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.
Power Safety Warning
Before you undertake any upgrade procedures, make sure that you have turned off
the power, and disconnected all peripherals and cables (including telephone lines).
It is advisable to also remove you battery in order to prevent accidentally turning the
machine on.

explode, leak or damage the computer.
• 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 qual¬ified service personnel.

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 hard¬ware and software. Make sure your
documents are prepared.
Power Off Before Traveling
Make sure that your notebook is completely powered off before putting it into a
travel bag (or any other such container). Putting a notebook which is powered on
in a travel bag may cause the Vents/Fan Intakes to be blocked. To prevent your
computer from overheating make sure nothing blocks the Vent/Fan Intakes while the
computer is in use.

On the Road
In addition to the general safety and maintenance suggestions in this preface, and
Chapter 8: Troubleshooting, 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 knock¬ing the computer
against hard objects.
Beware of Electromagnetic fields - Devices such as metal detectors & X-ray
machines can damage the com¬puter, 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 compartment, 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 battery(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.

Developing Good Work Habits
Developing good work habits is important if you need to work in front of the computer
for long periods of time. Improper work habits can result in discomfort or serious injury
from repetitive strain to your hands, wrists or other joints. The following are some tips
to reduce the strain:
• Adjust the height of the chair and/or desk so that the keyboard is at or
slightly below the level of your elbow. Keep your forearms, wrists, and hands
in a relaxed position.
• Your knees should be slightly higher than your hips. Place your feet flat on the
floor or on a footrest if necessary.
• Use a chair with a back and adjust it to support your lower back comfortably.
• Sit straight so that your knees, hips and elbows form approximately
90-degree angles when you are working.
• Take periodic breaks if you are using the computer for long periods of time.
Remember to:
• Alter your posture frequently.
• Stretch and exercise your body several times a day.
• Take periodic breaks when you work at the computer for long
periods of time. Frequent and short breaks are better than fewer
and longer breaks.
Lighting
Proper lighting and comfortable display viewing angle can reduce eye strain and
muscle fatigue in your neck and shoulders.
• Position the display to avoid glare or reflections from overhead lighting or
outside sources of light.
• Keep the display screen clean and set the brightness and contrast to levels
that allow you to see the screen clearly.
• Position the display directly in front of you at a comfortable viewing distance.
• Adjust the display-viewing angle to find the best position.
