Safety information
Electrical safety
Observe the following rules when working on electrical equipments.
Important:
Use only approved tools and test equipments. Some hand tools have handles
covered with a soft material that does not insulate you when working with live
electrical currents.
Many customers have rubber floor mats near their machines that contain small
conductive fibers to decrease electrostatic discharges. Do not use such kind 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 the 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.
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.
Attention: 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.
Attention: An electrical shock can occur only when there is a complete
circuit. 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;
instructions for these precautions are in the safety sections of maintenance
information. Be extremely careful when you measure the 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
it to make sure 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:

Safety information
Safety inspection guide
The purpose of this inspection guide is to assist you in identifying potential
unsafe conditions. As each machine was designed and built, required safety
items were installed to protect users and service personnel from injury. This
guide addresses only those items. You should use good judgment to identify
potential safety hazards according to the attachment of non-Lenovo 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 a bulging capacitor
Mechanical hazards, such as loose or missing hardware
To determine whether there are any potential unsafe conditions, use the
following checklist at the beginning of every service task. 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. Turn 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 the frame ground.
b. The power cord should be the type specified in the parts list.
c. Insulation must not be frayed or worn.
4. Check for cracked or bulging batteries.
5. Remove the cover.
6. Check for any obvious non-Lenovo alterations. Use good judgment as to the
safety of any non-Lenovo alterations.
7. 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.
8. Check for worn, frayed, or pinched cables.
9. Check that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.

G50-30/G50-45/G50-70/G50-70m/Z50-70/Z50-75/G50-80 Hardware Maintenance Manual
Handling devices that are sensitive to electrostatic discharge
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 to guard against ESD damage is desirable but not
necessary.
–
–
Attach the ESD ground clip to any frame ground, ground braid, or green-
wire ground.
When working on a double-insulated or battery-operated system, use an
ESD common ground or reference point. 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.

If an adapter or a device consists of more than one FRU, any of the FRUs
may be the cause of the error. Before replacing the adapter or device,
remove the FRUs one by one to see if the symptoms change. Replace only
the FRU that changed the symptoms.
Attention: The setup configuration on the computer you are servicing may
have been customized. Running Automatic Configuration may alter the
settings. Note the current configuration settings (using the View Configuration
option); then, when service has been completed, verify that those settings
remain in effect.
Strategy for replacing a hard disk drive
Always try to run a low-level format before replacing a hard disk drive. This
will cause all customer data on the hard disk to be lost. Make sure that the
customer has a current backup of the data before performing this action.
Attention: The drive startup sequence in the computer you are servicing may
have been changed. Be extremely careful during write operations such as
copying, saving, or formatting. If you select an incorrect drive, data or programs
can be overwritten.
Important notice for replacing a system board
Some components mounted on a system board are very sensitive. Improper
handling can cause damage to those components, and may cause a system
malfunction.
Attention: When handling a system board:
•
•
•
Do not drop the system board or apply any excessive force to it.
Avoid rough handling of any kind.
Avoid bending the system board and hard pushing to prevent cracking at
each BGA (Ball Grid Array) chipset.

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. If the original FRU parts are non-compliant,
replacement parts can also be non-compliant. In all cases if the original
FRU parts are RoHS compliant, the replacement part must also be RoHS
compliant.
Note: RoHS and non-RoHS FRU part numbers with the same fit and function
are identified with unique FRU part numbers.
Lenovo plans to transit to RoHS compliance well before the implementation
date and expects its suppliers to be ready to support Lenovo’s requirements
and schedule in the EU. Products sold in 2005 and 2006 will contain some
RoHS compliant FRUs. The following statement pertains to these products and
any product Lenovo produces containing RoHS compliant FRUs.
RoHS compliant FRUs have unique FRU part numbers. Before or after the
RoHS implementation date, failed RoHS compliant parts must always be
replaced with RoHS compliant ones, so only the FRUs identified as compliant
in the system HMM or direct substitutions for those FRUs may be used.

Important notes:
• Only certified trained personnel can service the computer.
• Before replacing any FRU, read the entire page on removing and replacing
FRUs.
•
•
Carefully remove screws for reuse when replacing FRUs.
Be extremely careful during such write operations as copying, saving, or
formatting. Drives in the computer that you are servicing sequence might
have been altered. If you select an incorrect drive, data or programs might be
overwritten.
•
•
Replace an FRU only with another FRU of the correct model. When you
replace an FRU, make sure that the machine model and the FRU part number are
correct by referring to the FRU parts list.
An FRU should not be replaced just because of a single, unreproducible failure.
Single failures can occur for a variety of reasons that have nothing to do with a
hardware defect, such as cosmic radiation, electrostatic discharge, or software
errors. Consider replacing an FRU only when a problem recurs. If you suspect that
an FRU is defective, clear the error logs and run the test again. If the error does
not recur, do not replace the FRU.
•
Be careful not to replace a nondefective FRU.
