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 to conserve battery power. This mode has the following options:
• System Auto Off
• Display Auto Off
• LCD Brightness
• Cooling Performance
• CPU Speed
• CPU Sleep Mode
See Chapter 7, TSETUP and Passwords .
„ How often and how long you use the hard disk, CD-ROM, DVD-ROM
and the diskette 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 Resume 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.
