Power and Power-Up Modes 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 TOSHIBA Power Saver, to conserve battery power. This mode has the following options: ■ CPU Processing 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 and the floppy disk drive. ■ How much charge the battery contained to begin with. ■ How you use optional devices, such as a PC card, to which the battery supplies power. ■ Enabling Standby mode conserves battery power if you are frequently turning the computer off and on. ■ Where you store your programs and data. ■ Closing the LCD display panel when you are not using the keyboard saves power. ■ Operating time decreases at low temperatures. ■ The condition of the battery terminals. Make sure the battery terminals stay clean by wiping them with a clean dry cloth before installing the battery pack.
