Safety Instructions

Use the following safety guidelines to help protect yourself and
your notebook.

When Using Your W451U Notebook Computer

CAUTION: Do not operate your portable computer for an
extended period of time with the base resting directly on
your body. With extended operation, heat can build up in
the base.

Allowing sustained contact with the skin can cause discom-

fort or a burn.

• Do not attempt to service the notebook yourself. Always follow in­stallation instructions closely.

• Do not carry a battery in your pocket, purse, or other container
where metal objects (such as car keys) could short-circuit the bat­tery terminals. The resulting excessive current flow can generate
extremely high temperature and may cause burns to your skin.

• Be sure that nothing rests on your AC adapter’s power cable and
that the cable is not located where it can be tripped over or stepped
on.

• While you are using the computer or charging the battery, place
the AC adapter in a ventilated area, like on a desktop or on the
floor. Do not cover the AC adapter with papers or other items that
may prevent ventilation. Also, do not use the AC adapter while it is
inside a carrying case.

• Do not insert objects into the air vent of your notebook computer.
Doing so can cause short-circuiting and may result in fire or electri-

cal shock.

• Use only the AC adapter and batteries that are supplied by your
notebook manufacturer. Using other types of battery or AC adapter
may heighten the risk of fire or explosion.

• Incorrectly placed batteries may result in an explosion.

• Replace only with the same or compatible battery recommended
by the manufacturer.

• Please discard used batteries according to the manufacturer’s in­structions.

• Before you connect your notebook to a power source, ensure that
the voltage rating of the AC adapter matches that of the available
power source.

- 115 V/60 Hz in most of North and South America and some Far

Eastern countries such as South Korea and Taiwan.

- 100 V/50 Hz in eastern Japan and 100 V/60Hz in western Japan.

- 230 V/50 Hz in most of Europe, the Middle East, and the Far

East.

• If you use an extension cord with your AC adapter, ensure that the

total ampere rating of all devices plugged into the extension cord

does not exceed its total capacity.

• When removing battery from your notebook, first turn off the sys­tem, disconnect the AC adapter from the electrical outlet, then re­move the battery.

• To avoid risk of an electrical shock, do not connect or discon­nect any cables, or perform maintenance or reconfiguration of this
product during a thunderstorm.

• Do not throw batteries into fire, doing so may cause explosion.
Check with local authorities first for battery disposal instructions.

• When setting up your notebook for work, place it on a level sur-

• When traveling, do not check your notebook as baggage. You can
put your notebook through an X-ray security machine, but never
put your notebook through a metal detector. If you have your note­book checked by hand, be sure to have a charged battery ready in
case you are asked to turn on your notebook.

• When traveling with the hard drive removed from your notebook,
wrap the drive in an insulated material, such as cloth or paper. If
you have the drive checked by hand, you may be asked to install
the drive into your notebook. Your can have the hard drive checked
through an X-ray machine, but never put the drive through a metal
detector.

• When traveling, do not place your notebook in the overhead stor­age compartment where it could shift around. Do not drop your
notebook or subject it to other mechanical shocks.

• Protect your notebook, battery, and hard drive from environmental
hazards such as dirt, dust, food, liquids, extreme temperature, and
direct exposure to sunlight.

• When you move your notebook in environments where there is a
substantial difference of temperature or humidity level, condensa­tion may form on or within your notebook. To avoid damaging your
notebook, please allow sufficient time for the moisture to evaporate
before continue using.

NOTICE: When taking your notebook from a colder to a warmer environ-

ment or vice versa, allow your notebook enough time to adapt to the

new environment before turning on power.

•When unplugging the power cord, please make sure that you pull
on its connector or on its strain relief loop, and not on the power

cord itself. As you pull out the connector, please ensure that it is
pulled out evenly in order not to bend its connecting pins. Also, be­fore you connect the power cord, make sure that both connectors
are correctly oriented and aligned.

