[. . . ] The computer needs this time to check the battery's remaining capacity and to calculate the remaining operating time, based on the current power consumption rate and remaining battery capacity. The actual remaining operating time may differ slightly from the calculated time. Maximizing battery operating time A battery's usefulness depends on how long it can supply power on a single charge. How long the charge lasts in a battery depends on: How you configure the computer (for example, whether you enable battery-power saving options). The computer provides a battery save mode, which can be set in Power Options, to conserve battery power. This mode has the following options: CPU Precessing speed Screen brightness Cooling Method System Standby System hibernation Monitor Power off HDD Power off How often and how long you use the hard disk, optical disc drive and the diskette drive. Enabling hibernation and Standby mode conserves battery power if you are frequently turning the computer off and on. Make sure the battery terminals stay clean by wiping them with a clean dry cloth before installing the battery pack. Retaining data with power off When you turn off your computer with fully charged battery, the battery retain data for the following approximate time periods. User's Manual 6-7 NB 100 Series Retention Time Battery type Battery pack (4 cell) RTC battery State and Retention Time about 3 hours (standby mode) about 14 days (shutdown mode) about 3 months Extending battery life To maximize the life of your battery packs: At least once a month, disconnect the computer from a power source and operate it on battery power until the battery pack fully discharges. If the battery pack has at least five minutes of operating time, continue operating until the battery pack is fully discharged. If the battery LED flashes or there is some other warning to indicate a low battery, go to step 4. Connect the AC adaptor to the computer and the power cord to a power outlet. The Battery LED should glow blinking green slow to indicate that the battery pack is being charged. If you will not be using the system for an extended period more than one month, remove the battery pack. If you are not going to use the computer for more than eight hours, disconnect the AC adaptor. Store spare battery packs in a cool dry place out of direct sunlight. Replacing the battery pack When the battery pack reaches the end of its operating life you will need to install a new one. If the Battery indicator flashes green shortly after fully recharging the battery, the battery pack needs to be replaced. You might also replace a discharged battery pack with a charged spare when you are operating your computer away from an AC power source. This section explains how to remove and install battery packs. 6-8 User's Manual Power and Power-up Modes Removing the battery pack To remove a discharged battery, follow the steps as detailed below: When handling battery pack, be careful not to short circuit the terminals. Also do not drop, hit or otherwise apply impact; do not scratch or break the casing and do not twist or bend the battery pack. Do not remove the battery pack while the computer is in Standby mode. Data is stored in RAM, so if the computer loses power it will be lose. In hibernation mode, data will be lose if you remove the battery or disconnect the AC adaptor before the save is completed. Wait for the Disk indicator, optical disc drive indicator and external device indicator to go out.
