Chapter 1. Safety information

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

General safety Follow these rules to ensure general safety: Observe good housekeeping in the area of the machines during and after maintenance. When lifting any heavy object:

1. Make sure that you can stand safely without slipping.

2. Distribute the weight of the object equally between your feet.

3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.

4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Do not attempt to lift any object that weighs more than 16 kg (35 lb) or that you think is too heavy for you.

Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe. Before you start the machine, make sure that other service technicians and the customer's personnel are

not in a hazardous position. Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the

machine. Keep your toolcase away from walk areas so that other people will not trip over it. Do not wear loose clothing that can be trapped in the moving parts of a machine. Make sure that your

sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it. Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, about 8

centimeters (3 inches) from the end. Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.

Attention: Metal objects are good electrical conductors. Wear safety glasses when you are hammering, drilling, soldering, cutting wire, attaching springs, using

solvents, or working in any other conditions that might be hazardous to your eyes. After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that

is worn or defective. Reinstall all covers correctly before returning the machine to the customer. Fan louvers on the machine help to prevent overheating of internal components. Do not obstruct fan

louvers or cover them with labels or stickers.

Electrical safety Observe the following rules when working on electrical equipment.

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

Copyright Lenovo 2019 1

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 have to work on a machine that has exposed electrical circuits, observe the following precautions: Ensure that another person, familiar with the power-off controls, is near you.

Attention: Another person must be there to switch off the power, if necessary. Use only one hand when working with powered-on electrical equipment; keep the other hand in your

pocket or behind your back.

Attention: An electrical shock can occur only when there is a complete circuit. By observing the above rule, you may prevent a current from passing through your body.

When using testers, set the controls correctly and use the approved probe leads and accessories for that tester.

Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages; Instructions for these precautions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

Regularly inspect and maintain your electrical hand tools for safe operational condition. Do not use worn or broken tools and testers. Never assume that power has been disconnected from a circuit. First, check that it has been powered off. Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors,

nongrounded power extension cables, power surges, and missing safety grounds. Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is

conductive; such touching can cause personal injury and machine damage. Do not service the following parts with the power on when they are removed from their normal operating

places in a machine: Power supply units Pumps Blowers and fans Motor generators Similar units as listed above This practice ensures correct grounding of the units.

If an electrical accident occurs: Use caution; do not become a victim yourself. Switch off power. Send another person to get medical aid.

Safety inspection guide The purpose of this inspection guide is to assist you in identifying potentially unsafe conditions. As each machine was designed and built, required safety items were installed to protect users and service technicians from injury. This guide addresses only those items. You should use good judgment to identify potential safety hazards due to attachment of non-ThinkPad features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

2 P1 Gen 2, X1 Extreme and X1 Extreme 2nd 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 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: https://

support.lenovo.com/partslookup

c. Insulation must not be frayed or worn.

4. Check for cracked or bulging batteries. 5. Remove the cover. 6. Check for any obvious non-ThinkPad alterations. Use good judgment as to the safety of any non-

ThinkPad alterations. 7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or

other liquids, or signs of fire or smoke damage. 8. Check for worn, frayed, or pinched cables.

9. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling devices that are sensitive to electrostatic discharge Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD.) ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.

Notes: 1. Use product-specific ESD procedures when they exceed the requirements noted here.

2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts: Keep the parts in protective packages until they are inserted into the product. Avoid contact with other people. Wear a grounded wrist strap against your skin to eliminate static on your body. Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when

you are wearing a wrist strap. Use a grounded work mat to provide a static-free work surface. The mat is especially useful when

handling ESD-sensitive devices. Select a grounding system, such as those listed below, to provide protection that meets the specific

service requirement.

Note: The use of a grounding system to guard against ESD damage is desirable but not necessary. Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.

Chapter 1. Safety information 3

When working on a double-insulated or battery-operated system, use an ESD common ground or reference point. You can use coax or connector-outside shells on these systems.

Use the round ground prong of the ac plug on ac-operated computers.

Grounding requirements Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.

Chapter 2. Important service information

This chapter introduces following important service information that applies to all machine types supported by this manual: Strategy for replacing FRUs on page 21

Strategy for replacing an M.2 solid-state drive on page 21 Important notice for replacing a system board on page 22 How to use error message on page 22

Strategy for replacing FRUs for CTO, special-bid, and standard models on page 22 Product definition on page 22 FRU identification on page 22

Important: Advise customers to contact the Lenovo Support Web site at http://www.lenovo.com/support to view

the software fixes, download the drivers, and follow the on-screen instructions to install the drivers. For additional assistance, customers might call the Lenovo Customer Support Center. Telephone numbers for the Lenovo Support Center are available at: https://pcsupport.lenovo.com/supportphonelist

Service training documents for Lenovo authorized service technicians are available at the following Web site. The disassembly and reassembly videos that show the FRU removal and replacement procedures are contained in the documents. https://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 https://support.lenovo.com 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 an M.2 solid-state drive Always try to run a low-level format before replacing an M.2 solid-state drive (SSD). This will cause all customer data on the M.2 SSD to be lost. Be sure that the customer has a current backup of the data before doing this task.

