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.

Lenovo 3000 N500 Hardware Maintenance Manual
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.
v
v
v
v
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.
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.
Safety information

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. You should use good judgment to identify potential
safety hazards due to attachment of non-Lenovo 3000 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
To determine whether there are any potentially 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. Power off the computer. Disconnect the power cord.
3. Check the power cord for:
4.
5.
6.
7.
8.

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.
Check for cracked or bulging batteries.
Remove the cover.
Check for any obvious non-Lenovo 3000 alterations. Use good judgment as to
the safety of any non-Lenovo 3000 alterations.
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.
Check for worn, frayed, or pinched cables.
Check that the power-supply cover fasteners (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.
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:
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.

for assistance or download information.
Strategy for replacing FRUs
Before replacing parts:
Make sure that all software fixes, drivers, and BIOS downloads are installed
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:
© Copyright Lenovo 2008
17
v If you are instructed to replace a FRU but the replacement does not correct the
problem, reinstall the original FRU before you continue.
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.

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).
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://w3-01.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.

Turn off the computer.
Remove the battery pack.
Connect the ac adapter.
Check that power is supplied when you turn on the computer.
Turn off the computer.
Disconnect the ac adapter and install the charged battery pack.
Check that the battery pack supplies power when you turn on the computer.
If you suspect a power problem, see the appropriate one of the following power
supply checkouts:
v “Checking the AC adapter”
v “Checking operational charging”
v “Checking the battery pack” on page 30
Checking the AC adapter
You are here because the computer fails only when the AC adapter is used.
v If the power-on indicator does not turn on, check the power cord of the AC
adapter for correct continuity and installation.
v If the computer does not charge during operation, go to “Checking operational
charging”
To check the AC adapter, do the following:
1. Unplug the AC adapter cable from the computer.
2. Measure the output voltage at the plug of the AC adapter cable. See the
following figure:

3. If the voltage is not correct, replace the AC adapter.
4. If the voltage is acceptable, do the following:
v Replace the system board.
v If the problem persists, go to “Lenovo 3000 N500” on page 43.
Note: Noise from the AC adapter does not always indicate a defect.
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.
General checkout
29
Perform operational charging. If the battery status indicator or icon does not turn
on, remove the battery pack and let it return to room temperature. Reinstall the
battery pack. If the charge indicator or icon still does not turn on, replace the
battery pack.
If the charge indicator still does not turn on, replace the system board. Then
reinstall the battery pack. If it is still not charged, go to the next section.
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), 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 charge. Remove it
from the computer and leave it at room temperature for a while. After it cools
down, reinstall and recharge it.
To check the battery pack, do the following:
1. Power off the computer.
2. Remove the battery pack and measure the voltage between battery terminals 1
(+) and 7 (-). See the following figure:
1(+)
2(+)
5
3 4
6(-)
Terminal
Voltage (V dc)

3. If the voltage is less than +11.0 V dc, the battery pack has been discharged.
Note: Recharging will take at least 3 hours, even if the indicator does not turn
on.
If the voltage is still less than +11.0 V dc after recharging, replace the battery.
4. If the voltage is more than +11.0 V dc, measure the resistance between battery
terminals 5 and 7. The resistance must be 4 to 30 K .
If the resistance is not correct, replace the battery pack. If the resistance is
correct, replace the system board.

Passwords
As many as three passwords may be needed for any Lenovo 3000 computer: the
power-on password (POP), the hard-disk password (HDP), and the supervisor
password (SVP).
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.
Exception: If only an SVP is installed, the password prompt does not appear when
the operating system is booted.
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):
v User HDP—for the user
v Master HDP—for the system administrator, who can use it to get access to the
hard disk even if the user has changed the user HDP
Note: There are two modes for the HDP: User only and Master + User. The
Master + User mode requires two HDPs; the system administrator enters both in
the same operation. The system administrator then provides the user HDP to the
system user.
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 Lenovo authorized servicers 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.
32
Lenovo 3000 N500 Hardware Maintenance Manual
Supervisor password
A supervisor password (SVP) protects the system information stored in the BIOS
Setup Utility. The user must enter the SVP in order to get access to the BIOS Setup
Utility and change the system configuration.
Attention: If the SVP has been forgotten and cannot be made available to the
servicer, there is no service procedure to reset the password. The system board
must be replaced for a scheduled fee.
How to remove the hard-disk password
Attention: If User only mode is selected and the user HDP has been forgotten
and cannot be made available to the servicer, neither Lenovo nor Lenovo
authorized servicers provide any services to reset the user HDPs or to recover data
from the hard disk drive. The hard disk drive can be replaced for a scheduled fee.
To remove a user HDP that has been forgotten, when the SVP and the master HDP
are known, do the following:
1. Turn on the computer; then, while the initial screen is displayed, press the
Lenovo Care button. The Rescue and Recovery screen opens.

