Hardware Maintenance Manual
General safety
Follow these rules below to ensure general safety:
• Observe a good housekeeping in the area where the machines are put
during and after the maintenance.
• 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 it.
4. Lift it by standing or pushing up with your leg muscles; this action could
avoid 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.
• Do not perform any action that causes hazards to the customer, or that
makes the machine unsafe.
• Before you start the machine, make sure that other service representatives
and the customer are not in a hazardous position.
• Please remove covers and other parts in a safe place, away from all
personnel, while you are servicing the machine.
• Keep your toolcase 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 the
machine. Make sure 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 the
nonconductive clip, about 8 centimeters (3 inches) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for
your clothing.
Attention: 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 may 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.
• Fan louvers on the machine help to prevent the overheating of internal
components. Do not obstruct fan louvers or cover them with labels or
stickers.

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.

Hardware Maintenance Manual
• 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:
– Caution: do not become a victim yourself.
– Switch off the power.
– Send the victim to get medical aid.

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.

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 greenwire ground.
– When working on a double-insulated or battery-operated system, use an
ESD common ground or reference point. You can use coax or connectoroutside 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 service information

Use the following strategy to prevent unnecessary expense for replacing and
servicing FRUs:
• If you are instructed to replace an FRU, but the replacement does not solve
the problem, reinstall the original FRU before you continue.
• Some computers have both a processor board and a system board. If you
are instructed to replace either of them, and replacing one of them does not
solve the problem, reinstall that board, and then replace the other one.
• 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.

Before you go to the checkout, make sure to read the following important notes:

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.

Checking operational charging
To check whether the battery charges properly during operation, use a
discharged battery pack or a battery pack that has less than 50% of the total
power remaining when installed in the computer.
Perform operational charging. If the battery status indicator or icon is not lit,
remove the battery pack and let it return to room temperature. Reinstall the
battery pack. If the charge indicator or icon is still off, replace the battery pack.
If the charge indicator is still not lit, replace the system board.

Checking the battery pack
Battery charging does not start until the Power Meter shows that less than 95%
of the total power remains; under this condition the battery pack can charge to
100% of its capacity. This protects the battery pack from being overcharged or
from having a shortened life.
To check your battery, move your cursor to the Power Meter icon in the icon
tray of the Windows® taskbar and wait for a moment (but do not click it), and the
percentage of battery power remaining is displayed. To get detailed information
about the battery, double-click the Power Meter icon.
Note: If the battery pack becomes hot, it may not be able to be charged.
Remove it from the computer and leave it at room temperature for a while. After
it cools down, reinstall and recharge it.

Passwords
As many as three passwords may be needed for any Lenovo computer: the
power-on password (POP), the hard disk password (HDP), and the supervisor
password.
If any of these passwords has been set, a prompt for it appears on the screen
whenever the computer is turned on. The computer does not start until the
password is entered.

Power-on password
A power-on password (POP) protects the system from being powered on by
an unauthorized person. The password must be entered before an operating
system can be booted.

Hard-disk password
There are two hard-disk passwords (HDPs):
+ User HDP - for the user
+ Master HDP - for the system administrator, who can use it to get access to
the hard disk drive even if the user has changed the user HDP
Attention: If the user HDP has been forgotten, check whether a master HDP
has been set. If it has, it can be used for access to the hard disk drive. If
no master HDP is available, neither Lenovo nor Lenov authorized service
technicians provide any services to reset either the user or the master HDP, or
to recover data from the hard disk drive. The hard disk drive can be replaced
for a scheduled fee.

Supervisor password
A supervisor password protects the system information stored in the BIOS. The
user must enter the supervisor password to get access to the BIOS and change
the system configuration.
Attention: If you forget the password, there is no service procedure to reset
the password. The system board must be replaced for a scheduled fee.
