Usethefollowingstrategytopreventunnecessaryexpenseforreplacing and
servicing FRUs:
v If youareinstructedtoreplaceaFRUbutthereplacementdoesnotcorrectthe
problem, reinstall the original FRU before you continue.
v Some computershavebothaprocessorboardandasystemboard.Ifyouare
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 anadapteroradeviceconsistsofmorethanoneFRU,anyoftheFRUsmay
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 setupconfigurationonthecomputeryouareservicingmayhave
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 drivestartupsequenceinthecomputeryouareservicingmay
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 handlingasystemboard:
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 messages
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.
Strategy for replacing FRUs for CTO, CMV, and GAV
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).

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 and sold in the
European Union 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.

Safety notices
Safety notice 7
DANGER
Though the main batteries have low voltage, a shorted or grounded battery can
produce enough current to burn personnel or combustible materials.
Bien que le voltage des batteries principales soit peu élevé, le court-circuit ou la mise
à la masse d’une batterie peut produire suffisamment de courant pour brûler des
matériaux combustibles ou causer des brûlures corporelles graves.
Obwohl Hauptbatterien eine niedrige Spannung haben, können sie doch bei
Kurzschluß oder Erdung genug Strom abgeben, um brennbare Materialien zu
entzünden oder Verletzungen bei Personen hervorzurufen.
Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in corto
circuito o a massa può fornire corrente sufficiente da bruciare materiali combustibili o
provocare ustioni ai tecnici di manutenzione.
Aunque las baterías principales tienen un voltaje bajo, una batería cortocircuitada o
con contacto a tierra puede producir la corriente suficiente como para quemar material
combustible o provocar quemaduras en el personal.
Before removing any FRU, power off the computer, unplug all power cords from
electrical outlets, remove the battery pack, and then disconnect any interconnecting
cables.
Avant de retirer une unité remplaçable en clientèle, mettez le système hors tension,
débranchez tous les cordons d’alimentation des socles de prise de courant, retirez la
batterie et déconnectez tous les cordons d’interface.
Die Stromzufuhr muß abgeschaltet, alle Stromkabel aus der Steckdose gezogen, der
Akku entfernt und alle Verbindungskabel abgenommen sein, bevor eine FRU entfernt
wird.
Prima di rimuovere qualsiasi FRU, spegnere il sistema, scollegare dalle prese elettriche
tutti i cavi di alimentazione, rimuovere la batteria e poi scollegare i cavi di
interconnessione.
Antes de quitar una FRU, apague el sistema, desenchufe todos los cables de las tomas
de corriente eléctrica, quite la batería y, a continuación, desconecte cualquier cable de

Safety information
Safety information
The following section presents safety information with which you need to be
familiar before you service a ThinkPad computer.
General safety
Follow these rules to ensure general safety:
v Observe goodhousekeepingintheareaofthemachinesduringandafter
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 theroomemergencypower-off(EPO)switch,disconnectingswitch,or
electrical outlet. If an electrical accident occurs, you can then operate the switch
or unplug the power cord quickly.
v Do notworkaloneunderhazardousconditionsornearequipmentthathas
hazardous voltages.
v Disconnect allpowerbefore:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing Field Replaceable Units (FRUs)
Beforeyoustarttoworkonthemachine,unplugthepowercord. If you cannot
v
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 youneedtoworkonamachinethathasexposed electricalcircuits,observethe
following precautions:
– Ensure that another person, familiar with the power-off controls, is near you.
Attention: Another personmustbetheretoswitchoffthepower,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 electricalshockcanoccuronlywhenthereisacomplete
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 inspectandmaintainyourelectricalhandtoolsforsafeoperational
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 lookcarefullyforpossiblehazardsinyourworkarea.Examplesofthese
hazards are moist floors, nongrounded power extension cables, power surges,
and missing safety grounds.
v Do nottouchliveelectricalcircuitswiththereflectivesurfaceofaplasticdental
mirror. The surface is conductive; such touching can cause personal injury and
machine damage.
Introduction 17
Safety information
Safety inspection guide
v Do notservicethefollowingpartswith thepoweronwhentheyareremoved
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 anelectricalaccidentoccurs:
– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.
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,especiallyprimarypower(primaryvoltageontheframecan
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
9.Checkthatthepower-supplycoverfasteners(screws or rivets) have not been
removed or tampered with.
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.
2.MakesurethattheESDprotectivedevicesyouusehavebeencertified
(ISO 9000) as fully effective.
WhenhandlingESD-sensitiveparts:
v Keep the parts in protective packages until they are inserted into the product.
v Avoid contact with other people while handling the part.
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 theblacksideofagroundedworkmattoprovideastatic-freeworksurface.
The mat is especially useful when handling ESD-sensitive devices.
v Select agroundingsystem,suchasthoselistedbelow,toprovideprotectionthat
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. 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.