LCD-related symptoms
Important: The TFT LCD for the notebook computer contains many thin-film
transistors (TFTs). The presence of a small number of dots that are missing,
discolored, or always lighted is characteristic of TFT LCD technology, but
excessive pixel problems can cause viewing concerns. The LCD should be
replaced if the number of missing, discolored, or lighted dots in any background
is as follows:

Intermittent problems
Intermittent system hang problems can be due to a variety of causes that have
nothing to do with a hardware defect, such as cosmic radiation, electrostatic
discharge, or software errors. FRU replacement should be considered only when a
problem recurs.
When analyzing an intermittent problem, do the following:
1. Run the diagnostic test for the system board in loop mode at least 10 times.
2. If no error is detected, do not replace any FRUs.
3. If any error is detected, replace the FRU shown by the FRU code. Rerun the
test to verify that no more errors exist.
Undetermined problems
If the diagnostic tests did not identify the adapter or device that has failed, if
wrong devices are installed, or if the system simply is not operating, follow these
procedures to isolate the failing FRU (do not isolate FRUs that have no defects).
Verify that all attached devices are supported by the computer.
Verify that the power supply being used at the time of the failure is operating
correctly. (See “Power system checkout” on page 29.)
1. Turn off the computer.
2. Visually check each FRU for damage. Replace any damaged FRU.
3. Remove or disconnect all of the following devices:
a. Non-Lenovo 3000 devices
b. Devices attached to the docking station or the port replicator
c. Printer, mouse, and other external devices
d. Battery pack
e. Hard disk drive
f. External diskette drive or optical drive
g. DIMM
h. Optical disk or diskette in the internal drive
i. PC Cards
4. Turn on the computer.
5. Determine whether the problem has been solved.
6. If the problem does not recur, reconnect the removed devices one at a time
until you find the failing FRU.
7. If the problem remains, replace the following FRUs one at a time (do not
replace a nondefective FRU):
a. System board
b. LCD assembly

FRU replacement notices
This section contains notices related to removing and replacing parts. Read this
section carefully before replacing any FRU.
Screw notices
Loose screws can cause a reliability problem. In the Lenovo 3000 computer, this
problem is addressed with special nylon-coated screws that have the following
characteristics:
v They maintain tight connections.
v They do not easily come loose, even with shock or vibration.
v They are harder to tighten.
v Each one should be used only once.
Do the following when you service this machine:
v Keep the screw kit (for the P/N, see “Miscellaneous parts” on page 104) in your
tool bag.
v Always use new screws.
v Use a torque screwdriver if you have one.
Tighten screws as follows:
v Plastic to plastic
Turn an additional 90 degrees after the screw head touches the surface of the
plastic part:
90 degrees more
(Cross-section)
v Logic card to plastic
Turn an additional 180 degrees after the screw head touches the surface of the
logic card:
180 degrees more
(Cross-section)
v Torque driver
If you have a torque driver, refer to the “Torque” column for each step.
v Make sure that you use the correct screw. If you have a torque screwdriver,
tighten all screws firmly to the torque shown in the table. Never use a screw
that you removed. Use a new one. Make sure that all of the screws are
tightened firmly.
v Ensure torque screw drivers are calibrated correctly following country

Restoring the serial number of the system unit
When the computer was manufactured, the EEPROM on the system board was
loaded with the serial numbers of the system and all major components. These
numbers need to remain the same throughout the life of the computer.
If you replace the system board, you must restore the serial number of the system
unit to its original value.
Before replacing the system board, save the original serial number by doing the
following:
1. Install the CE Utility Diskette for Lenovo 3000 notebooks, and restart the
computer.
2. From the main menu, select 1. Set System Identification.
3. Select 2. Read S/N data from EEPROM.
The serial number of each device in your computer is displayed; the serial number
of the system unit is listed as follows:
v 20: Serial number
Write down that number.
Note: The serial number of the system unit is also written on the label attached to
the bottom of the computer.
After you have replaced the system board, restore the serial number by doing the
following:
1. Install the CE Utility Diskette for Lenovo 3000 notebooks and restart the
computer.
2. From the main menu, select 1. Set System Identification.
3. Select 1. Add S/N data from EEPROM.
Follow the instructions on the screen.
If the MTM and Product ID numbers differ from each other on the rear label, use
what is shown for the Product ID field. See example below:
MTM on rear label:
TTTT-CTO S/N SSSSSSS
Product ID on rear label:
TTTT-MMM (Use this number when setting Serial Number)
In the example, the Serial Number to be input is ’1STTTTMMMSSSSSSS’.
Retaining the UUID
The Universally Unique Identifier (UUID) is a 128-bit number uniquely assigned to
your computer at production and stored in the EEPROM of your system board.
The algorithm that generates the number is designed to provide unique IDs until
the year A.D. 3400. No two computers in the world have the same number.
50
Lenovo 3000 N500 Hardware Maintenance Manual
When you replace the system board, you must set the UUID on the new system
board as follows:
1. Install the CE Utility Diskette for Lenovo 3000 notebooks, and restart the
computer.
2. From the main menu, select 4. Assign UUID.
A new UUID is created and written. If a valid UUID already exists, it is not
overwritten.
Lenovo 3000 N500
51
Reading or writing the ECA information
Information on Engineering Change Announcements (ECA) are stored in the
EEPROM of the system board. The electronic storage of this information simplifies
the procedure to check if the ECA has been previously applied to a machine. The
machine does not need to be disassembled to check for the ECA application.
To check what ECAs have been previously applied to the machine, use the ECA
Information Read/Write function on the CE Utility Diskette for Lenovo 3000
notebooks.
1. Insert the CE Utility Diskette for Lenovo 3000 notebooks, and restart the
computer.
2. From the main menu, select 6. Set ECA Information.
3. To read ECA information, select 2. Read ECA/rework number from EEPROM
and follow the instruction.
4. To read box build date, select 5. Read box build date from EEPROM, and
follow the instruction on the screen.
After an ECA has been applied to the machine, the EEPROM must be updated to
reflect the ECA’s application. Use the CE Utility Diskette for Lenovo 3000
notebooks to update the EEPROM.
Note: Only the ECA number is stored in the EEPROM. The machine type of the
ECA is assumed be the same as the machine type of the machine that had the ECA
applied to it.
1. Insert the CE Utility Diskette for Lenovo 3000 notebooks, and restart the
computer.
2. From the main menu, select 6. Set ECA Information.
3. To write ECA information, select 1. Write ECA/rework number from EEPROM,
and follow the instruction.
4. To write box build date, select 4. Write box build date from EEPROM, and
follow the instruction on the screen.
If the system board is being replaced, try to read the ECA information from the old
system board and transfer the information to the new system. If the system board
is inoperable, this will not be possible.

