How to use the battery efficiently
There are a number of factors which affect the
lifetime of the battery. These include:
Use of Power Management. Refer to the Power
Management section later in this chapter for
further details.
The type of work you do with your computer.
For example, excessive saving of large files to disk
tends to draw a relatively large amount of power.
System configuration.
There are many aspects of system configuration
which have direct affect on the lifetime of the
battery. For example, disabling the sound or the
serial and parallel ports can help to conserve
battery power.
If the battery is not going to be used for a long period
of time, it should be run down to a low charge,
removed from the computer, and stored in a place
which is not subject to high levels of humidity, within
the temperature range 0-40
C.
Ensure a good connection to the battery is maintained
by keeping both terminals of the battery clean and dry.
If the parallel or serial port are not being used, disable
them in Setup, as this will conserve some power.
Refer to Chapter 7, BIOS setup for further details.
The system should be used within the temperature
range 10-35
C at all times.
If the battery is running out
Whenever using the computer with the battery pack,
you should check the battery-level frequently. You can
do this by checking the Windows battery meter, as
described in the previous section.
You can also have visible and audible warnings which
come into operation when the battery is low on
charge. The visible warnings come into operation
automatically, but the audible warnings can be
enabled and disabled in Setup. For details on setting
this function, refer to the Power Management section
later in this chapter and the Setup utility.
These low-power warnings are comprised of two
distinct stages, as described in the following table.
