General safety guidelines

Always observe the following precautions to reduce the risk of injury and property

damage.

Service and upgrades

Do not attempt to service a product yourself unless instructed to do so by the

Customer Support Center or your documentation. Only use a service provider who

is approved to repair your particular product.

Note: Some computer parts can be upgraded or replaced by the customer.

Upgrades typically are referred to as options. Replacement parts approved

for customer installation are referred to as Customer Replaceable Units, or

CRUs. Lenovo provides documentation with instructions when it is

appropriate for customers to install options or replace CRUs. must You

closely follow all instructions when installing or replacing parts. The Off

state of a power indicator does not necessarily mean that voltage levels

inside a product are zero. Before you remove the covers from a product

equipped with an ac power cord, always make sure that the power is turned

off and that the product is unplugged from any power source. For more

information on CRUs, refer to the User Guide for this product. If you have

any questions or concerns, contact the Customer Support Center.

Although there are no moving parts in your computer after the power cord has

been disconnected, the following warnings are required for your safety.

vi User Guide

Danger

Hazardous moving parts. Keep fingers and other body parts away.

Attention

Before replacing any CRUs, turn off the computer and wait three to five

minutes to let the computer cool before opening the cover.

Static electricity prevention

Static electricity, although harmless to you, can seriously damage computer

components and options. Improper handling of static-sensitive parts can cause

damage to the part. When you unpack an option or CRU, do not open the

static-protective package containing the part until the instructions direct you to

install it.

When you handle options or CRUs, or perform any work inside the computer, take

the following precautions to avoid static-electricity damage:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Always handle components carefully. Handle adapters, memory modules, and

other circuit boards by the edges. Never touch exposed circuitry.

v Prevent others from touching components.

v When you install a static-sensitive option or CRU, touch the static-protective

package containing the part to a metal expansion-slot cover or other unpainted

metal surface on the computer for at least two seconds. This reduces static

electricity in the package and your body.

v When possible, remove the static-sensitive part from the static-protective

packaging and install the part without setting it down. When this is not

possible, place the static-protective packaging on a smooth, level surface and

place the part on it.

v Do not place the part on the computer cover or other metal surface.

Power cords and power adapters

Use only the power cords and power adapters supplied by the product

manufacturer.

Important safety information vii

The power cords shall be safety approved. For Germany, it shall be H05VV-F, 3G,

0.75 mm

2

, or better. For other countries, the suitable types shall be used

accordingly.

Never wrap a power cord around a power adapter or other object. Doing so can

stress the cord in ways that can cause the cord to fray, crack, or crimp. This can

present a safety hazard.

Always route power cords so that they will not be walked on, tripped over, or

pinched by objects.

Protect power cord and power adapters from liquids. For instance, do not leave

your power cord or power adapter near sinks, tubs, toilets, or on floors that are

cleaned with liquid cleansers. Liquids can cause a short circuit, particularly if the

power cord or power adapter has been stressed by misuse. Liquids also can cause

gradual corrosion of power cord terminals and/or the connector terminals on a

power adapter, which can eventually result in overheating.

Always connect power cords and signal cables in the correct order and ensure that

all power cord connectors are securely and completely plugged into receptacles.

Do not use any power adapter that shows corrosion at the ac input pins or shows

signs of overheating (such as deformed plastic) at the ac input or anywhere on the

power adapter.

Do not use any power cords where the electrical contacts on either end show signs

of corrosion or overheating or where the power cord appears to have been

damaged in any way.

Voltage-selection switch

Some computers are equipped with a voltage-selection switch located near the

power-cord connection point on the computer. If your computer has a

voltage-selection switch, ensure that you set the switch to match the voltage

available at your electrical outlet. Setting the voltage-selection switch incorrectly

can cause permanent damage to the computer.

If your computer does not have a voltage-selection switch, your computer is

designed to operate only at the voltage provided in the country or region where

the computer was originally purchased.

If you relocate your computer to another country, be aware of the following:

v If your computer does not have a voltage-selection switch, do not connect the

computer to an electrical outlet until you have verified that the voltage provided

is the same as it was in the country or region where the computer was originally

purchased.

v If your computer has a voltage selection switch, do not connect the computer to

an electrical outlet until you have verified that the voltage-selection switch is set

to match the voltage provided in that country or region.

If you are not sure of the voltage provided at your electrical outlet, contact your

local electric company or refer to official sites or other literature for travelers Web

to the country or region where you are located.

viii User Guide

Extension cords and related devices

Ensure that extension cords, surge protectors, uninterruptible power supplies, and

power strips that you use are rated to handle the electrical requirements of the

product. Never overload these devices. If power strips are used, the load should

not exceed the power strip input rating. Consult an electrician for more

information if you have questions about power loads, power requirements, and

input ratings.

Plugs and outlets

If a receptacle (power outlet) that you intend to use with your computer

equipment appears to be damaged or corroded, do not use the outlet until it is

replaced by a qualified electrician.

Do not bend or modify the plug. If the plug is damaged, contact the manufacturer

to obtain a replacement.

Do not share an electrical outlet with other home or commercial appliances that

draw large amounts of electricity; otherwise, unstable voltage might damage your

computer, data, or attached devices.

