Hardware Maintenance Manual

Chapter 1. Safety information
This chapter presents the 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 3
• “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. Ensure 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, ensure 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. Ensure 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, because 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. That 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.
CAUTION:
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:
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
– Units similar to those 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.

Hardware Maintenance Manual

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.
Consider these conditions and the safety hazards they present:
• Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal
electrical shock)
• Explosive hazards, such as a damaged CRT face or a bulging capacitor
• Mechanical hazards, such as loose or missing hardware
To determine whether there are any 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. Ensure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

Chapter 1. Safety information

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.
– 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 presents the 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” on page 20
– “Important notice for replacing a system board” on page 20
– “How to use error message” on page 20
• “Strategy for replacing FRUs for CTO, CMV, and GAV” on page 20
– “Product definition” on page 20
– “FRU identification for CTO, CMV, and GAV products” on page 21
Important:
• If the computer is equipped with both a hard disk drive and an mSATA solid-state drive, do not use the
mSATA solid-state drive as a bootable device. The mSATA solid-state drive is used for the “cache”
function only.
• Advise customers to contact the Lenovo® Customer Support Center if they need any assistance in
obtaining or installing any software fixes, drivers, and 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 and install 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 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.

Strategy for replacing a hard disk drive
Always try to run a low-level format operation before replacing a hard disk drive or a solid-state drive. This
will cause all customer data on the hard disk drive or solid-state drive to be lost. Be sure that the customer
has a current backup of the data before you perform this task.
Attention: The drive startup sequence in the computer you are servicing might 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.
If the computer is shipped with both an mSATA solid-state drive and a hard disk drive, the mSATA solid-state
drive is used for the “cache” function and to support the Intel® Rapid Start Technology. We recommend that
users do not replace the mSATA solid-state drive by themselves. Otherwise, the “cache” function will not
work and the Intel Rapid Start Technology cannot be used any more.
Attention: Ensure that you partition the mSATA solid-state drive after installing it on the computer you are
servicing. Otherwise, the mSATA solid-state drive will not function correctly. For instructions on partitioning
the mSATA solid-state drive, go to http://www.lenovo.com/support/msata-fru.

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 might also cause false error
codes. If no error code is displayed, see whether the error symptom is listed in the “Symptom-to-FRU Index”.

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 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) and eSupport 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 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.
• 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).
20

Hardware Maintenance Manual

• The PEW record is the 4-digit MT and 3-digit model, where model = “CTO” (Example: 1829-CTO).
• eSupport will show both the CTO and CMV machine type models (Example: 1829-CTO and 1829-W15
will be found on the eSupport site.)
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 and eSupport 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 and eSupport.
Using PEW
• PEW is the primary source for identifying FRU part numbers and FRU descriptions for the key commodities
for CTO, CMV, and GAV products at an MT - serial number level. An example of key commodities are hard
disk drives, system boards, microprocessors, liquid crystal displays (LCDs), and memory modules.
• 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).
• PEW can be accessed at the following Web site:
http://www.lenovo.com/support/site.wss/document.do?lndocid=LOOK-WARNTY
Select Warranty lookup. Input the MT and the Serial number and the list of key commodities will be
returned in the PEW record under COMPONENT INFORMATION.
Using eSupport
For key commodities (examples - hard disk drive, system board, microprocessor, LCD, and memory)
eSupport can be used to view the warranty status of key commodities built in a particular machine serial (this
is the same record found in PEW). eSupport can be accessed at http://www.lenovo.com/support.
To view the warranty status of the key commodities on your computer, do the following:
1. Go to http://www.lenovo.com/support.
2. Click Warranty & Services.
3. Click Check Warranty Status.
4. On the Warranty Status Lookup page, click Parts Lookup.
5. Type your machine type and serial number, and then click Submit.
For the remaining FRUs (the complete list of FRUs at the MT model level)
eSupport also can be used to view the complete list of FRUs for a machine type and model. To view the
complete list of FRUs, do the following:
1. Go to http://www.lenovo.com/support.
2. Click Parts & Accessories.
3. Provide your product information or click Launch to automatically identify your product.
4. Click Product & Parts Detail.
5. On the PRODUCT AND PARTS DETAIL page, click Parts Detail to view the complete list of FRUs.

