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:
How often and how long you use the hard disk, CD-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.
Retaining data with power off (standby mode)
When you turn off your computer with fully charged batteries, the
computer will retain data for the following approximate time periods:
Battery pack

Satellite 1130 Series
Display auto off
HDD auto off
System auto off
