





Keep the LCD at the lowest comfortable brightness level. Reducing
brightness even a small amount can significantly reduce power
consumption and increase operating time.

Press Standby to put the computer into standby mode whenever you
are not actively using the computer. Press Standby again to resume
normal operation.

Press Standby after writing to the hard disk to stop the disk rotation.
Then return to operation by pressing Standby again.

Use the Power Savings items in Setup to turn off the LCD when not in
use and to ensure that the hard disk is not powered for longer periods
than necessary.

You can choose between three CPU speeds: high, medium, and low.
The computer uses less power at lower CPU speeds. When using an
application that is not CPU-intensive (for example, many word
processing programs), press Ctrl-Alt-↓↓ to reduce the CPU speed. To
increase the speed again, press Ctrl-Alt-↑↑. This feature is not
available on DX4 models.

You can minimize the number of times the computer needs to access
the hard disk by using disk caches or RAM disks.

2-10

Conserving Battery Power











Disconnect or turn off external options that you are not using.

Use one of the Setup programs to disable ports you are not using.

Use only Texas Instruments options, which are designed to operate
with the least possible energy consumption. Third-party options, such
as RAM and mouse devices, can drain the battery more quickly.

Run the computer with the AC Adapter connected when using external
devices, such as an external keyboard.

Increase the BatteryPro™ power savings to level 4 using the
SETPOWER utility or the Power Level utility in Windows Setup.

Using the Power Utility

AU TravelMate computers have the BatteryPro Power Management utility from
Texas Instruments. To locate the BatteryPro Power Management utility open
the Notebook group in Windows and select Wbattery, Settings, and Options.

Unless you have disabled this utility, it works automatically and transparently
to conserve power while the computer is operating on battery power.

Tips for the Traveler

Your TravelMate Computer is a precision instrument containing many
sensitive components. It should be handled with care. Here are some
suggestions for traveling:



Never expose the computer to excessive vibration.

Do not check the computer as baggage-, take the computer as carry-on
luggage if traveling by air.

Do not put the computer through a security X-ray machine or a metal
detector; have the computer inspected by hand. Be sure the computer
is loaded with a charged battery in case airport security requires you to
turn on the computer.

If you are traveling internationally, carry a proof of purchase with you
in case you need to show it to customs officials.

Avoid placing the computer where it can be stepped on or knocked
around.

Disconnect all peripherals before packing the computer (the Portable
CD-ROM Docking System can stay attached).

Transport the computer with the display closed and the power off.

Cautions:

When packing the computer, do not pack items next to its top cover. Too
much pressure against the top cover can damage the LCD.

Do not travel with a floppy in the floppy drive. This can damage the drive
head.

Changes in temperature and humidity can cause condensation. Allow
the computer to return to room temperature, and inspect the LCD for
condensation before turning on the computer. If the temperature
change is greater than 18° F (10° C), allow the computer to come to
room temperature slowly. If possible, leave the computer for 30
minutes in an environment with a temperature between outside and
room temperatures.

Always carry the computer in a protective case.

Cleaning the Computer

Regularly take the time to check your computer and clean the screen, keyboard,
and case to ensure trouble-free computing.

Caution: Never use alcohol, benzine, thinner, or other strong chemical
agents that could damage the computer's case, and never apply liquid
directly to the computer, only to a clean cloth. Never spray cleaning fluid
or any liquid directly onto the case or screen.

Keep the case of the computer free of dust. Apply a small amount of "Id liquid
cleaner to a dry lint-free cloth, and wipe the case with the cloth.

The surface of the screen is covered with a protective plastic film that may
become smeared and accumulate dust during use. Avoid touching the screen
with your fingers.

Clean the screen regularly by applying a small amount of a diluted neutral
detergent to a dry, lint-free cloth. Gently rub the surface of the screen with the
cloth.
