Hardware Maintenance Manual

Chapter 1. Safety information
This chapter presents following safety information that you need to be familiar with before you service a
Lenovo 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 tool case 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 non-conductive 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,
non-grounded 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-Lenovo features or options not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent hazard could be and
whether you can continue without first correcting the problem.

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.
c. Insulation must not be frayed or worn.
4. Check for cracked or bulging batteries.
5. Remove the cover.
6. Check for any obvious non-Lenovo alterations. Use good judgment as to the safety of any non-Lenovo
alterations.
7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or
other liquids, or signs of fire or smoke damage.
8. Check for worn, frayed, or pinched cables.
9. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

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.
– 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.
Chapter 1. Safety information

– 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
– “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://support.lenovo.com/en_US/downloads/detail.page?LegacyDocID=DRVR-MATRIX 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.

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, liquid crystal display

Chapter 3. General checkout
This chapter introduces following information:
• “What to do first” on page 21
• “Power system checkout” on page 22
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, carefully remove and retain screws so they can be reused.
• 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 FRU parts list.
• 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 non-supported 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 non-warranted 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.

Power system checkout
To verify if a battery pack or an ac power adapter is functional, do the following:
1. Turn off the computer.
2. Connect the ac power adapter.
3. Turn on the computer. If the computer can be turned on, it means that either the battery pack or the ac
power adapter is functional.
4. Insert a straightened paper clip into the novo button to reset the computer. If the computer is still
powered on, it means that the ac power adapter is functional.
5. Turn off the computer.
6. Disconnect the ac power adapter and turn on the computer. If the computer can be turned on, it
means that the battery pack is functional.
If you suspect a power problem, see the appropriate one of the following power supply checkouts:
• “Checking the ac power adapter” on page 22
• “Checking the external battery pack and the operational charging” on page 23

Checking the ac power adapter
You are here because the computer fails only when the ac power adapter is used.
• If the power problem occurs only when the docking station or the port replicator is used, replace the
docking station or the port replicator.
• If the power-on indicator does not turn on, check the power cord of the AC adapter for correct continuity
and installation.
• If the computer does not charge during operation, go to “Checking the external battery pack and the
operational charging” on page 23.
To check the ac power adapter, do the following:
1. Unplug the ac power adapter cable from the computer.
2. Measure the output voltage at the plug of the ac power adapter cable. See the following illustration:

hard disk password (HDP), and the administrator password.
If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is
turned on. The computer does not start until the password is entered.

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

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.

Administrator password
Administrator password controls the access of the whole setup utility. Only Administrator password was set
then User password can be set. If Administrator password was cleared, the User password was cleared too.
Attention: If the administrator 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.

Chapter 8. Locations
This chapter introduces the locations of the hardware components on your computer.

Locating FRUs and CRUs
This topic introduces the following service parts:
• “Major FRUs and CRUs” on page 34
• “LCD FRUs” on page 38
• “Miscellaneous parts and other FRUs” on page 39

Notes:
• Each FRU is available for all types or models, unless otherwise specified.
• CRU statement for customers:
You can resolve some problems with your product with a replacement part you can install yourself, called a
“Customer Replaceable Unit” or “CRU.” Some CRUs are designated as self-service CRUs and others are
designated as optional-service CRUs. Installation of self-service CRUs is your responsibility. For optional-service
CRUs, you can either install the CRU yourself or you can request that a Service Provider install the CRU according
to the warranty service for your product. If you intend on installing the CRU, Lenovo will ship the CRU to you. CRU
information and replacement instructions are shipped with your product and are available from Lenovo at any time
upon request. You can find a list of CRUs for your product in this Hardware Maintenance Manual. An electronic
version of this manual can be found at http://www.lenovo.com/UserManuals. Follow the on-screen instructions
to find the manual for your product. You might be required to return the defective part that is replaced by the
CRU. When return is required: (1) return instructions, a prepaid shipping label, and a container will be included
with the replacement CRU; and (2) you might be charged for the replacement CRU if Lenovo does not receive the
defective CRU within thirty (30) days of your receipt of the replacement CRU. See your Lenovo Limited Warranty
documentation for full details.
Lenovo 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 the ac power adapter, power cord, and battery. Other self-service CRUs depending on product
design might include the memory module, wireless card, keyboard, and palm rest with finger print reader and
touch pad.
– 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.

Hardware Maintenance Manual

Chapter 9. FRU replacement notices
This chapter presents notices related to removing and replacing parts. Read this chapter carefully before
replacing any FRU.
CRU statement for customers:
You can resolve some problems with your product with a replacement part you can install yourself, called
a “Customer Replaceable Unit” or “CRU.” Some CRUs are designated as self-service CRUs and others
are designated as optional-service CRUs. Installation of self-service CRUs is your responsibility. For
optional-service CRUs, you can either install the CRU yourself or you can request that a Service Provider
install the CRU according to the warranty service for your product. If you intend on installing the CRU,
Lenovo will ship the CRU to you. CRU information and replacement instructions are shipped with your
product and are available from Lenovo at any time upon request. You can find a list of CRUs for your
product in this Hardware Maintenance Manual. An electronic version of this manual can be found at
http://www.lenovo.com/UserManuals. Follow the on-screen instructions to find the manual for your product.
You might be required to return the defective part that is replaced by the CRU. When return is required: (1)
return instructions, a prepaid shipping label, and a container will be included with the replacement CRU; and
(2) you might be charged for the replacement CRU if Lenovo does not receive the defective CRU within thirty
(30) days of your receipt of the replacement CRU. See your Lenovo Limited Warranty documentation for
full details.

Note: The illustrations used in this section are of the Lenovo E41, unless otherwise stated.

General guidelines
When removing or replacing a FRU, be sure to observe the following general guidelines:
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 Chapter 9 “FRU replacement notices” on page 47.
3. Begin by removing any FRUs that have to be removed before replacing the failing FRU. Any such FRUs
are listed at the beginning of each FRU replacement section. Remove them in the order in which they
are listed.
4. Follow the correct sequence in the steps for removing a FRU, as given in the illustrations by the
numbers in square callouts.
5. When turning a screw, turn it in the direction as given by the arrow in the illustration.
6. When removing a FRU, move it in the direction as given by the arrow in the illustration.
7. To put the new FRU in place, reverse the removal procedure and follow any notes that pertain to
replacement.
8. When replacing a FRU, use the correct screws as shown in the replacement procedures.
DANGER
Before removing any FRU, turn off the computer, unplug all power cords from electrical outlets, 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 (ESD).
Before touching it, establish personal grounding by touching a ground point with one hand or by using an
electrostatic discharge strap.

1010 External battery pack
Important notices for replacing a battery pack
Attention: Lenovo has no responsibility for the performance or safety of unauthorized batteries, and
provides no warranties for failures or damage arising out of their use.
The Lenovo Solution Center program provides an automatic battery diagnostic test that determines if the
battery pack is defective. A battery pack FRU should not be replaced unless this diagnostic test shows
that the battery is defective. The only exception to this is if the battery pack is physically damaged or a
customer is reporting a possible safety issue.
If the Lenovo Solution Center program is not installed on the computer, the customer should download and
install the program to diagnose the battery pack, before getting a non-physically damaged battery pack
replaced. Note that the replacement of a physically damaged battery pack is not covered by the warranty.
Removal steps of the external battery pack
DANGER
Use only the authorized battery specified for your computer. Any other battery could ignite or
explode.