Some products are equipped with a three-pronged plug. This plug fits only into a

grounded electrical outlet. This is a safety feature. Do not defeat this safety feature

by trying to insert it into a non-grounded outlet. If you cannot insert the plug into

the outlet, contact an electrician for an approved outlet adapter or to replace the

outlet with one that enables this safety feature. Never overload an electrical outlet.

The overall system load should not exceed 80 percent of the branch circuit rating.

Consult an electrician for more information if you have questions about power

loads and branch circuit ratings.

Be sure that the power outlet you are using is properly wired, easily accessible,

and located close to the equipment. Do not fully extend power cords in a way that

will stress the cords.

Be sure that the power outlet provides the correct voltage and current for the

product you are installing.

Carefully connect and disconnect the equipment from the electrical outlet.

External devices

Do not connect or disconnect any external device cables other than USB and 1394

cables while the computer power is on; otherwise, you might damage your

computer. avoid possible damage to attached devices, wait at least five seconds To

after the computer is shut down to disconnect external devices.

Batteries

All personal computers manufactured by Lenovo contain a non-rechargeable coin

cell battery to provide power to the system clock. In addition, many mobile

products, such as notebook computers, utilize a rechargeable battery pack to

provide system power when in portable mode. Batteries supplied by Lenovo for

use with your product have been tested for compatibility and should only be

replaced with approved parts.

Important safety information ix

Never attempt to open or service any battery. Do not crush, puncture, or incinerate

batteries or short circuit the metal contacts. Do not expose the battery to water or

other liquids. Only recharge the battery pack strictly according to instructions

included in the product documentation.

Battery abuse or mishandling can cause the battery to overheat, which can cause

gasses or flame to “vent” from the battery pack or coin cell. If your battery is

damaged, or if you notice any discharge from your battery or the buildup of

foreign materials on the battery leads, stop using the battery and obtain a

replacement from the battery manufacturer.

Batteries can degrade when they are left unused for long periods of time. For some

rechargeable batteries (particularly Lithium Ion batteries), leaving a battery unused

in a discharged state could increase the risk of a battery short circuit, which could

shorten the life of the battery and can also pose a safety hazard. Do not let

rechargeable Lithium-Ion batteries completely discharge or store these batteries in a

discharged state.

Heat and product ventilation

Computers, AC adapters, and many accessories can generate heat when turned on

and when batteries are charging. Always follow these basic precautions:

v Do not leave your computer, AC adapter, or accessories in contact with your lap

or any part of your body for an extended period when the products are

functioning or when the battery is charging. Your computer, AC adapter, and

many accessories produce some heat during normal operation. Extended contact

with the body could cause discomfort or, potentially, a skin burn.

v Do not charge the battery or operate your computer, AC adapter, or accessories

near flammable materials or in explosive environments.

v Ventilation slots, fans, and heat sinks are provided with the product for safety,

comfort, and reliable operation. These features might inadvertently become

blocked by placing the product on a bed, sofa, carpet, or other flexible surface.

Never block, cover, or disable these features.

Inspect your desktop computer for dust accumulation at least once every three

months. Before inspecting your computer, turn off the power and unplug the

computer’s power cord from the electrical outlet; then remove any dust from vents

and perforations in the bezel. If you notice external dust accumulation, then

examine and remove dust from the inside of the computer including heat sink inlet

fins, power supply vents, and fans. Always turn off and unplug the computer

before opening the cover. If possible, avoid operating your computer within 2 feet

of high-traffic areas. If you must operate your computer in or near a high-traffic

area, inspect and, if necessary, clean your computer more frequently.

For your safety and to maintain optimum computer performance, always follow

these basic precautions with your desktop computer:

v Keep the cover closed whenever the computer is plugged in.

v Regularly inspect the outside of the computer for dust accumulation.

v Remove dust from vents and any perforations in the bezel. More frequent

Chapter 1. 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 also can affect the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, here are a few

guidelines to help you find a position that suits you best.

Sitting in the same position for a long time can cause fatigue. A good chair can

make a big difference. The backrest and seat should adjust independently and

provide good support. The seat should have a curved 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 a footrest.

When using the keyboard, keep your forearms parallel to the floor and your wrists

in a neutral, comfortable position. to keep a light touch on the keyboard and Try

your hands and fingers relaxed. can change the angle of the keyboard for You

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 a comfortable 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 a mouse, within easy

reach.

Glare and lighting

Position the monitor to minimize glare and reflections from overhead lights,

windows, and other light sources. Even 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 a window, use curtains or blinds to block the sunlight. You

might have to adjust the brightness and contrast controls on the monitor as the

room lighting changes throughout the day.

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 a soft cloth moistened with a nonabrasive liquid

glass cleaner.

Air circulation

Your computer and monitor produce heat. The computer has a fan 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 a malfunction

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 and 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:

v Avoid the use of extension cords. When possible, plug the computer power cord

directly into an electrical outlet.

v Keep power cords and cables neatly routed away from walkways and other

areas where they might get kicked accidentally.

For more information about power cords, see “Power cords and power adapters”

on page vii and the safety and warranty information that is provided with your

computer.
