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 other parts that you have removed.
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 disconnect the micro-USB cable 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, disconnect the micro-USB cable. If you cannot unplug it, power
off the wall box that supplies power to the machine, and 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
– Motor generators
– Similar units to 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.
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 micro-USB cable disconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Turn off the tablet.
3. Disconnect the power supply of the internal battery by pressing the emergency reset button inside the
emergency reset hole using a straightened paper clip.
4. Disconnect the micro-USB cable.
5. Check the micro-USB cable for the following:
a. Make sure that a third-wire ground connector is in good condition. Use a meter to measure the
third-wire ground continuity, and make sure that the continuity between the external ground pin and
the frame ground is 0.1 ohm or less.
b. The micro-USB cable is the type specified in the parts list.
c. Insulation is not frayed or worn.
6. Remove the LCD module assembly.
7. Check for cracked or bulging internal batteries.
8. Check for any obvious non-ThinkPad alterations. Use good judgment as to the safety of any
non-ThinkPad alterations.
9. 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.
10. Check for worn, frayed, or pinched cables.
11. Check that the internal battery fasteners (screws or rivets) have not been removed or tampered with.
Handling devices that are sensitive to electrostatic discharge
Any tablet 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:
Chapter 1. Safety information

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.
– Use the round ground prong of the ac plug on ac-operated tablets.
Grounding requirements
Electrical grounding of the tablet is required for operator safety and correct system function. Proper
grounding of the electrical outlet can be verified by a certified electrician.

Telephone numbers for Lenovo Support Center are available at:
• System disassembly and reassembly videos that show the FRU removal and replacement procedures for
the Lenovo authorized service technicians are available at:
Strategy for replacing FRUs
Before replacing parts:
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 tablets 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.
Attention: The setup configuration on the tablet 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.
Important notice for replacing a system board
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 BGA (Ball Grid Array) chipset.

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), eSupport, and the HMM will load these products as the 4-digit MT
and 3-digit model, where model = “CTO” (Example: 1829-CTO).
Custom Model Variant (CMV)
This is a unique configuration that has been negotiated between 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).
• 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.)
• The HMM will have the 4-digit MT and 3-digit CTO model only (Example: 1829-CTO). Again, CMVs are
custom models and are not found in the HMM.
General Announce Variant (GAV)
This is a standard model (fixed configuration). GAVs are announced and offered to all customers. The MTM
portion of the machine label is a 4-digit MT and 3-digit model, where model = a “fixed part number”, not
“CTO” (Example: 1829-F1U). Also, PEW, eSupport, and the HMM will list these products under the same
fixed model number.
FRU identification for CTO, CMV, and GAV products
There are three information resources to identify which FRUs are used to support CTO, CMV, and GAV
products. These sources are PEW, eSupport, and the HMM.
Using PEW
• PEW is the primary source for identifying FRU part numbers and FRU descriptions for the key
commodities for CTO, CMV and GAV products at a MT - serial number level. An example of key
commodities are system boards and Liquid Crystal Displays (LCDs).
• 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:
Select Warranty lookup. Input the machine type 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 - system board and LCD)

• 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).
• eSupport can be accessed at the following Web site:
• To view the key commodities, do the following:
1. Click Products & Service Warranty.
2. Click Check Warranty Status.
3. On the Warranty Status Lookup page, click Parts Lookup.
4. Type your machine type and serial number, and then click Submit. The key commodities will be
displayed.
For the remaining FRUs (the complete list of FRUs at the MT model level)
• eSupport 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. Click Product & Parts Detail and then follow the instructions on the screen to reach the Product
and Parts Details page.
2. Click the Parts Detail tab to view the list of service parts.
Using the HMM
For key commodities (examples - system board and LCD)
Use the HMM as a backup to PEW and eSupport to view the complete list of FRUs at the MT model level.

This chapter presents the following information:
•
•
Diagnostics: Instructions for accessing and using system resident service diagnostics can be found at the
following Web site:
Note: To access and use the diagnostics, you must have a valid login ID and password.
Important:
• 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, use new nylon-coated screws.
• Be extremely careful during such write operations as copying, saving, or formatting.
• Replace a FRU only with another FRU of the correct model.
When you replace a FRU, make sure 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 non-defective 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. Failing FRU name and part number
6. Machine type, model number, and serial number
7. Customer's name and address
Note: During the warranty period, the customer may be responsible for repair costs if the tablet 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 tablet, determine whether the damage is covered under the warranty by

Chapter 6. FRU replacement notices
External CRU statement to customers:
Some problems with your product can be resolved 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; you may
request that Lenovo installs an Optional-service CRU according to the warranty service for your product.
Where you are 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 may
find a list of CRUs in the publications that ship with your product or at http://www.lenovo.com/CRUs. You
may 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
may be charged for the replacement CRU if Lenovo does not receive the defective part within thirty (30) days
of your receipt of the replacement CRU. See your Lenovo Limited Warranty documentation for full details.
This chapter presents notices related to removing and replacing parts. Read this chapter carefully before
replacing any FRU.
Screw notices
Loose screws can cause a reliability problem. In a ThinkPad Tablet, 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.
• Each one should be used only once.
Do the following when you service the tablet:
• Keep the screw kit in your tool bag. For the part number (P/N) of the screw kit, see “Miscellaneous
• Always use new screws.
• Use a torque screwdriver if you have one.
Tighten screws as follows:
• Plastic to plastic
Turn an additional angle of 90 degrees after the screw head touches the surface of the plastic part.
• Logic card to plastic
Turn an additional angle of 180 degrees after the screw head touches the surface of the logic card.

Notes:
• 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 for each step in Chapter 7 “Removing and replacing a FRU” on page 35. Never
use a screw that you removed. Use a new one. Make sure that all of the screws are tightened firmly.
• Ensure torque screwdrivers are calibrated correctly following country specifications.

This chapter 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 tablet unless you have been trained and certified. An untrained person runs
the risk of damaging parts.
3. Begin by removing any FRUs that have to be removed before replacing the failing FRU. Any such FRUs
are listed at the top of each FRU replacement page. 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 to replace a FRU, 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. For information about connecting and arranging internal cables, see Chapter 8 “Locating
8. When replacing a FRU, use the correct screw(s) as shown in the procedures.
DANGER
Before removing any FRU, turn off the tablet, disconnect all power supplies, remove the internal
battery, and then disconnect any interconnecting cable.
Attention: After replacing a FRU, do not turn on the tablet until you have made sure that all screws, springs,
and other small parts are in place and none are loose inside the tablet. Verify this by shaking the tablet 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).
Before servicing the ThinkPad Tablet
Some models of the ThinkPad Tablet you are servicing might have the SIM card that the customer has
installed.
If the tablet you are servicing has the SIM card, remove it before you start the servicing.

CRU; two asterisks (**) means that the part is an Optional-service CRU.
External CRU statement to customers:
Some problems with your product can be resolved 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; you may request
that Lenovo installs an Optional-service CRU according to the warranty service for your product. Where you are
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 may find a list of CRUs in the
publications that ship with your product or at http://www.lenovo.com/CRUs. You may 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 may be charged for the replacement CRU if
Lenovo does not receive the defective part within thirty (30) days of your receipt of the replacement CRU. See your
Lenovo Limited Warranty documentation for full details.
A ThinkPad Tablet contains 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 charger and micro-USB cable. Other Self-service CRUs depending on product design
might include the wireless card and ThnkPad Tablet Keyboard Folio Case.
– Optional-service CRUs: These CRUs are isolated parts within the tablet 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.
• FRUs marked with OP are available as options.