Removing and replacing a FRU
This section presents directions and drawings for use in removing and replacing a
FRU. Be sure to observe the following general rules:
1. Do not try to service any computer unless you have been trained and certified.
An untrained person runs the risk of damaging parts.
2. Before replacing any FRU, review “FRU replacement notices” on page 49.
3. Begin by removing any FRUs that have to be removed before the failing FRU.
Any such FRUs are listed at the top of the page. Remove them in the order in
which they are listed.
4. Follow the correct sequence in the steps for removing the FRU, as given in the
drawings by the numbers in square callouts.
5. When turning a screw to replace a FRU, turn it in the direction as given by the
arrow in the drawing.
6. When removing the FRU, move it in the direction as given by the arrow in the
drawing.
7. To put the new FRU in place, reverse the removal procedure and follow any
notes that pertain to replacement. For information about connecting and
arranging internal cables, see “Locations” on page 93.
8. When replacing a FRU, use the correct screw as shown in the procedures.
DANGER
Before removing any FRU, turn off the computer, unplug all power cords from
electrical outlets, remove the battery pack, and then disconnect any
interconnecting cables.
Attention: After replacing a FRU, do not turn on the computer until you have
made sure that all screws, springs, and other small parts are in place and none are
loose inside the computer. Verify this by shaking the computer gently and listening
for rattling sounds. Metallic parts or metal flakes can cause electrical short circuits.
Attention: The system board is sensitive to, and can be damaged by, electrostatic
discharge. Before touching it, establish personal grounding by touching a ground
point with one hand or by using an electrostatic discharge (ESD) strap (P/N
6405959).

Parts list
This section contains following lists of the service parts.
v “Overall” on page 97
v “LCD FRUs” on page 101
v “Keyboard” on page 103
v “Miscellaneous parts” on page 104
v “AC adapters” on page 105
v “Power cords” on page 106
v “Recovery discs” on page 107
v “Common service tools” on page 111
Notes:
v Each FRU is available for all types or models, unless specific types or models
are specified.
v FRU with specific models listed and described as xxU (where U is an example
of a country designator) should be used for all models ending in U.
v FRU with specific models listed and described as 3Dx (where 3D is an
example of a unique configuration) should be used for all of these models,
unless specific country or region designator is specified.
v A CRU (customer replaceable unit) is identified by a single asterisk (*) or two
asterisks (**) in the CRU ID column. An N in the CRU ID column means that
the part is not a CRU. A single asterisk (*) means that the part is a Self-service
CRU; two asterisks (**) means that the part is an Optional-service CRU.
Lenovo 3000 computers contain the following types of CRUs:
Self-service CRUs
These CRUs unplug or are held by no more than two screws.
Examples of these types of CRUs include an AC adapter, a power
cord, a battery, and a hard disk drive. Other Self-service CRUs
depending on product design may include a memory, a wireless card,
a keyboard, and a palm rest with finger print reader and touchpad.
Optional-service CRUs
These CRUs are isolated parts within the computer that are concealed
by an access panel that is typically secured by more than two screws.
Once the access panel is removed, the specific CRU is visible.
v A RoHS compliant FRU is identified by an R. An N in the RoHS ID column
means the part is not a RoHS compliant FRU.
v FRUs marked with OP are available as options.
