1-12 Shutting Down the System
Customizing Your Notebook
As with most other computers, your notebook employs a Setup Utility that stores the
basic bootup configuration and power management settings. This chapter describes
how to customize your notebook using the Setup Utility.
Running the Setup Utility
Your notebook has been properly set up and configured prior to delivery. However,
you may find it is necessary to use the notebook’s Setup Utility to change system
configuration information, such as time and date, port assignments, passwords or
power management settings. The Setup Utility can be accessed when “Press <F2> to
enter setup” appears at boot time.
The settings you specify with the Setup Utility are recorded in a special area of
memory called CMOS RAM. This memory is backed up by an independent backup
battery so that it will not be erased when you turn off or reset the system. Whenever
you turn on the power, the system reads the settings stored in CMOS RAM and
compares them to the equipment check conducted during the power-on-self-test
(POST). If an error occurs, an error message is displayed on screen, and you are
prompted to run the Setup Utility.
The Setup Utility consists of four menu pages and the Exit page, as follows:
Main: basic system configuration (time/date, disk drive and memory settings)
Advanced: device interface configuration (I/O ports, sound settings)
Security: password settings
Power: Power management (battery saving settings)
Exit: exit the Setup Utility

type of the new hard disk will automatically be identified when the hard disk is
Boot Sequence Determines where the boot program will look for operating system
files. The default is C: then A:, which checks the hard disk first, and only checks the
floppy disk drive if no system files are found on the hard disk.
Other options for this setting are A: then C:, which check the floppy disk drive (A:)
first, and if no system disk is found in the drive, the system boots from the hard
drive; C: only, which never checks for system files on the floppy disk drive.
Internal Numlock If you are using an external keyboard, you may want to use the
external keyboard’s NumLock key. The NumLock key of the external keyboard also
effects the built-in keyboard, and the built-in keyboard turns on the NumLock status.
To avoid this, set this option to Disabled before using the NumLock key on an
external keyboard.
Key Click Enables or disables audio feedback of key click.
Video Input Determines whether you use the built-in capture board or the ZV port.
System Memory Indicates the size of ‘conventional’ memory to be made available
directly to MS-DOS. It always shows 640 KB.
Extended Memory Indicates the size of extended memory found by the BIOS
during its POST. The value displayed is the amount of memory located above 1MB
in the microprocessor’s memory address map. Because the notebook ships with a
minimum of 16MB of memory as standard, this value will not be less than 15360KB.
The notebook automatically updates the value here when you enter the Setup Utility
after you add an optional memory module.

AC Power
This LED lights green when the notebook is being powered by
AC, and blinks when Suspend to RAM is active using AC power.
The LED is off when the notebook is off or powered by batteries,
or when Suspend to Disk is active.
Battery Power
This LED lights green when the notebook is being powered by
batteries, and blinks when Suspend to RAM is active using
battery power. The LED is off when the notebook is off or
powered by AC, or when Suspend to Disk is active.
Battery Status
During normal operation, this LED stays off as long as the battery
is charged. When the battery charge drops to 20% of capacity, the
LED lights red and a 10-second alarm sounds. When this occurs,
save your work to disk, and connect AC to recharge the battery.
Please note that no alarm sounds if you are using the computer in
the Suspend to RAM mode.
Using Your Notebook 3-1
If the battery is allowed to discharge further during operation,
this LED starts blinking red and a continuous alarm sounds,
indicating a critical battery condition. During Suspend to RAM,
however, the alarm does not sound.
The Suspend to Disk mode activates automatically, and you will
have to connect AC or replace the battery with a charged pack to
resume working.
When AC is connected, this indicator glows green if the battery
pack is fully charged, or orange if the battery is being charged. If
a fault occurs with the battery or charger, this indicator blinks
orange. Try removing the battery pack, then re-installing it. If the
indicator still blinks orange, there may be a problem with the
notebook or the battery pack.
Other Indicator LEDs

