General safety

Follow these rules to ensure general safety:

v Observe good housekeeping in the area of the machines during and after

maintenance.

v When lifting any heavy object:

1. Make sure that 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 object that

weighs more than 16 kg (35 lb) or that you think is too heavy for you.

v Do not perform any action that causes hazards to the customer, or that makes

the equipment unsafe.

v Before you start the machine, make sure that other service representatives and

the customer’s personnel are not in a hazardous position.

v Place removed covers and other parts in a safe place, away from all personnel,

while you are servicing the machine.

v Keep your toolcase away from walk areas so that other people will not trip over

it.

v Do not wear loose clothing that can be trapped in the moving parts of a

machine. Make sure that your sleeves are fastened or rolled up above your
elbows. If your hair is long, fasten it.

v Insert the ends of your necktie or scarf inside clothing or fasten it with a

nonconductive clip, about 8 centimeters (3 inches) from the end.

v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your

clothing.
Attention: Metal objects are good electrical conductors.

v 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.

v After service, reinstall all safety shields, guards, labels, and ground wires.

Replace any safety device that is worn or defective.

v Reinstall all covers correctly before returning the machine to the customer.

v Fan louvers on the machine help to prevent overheating of internal components.

Do not obstruct fan louvers or cover them with labels or stickers.

Electrical safety

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.

v 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.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Disconnect all power before:

– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units

v 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.

v 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. Use extreme care when measuring high voltages.

v Regularly inspect and maintain your electrical hand tools for safe operational

condition.

v Do not use worn or broken tools and testers.

v Never assume that power has been disconnected from a circuit. First, check that it

has been powered off.

v 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.

Safety information 3

v 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.

v 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.)

v If an electrical accident occurs:

– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.

Safety inspection guide

The purpose of this inspection guide is to assist you in identifying potentially
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. Yo u should use good judgment to identify potential
safety hazards due to attachment of non-ThinkPad 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:

v Electrical hazards, especially primary power (primary voltage on the frame can

cause serious or fatal electrical shock)

v Explosive hazards, such as a damaged CRT face or a bulging capacitor

v Mechanical hazards, such as loose or missing hardware

determine whether there are any potentially unsafe conditions, use the

To
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. 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 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-ThinkPad alterations. Use good judgment as to the

safety of any non-ThinkPad 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.

Safety information 5

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:

v Keep the parts in protective packages until they are inserted into the product.

v Avoid contact with other people.

v Wear a grounded wrist strap against your skin to eliminate static on your body.

v Prevent the part from touching your clothing. Most clothing is insulative and

retains a charge even when you are wearing a wrist strap.

v 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.

v Select a grounding system, such as those listed below, to provide protection that

meets the specific service requirement.

Note:

use of a grounding system to guard against ESD damage is desirable but not

The
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. Yo u 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.

Important:

BIOS and device driver fixes are customer-installable. The BIOS and device
drivers are posted on the customer support site http://www.lenovo.com/support

Advise customers to contact the Customer Support Center at 800-426-7378 if they
need assistance in obtaining or installing any software fixes, drivers, and BIOS
downloads.

Customers in Canada should call the Customer Support Center at 800-565-3344
for assistance or download information.

Strategy for replacing FRUs

Before replacing parts:

sure that all software fixes, drivers, and BIOS downloads are installed

Make
before replacing any FRUs listed in this manual.

After a system board is replaced, ensure that the latest BIOS is loaded to the
system board before completing the service action.

To download software fixes, drivers, and BIOS, do as follows:

1. Go to http://www.lenovo.com/support

2. Enter the product number of the computer or press Auto-detect button on the

screen.

3. Select Downloads and drivers.

4. Follow the directions on the screen and install the necessary software.

Use the following strategy to prevent unnecessary expense for replacing and
servicing FRUs:

v If you are instructed to replace a FRU but the replacement does not correct the

problem, reinstall the original FRU before you continue.

