Chapter 2. Arranging your workspace
To get the most from your computer, arrange both the equipment you use and
your work area to suit your needs and the kind of work you do. Your comfort is of
foremost importance, but light sources, air circulation, and the location of electrical
outlets can also affect the way you arrange your workspace.
Comfort
Although no single working position is ideal for everyone, here are afew
guidelines to help you find aposition that suits you best.
Sitting in the same position for along time can cause fatigue. The backrest and
seat of your chair should adjust independently and provide good support. The seat
should have acurved front to relieve pressure on the thighs. Adjust the seat so
that your thighs are parallel to the floor and your feet are either flat on the floor or
on afootrest.
When using the keyboard, keep your forearms parallel to the floor and your wrists
in acomfortable position. Use alight touch on the keyboard and your hands and
fingers relaxed. Change the angle of the keyboard for maximum comfort by
adjusting the position of the keyboard feet.
Viewing Distance
Lower
Back
Support
Seat
Height
Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place
the monitor at acomfortable viewing distance, usually 51 to 61 cm (20 to 24 in.),
and position it so you can view it without having to twist your body. Also,
position other equipment you use regularly, such as the telephone or amouse,
within easy reach.
Glare and lighting
Position the monitor to minimize glare and reflections from overhead lights,
windows, and other light sources. Reflected light from shiny surfaces can cause
annoying reflections on your monitor screen. Place the monitor at right angles to
windows and other light sources, when possible. Reduce overhead lighting, if
necessary, by turning off lights or using lower wattage bulbs. If you install the
monitor near awindow, use curtains or blinds to block the sunlight. You can adjust
the brightness and contrast controls on the monitor as the room lighting changes
throughout the day.
©Lenovo 2005, 2007. Portions ©IBM Corp. 2005. 3

Where it is impossible to avoid reflections or to adjust the lighting, an antiglare
filter placed over the screen might be helpful. However, these filters might affect
the clarity of the image on the screen; try them only after you have exhausted
other methods of reducing glare.
Dust buildup compounds problems associated with glare. Remember to clean your
monitor screen periodically using asoft cloth moistened with anonabrasive liquid
glass cleaner.
Air circulation
Your computer and monitor produce heat. The computer has afan that pulls in
fresh air and forces out hot air. The monitor lets hot air escape through vents.
Blocking the air vents can cause overheating, which might result in amalfunction
or damage. Place the computer and monitor so that nothing blocks the air vents;
usually, 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air is
not blowing on someone else.
Electrical outlets and cable lengths
The location of electrical outlets, the length of power cords and cables that connect
to the monitor, printer, and other devices might determine the final placement of
your computer.
When arranging your workspace:
vAvoid the use of extension cords. When possible, plug the computer power cord
directly into an electrical outlet.
vKeep power cords and cables neatly routed away from walkways and other
areas where they might get kicked accidentally.
For more information about power cords, refer to the Safety and Warranty Guide
that was provided with your computer.

habits. For more information, see Chapter 2, “Arranging your workspace,” on page
3.
Installing the vertical stand
Depending on your computer, avertical stand can be used to place your computer
in the vertical position. If your computer comes with avertical stand, do the
following to install the stand:
1. Position your computer in the vertical position with the air vents facing
downward.
2. Align the tab on the vertical stand with the notch on the computer as shown.
3. Pivot the vertical stand towards the front of the computer until it snaps into
position.
4. Carefully, position the computer with the air vents facing upward so that the
computer sits on the vertical stand.

Connecting your computer
Use the following information when connecting your computer. Look for the small
connector icons on the back of your computer.
Important
Setting the voltage-selection switch incorrectly can cause permanent damage
to the computer.
If you are not sure of the voltage provided at your electrical outlet, contact
your local electric company or refer to official Web sites or other literature for
travelers to the country or region where you are located.
Note: Your computer might not have all of the switches or connectors described in
this section.
If your computer cables and connector panel have color-coded connectors, match
the color of the cable end with the color of the connector. For example, match a
blue cable end with ablue connector or ared cable end with ared connector.
1. Some models are equipped with avoltage-selection switch located near the
power-cord connection point on the computer.
If your computer has avoltage-selection switch, ensure that you set the
voltage-selection switch to match the voltage available at your electrical outlet.
If necessary, use aballpoint pen to slide the switch to adifferent position.
vIf the voltage supply range in your local country or region is 100–127 Vac,
set the switch to 115 V.
vIf the voltage supply range is in your local country or region is 200–240 V
ac, set the switch to 230 V.