3-2 Status Indicator LEDs
Power Sources
The notebook is designed to operate with one of the following power sources:
AC power from a wall outlet
one or two Lithium-ion battery packs
Use AC power whenever possible, relying on the battery pack only when AC power
is unavailable.
Using AC Power
An AC adapter is built into the notebook, to provide power for operation and to
charge the batteries when the AC cord is connected to a wall outlet. The AC input
voltage can range anywhere from 100 to 240 volts, making it suitable for use
virtually anywhere in the world with the appropriate plug adapter. The battery pack
automatically recharges while your notebook is connected to AC. If the notebook is
not powered on, total recharge time for a completely discharged battery is
approximately three hours (or five hours for two packs).
The status indicator LEDs above the keyboard indicate the state of the built-in AC
adapter, as described in the previous section.
The AC power cord provided with the notebook is appropriate for the
voltage of your local area. If you attempt to connect the notebook a wall
outlet other than your local area, check the voltage of the outlet and use
an AC power cord appropriate for the outlet.
Using Your Notebook 3-3
Using Battery Power
The rechargeable lithium-ion battery pack allows you to operate the notebook
without an external power source. When fully charged, a single battery pack can
supply power to your notebook for up to 2 hours; much longer periods of time may
be possible if the notebook’s advanced power management features have been
activated. You can also install a second battery pack in place of the floppy disk drive
or CD-ROM drive, to double the capacity.
The amount of time a battery charge will last will depend on the notebook
usage. Applications which heavily use the peripherals, like the floppy disk
or the CD-ROM drive, will experience shorter power on time.
Low Battery Indication
When your notebook senses that the battery only has enough charge to continue for a
few minutes, it will alert you to a low battery condition by blinking the red battery
status LED and sounding a battery low warning beep. The remaining operating time
depends on the power you are consuming: if you are using the audio system, PC
Card slots, CD-ROM or hard and floppy disk drives, your notebook might run out of
charge very quickly. You should always respond to the battery low indication by
connecting to AC power or turning off your notebook, or suspending your notebook
to disk. If you do not do so, the notebook will automatically suspend to disk
(regardless of the setting of the Suspend Mode option in the Setup Utility) and turn
off. The contents of the memory will be stored in the suspend-to-disk partition. You
will be unable to restart the notebook until you have connected to AC or installed a
fresh, charged battery.
If the notebook is in the Suspend to RAM mode when the battery is
critically low, the notebook will attempt to Suspend to Disk (if enabled in
the Setup Utility), and then turn off.
Charging the Battery
To recharge the battery, connect AC to the notebook as described in the previous
section and turn off the notebook. Approximately three hours are required to fully
charge a low battery(or five hours if two batteries are installed). The Battery Status
Indicator lights in orange while the battery is charging. The indicator flickering in
the recharge may indicate some trouble. Disconnect the notebook, extract the battery
pack, re-insert it, and connect the notebook to AC again. If the indicator still flickers,
the system has a problem.
3-4 Power Sources
• If you have not used the notebook for a long time, the battery may
become completely discharged. In such a case, recharging will take
more time than usual.
• If you use the notebook for a while, the battery will become hot. The
notebook starts recharging after getting back to the normal
Maintaining the Battery Pack
You should discharge the battery pack if you do not use the notebook for a long time
and should recharge it fully before use. If the battery is fully charged and left unused
for a long time.
• The battery will discharge itself slowly, and
The life of the battery will be shortened.
Lithium-ion batteries do not have so-called “memory effect,”and you do
not have to deep discharge the battery pack before charging it.
Disposing of Battery Packs
The capacity of a battery pack is gradually decreasing while used repeatedly.
Although the deterioration rate depends on the operating temperature and
environments, the pack can sufficiently be used for 500 times, after which you
should consider purchasing a replacement battery pack that is identical to the battery
Your local area may have rules which you should follow regarding battery disposal.
In addition to the main lithium-ion battery, you should remember the small backup
battery located under the keyboard. Bring your notebook to a local dealer for
replacement of this backup battery if your notebook begins to lose its time and date
Backup batteries
The notebook has two backup batteries. The rechargeable NiMH battery prevents
loss of data during replacement of the lithium-ion battery while in the suspend mode.
However, this will not work if the battery level of the NiMH battery is low.
Therefore, power-off or suspend to disk is recommended when replacing the lithiumion battery.
The other backup battery is a non-rechargeable coin type Lithium battery for RTC.
Using Your Notebook 3-5
Battery Precautions
Never put the battery pack in a fire, as it could explode and cause injury.
Do not attempt to open or alter the battery pack.
Do not place the battery where it might get hotter than 60°C (140°F).
Do not allow metal objects such as jewelry to short across the battery terminals, as
it could heat up and explode.
The battery includes a circuit breaker to help protect against short circuiting.
However, covering or pressing this breaker switch hard could cause the battery to
Do not allow liquids to come in contact with the battery pack.
Avoid dropping the pack, or other violent shock.
Do not solder to the battery terminals.
Charge the battery pack only with the notebook’s built-in AC adapter.
Do not use the battery pack for any purpose other than powering the notebook
Store the battery pack in a cool and dry place. Never allow the temperature to
exceed 60°C (140°F) during storage.
Recharge the battery pack after storage, before use.

