toshiba has combined these options into preset power usage modes. What to do when the battery runs low When the battery runs low you can: Connect the computer to an external power source and recharge the battery. Put the computer in Hibernate mode and replace the battery with a charged spare. Save your work and turn off the computer. If you do not manage to do any of these things before the battery completely runs out of power, the computer automatically enters Hibernate mode and turns itself off. Hibernate mode keeps track of where you were so, when you turn on the power again, you can continue where you left off. Mobile Computing Monitoring battery power 121 The computer stores the information on what you were doing until the battery runs out of power. If you have Hibernate mode enabled (the default), the computer copies the details of your open programs and files to the hard disk before shutting down. Setting battery alarms Your computer can be configured to warn you when the battery is running low. Each alarm can be set to alert you when a specified percentage of remaining battery power haw been reached. You can set how the warning occurs: sound an alarm, display a message, both, or none. You can also set the computer to enter Standby mode or Hibernate mode or to completely power down when the alarm goes off. To set an alarm: 1 2 3 Click Start, Control Panel, then Performance and Maintenance. [. . . ] RJ-45 -- A connector used to attach computers to LANS (local area networks) and to link ISDN (Integrated Services Digital Network) devices to NT-1 (Network Terminator devices). ROM (read-only memory) -- Non-volatile memory that can be read but not written to. By non-volatile, we mean that information in ROM remains whether or not the computer is receiving power. This type of memory is used to store your computer's BIOS, which is essential instructions the computer reads when you start it up. [. . . ]
