T470p Hardware Maintenance Manual

Chapter 1. Safety information
This chapter presents following safety information that you need to be familiar with before you service a
ThinkPad notebook computer.
• “General safety” on page 1
• “Electrical safety” on page 1
• “Safety inspection guide” on page 2
• “Handling devices that are sensitive to electrostatic discharge” on page 3
• “Grounding requirements” on page 4
• “Safety notices (multilingual translations)” on page 4

General safety
Follow these rules to ensure general safety:
• Observe good housekeeping in the area of the machines during and after 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.

•
•
•
•
•
•
•

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.
Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.
Before you start the machine, make sure that other service technicians and the customer's personnel are
not in a hazardous position.
Place removed 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 a 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 a 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 might 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 overheating of internal components. Do not obstruct fan
louvers or cover them with labels or stickers.

Electrical safety
Observe the following rules when working on electrical equipment.
Important: Use only approved tools and test equipment. Some hand tools have handles covered with a soft
material that does not insulate you when working with live electrical currents.Many customers have, near
their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges.
Do not use this type of mat to protect yourself from electrical shock.

• 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 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. 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.
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
– Similar units as listed above
This practice ensures correct grounding of the units.
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 technicians
from injury. This guide addresses only those items. You 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.

T470p Hardware Maintenance Manual

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 cathode ray tube (CRT) face or a bulging capacitor
• 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 authorized type specified for your computer. Go to:
http://www.lenovo.com/serviceparts-lookup
c. Insulation must not be frayed or worn.
4. Check for cracked or bulging batteries.
5. Remove the cover.
6. Check for any obvious non-ThinkPad alterations. Use good judgment as to the safety of any
non-ThinkPad alterations.
7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or
other liquids, or signs of fire or smoke damage.
8. Check for worn, frayed, or pinched cables.
9. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

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 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 green-wire ground.

Chapter 1. Safety information

– 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.

Chapter 2. Important service information
This chapter introduces following important service information that applies to all machine types supported
by this manual:
• “Strategy for replacing FRUs” on page 19
– “Strategy for replacing a hard disk drive or a solid-state drive” on page 19
– “Important notice for replacing a system board” on page 20
– “How to use error message” on page 20
• “Strategy for replacing FRUs for CTO, special-bid, and standard models” on page 20
– “Product definition” on page 20
– “FRU identification” on page 20
Important:
• If the computer is equipped with both a hard disk drive and an M.2 solid-state drive, do not use the M.2
solid-state drive as a bootable device. The M.2 solid-state drive is designed and developed for “cache”
function purpose only.
• Advise customers to contact the Lenovo® Customer Support Center if they need any assistance in
obtaining or installing any software fixes, drivers, and Unified Extensible Firmware Interface basic
input output system (UEFI BIOS) downloads. Telephone numbers for Lenovo Support are available at:
http://www.lenovo.com/support/phone
• System Disassembly/Reassembly videos that show the FRU removals or replacements for the Lenovo
authorized service technicians are available in the following support site:
http://www.lenovoservicetraining.com/ion/

Strategy for replacing FRUs
Before replacing parts:
Ensure that all software fixes, drivers, and UEFI BIOS downloads are installed before replacing any FRUs
listed in this manual.
After a system board is replaced, ensure that the latest UEFI BIOS is loaded to the system board before
completing the service action.
To download software fixes, drivers, and UEFI BIOS, go to http://www.lenovo.com/ThinkPadDrivers and
follow the instructions on the screen.
Use the following strategy to prevent unnecessary expense for replacing and servicing FRUs:
• If you are instructed to replace a FRU but the replacement does not correct 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
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.
• If an adapter or a device consists of more than one FRU, any of the FRUs might 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.

Strategy for replacing a hard disk drive or a solid-state drive
Always try to run a low-level format before replacing a hard disk drive or a solid-state drive. This will cause
all customer data on the drive 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:
• Do not drop a system board or apply any excessive force to it.
• Avoid rough handling of any kind.
• Avoid bending a system board and hard pushing to prevent cracking at each ball-grid-array (BGA) 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, special-bid, and standard models
This topic provides information about the model types and FRU identification.

Product definition
This topic introduces different model types and how to identify each type.
Dynamic configure-to-order (CTO) model
This model provides the ability for a customer to configure a Lenovo solution from a Web Site, and have this
configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label and
eSupport will load these products as the 4-character MT, 4-character model, and 2-character country code.
The model is “CTO1” and the default country code is “WW” (example: 20AACTO1WW).
Special-bid model
This is a unique configuration that has been negotiated between Lenovo and the customer. A unique machine
type model (MTM) consists of a 4-character MT, a 4-character model, and a numeric 2-character country
code is provided to the customer to place orders (example: 20AA000955). The country code assigned is
numeric and does not designate a specific country or region. The custom model factsheet for the MTM
indicates which country the special bid MTM is set up for. Special-bid offering is not generally announced.
Standard model
Standard models (fixed configuration) are announced and offered to all customers. The MTM portion of the
machine label consists of a 4-character MT, a 4-character model, and an alphabetic 2-character country
code. The country code assigned is alphabetic and represents a designated country or region (example:
20AA0009UK).

