1-10
Power Saving Modes
0V Suspend Mode
0V Suspend mode saves the exact spot you are
at on your computer, then removes all power
without losing any data.
In 0V Suspend mode, the computer saves the
current computer state onto your hard disk
drive then shuts off. When you turn the
computer on again, it restores the computer to
the saved state within about a minute.
Press the 0V Suspend hot key (Fn+F2) to enter
0V Suspend mode. To resume normal operation,
press the power switch. 0V Suspend mode
occurs automatically if the 0 VOLT SUSPEND
TIMEOUT parameter in Setup is enabled and
times out or if the BATTERY LOW SUSPEND option is
enabled and your battery runs down to a
critically low level.
Note: Your computer will not enter 0V Suspend
mode if the 0V Suspend file is missing or is the
incorrect size. Refer to Chapter 2, Adding Memory
section for further information.
5V Suspend Mode
5V Suspend mode consumes very little power
when you are not using your computer, yet still
resumes quickly. With a fully charged battery,
your computer can remain in 5V Suspend mode
for days.
1-11
Power Saving Modes
Caution: If your computer loses power while
!
in 5V Suspend, you will lose all of your
unsaved data.
In 5V Suspend mode, the computer saves the
current computer state into your system
memory then shuts off power to most of the
devices except the system memory. The standby
indicator flashes to indicate the computer is in
5V Suspend mode. When the computer resumes
from 5V Suspend mode, it restores the computer
to the saved state.
Press the 5V Suspend hot key (Fn+F3) or close
the display cover to enter 5V Suspend mode.
The computer also enters 5V Suspend mode if
the 5V SUSPEND TIMEOUT parameter in Setup is
enabled and times out.
1-12
To resume normal operation, press any key on
the internal keyboard or press the power switch.
The computer also resumes from 5V suspend if
the RESUME ON MODEM RING or RESUME ON ALARM
options are enabled in the System Setup and a
modem ring or alarm occurs.
Note: It takes the computer a few seconds to
resume from a 5V Suspend. You may see the
screen blank a few times while the computer
restores all of the system states.
Power Saving Modes
Standby Mode
Standby mode saves some computer power by
turning off a few of the unused devices and still
allows you to resume your work instantly. The
standby indicator lights up in Standby mode.
Press the Standby hot key (Fn+F4) to enter
Standby mode. The computer also enters
Standby mode if the STANDBY TIMEOUT parameter
in Setup is enabled and times out.
To resume from Standby mode, press any key or
touch the touchpad. The computer also
resumes from Standby if the RESUME ON MODEM
RING or RESUME ON ALARM options are enabled in
the System Setup and a modem ring or alarm
occurs.
Note: The computer acts on the key you press.
To prevent unintended results, press a nonprinting character such as Shift, Ctrl or Alt.
Refer to Chapter 3, Responding to Low Battery
Conditions section, for more ideas on how to
conserve power.