3-10 CD-ROM Drive
Floppy Disk
Floppy disks used by the notebook are made of magnetic material and enclosed in a
protective plastic case. The case protects the magnetic surface of the disk against
scratches, bending and dust. A shutter on the case opens automatically when inserted
into the notebook’s floppy disk drive, exposing the disk to the drive’s read/write
head, which can then retrieve, record or erase data on the disk’s magnetic surface.
When the system attempts to access a floppy disk, the disk starts to spin within its
plastic casing, and the read/write head moves to the proper position on the disk and
performs the operation you requested.

can become stuck in the slot.
3-12 Floppy Disk
Hard Disk Drive
Unlike a floppy disk, a hard disk drive is rigid and completely sealed in a protective,
dust-free environment. A hard disk drive works very much the same as a disk, but it
can retrieve and record data much faster and has a much larger storage capacity.
The notebook is equipped with a removable 2.5-inch integrated drive electronics (or
IDE) hard disk drive. This type of drive embodies the latest in fast, reliable mass
storage by integrating all the control circuitry necessary for operation directly onto
the drive itself. This allows the drive manufacturer to carefully optimize drive
You can also easily replace the hard disk drive, as it is installed in a special
compartment to make it easily removable. Refer to Chapter 4 for details on how to
replace the hard disk drive.
• Make regular backups of your data files from your hard disk to
floppy disks or other media.
• Never try to insert or remove the hard disk while the system is
powered on. Doing so can result in loss of data, and can damage the
system and the hard disk drive’s sensitive circuitry.
• Never turn off or reset the notebook while the HDD indicator LED
above the keyboard is lit.
• When your hard disk drive is removed from the notebook, always store
it in a safe environment free from magnetic fields.

Your notebook features GlidePoint, an integrated pointing device, connected
internally to a PS/2 port and compatible with the Microsoft Mouse and IBM PS/2
mouse. The GlidePoint combines high resolution fingertip control and an ergonomic
design equally suitable for left-handed and right-handed users. Most software
applications will require use of the “left” button.
Figure 3-8. The Integrated GlidePoint
Using the GlidePoint
Take a moment to become familiar with how the GlidePoint works.
Place Your Fingertip
Place your left or right hand next to the GlidePoint, resting your wrist naturally in a
relaxed manner. Place your thumb or forefinger on the GlidePoint.
3-16 GlidePoint
Move Your Fingertip
The rectangular pad of the GlidePoint acts like a miniature duplicate of your display.
As you slide your fingertip across the pad, the pointer on the screen, called the
cursor, moves in the same direction across the screen as your fingertip moves across
the pad. The GlidePoint is very sensitive and you don’t need to exert much pressure
on the pad at all. You’ll get the best results by sliding your fingertip over the pad
very lightly.
Point and Click
When you have placed the cursor over the icon, menu item or command that you
wish to execute, you can press the left button once or twice to execute the command.
This procedure is called “point and click” or “point and double-click”. On the
GlidePoint, you can execute point and clicking even more rapidly. Instead of
clicking by pressing the left button, you can just tap gently anywhere on the
rectangular pad of the GlidePoint. Tap twice rapidly to execute a double-click.
Unlike a traditional pointing device, the whole pad acts as if it were a left button and
each tap on the pad is equivalent to pressing the left button.
If you swap the left and right buttons, “tapping” on the GlidePoint as an
alternative method of pressing the left button will no longer be valid.
Drag and Drop
You can execute commands or move files by using “drag and drop”. In drag and
drop, you activate a file by pointing to it and clicking. However, when you click the
button, you do not release the button but instead hold it down. You can then drag the
active file around the screen by moving your finger around the pad. When you have
placed the file where you want it, for example in a new directory, release the left
button. The file will drop into the new location. You can also do drag and drop
operations using the GlidePoint as a large left button. Position the cursor over the
item that you want to drag. Gently tap twice on the pad. On the second tap, keep
your finger in contact with the pad. You can then drag the selected object around the
screen by moving your fingertip across the pad. When you lift your fingertip from
the pad, the selected object will drop into place.