FRU identification
Use Lenovo eSupport to identify major FRUs, FRU part numbers, and FRU descriptions for a product at
an MT - serial number level. Examples of major FRUs are hard disk drive, system board, and liquid crystal
display (LCD).
To identify the major FRUs for a product, do the following:

Chapter 2. Important service information

T470p Hardware Maintenance Manual

Chapter 3. General checkout
This chapter introduces following information:
• “What to do first” on page 23
• “Checkout guide” on page 24
• “Power system checkout” on page 26
Before you go to the checkout guide, be sure to read the following important notes.
Important notes:
• Only certified trained personnel should service the computer.
• Before replacing any FRU, read the entire page on removing and replacing FRUs.
• When you replace FRUs, it is recommended use new nylon-coated screws.
• Be extremely careful during such write operations as copying, saving, or formatting. The sequence
of the drives in the computer that you are servicing might have been altered. If you select an incorrect
drive, data or programs might be overwritten.
• Replace a FRU only with another FRU of the correct model. When you replace a FRU, ensure
that the model of the machine and the FRU part number are correct by referring to the web site:
http://www.lenovo.com/serviceparts-lookup
• A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur
for a variety of reasons that have nothing to do with a hardware defect, such as cosmic radiation,
electrostatic discharge, or software errors. Consider replacing a FRU only when a problem recurs. If you
suspect that a FRU is defective, clear the error log and run the test again. If the error does not recur, do
not replace the FRU.
• Be careful not to replace a nondefective FRU.

What to do first
When you return a FRU, you must include the following information in the parts exchange form or parts
return form that you attach to it:
1. Name and phone number of service technician
2. Date of service
3. Date on which the machine failed
4. Date of purchase
5. Failure symptoms, error codes appearing on the display, and beep symptoms
6. Procedure index and page number in which the failing FRU was detected
7. Failing FRU name and part number
8. Machine type, model number, and serial number
9. Customer's name and address
Note: During the warranty period, the customer may be responsible for repair costs if the computer damage
was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper
maintenance by the customer. Following is a list of some common items that are not covered under warranty
and some symptoms that might indicate that the system was subjected to stress beyond normal use.
Before checking problems with the computer, determine whether the damage is covered under the warranty
by referring to the following list:
The following are not covered under warranty:
• LCD panel cracked from the application of excessive force or from being dropped

•
•
•
•
•

Scratched (cosmetic) parts
Distortion, deformation, or discoloration of the cosmetic parts
Plastic parts, latches, pins, or connectors that have been cracked or broken by excessive force
Damage caused by liquid spilled into the system
Damage caused by the improper insertion of a personal-computer card (PC card) or the installation of
an incompatible card
Improper disc insertion or use of an external optical drive
Fuses blown by attachment of a nonsupported device
Forgotten computer password (making the computer unusable)
Sticky keys caused by spilling a liquid onto the keyboard
Use of an incorrect ac power adapter on laptop products

•
•
•
•
•

The following symptoms might indicate damage caused by nonwarranted activities:
• Missing parts might be a symptom of unauthorized service or modification.
• Check for obvious damage to a hard disk drive. If the spindle of a hard disk drive becomes noisy, the hard
disk drive might have been dropped or subject to excessive force.

Checkout guide
Use the following procedures as a guide in identifying and correcting problems with the ThinkPad notebook

Passwords
As many as three passwords may be needed for any ThinkPad notebook computer: the power-on password,
the hard disk password, and the supervisor password.

T470p Hardware Maintenance Manual

If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the
computer is turned on. The computer does not start until the password is entered.
Note: If only a supervisor password is set, the password prompt will not be displayed when the operating
system is started.

Power-on password
A power-on password protects the system from being powered on by an unauthorized person. The
password must be entered before an operating system can be started. For instructions on how to remove
the power-on password, see “How to remove the power-on password” on page 31.

Hard disk password
There are two kinds of hard disk passwords:
• User hard disk password - for the user
• Master hard disk password - for the system administrator, who can use it to get access to the hard disk
even if the user has changed the user hard disk password
Note: There are two modes for the hard disk password: User only and Master + User. The Master + User
mode requires two hard disk passwords; the system administrator enters both in the same operation. The
system administrator then provides the user hard disk password to the system user.
Attention: If the user hard disk password has been forgotten, check whether a master hard disk password
has been set. If it has, it can be used for access to the hard disk drive. If no master hard disk password is
available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either
the user or the master hard disk password, or to recover data from the hard disk drive. The hard disk drive
can be replaced for a scheduled fee.
For how to remove the hard disk password, see “How to remove the hard disk password” on page 32.