Chapter 3. General checkout
This chapter presents the following information:
• “What to do first” on page 23
• “Checkout guide” on page 24
• “Power system checkout” on page 26
Some descriptions in this chapter might not apply to your particular computer.
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 or replacing FRUs.
• When you replace FRUs, it is recommended to use new nylon-coated screws.
• Be extremely careful during such write operations as copying, saving, or formatting. Drives in the computer
that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs
might be overwritten.
• Replace 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. For the FRU part number, go to
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 do 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 subject 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

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 notebook computers purchased on 1 January, 2008 or later.
•

Lenovo will not provide replacement if the LCD is within specification as we cannot guarantee that
any replacement LCD will have zero pixel defects.

Screw notices
Loose screws can cause a reliability problem. In the ThinkPad notebook computer, this problem is addressed
with special nylon-coated screws that have the following characteristics:
• They maintain tight connections.
• They do not easily come loose, even with shock or vibration.
• They are harder to tighten.
Do the following when you service this machine:
• Keep the screw kit in your tool bag. For the part number of the screw kit, go to
http://www.lenovo.com/serviceparts-lookup.
• It is recommended to use new screws.
• It is recommended to use each screw only once.
• Use a torque screwdriver if you have one.
Tighten screws as follows:
• Plastic to plastic
Turn an additional 90 degrees after the screw head touches the surface of the plastic part:

• Logic card to plastic
Turn an additional 180 degrees after the screw head touches the surface of the logic card:

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 torque screwdrivers are calibrated correctly following country specifications.

Retaining serial numbers
This section includes the following descriptions:
•
•
•

“Restoring the serial number of the system unit” on page 52
“Retaining the UUID” on page 53
“Reading or writing the ECA information” on page 53

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 ThinkPad Hardware Maintenance Diskette Version 1.76 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 the system unit is listed as: 20:
Serial number.
4. Write down that number.
Note: The serial number of the system unit also is 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 ThinkPad Hardware Maintenance Diskette Version 1.76 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.
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 the following example:

Hardware Maintenance Manual

MTM on the rear label:
TTTT-CTO S/N SSSSSSS
Product ID on the 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.
When you replace the system board, you must set the UUID on the new system board as follows:
1. Install the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 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.
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 Version 1.76 or later.
1. Insert the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later, and 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.
4. To read the 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 LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later 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.
1. Insert the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later, and 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
instructions on the screen.
4. To write the box build date, select 4. Write box build date from EEPROM, and follow the instructions
on the screen.

Chapter 8. FRU replacement notices

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.

Hardware Maintenance Manual

Chapter 9. Removing or replacing a FRU
This chapter provides instructions on how to remove or replace a FRU.

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 8 “FRU replacement notices” on page 51.
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 procedure. 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 drawings by the numbers
in square callouts.
5. When turning a screw, turn it in the direction as given by the arrow in the drawing.
6. When removing a 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.
8. When replacing a FRU, use the correct screw(s) as shown in the replacement procedure.
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.

Before servicing the computer
Removing the SIM card
Depending on the model, the computer you are servicing might have a SIM card slot. If the customer has
installed a SIM card in the slot, remove it before servicing.
To remove the SIM card, you need to remove the battery pack first. See “1010 Battery pack” on page 56.

After you finish the servicing, ensure that you insert the card back into the slot firmly.

1010 Battery pack
Important notice for replacing a battery pack:
• 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 in the computer, the customer should download this program
before a non-physically damaged battery pack is replaced. Note that the replacement of a physically damaged
battery pack is not covered by the warranty.

Removal steps of mSATA solid-state drive
The computer comes with either a PCI Express Mini Card for wireless WAN or an mSATA solid-state drive. If
the computer is equipped with an mSATA solid-state drive, it is installed in the wireless WAN card slot.
Attention:
• Do not drop the drive or apply any physical shock to it. The drive is sensitive to physical shock. Improper
handling can cause damage and permanent loss of data.
• Before removing the drive, have the user make a backup copy of all the information on it if possible.
• Never remove the drive while the computer is operating or in suspend mode.
• Ensure that you partition the mSATA solid-state drive after installing it on the computer you are servicing.
Otherwise, the mSATA solid-state drive will not function correctly. For instructions on on how to partition

1140 Systemboard, DC-in connector, thermal fan assembly, and
ExpressCard slot
Important notices for handling the system board:
When handling the system board, bear the following in mind:
• The system board has an accelerometer, which can be broken if 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 6,000 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.
• If a system board is dropped, be sure to document the drop in any reject report, and replace the system board.
• 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 surface.