• Before you clean your notebook, turn it off first, unplug it from its

W451U NOTEBOOK USER’S MANUAL

2.1 Using the Battery Pack

W451U notebook computer is designed to operate with one of the
following power sources:

• AC power
(using the AC adapter connected to an electrical outlet)

• Lithium-Ion (Li-Ion) battery pack

You should use the AC adapter whenever possible; use the battery
pack only when AC power is unavailable. The rechargeable Li-Ion
battery pack allows you to operate your notebook computer without
an external power source. When you use the AC adapter to con

­nect your notebook to a power outlet, the internal battery will begin
to recharge. While the battery is charging, the Battery Charge icon
on the indicator panel will be on. Once the battery is fully charged,
the Battery Charge icon will turn off. Quick charging time is 2.5
hours for the Lithium-Ion (Li-Ion) battery when the computer is
turned off, while the normal battery charging time is 3.5 hours.

• Operating a fax modem, video, or audio equipment can increase
the use of your computer’s power.

• Decreasing monitor brightness can also save power.

• When the battery is not fully charged, allow your battery to be
charged completely before using it (i.e., before disconnecting AC
power). Calibrating the battery before use is also highly recom

­mended.

• Li-Ion Battery is vulnerable, do not charge it with other power

adapter, otherwise fire or explosion may occur.

►Replacing the Battery◄
The battery will gradually weaken over time. We recommend that
you replace your battery when you notice a significant decrease of
battery capacity.
To change the battery pack, follow the steps below:

1. Turn off the computer.

2. Close the lid and flip the computer over.

3. Slide the side battery latch (1) to the left. Continue to hold it until
the battery is removed.

4. Make sure the replacement battery is properly oriented before
inserting it into the battery compartment.

►Maintenance of the AC Adapter◄

• Do not connect the adapter to any other device.

• Do not step on the power cord or place heavy objects on top of

it. Carefully route the power cord and keep cables away from all
traffic.

• When unplugging the power cord, do not pull on the cord itself but

on the plug instead.

• If you are using an extension cord, make sure that the devices

plugged onto the cord do not exceed its total capacity. Further

­more, the devices plugged into the electrical outlet shall not ex­ceed the fuse’s total ampere rating .

• Please verify power voltage before connecting the electrical cord
to the power outlet. If you are uncertain of its power specifica

­tion, please consult with your local vendors or power company for
more details.

Operating Basics

98

2.2 Connecting the AC Adapter

The AC adapter converts AC power to DC power and reduces the
voltage supplied to the computer. It can automatically adjust to any
voltage from 100 to 240 volts and outputs power at 19 volts, 3.42A,
allowing you to use your notebook computer in almost any region.

CAUTION: Use only the AC adapter and the power cord we recom­mend. Using the wrong adapter may damage your computer. We
assume no responsibilities for damages arising from misuse of AC
adapters.

To properly connect the adapter, follow the steps as below:

1. Connect the power cord to the AC adapter.

2. Connect the AC adapter to the DC power port on the right of
your computer.

3. Connect the AC adapter power cord to an AC outlet.

2.3 Turning Your Notebook On and Off

►Turning on the power◄
Open the notebook lid, press and hold the power button for one or
two seconds. The power indicator will glow blue once the computer
is powered on.

►Turning off the power◄
If you are not going to use your notebook computer for a while, it
is best to turn off its power. Before turning off power, close all pro­grams first and shut down the operating system

After turning off your notebook computer, make it a habit to leave
the LCD panel open for a while after it has been used for an ex­tended period of time. This allows the interior of your notebook
computer to cool off. Closing the panel will force the heat up
against the LCD screen, and doing so after a while may damage
the screen. More importantly, never close the LCD panel for a long
period of time when the computer is on or when the power saving
function is disabled.

►Suspend mode◄
You can adjust default power management settings in the Power
Option/Advanced dialog box. The Power Options dialog box pro­vides several operating functions after your computer has been idle
for a while.

• Percentage of recovery completed

• Time elapsed

• Estimated time remaining

The time it takes FirstWare Recover Pro to complete the recovery
process ranges from 15 minutes to an hour, depending on the size
of the recovery image. The more applications and utilities that were
included in the factory setup, the longer the process will take.

• Amount of data (in Kilobytes) to be recovered

Cancel—If you select Cancel, the recovery process will stop, yet
the system will become unbootable. It is recommended that you se­lect Cancel only when you plan to delay the recovery process.

►Successful Recovery◄
When the recovery process is successfully completed, the following
situations will take place automatically:

• The progress screen will disappear once the FirstWare Recov­er progress reaches 100%.

• The computer will reboot.

• Operating system will start, and desktop will appear.

The start-up of the operating system indicates success of the recov­ery process.

The operating system should now be working, and factory-installed
applications should now be available and functional. However your
personal files are no longer available

W451U NOTEBOOK USER’S MANUAL

5.1 Frequently Asked Questions



My computer swtiches to hibernation mode much too quickly,
and I have to constantly hit a key or move the mouse to bring
back the screen. What can I do?

This is part of Windows Power Management. Access Power
Management by clicking on Start / Control Panel / Performance
and Maintenance / Power Options, and change the time next
to the “Turn off monitor” option to the time you want. You have
the choice of either adjusting time for the power supply or for
the battery.



I’ve heard that cleaning and rearranging files on the hard drive
will improve program’s launch speed, how do I do this?

Good disk maintenances can improve program launch speed.
This normally includes deleting unnecessary files, and de

­fragmenting hard disk so that files can be more efficiently
grouped. Windows contains maintenance utilities for these
tasks; run Disk Cleanup to remove unnecessary files, and Disk
Defragmenter to defragment fragmented file blocks. For more
information about these utilities, please refer to your Windows
documentation.



The dial tone volume of the internal fax/modem is too low. How
can I increase its volume?

Go to Start/Control Panel/Sounds, Speech, and Audio Devices,

under Device volume, adjust your speaker volume by control

-

ling the volume bar.



What kind of external microphone can I use with my notebook

computer?

You will need to use a self-amplifying microphone.



There are echoes coming from my speakers. What can I do?

Double click on the Speaker icon on the task bar. Then, under
Microphone Balance, check the Mute box.



Because of a software problem, I was unable to shut the
computer down from Windows, I pressed the power button to
power off the computer, but it didn’t work. How can I force a
power off?

Make sure you press the power button for at least 4 seconds.
Normally, this will force the computer to shut off.



Why can’t I charge the battery of my portable computer after it

was out of use for some time?

After your portable computer has not been used for a long
time (say: more than one month), the battery will enter into low
voltage protection mode. Under this circumstance, restoring to
normal voltage will require the battery to be slowly charged for
several hours. Once the battery has been fully charged, your

3534

computer will resume to normal operation.



My computer says: “CMOS Battery Low”, what should I do?

If your computer is without power (i.e. unplug the computer
power source from the power outlet and remove the battery
pack from it) for over 45 days, you would lose the information
stored in CMOS.
Please follow the steps below to reconfigure your CMOS set­tings:

1. Press F2 to enter into the BIOS setup utility.

2. Select “Load Optional Defaults?”. When you see the follow­ing prompt, choose <OK> and then press <Enter>.

3. Select “Save Changes and Exit”, select <OK> and press
<Enter> to restart your computer.



How to unplug or eject devices

1.In the notification area next to your task bar, double-click the
Safe Removal icon. Safe removal displays a list of Plug and
Play devices that support safe removal and that are currently
attached to the system.

If you do not see the Safe Removal icon, your device does not

support safe removal, and you cannot unplug or eject your de­vice using Safe Removal.

2.In Safely Remove Hardware, in the list of devices, select the
device that you want to unplug or eject, and then click Stop.
This tells the system that you will be unplugging or ejecting the

device.

3.In Stop a Hardware device, click OK.
A notification appears stating that it is now safe to unplug or
eject the device.

Caution
Unplugging or ejecting a device that supports safe removal

without first using the Safe Removal application to warn the
system can cause data to be lost or your system to become
unstable. For example, if a device is unplugged during a data
transfer, data loss is likely. If you use Safe Removal, however,
you can warn the system before you unplug or eject a device,
preventing possible loss of data.

Note
For removable storage devices that can safely be removed

while the system is on, the system disables write caching by
default. It does this so the devices can be removed without
loss of data. When write caching is disable, however, the
system wll likely experience slower performance, so be sure
to enable write caching when you have finished removing the
device.
