ThinkPad X1 Tablet Hardware Maintenance Manual

Chapter 1. Safety information
This chapter presents following safety information that you should be familiar with before you service
a ThinkPad tablet 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. 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 working in conditions that might be hazardous to your eyes. The
conditions include hammering, drilling, soldering, cutting wire, attaching springs, using solvents, and
so on.
• 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 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, disconnect the power cord. 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 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.

ThinkPad X1 Tablet 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. Turn off the tablet.
3. Disable the built-in battery. For the instruction on how to disable the built-in battery, see “Disabling the
built-in battery” on page 50.
4. Disconnect the power cord.
5. Check the power cord 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. Ensure that the continuity between the external ground pin and the
frame ground is 0.1 ohm or less.
b. The power cord 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 built-in 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 built-in 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.

Chapter 1. Safety information

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.
– 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.

• Service training documents, for example the videos that show the FRU removals or replacements, are
provided to Lenovo authorized service technicians. The training documents are available at:
http://www.lenovoservicetraining.com

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/ThinkPad Drivers and
follow the instructions on the screen.
• 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 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 tablet you are servicing.

Strategy for replacing FRUs for CTO, special bid model, 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)
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 model is a unique configuration that has been negotiated between Lenovo and the customer. A unique
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).

Message: Error: The System UEFI Variable Storage is
nearly full.
Note:
This error indicates that the operating system or
applications cannot create, modify, or delete data in
the non-volatile system UEFI variable storage due to
insufficient storage space after POST.

Enter ThinkPad Tablet Setup after the error message is
displayed. A dialog asks the user for confirmation to
clean up the storage. If the user selects Yes, all data that
were created by the operating system or applications are
deleted except global variables defined by the Unified
Extensible Firmware Interface Specification. If the user
selects No, all data is kept, but the operating system or
applications will not be able to create, modify, or delete
data in the storage.

The non-volatile system UEFI variable storage is used
by the UEFI BIOS and by the operating system or
applications. This error occurs when the operating system
or applications store large amounts of data in the variable
storage. All data needed for POST, such as BIOS setup
settings, chipset or platform configuration data, are stored
in a separate UEFI variable storage.

If this error happens at a service center, Lenovo authorized
service personnel will clean up the non-volatile system
UEFI variable storage using the above solution.

Intermittent problems
Intermittent system hang problems can be due to a variety of causes that have nothing to do with a hardware
defect, such as cosmic radiation, electrostatic discharge, or software errors. FRU replacement should be
considered only when a problem recurs.
When analyzing an intermittent problem, do the following:
1. Run the diagnostic test for the system board in loop mode at least 10 times.
2. If no error is detected, do not replace any FRUs.
3. If any error is detected, replace the FRU shown by the FRU code. Rerun the test to verify that no
more errors exist.

Undetermined problems
If the diagnostic tests did not identify the adapter or device that has failed, if wrong devices are installed,
or if the system simply is not operating, follow these procedures to isolate the failing FRU (do not isolate
FRUs that have no defects).

Chapter 4. Related service information
