Preface

Instructions for Care and Operation

The notebook computer is quite rugged, but it can be damaged. To prevent this, follow these suggestions:

1. Don’t drop it, or expose it to shock. If the computer falls, the case and the components could be dam-

aged.

2. Keep it dry, and don’t overheat it. Keep the computer and power supply away from any kind of heating

element. This is an electrical appliance. If water or any other liquid gets into it, the computer could be

badly damaged.

Do not expose the computer

to any shock or vibration.

Do not place it on an unstable

surface.

Do not place anything heavy

on the computer.

Do not expose it to excessive

heat or direct sunlight.

Do not leave it in a place

where foreign matter or mois-

ture may affect the system.

Don’t use or store the com-

puter in a humid environment.

Do not place the computer on

any surface that will block the

Vents/Fan Intakes.

Preface

3. Avoid interference. Keep the computer away from high capacity transformers, electric motors, and other

strong magnetic fields. These can hinder proper performance and damage your data.

4. Follow the proper working procedures for the computer. Shut the computer down properly and don’t

forget to save your work. Remember to periodically save your data as data may be lost if the battery is

depleted.

5. Take care when using peripheral devices.

Do not turn off the power

until you properly shut down

all programs.

Do not turn off any peripheral

devices when the computer is

on.

Do not disassemble the com-

puter by yourself.

Perform routine maintenance

on your computer.

Use only approved brands of

peripherals.

Unplug the power cord before

attaching peripheral devices.

Preface

Power Safety

The computer has specific power requirements:

• Only use a power adapter approved for use with this computer.

• Your AC/DC adapter may be designed for international travel but it still requires a

steady, uninterrupted power supply. If you are unsure of your local power specifi-

cations, consult your service representative or local power company.

• The power adapter may have either a 2-prong or a 3-prong grounded plug. The

third prong is an important safety feature; do not defeat its purpose. If you do not

have access to a compatible outlet, have a qualified electrician install one.

• When you want to unplug the power cord, be sure to disconnect it by the plug head,

not by its wire.

• Make sure the socket and any extension cord(s) you use can support the total cur-

rent load of all the connected devices.

• Before cleaning the computer, make sure it is disconnected from any external

power supplies (i.e. AC/DC adapter or car adapter).

Do not plug in the power

cord if you are wet.

Do not use the power cord if

it is broken.

Do not place heavy objects

on the power cord.



Power Safety

Warning

Before you undertake

any upgrade proce-

dures, make sure that

you have turned off the

power, and discon-

nected all peripherals

and cables (including

telephone lines). It is

advisable to also re-

move your battery in

order to prevent acci-

dentally turning the

machine on.

Preface

Battery Precautions

• Only use batteries designed for this computer. The wrong battery type may explode, leak or damage the com-

puter.

• Do not remove any batteries from the computer while it is powered on.

• Do not continue to use a battery that has been dropped, or that appears damaged (e.g. bent or twisted) in any

way. Even if the computer continues to work with a damaged battery in place, it may cause circuit damage,

which may possibly result in fire.

• Recharge the batteries using the notebook’s system. Incorrect recharging may make the battery explode.

• Do not try to repair a battery pack. Refer any battery pack repair or replacement to your service representative

or qualified service personnel.

• Keep children away from, and promptly dispose of a damaged battery. Always dispose of batteries carefully.

Batteries may explode or leak if exposed to fire, or improperly handled or discarded.

• Keep the battery away from metal appliances.

• Affix tape to the battery contacts before disposing of the battery.

• Do not touch the battery contacts with your hands or metal objects.



Battery Disposal & Caution

The product that you have purchased contains a rechargeable battery. The battery is recyclable. At the end of its

useful life, under various state and local laws, it may be illegal to dispose of this battery into the municipal waste

stream. Check with your local solid waste officials for details in your area for recycling options or proper disposal.

Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended

by the manufacturer. Discard used battery according to the manufacturer’s instructions.

VIII

Preface

Cleaning

Do not apply cleaner directly to the computer; use a soft clean cloth.

Do not use volatile (petroleum distillates) or abrasive cleaners on any part of the computer.

Servicing

Do not attempt to service the computer yourself. Doing so may violate your warranty and expose you and

the computer to electric shock. Refer all servicing to authorized service personnel. Unplug the computer

from the power supply. Then refer servicing to qualified service personnel under any of the following con-

ditions:

• When the power cord or AC/DC adapter is damaged or frayed.

• If the computer has been exposed to rain or other liquids.

• If the computer does not work normally when you follow the operating instructions.

• If the computer has been dropped or damaged (do not touch the poisonous liquid if the LCD panel breaks).

• If there is an unusual odor, heat or smoke coming from your computer.



Removal Warning

When removing any cover(s) and screw(s) for the purposes of device upgrade, remember to replace the cover(s)

and screw(s) before turning the computer on.

Preface

Travel Considerations

Packing

As you get ready for your trip, run through this list to make sure the system is ready to go:

1. Check that the battery pack and any spares are fully charged.

2. Power off the computer and peripherals.

3. Close the display panel and make sure it’s latched.

4. Disconnect the AC/DC adapter and cables. Stow them in the carrying bag.

5. The AC/DC adapter uses voltages from 100 to 240 volts so you won’t need a second voltage adapter.

However, check with your travel agent to see if you need any socket adapters.

6. Put the notebook in its carrying bag and secure it with the bag’s straps.

7. If you’re taking any peripherals (e.g. a printer, mouse or digital camera), pack them and those devices’

adapters and/or cables.

8. Anticipate customs - Some jurisdictions may have import restrictions or require proof of ownership for

both hardware and software. Make sure your “papers” are handy.



Power Off Before Traveling

Make sure that your notebook is completely powered off before putting it into a travel bag (or any such container).

Putting a notebook which is powered on in a travel bag may cause the Vents/Fan Intakes to be blocked. To pre-

vent your computer from overheating make sure nothing blocks the Vent/Fan Intakes while the computer is in

use.

Preface

On the Road

In addition to the general safety and maintenance suggestions in this preface, and Chapter 8: Troubleshoot-

ing, keep these points in mind:

Hand-carry the notebook - For security, don’t let it out of your sight. In some areas, computer theft is

very common. Don’t check it with “normal” luggage. Baggage handlers may not be sufficiently careful.

Avoid knocking the computer against hard objects.

Beware of Electromagnetic fields - Devices such as metal detectors & X-ray machines can damage the

computer, hard disk, floppy disks, and other media. They may also destroy any stored data - Pass your

computer and disks around the devices. Ask security officials to hand-inspect them (you may be asked to

turn it on). Note: Some airports also scan luggage with these devices.

Fly safely - Most airlines have regulations about the use of computers and other electronic devices in

flight. These restrictions are for your safety, follow them. If you stow the notebook in an overhead com-

partment, make sure it’s secure. Contents may shift and/or fall out when the compartment is opened.

Get power where you can - If an electrical outlet is available, use the AC/DC adapter and keep your bat-

tery(ies) charged.

Keep it dry - If you move quickly from a cold to a warm location, water vapor can condense inside the

computer. Wait a few minutes before turning it on so that any moisture can evaporate.
