Important information about replacing RoHS compliant
FRUs
RoHS, The Restriction of Hazardous Substances in Electrical and Electronic
Equipment Directive (2002/95/EC) is a European Union legal requirement
affecting the global electronics industry. RoHS requirements must be
implemented on Lenovo products placed on the market after June 2006.
Products on the market before June 2006 are not required to have RoHS
compliant parts.

3
Hardware Maintenance Manual
So, if the parts are not compliant originally, replacement parts can also be
noncompliant, but in all cases, if the parts are compliant, the replacement parts
must also be compliant.
Lenovo plans to transition to RoHS compliance well before the implementation
date and expects its suppliers to be ready to support Lenovo’s requirements
and schedule. Products sold in 2005, will contain some RoHS compliant FRUs.
The following statement pertains to these products and any product Lenovo
produces containing RoHS compliant parts.
RoHS compliant Lenovo IdeaCentre A parts have unique FRU part numbers.
Before or after June, 2006, failed RoHS compliant parts must always be
replaced using RoHS compliant FRUs, so only the FRUs identified as compliant
in the system HMM or direct substitutions for those FRUs can be used.
Note: A direct substitution is a part with a different FRU part number that is
automatically shipped by the distribution center at the time of order.

This chapter contains the safety information that you need to be familiar with
before servicing a computer.
General safety
Follow these rules to ensure general safety:
• Observe good housekeeping in the area of the machines during and after
maintenance.
• When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt
to lift.
4. Lift by standing or by pushing up with your leg muscles; this action
removes the strain from the muscles in your back. Do not attempt to lift
any objects that weigh more than 16 kg (35 lb) or objects that you think
are too heavy for you.
• Do not perform any action that causes hazards to the customer, or that
makes the equipment unsafe.
• Before you start the machine, ensure that other service representatives and
the customer’s personnel are not in a hazardous position.
• Place removed covers and other parts in a safe place, away from all
personnel, while you are servicing the machine.
• Keep your tool case away from walk areas so that other people will not trip
over it.
• Do not wear loose clothing that can be trapped in the moving parts of a
machine. Ensure that your sleeves are fastened or rolled up above your
elbows. If your hair is long, fasten it.
• Insert the ends of your necktie or scarf inside clothing or fasten it with a
nonconductive clip, approximately 8 centimeters (3 inches) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for
your clothing.
Safety information

Chapter 2. Safety information
Remember: Metal objects are good electrical conductors.
• Wear safety glasses when you are: hammering, drilling, soldering, cutting
wire, attaching springs, using solvents, or working in any other conditions
that might be hazardous to your eyes.
• After service, reinstall all safety shields, guards, labels, and ground wires.
Replace any safety device that is worn or defective.
• Reinstall all covers correctly before returning the machine to the customer.
Electrical safety
CAUTION:
Electrical current from power, telephone, and communication cables can
be hazardous. To avoid personal injury or equipment damage, disconnect
the attached power cords, telecommunication systems, networks, and
modems before you open the server/workstation covers, unless
instructed otherwise in the installation and configuration procedures.
Observe the following rules when working on electrical equipment.
Important: Use only approved tools and test equipment. Some hand tools have
handles covered with a soft material that does not insulate you when
working with live electrical currents.
Many customers have, near their equipment, rubber floor mats that
contain small conductive fibers to decrease electrostatic discharges.
Do not use this type of mat to protect yourself from electrical shock.
• Find the room emergency power-off (EPO) switch, disconnecting switch, or
electrical outlet. If an electrical accident occurs, you can then operate the
switch or unplug the power cord quickly.
• Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
• Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
• Before you start to work on the machine, unplug the power cord. If you
cannot unplug it, ask the customer to power-off the wall box that supplies
power to the machine and to lock the wall box in the off position.