Appendix C: Troubleshooting
This appendix provides information on pinpointing and solving common problems
that you may encounter using the notebook.
Problems with your notebook can be caused by something as minor as an unplugged
power cord or as major as a damaged hard disk drive. The information in this
appendix is designed to help you find and solve minor problems. If you still have a
problem after trying all the suggested remedies in this appendix contact your dealer.
The problems that you might encounter can be divided into two basic categories:
hardware and software. Hardware problems can be further divided into being of an
electrical or a mechanical nature. You will know you have a hardware problem if, for
example, the screen is blank, the notebook cannot recognize the disk drives, or you
get an error message during the Power-On Self Test (POST).
Software problems can occur at several levels. Both your operating system and your
software application programs are capable of generating errors and error messages.
If you encounter a software error, try to determine if the error message is from your
operating system or from an application program, and refer to the appropriate
manual for possible remedies.
You can also refer to the Windows 95 manual or Windows Help program to solve
the problem. To access the Help program, click the Start button, then point to Help.
It also gives you Troubleshooting tips and Index.
Common Problems
Successful troubleshooting is the result of careful observation, deductive reasoning,
and an organized approach to solving the problem. If you encounter a problem,
begin by performing a careful visual inspection. Check the exterior of the notebook
first. If no lights are displayed, check the battery charge or power outlet, the plug and
power cord, and any power switches that may affect your notebook. If the notebook
has been connected to any peripheral devices, look for loose or disconnected cables.
You may also need to check the fuses and breakers in your electric box.
A few common problems and suggested solutions are presented in the examples
which follow.
Question: Why doesn’t the power switch function?
The power switch does not accept just a light touch. Depress the switch firmly.

The card may be attempting to use COM3 or COM4 ports in a manner that
conflicts with the COM1 or COM2 port being used by another device. You may
be able to resolve the conflict by running the Setup Utility to change the COM
port settings. If your PC Card uses COM3, set the COM1 Port: setting to
Disabled. If your PC Card uses COM4, set the COM2 Port: setting to Disabled or
IR Type: setting to Disabled.
Question: Why can’t I use an SRAM or Flash card?
To use an SRAM or Flash card, you need to enable the card drivers. Remove
“REM” from the following lines of CONFIG.SYS file, using Windows Notepad,
then save the file and reboot.

Question: Why can’t I produce sound?
Confirm the sound driver is installed. From the Windows Control Panel, click
System, Device Manger tab, then Sound, video and game controllers. Verify the
Audio Driver is installed. If not, install the driver from the Add New Hardware
applet in the Control Panel.
Check the Windows volume control and mute button. Click the speaker symbol
beside the clock on the taskbar to open the Volume Control window.
Is the Volume control on the right side of the notebook turned down?
Question: Why does the communication software not function?

management. In the Windows Control Panel, double-click the Power icon, and
set Power management to Off. After using the communication software, set Power
management back to Advanced or Standard.
The POST Error Messages
The notebook performs the Power-On Self Test (POST) every time you turn on or
reset the system. The POST is a series of system checks that verifies the correct
operation of your notebook’s hardware.
If the POST detects a critical error (e.g., a system board failure), the notebook will
halt and generate an audible alarm. If a failure is detected in an area other than the
system board (such as the keyboard), a non-critical error message is displayed on the
screen and testing is stopped. You can continue testing when a non-critical error
occurs by pressing the F1 key.
When the POST encounters an error that requires you to correct something, either a
beep code will sound or a message will be displayed in a box in the middle of the
screen. If you need to enter the Setup Utility to correct a problem, press F2.
Otherwise, press F1 to continue the boot process and ignore the error.