Supervisor password
The supervisor password protects the system information stored in the ThinkPad Setup program. It provides
the following security features:
• If only a supervisor password is set, a password prompt is displayed when you try to start the ThinkPad
Setup program. Unauthorized users cannot change most of the system configuration options in the
ThinkPad Setup program without the password.
• The system administrator can use the supervisor password to access a computer even if the user of that
computer has set a power-on password. The supervisor password overrides the power-on password.
• The system administrator can set the same supervisor password on many ThinkPad notebook computers
to make administration easier.
Attention: If the supervisor password has been forgotten and cannot be made available to the service
technician, 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 power-on password, do the following:
If no supervisor password has been set, do the following to remove the power-on password:
1. Turn off the computer.

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.If the LCD you are servicing has
two or less visible defective pixels, it should not be considered faulty. However, if the LCD has three or more
visible defective pixels, it will be deemed as defective by Lenovo and it should be replaced.
Notes:
• This policy applies to all ThinkPad notebooks purchased on 1 January, 2008 or later.
• Lenovo will not provide warranty replacement if the LCD is within specifications because we cannot
guarantee that any replacement LCD will have zero pixel defects.
• One pixel consists of R, G, B sub-pixels.

180 degrees more

(Cross-section)

Notes:
• Ensure that you use the correct screw. It is recommended to use new screws for replacements. If you
have a torque screwdriver, tighten all screws firmly to the torque specified in the screw information
table for each step.
• Ensure that torque screwdrivers are calibrated correctly following country specifications.

Retaining serial numbers
This topic provides instructions on the following:
• “Restoring the serial number of the system unit” on page 54
• “Retaining the UUID” on page 55

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.
The serial number of the system unit is written on the label attached to the bottom of the computer.
If you cannot find the serial number of the system unit on the bottom of the computer, try the following
method to get the number:
Note: Before you perform the operation, ensure that the UEFI/Legacy setting within the Startup menu in
the ThinkPad Setup program is set to UEFI Only.
1. Connect a USB memory key to the computer.
2. Go to http://www.lenovo.com/maintenanceutilities and follow the instructions on the screen to create a
Maintenance Key.
Note: Only an authorized Lenovo service technician can access the above Web site.
3. Restart the computer.
4. When the logo is displayed, press Esc. The ThinkPad Config Information Update Utility interface is
displayed.
5. Type 1 under Enter the action desired, then press Enter. The ThinkPad Serial Number Update Utility for
Asset ID screen is displayed.
6. Type 2 under Enter the action desired, then press Enter. The serial number of each device in your
computer is displayed; the serial number of the system unit is listed as follows:
20- Serial number
7. Record the serial number of the system unit.
After you replace the system board, do the following to restore the serial number of the system unit:
1. Connect the Maintenance Key to the computer.

T470p Hardware Maintenance Manual

2. When the logo is displayed, press Esc. The ThinkPad Config Information Update Utility interface is
displayed.
3. Type 1 under Enter the action desired, then press Enter. The ThinkPad Serial Number Update Utility for
Asset ID screen is displayed.
4. Type 1 under Enter the action desired, then press Enter. Then follow the instructions on the screen
to restore the serial number of the system unit.

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, perform the following steps to create a new UUID for the system
board if the system board does not have a UUID:
Note: Before you perform the operation, ensure that the UEFI/Legacy setting within the Startup menu in
the ThinkPad Setup program is set to UEFI Only.
1. Connect a USB memory key to the computer.
2. Go to http://www.lenovo.com/maintenanceutilities and follow the instructions on the screen to create a
Maintenance Key.
Note: Only an authorized Lenovo service technician can access the above Web site.
3. Restart the computer.
4. When the logo screen is displayed, press Esc. The ThinkPad Config Information Update Utility interface
is displayed.
5. Type 2 under Enter the action desired, then press Enter. The Auto UUID generation utility interface is
displayed.
6. Type y under Change UUID. OK? [Y/N], then press Enter. 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) is 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 LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key.
1. Insert the latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key,
and then restart the computer.
2. From the main menu, select 6. Set ECA Information.
3. To read the ECA information, select 2. Read ECA/rework number from EEPROM and follow the
instructions on the screen; To read box build date, select 5. Read box build date from EEPROM, and
follow the instructions 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 latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance
Key to update the EEPROM.
Note: Only the ECA number is stored in the EEPROM. The machine type of the ECA is assumed to be the
same as the machine type of the machine that had the ECA applied to it.
Chapter 7. FRU replacement notices

1. Insert the latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key,
and then restart the computer.
2. From the main menu, select 6. Set ECA Information.
3. To write the ECA information, select 1. Write ECA/rework number from EEPROM, and follow the
instruction; 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.

1160 System board
Important notices for handling the system board
When handling the system board, read the following:
• The system board has an accelerometer, which can be broken when several thousands of G-forces
are applied.
Note: Dropping a system board from a height of as little as 6 inches so that it falls flat on a hard bench
can subject the accelerometer to as much as 6000 G's of shock.
• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or
composite.
• Avoid rough handling of any kind.
• At every point in the process, be sure not to drop or stack the system board.
• If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or a
corrugated conductive material.
For access, remove these FRUs in order:
