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-

face.
• 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

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

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.
