What if you are traveling?

It might not be possible to observe the best ergonomic practices when you are using your computer while
on the move or in a casual setting. Regardless of the setting, try to observe as many of these tips as
possible. Sitting properly and using adequate lighting, for example, will help you maintain desirable levels
of comfort and performance.

Questions about vision?

The visual display screens of ThinkPad notebook computers are designed to meet the highest standards
and to provide you with clear, crisp images and large, bright displays that are easy to see, yet easy on the
eyes. Of course, any concentrated and sustained visual activity can be tiring. If you have questions on eye
fatigue or visual discomfort, consult a vision care specialist for advice.

Comfort

Observe the following guidelines to achieve greater comfort and improve performance.

Active sitting and rest breaks

: The longer you sit and work with your computer, the more important it is to

observe your working posture. Follow “Ergonomic information” on page 43 and practice “active sitting” to
avoid discomfort associated with your working postures. Making minor voluntary postural changes and
taking short frequent work breaks are the key ingredients for healthy computing. Your computer is light and
mobile; you can easily reposition your working surface to accommodate many posture modifications.

Work area setup options

: Familiarize yourself with all of your office furniture so that you know how to adjust

your work surface, seat, and other work tools to accommodate your preferences for comfort. If your work
area is not in an office setting, be sure to take special note of employing active sitting and taking work
breaks. Many ThinkPad product solutions are available to help you modify and expand your computer to
best suit your needs. You can find some of these options at http://www.lenovo.com/essentials. Explore your
options for docking solutions and external products that provide the adjustability and features that you want.