Hardware Maintenance Manual
• If you need to work on a machine that has exposed electrical circuits,
observe the following precautions:
– Ensure that another person, familiar with the power-off controls, is near
you.
Remember: Another person must be there to switch off the power, if
necessary.
– Use only one hand when working with powered-on electrical equipment;
keep the other hand in your pocket or behind your back.
Remember: There must be a complete circuit to cause electrical shock. By
observing the above rule, you may prevent a current from passing through
your body.
– When using testers, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate
you from grounds such as metal floor strips and machine frames.
Observe the special safety precautions when you work with very high
voltages; these instructions are in the safety sections of maintenance
information. Use extreme care when measuring high voltages.
• Regularly inspect and maintain your electrical hand tools for safe operational
condition.
• Do not use worn or broken tools and testers.
• Never assume that power has been disconnected from a circuit. First, check
that it has been powered-off.
• Always look carefully for possible hazards in your work area. Examples of
these hazards are moist floors, nongrounded power extension cables, power
surges, and missing safety grounds.
• Do not touch live electrical circuits with the reflective surface of a plastic
dental mirror. The surface is conductive; such touching can cause personal
injury and machine damage.
• Do not service the following parts with the power on when they are removed
from their normal operating places in a machine:
– Power supply units
–Pumps
– Blowers and fans
– Motor generators
and similar units. (This practice ensures correct grounding of the units.)
• If an electrical accident occurs:
– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.

Chapter 2. Safety information
Safety inspection guide
The intent of this inspection guide is to assist you in identifying potentially
unsafe conditions on these products. Each machine, as it was designed and
built, had required safety items installed to protect users and service personnel
from injury. This guide addresses only those items. However, good judgment
should be used to identify potential safety hazards due to attachment of
features or options not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the
apparent hazard could be and whether you can continue without first correcting
the problem.
Consider these conditions and the safety hazards they present:
• Electrical hazards, especially primary power (primary voltage on the frame
can cause serious or fatal electrical shock).
• Explosive hazards, such as a damaged CRT face or bulging capacitor
• Mechanical hazards, such as loose or missing hardware
The guide consists of a series of steps presented in a checklist. Begin the
checks with the power off, and the power cord disconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Power-off the computer. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. Use a meter to measure
third-wire ground continuity for 0.1 ohm or less between the external
ground pin and frame ground.
b. The power cord should be the appropriate type as specified in the parts
listings.
c. Insulation must not be frayed or worn.
4. Remove the cover.
5. Check for any obvious alterations. Use good judgment as to the safety of any
alterations.
6. Check inside the unit for any obvious unsafe conditions, such as metal
filings, contamination, water or other liquids, or signs of fire or smoke
damage.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.

Hardware Maintenance Manual
Handling electrostatic discharge-sensitive devices
Any computer part containing transistors or integrated circuits (ICs) should be
considered sensitive to electrostatic discharge (ESD). ESD damage can occur
when there is a difference in charge between objects. Protect against ESD
damage by equalizing the charge so that the machine, the part, the work mat,
and the person handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements
noted here.
2. Make sure that the ESD protective devices you use have been certified (ISO
9000) as fully effective.
When handling ESD-sensitive parts:
• Keep the parts in protective packages until they are inserted into the product.
• Avoid contact with other people.
• Wear a grounded wrist strap against your skin to eliminate static on your
body.
• Prevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
• Use the black side of a grounded work mat to provide a static-free work
surface. The mat is especially useful when handling ESD-sensitive devices.
• Select a grounding system, such as those listed below, to provide protection
that meets the specific service requirement.
Note: The use of a grounding system is desirable but not required to protect
against ESD damage.
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire
ground.
– Use an ESD common ground or reference point when working on a double-
insulated or battery-operated system. You can use coax or connector-outside
shells on these systems.
– Use the round ground-prong of the ac plug on ac-operated computers.
Grounding requirements
Electrical grounding of the computer is required for operator safety and correct
system function. Proper grounding of the electrical outlet can be verified by a
certified electrician.
