Anleitung Zusammenfassung


NOTE Battery charge time may vary depending on the applications, power management settings, and features used. Mobile Computing 105 Charging batteries Charging the main battery To charge the main battery while it is in your computer, plug the computer into a live electrical outlet. The battery charges whether the computer is on or off. TECHNICAL NOTE: The recharging of the battery cannot occur when your computer is using all of the power provided by the AC adaptor to run applications, features, and devices. Your computer's Power Options utility can be used to select a power level setting that reduces the power required for system operation and will allow the battery to recharge. The battery may not start charging immediately under the following conditions: . The battery is extremely hot or cold. To ensure that the battery charges to its full capacity, wait until it reaches room temperature (50 to 80 degrees Fahrenheit, 10 to 26 degrees Celsius). . The battery is almost completely discharged. Leave the power connected and the battery should begin charging after a few minutes. HINT: Once the battery is fully charged, we recommend that you operate your computer on battery power until the battery discharges completely. Doing this extends battery life and helps ensure accurate monitoring of battery capacity. Charging the RTC battery Your computer has an internal real-time clock (RTC) battery. The RTC battery powers the System Time Clock and BIOS memory used to store your computer’s configuration settings. When fully charged, it maintains this information for up to a month when the computer is powered off. The RTC battery may have become completely discharged while your computer was shipped, resulting in the following error message during startup: BAD RTC BATTERY BAD CHECKSUM (CMOS) CHECK SYSTEM Mobile Computing 106 Monitoring main battery power NOTE The above error message may vary by computer model. The RTC battery does not charge while the computer is turned off even when the AC adaptor is charging the computer. The RTC battery charges when the computer is powered on. 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 the computer into a live electrical outlet and leave the computer powered on for 24 hours. NOTE 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 main battery power The computer’s main battery light gives you an indication of the main battery’s current charge. The following also applies to the secondary battery (available on certain models) if installed. . Glows amber while the main battery is being charged (AC adaptor connected). . Glows blue when the main battery is fully charged. . Is unlit when the battery has discharged, the battery is not charging, or the AC adaptor is not plugged into the computer or AC outlet. NOTE Battery life and charge time may vary, depending upon power management settings, applications and features used. . Flashes amber when the main battery charge is low and it is time to recharge the main battery or plug in the AC adaptor. Mobile Computing 107 Monitoring main battery power NOTE If the AC power light flashes amber during charging, either a battery pack is malfunctioning, or it is not receiving correct input from the AC power supply. Disconnect the AC power cord/cable and remove the battery pack. See “Changing the main battery” on page 112 for information on replacing the main battery. HINT: Be careful not to confuse the battery light ( ), the on/off light ( ), and the power button light (to the left side of the keyboard). When the on/off light or power button light flashes amber, it indicates that the system is suspended (using the Windows® operating system Sleep command).

The computer needs this time to check the battery’s remaining capacity and perform its calculations. 1 Highlight the power icon in the Notification Area. A pop-up message displays the remaining battery power as a percentage. With repeated discharges and recharges, the battery’s capacity gradually decreases. A frequently used older battery does...
