servicing FRUs:
© Copyright Lenovo 2006
1
Important service information
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.
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 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 Custom Model Variant (CMV) products
Custom Model Variant (CMV) is a unique configuration that has been negotiated
between 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.
There are three information resources to identify which FRUs are used to support
CMV products. These sources are PC Entitlement Warehouse (PEW), eSupport, and
the HMM.

MT 0761
Important service information
Using PC Entitlement Warehouse (PEW)
v PEW is the primary source for identifying FRU part numbers and FRU
descriptions for the key commodities for CMV 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 CMV products are loaded in PEW under the 4-digit MT and
3-digit model, where model = “fixed part number”.
v PEW can be accessed at the following Web site:
http://w3-3.ibm.com/pc/entitle
Customers can also access PEW via
http://www-307.ibm.com/pc/support/site.wss/product.do?template=/
warranty/warranty.vm&sitestyle=lenovo
Click on MACHINE LOOKUP, followed by WARRANTY INFORMATION. Input
the MT and the Serial number and the list of key commodities will be returned
in the PEW record under COMPONENT INFORMATION.
v Business Partners using Eclaim will access PEW when performing Entitlement
Lookup. Business Partners will enter Loc ID, MT and Serial, and the key
commodities will be returned in the Eclaim record under SYSTEM DETAILS.
v Authorized IBM Business Partners can access Eclaim at the following Web site:
https://wca.eclaim.com
Using eSupport
For Key Commodities (Examples - hard disk drive, system board,
microprocessor, LCD, and memory)
v eSupport can be used to view the list of key commodities built in a particular
machine serial (this is the same record found in PEW).
v eSupport can be accessed at the following Web site:
http://www.lenovo.com/support
v To view the key commodities, click on PARTS INFORMATION, then PARTS
LOOKUP. Type in the model type and serial number. The key commodities will
be returned in the eSupport record under PARTS SHIPPED WITH YOUR
SYSTEM.
For the Remaining FRUs (the complete list of FRUs at the MT Model level)
v eSupport can be used to view the complete list of FRUs for a machine type and
model.
v To view the complete list of FRUs, type in the machine type and model
(Example: 1829-CTO) under QUICK PATH. Under “View by Document Type”
select PARTS INFORMATION. Under “Filter by Category” select SERVICE
PARTS. Under “Parts Information by Date” select SYSTEM SERVICE PARTS. The
list of service parts by description, with applicable machine type model and FRU
will be displayed.
Using the HMM
Use the HMM as a back-up to PEW and eSupport to view the complete list of
FRUs at the MT Model level. CMVs are custom models and are not found in the
HMM.

Important service information
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.
So, 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.
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. Products sold in 2005, 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 information
Safety information
The following section presents safety information with which you need to be
familiar before you service a Lenovo 3000 computer.
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.

Electrical safety
Observe the following rules when working on electrical equipment.
Introduction
11
Safety information
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.
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.
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.
Safety information
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:
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. Remove the cover.
5. Check for any obvious non-Lenovo 3000 alterations. Use good judgment as to
the safety of any non-Lenovo 3000 alterations.
6. 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.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been
removed or tampered with.
Introduction

Safety information
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.

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.
Supervisor password:
A supervisor password (SVP) protects the system information stored in the BIOS
Utility. The user must enter the SVP in order to get access to the BIOS 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 power-on password
To remove a POP that you have forgotten, do the following:
(A) If no SVP has been set:
1. Turn off the computer.
2. Remove the battery pack.
For how to remove the battery pack, see “1010 Battery pack” on page 43.

operation with the keyboard, the hard disk, the parallel connector, or the
diskette drive within that time.
v If the battery indicator blinks orange, indicating that the battery power is low.
(Alternatively, if Hibernate when battery becomes low has been selected in the
“Power Management Properties” window, the computer goes into hibernation
mode.)
Note for the Advanced Power Management (APM) and Advanced Configuration
and Power Interface (ACPI) operating system:
Even if you do not set the low-battery alarm, the charge indicator notifies you
when the battery is low, and then the computer enters the power-saving mode
automatically. This default low-battery behavior is independent of the operating
system; so if you have set the low-battery alarm, the computer may not do what
you specified. It chooses either your setting or the default setting, whichever is
appropriate.
If you are using the ACPI operating system, only the low-battery alarm is
available.
To cause the computer to return from standby mode and resume operation, do one
of the following:
v Press the Fn key.
v Open the LCD cover.
v Turn on the power switch.
Also, in either of the following events, the computer automatically returns from

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 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 5 (−). See the following figure:

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 4 and 5. 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.

Symptom-to-FRU index
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:
v XGA: 8 or more bright dots, 8 or more dark dots, or a total of 9 or more
bright and dark dots.
Note: A bright dot means a pixel is always on (white or color.) A dark dot
means a pixel is always off (black color.)

Symptom-to-FRU index
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 26.)
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 port replicator
c. Printer, mouse, and other external devices
d. Battery pack
e. Hard disk drive
f. External diskette drive
g. DIMM
h. CD-ROM and diskette drive in the Ultrabay
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
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 79) 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
specifications.
Retaining serial numbers
This section includes the following descriptions:
v “Restoring the serial number of the system unit” on page 40
Lenovo 3000 C100
39
FRU replacement notices
v “Retaining the UUID”
v “Reading or writing the ECA information”
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 Lenovo 3000 Hardware Maintenance Diskette Version 1.73 or later,
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 Lenovo 3000 Hardware Maintenance Diskette Version 1.73 or later
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.
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.
When you replace the system board, you must set the UUID on the new system
board as follows:
1. Install the Lenovo 3000 Hardware Maintenance Diskette Version 1.73 or later,
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.
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.
40
MT 0761
FRU replacement notices
To check what ECAs have been previously applied to the machine, use the ECA
Information Read/Write function on the Lenovo 3000 Hardware Maintenance
Diskette Version 1.73 or later.
1. Insert the Lenovo 3000 Hardware Maintenance Diskette Version 1.73 or later,
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 Lenovo 3000 Hardware Maintenance Diskette
Version 1.73 or later to update the EEPROM.
Note: Only the ECA number is stored in the EEPROM. The machine type of the

Removing and replacing a FRU
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 39.
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 70.
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).