© Copyright Lenovo 2007, 2008 17

v Some computers have both a processor board and a system board. If you are

instructed to replace either the processor board or the system board, and
replacing one of them does not correct the problem, reinstall that board, and
then replace the other one.

v 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. Be sure that the customer has a
current backup of the data before doing this task.

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 of a system board can cause damage to those components, and may
cause a system malfunction.

Attention: When handling a system board:

v Do not drop a system board or apply any excessive force to it.

v Avoid rough handling of any kind.

v Avoid bending a system board and hard pushing to prevent cracking at each

BGA (Ball Grid Array) chipset.

How to use error message

Use the error codes displayed on the screen to diagnose failures. If more than one
error code is displayed, begin the diagnosis with the first error code. Whatever
causes the first error code may also cause false error codes. If no error code is
displayed, see whether the error symptom is listed in the Symptom-to-FRU Index
for the computer you are servicing.

Product definition

Dynamic Configure To Order (CTO)

This provides the ability for a customer to configure an IBM® or a Lenovo

™

solution from an eSite, and have this configuration sent to fulfillment, where it is
built and shipped directly to the customer. The machine label, Product Entitlement
Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit
MT and 3-digit model, where model = “CTO” (Example: 1829-CTO).

Custom Model Variant (CMV)

This is a unique configuration that has been negotiated between IBM or Lenovo
and the customer. A unique 4-digit MT and 3-digit model is provided to the
customer to place orders (Example: 1829-W15). A CMV is a special bid offering.
Therefore, it is NOT generally announced.

v The MTM portion of the machine label is the 4-digit MT and 3-digit model,

where model = “CTO” (Example: 1829-CTO). The PRODUCT ID portion of the
machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15).

v The PEW record is the 4-digit MT and 3-digit model, where model = “CTO”

(Example: 1829-CTO).

v eSupport will show both the CTO and CMV machine type models (Example:

1829-CTO and 1829-W15 will be found on the eSupport site.)

v The HMM will have the 4-digit MT and 3-digit CTO model only (Example:

1829-CTO). Again, CMVs are custom models and are not found in the HMM.

General Announce Variant (GAV)

This is a standard model (fixed configuration). GAVs are announced and offered to
all customers. The MTM portion of the machine label is a 4-digit MT and 3-digit
model, where model = a “fixed part number”, not “CTO” (Example: 1829-F1U).
Also, PEW, eSupport, and the HMM will list these products under the same fixed
model number.

FRU identification for CTO, CMV, and GAV products

There are three information resources to identify which FRUs are used to support
CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM.

Using PEW

v PEW is the primary source for identifying FRU part numbers and FRU

descriptions for the key commodities for CTO, CMV and GAV products at a MT

- serial number level. An example of key commodities are hard disk drives,
system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.

v Remember, all CTO and CMV products are loaded in PEW under the 4-digit MT

and 3-digit model, where model = “CTO” (Example: 1829-CTO). GAVs are
loaded in PEW under the 4-digit MT and 3-digit model, where model = a “fixed
part number”, not “CTO” (Example: 1829-F1U).

v PEW can be accessed at the following Web site: http://w3-3.ibm.com/pc/

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 transition 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 using
RoHS compliant FRUs, so only the FRUs identified as compliant in the system
HMM or direct substitutions for those FRUs may be used.

Important notes:

v Only certified trained personnel should service the computer.
v Before replacing any FRU, read the entire page on removing and replacing

FRUs.

v When you replace FRUs, use new nylon-coated screws.
v 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.

v Replace a FRU only with another FRU of the correct model. When you

replace a FRU, make sure that the model of the machine and the FRU part
number are correct by referring to the FRU parts list.

v A FRU should not be replaced 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 a FRU only when a problem recurs. If you
suspect that a FRU is defective, clear the error log and run the test again. If
the error does not recur, do not replace the FRU.

v Be careful not to replace a nondefective FRU.
