[. . . ] 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. With repeated discharges and recharges, the battery's capacity will gradually decrease. Therefore, an often used, older battery will not operate for as long as a new battery even when both are fully charged. In this case, the Power Saver utility will indicate a 100% charge for both the old and new battery, but the displayed estimated time remaining will be shorter for the older battery. Maximising 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 Saver, to conserve battery power. This mode has the following options: · Processor speed (Processing Speed) · Turn off monitor (Display Auto Off) · Turn off hard disks (HDD Auto Off) · System standby (System Auto Off) · Monitor brightness (LCD brightness) How often and how long you use the hard disk, DVD-ROM and the diskette drive. How you use optional devices, such as a PC card, to which the battery supplies power. Make sure the battery terminals stay clean by wiping them with a clean dry cloth before installing the battery pack.
