Preface
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/DCadapter and keep your battery(ies)
charged.
Keep it dry - If you move quickly from acold 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.

Preface
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.

XVII
Preface
Lighting
Proper lighting and a comfortable viewing angle can reduce eye strain and shoulder and neck muscle fatigue.
• 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.
LCD Screen Care
To prevent image persistence on LCD monitors (caused by the continuous display of graphics on the screen for
an extended period of time) take the following precautions:
• Set the Windows Power Plans to turn the screen off after a few minutes of screen idle time.
• Use a rotating, moving or blank screen saver (this prevents an image from being displayed too long).
• Rotate desktop background images every few days.
• Turn the monitor off when the system is not in use.
LCD Electro-Plated Logos
Note that in computers featuring a raised LCD electro-plated logo, the logo is covered by a protective adhesive.
Due to general wear and tear, this adhesive may deteriorate over time and the exposed logo may develop sharp
edges. Be careful when handling the computer in this case, and avoid touching the raised LCD electro-plated
logo. Avoid placing any other items in the carrying bag which may rub against the top of the computer during
transport. If any such wear and tear develops contact your distributor/supplier.