Guidelines for Battery Use
Caution: Never dispose of exhausted batteries
!
in a fire. Recycle if possible.
The battery should be handled carefully to
ensure maximum life. In particular:
q Do not drop the battery or subject it to
shocks.
q Do not expose the battery to direct sunlight,
moisture, chemicals, or temperature
extremes.
q Do not short the battery leads or insert the
battery upside down.
3-2
q Charge the battery after several days of
disuse to keep it fully charged. If your
computer is idle for an extended period of
time, charge the battery every 3 months.
q Never use the battery to power other
products.
q The battery pack has thermal fuses to
prevent unsafe computer operation. The
computer may not operate on battery power
after storage in a very warm place until the
thermal fuses cool.
Guidelines for Battery Use
q Keep the Duracell smart battery properly
calibrated to maintain a maximum charge
by following the conditioning instructions in
this chapter.
q This computer is designed to only work with
the Smart Duracell battery packs. Only use
the authorized DR35 and DR201 packs with
this computer.
Note: The Texas Instruments Extensa 670 are
designed to use a Duracell DR35 or DR201
Rechargeable Battery. Texas Instruments
participates in the Duracell pro.link program. If
you would like to purchase additional batteries,
please call the Authorized Duracell Purchase
Hotline at 1-800-603-8225. If you have questions
about battery performance, recycling a used
battery, or any other battery-related question,
please call Duracell Consumer Relations at 1-800551-2355 (9:00 AM - 5:00 PM EST).
3-3
Switching to Battery Power
To use battery power, install batteries as
described in Installing the Battery Pack later in
this section.
As long as the battery has a charge remaining,
you can switch to battery power by removing the
connection to the AC adapter, even if the
computer is already on.
Your computer switches back to AC power when
an AC adapter is plugged into the computer,
even if the computer is already on.
To maintain a full charge on your battery,
always reconnect the computer to the AC
adapter whenever possible.
3-4
Responding to
Low Battery Conditions
There are two battery low stages in this
computer. When the battery capacity reaches
7% capacity (about 10 minutes remaining), the
computer enters the first stage of battery-low
warning. At this time the battery low LED found
on the LCD panel flashes and an audible
warning sounds. You can keep the battery
audible warning from ever sounding by disabling
the BATTERY LOW WARNING BEEP option in Setup.
When the battery capacity reaches 4% capacity
(about 2 minutes remaining), a second audible
warning sounds. If the BATTERY LOW SUSPEND
option is enabled in Setup, the computer enters
0V Suspend mode if there is no system activity
or if the AC is not plugged in.
The following actions can maximize the time
before the battery is depleted and minimize the
effect of losing power:
q Set the screen brightness and contrast
control to the lowest possible setting.
q Save your work in progress to minimize the
danger of losing data.
q If you are using a RAM disk, save the
contents of the RAM disk to the hard disk
drive.
3-5
Responding to
Low Battery Conditions
q Whenever you are not actively using the
computer, press the 5V Suspend hot key
(Fn+F3) or Standby hot key (Fn+F4) to put
the computer into 5V Suspend mode or
Standby mode respectively.
q Turn off the computer or put the computer
in 0V Suspend mode (Fn+F2) if it does not
need to be active. The computer does not
consume power in 0V Suspend mode.
Once your computer enters 0V Suspend mode,
you can install a fully-charged battery and then
resume from 0V Suspend mode. AC power can
be connected at anytime.
3-6

most circumstances:
1. Install the battery pack into your computer (if
not already installed).
2. Connect the AC adapter.
To maintain a full charge, leave the computer
connected to the AC adapter except when
transporting the computer.
The computer charges the battery when it is on
as well as when it is off, as long as the AC is
plugged in.
3-7
Calibrating the Battery
This Extensa system uses either a Duracell
Nickel-Metal-Hydride (NiMH) DR35 or LithiumIon (Li-Ion) DR201 rechargeable battery. Your
new Duracell smart batteries keep extremely
accurate track of the battery capacity. However,
all rechargeable batteries lose capacity over time
due to different charging and discharging
conditions, as well as general wear and usage.
In order to keep accurate track of the true
capacity, the battery must be calibrated every
once in awhile.
Caution: If the battery loses track of the true
capacity, it will not correctly predict low
!
battery conditions and can cause the system
to shut off prematurely and without warning.
The battery itself keeps track of when it needs to
be calibrated. The computer will post a warning
when you boot up the system when it is time to
re-calibrate. To calibrate the battery, you must
first fully charge the battery, then fully discharge
the battery.
Use the following instructions to calibrate your
battery.
1. Charge the battery by leaving the battery in
the computer and having the AC adapter
plugged into the computer. The battery is
fully charged when the charging LED turns
off.
2. Disconnect the AC adapter from the
computer.

