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 damaged.

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

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

aged.

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.

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 specifications, 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 current load

of all the connected devices.

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

plies (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.
