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:
•
Processing speed
•
HDD auto off
•
LCD Brightness
See Chapter 7,
Setup and Password Security
.
How often and how long you use the hard disk 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 (Suspend/Standby) mode conserves battery power
if you are frequently turning the computer off and on.
Enabling Hibernation mode conserves battery power more effectively
than Resume (Suspend/Standby) mode, if you leave the computer off
for longer intervals. Resume mode requires battery power to maintain
data in memory, but Hibernation mode does not. However, Resume
mode is faster and requires less power to startup when you turn on the
computer.
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
When you turn off your computer with fully charged batteries, the batteries
retain data for the following approximate time periods:
Battery pack
4 to 5 days
RTC battery
1 month