Your computer can execute almost all programs
written to execute on AT computers. When
installing software, you may need to provide the
following information to the installation
program:
Display The 11.3-inch or 12.1-inch display has
an 800 x 600 (SVGA) resolution. When
installing an application, select the
highest resolution configuration that
both the program and the computer can
support. If you are using the computer
with a high-resolution external monitor,
you can select resolutions up to 1280 x
1024 depending on the model of your
monitor.
5-4
If you select a resolution larger than that
supported by your display, you can still
view the display by panning the screen.
Keyboard The computer keyboard emulates all
functions of an IBM AT-101 enhanced
keyboard. When installing an
application, select the IBM 101 or AT
enhanced keyboard configuration.
Guidelines for Installing
Applications
Mouse If you are using the built-in pointing
device or an external PS/2 mouse, you
may select the Microsoft® or Standard
PS/2 port mouse.
You can also select Synaptics PS/2
touchpad for the built-in pointing device.
Configuring the Computer for
the Software
Some programs require you to modify the way
the computer operates to ensure compatibility.
Memory Your computer comes with 16 MB of
memory. This is sufficient to run most
software. For improved operation, you
may want to install additional memory
(refer to Chapter 2 and Chapter 4 for
information on upgrading your memory).
5-5
Using System Passwords
The computer has a two-password security
system — Supervisor and User.
The Supervisor password is used by system
administrators who manage multiple notebooks
and gives an extra level of security while still
allowing users to set their individual Setup
preferences in the system Setup menu. If only
one password is set, the Supervisor password is
also the User password.
If both the Supervisor password and the User
password are set, the Supervisor password must
be entered to gain access to the Setup Security
options: SUPERVISOR PASSWORD, DISKETTE ACCESS,
AND FIXED DISK BOOT SECTOR.
5-6
Both passwords prevent unauthorized access to
the computer at system startup or when the
computer resumes from 0V Suspend mode if the
PASSWORD CHECK DURING RESUME parameter in
Setup is enabled.
Using System Passwords
Setting a System Password
Caution: If you forget the system password,
you will not be able to use your computer. To

5. Enter the new password (up to seven
printable text characters) and press Enter,
then retype the password for verification and
press Enter.
6. The password becomes active after you save
the changes and exit Setup.
5-7
Using System Passwords
If you set a password, you are prompted for the
new password before starting your computer or
entering Setup.

Disconnecting from the Desktop
Follow these steps to disconnect your computer
from external accessories.
1. Save your work in progress.
2. Shut down the operating system.
3. Turn off the computer.
4. Disconnect the cord from the AC adapter.
5. Disconnect the keyboard, pointing device,
printer, external monitor, and other external
devices.
If your external devices are connected to the
optional port replicator, disconnect the
notebook from the port replicator. You do not
need to disconnect the external devices from
the port replicator.
6-2
6. Disconnect the Kensington lock if you are
using one to secure the computer.
Moving Around
Preparing the Computer
Before moving the computer, press Fn+F3 to
place it in 5V Suspend mode. After placing the
computer in 5V Suspend mode, close and latch
the cover. You can now safely take the computer
anywhere you go within the building.
To bring the computer out of 5V Suspend mode,
press a key or touch the touchpad.
What To Bring to Short Meetings
A fully charged battery runs the computer for 23 hours under most circumstances. If your
meeting is shorter than that, you probably do
not need to bring anything with you other than
the computer.
What To Bring to Long Meetings
If your meeting will last longer than 3 hours or if
your battery is not fully charged, you may want
to bring the AC adapter with you to plug in your
computer in the meeting room.
If the meeting room does not have an electrical
outlet, reduce the drain on the battery by
putting the computer in 5V Suspend mode
(Fn+F3) or Standby mode (Fn+F4) whenever you
are not actively using the computer.
6-3
Taking the Computer Home
Preparing the Computer
After disconnecting the computer from your
desktop, follow these steps to prepare the
computer for the trip home.
1. Remove all media from the drives. Failure to
remove the media can damage the drive head.
2. Pack the computer in a protective case that
can prevent the computer from sliding around
and cushion it if it should fall.
Caution: Avoid packing items next to the top
!
cover of the computer. Pressure against the
top cover can damage the screen

car to avoid exposing the computer to
excessive heat.
q Changes in temperature and humidity can
cause condensation. Allow the computer to
return to room temperature, and inspect the
screen 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
temperature.

Taking the Computer Home
Setting Up a Home Office
If you frequently work on your computer at
home, it may be worthwhile purchasing a second
AC adapter for use at home. With a second AC
adapter, you can avoid transporting the extra
weight to and from home.
If you use your computer at home for significant
periods of time, you might also want to add an
external keyboard, monitor, or mouse.
