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 to conserve battery power. This mode has the following options: ■ Display auto off ■ Hard Disk Drive auto off ■ System auto off ■ LCD brightness ■ How often and how long you use the hard disk, optical media drive and the disk drive (if one is connected). ■ 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 Sleep Mode or Hibernation Mode conserves battery power if you are frequently turning the computer off and on. ■ Where you store your programs and data. ■ Closing the display 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. 6-10 Satellite M100
