[. . . ] When the on/off light flashes amber, it indicates that the system is suspended (using Windows® XP Standby command). Charging the RTC battery The computer contains an internal battery that provides power for the real-time clock (RTC) and calendar. 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. Mobile Computing Monitoring battery power 125 If the RTC battery is low, the real-time clock and calendar may display the incorrect time and date, or stop working. To recharge the RTC battery, plug in the computer and leave it turned on until the RTC battery is fully charged. The RTC battery does not charge while the computer is turned off even when AC power is attached. 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 126 Mobile Computing Monitoring battery power 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. 1 2 3 Click Start, then click Control Panel. The TOSHIBA Power Saver Properties window appears.

[. . . ] The RJ11 connector is a 6wire connector. 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. [. . . ]
