Conserving Battery Power
With a little care, you can maximize the time that your TravelMate 3000 will operate on a
single battery charge. The following tips will help you run your computer for the longest
possible time on battery power.
q Keep the illumination of the LCD screen at the lowest comfortable
brightness level. Reducing brightness even a small amount can
significantly reduce power consumption.
q Use the Power Saving category items on the Setup Program to ensure
that the LCD screen is not powered when not in use, and the hard disk is
not powered for long periods when it is not being accessed. However,
bear in mind that if the HDD Motor Off period is too short, this will
increase hard disk access time because the drive motor takes several
seconds to power up before disk accesses can occur.
q You can choose between three CPU speeds: 20 MHz, 10 MHz and 8
MHz. The lower the CPU speed, the less power the computer uses.
When using an application program that is not CPU-intensive, (for
instance, many word processing programs) set the CPU speed to the
lowest setting on the Setup Program.
q The fewer options that are connected to the computer, the lower the
power consumption. Note, however, that printers and external monitors
do not get their power from the TravelMate 3000, and so have no effect
on power consumption. However, some external options, such as
keyboards, use power from the internal battery pack, so run the
TravelMate 3000 with the AC Adapter connected when using external
devices that use power.
q Refer to your BatteryPro & Productivity Software User's Manual for
more information on conserving battery power.