Copyright Lenovo 2019 21

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 damage 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 BGA (Ball Grid Array)

chipset.

How to use error message Use the error codes displayed on the screen to diagnose failures. If more than one error code is displayed, begin the diagnosis with the first error code. Whatever causes the first error code may also cause false error codes. If no error code is displayed, see whether the error symptom is listed in the Symptom-to-FRU Index for the computer you are servicing.

Strategy for replacing FRUs for CTO, special-bid, and standard models This topic provides information about the model types and FRU identification.

Product definition This topic introduces different model types and how to identify each type.

Dynamic configure-to-order (CTO) model

This model provides the ability for a customer to configure a Lenovo solution from a Web site, and have this configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label and eSupport will load these products as the 4-character MT, 4-character model, and 2-character country code. The model is CTO1 and the default country code is WW (example: 20A7CTO1WW).

Special-bid model

This is a unique configuration that has been negotiated between Lenovo and the customer. A unique machine type model (MTM) consists of a 4-character MT, a 4-character model, and a numeric 2-character country code is provided to the customer to place orders (example: 20A7000955). 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: 20A70009UK).

FRU identification To identify FRUs for a product, do the following:

1. Go to https://support.lenovo.com/partslookup.

22 P1 Gen 2, X1 Extreme and X1 Extreme 2nd Hardware Maintenance Manual

2. Type the Machine Type in the corresponding field to get a general FRU list. Or type the Serial Number for more detailed FRU information.

Chapter 3. General checkout

This chapter introduces following information: What to do first on page 25 Checkout guide on page 26

Diagnosing problems on page 26 Quick test programs on page 27 UEFI diagnostic program on page 27 Bootable diagnostic programs on page 27

Power system checkout on page 28

Before you go to the checkout guide, be sure to read the following important notes.

Important notes: Only certified trained personnel should service the computer. Before replacing any FRU, read the entire page on removing and replacing FRUs. When you replace FRUs, it is recommended use new nylon-coated screws. Be extremely careful during such write operations as copying, saving, or formatting. The sequence

of the drives in the computer that you are servicing might have been altered. If you select an incorrect drive, data or programs might be overwritten.

Replace a FRU only with another FRU of the correct model. When you replace a FRU, ensure that the model of the machine and the FRU part number are correct by referring to the Web site: https:// support.lenovo.com/partslookup

A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for various 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.

Copyright Lenovo 2019 25

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 PC card or the installation of an incompatible card Improper disc insertion or use of an optical drive Fuses blown by attachment of a nonsupported device Forgotten computer password (making the computer unusable) Sticky keys caused by spilling a liquid onto the keyboard Use of an incorrect ac power adapter on laptop products

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

disk drive might have been dropped or subject to excessive force.

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

Note: The diagnostic tests are intended to test only ThinkPad products. The use of non-ThinkPad products, prototype cards, or modified options can lead to false indications of errors and invalid system responses.

1. Identify the failing symptoms in as much detail as possible. 2. Verify the symptoms. Try to re-create the failure by running the diagnostic test or by repeating the

operation.

Diagnosing problems Many computer problems can be solved without outside assistance. If you experience a problem with your computer, the first place to start is the troubleshooting information in your computer documentation. If you suspect a software problem, see the documentation, including readme files and help information systems, that come with the operating system or program.

Note: If you are unable to isolate and repair the problem yourself after running Lenovo Companion, save and print the log files created by the program. You need the log files when you speak to a Lenovo technical support representative.

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

If any of these passwords has been set, a prompt for it will be displayed on the screen whenever the computer is turned on. The computer does not start until the password is entered.

Note: If only a supervisor password is set, the password prompt will not be displayed when the operating system is started.

Power-on password A power-on password protects the system from being powered on by an unauthorized person. The password must be entered before an operating system can be started. For instructions on how to remove the power-on password, see How to remove the power-on password on page 34.

Hard disk password There are two kinds of hard disk passwords: User hard disk password - for the user Master hard disk password - for the system administrator, who can use it to get access to the hard disk

even if the user has changed the user hard disk password

Note: There are two modes for the hard disk password: User only and Master + User. The Master + User mode requires two hard disk passwords; the system administrator enters both in the same operation. The system administrator then provides the user hard disk password to the system user.

Attention: If the user hard disk password has been forgotten, check whether a master hard disk password has been set. If it has, it can be used for access to the hard disk drive. If no master hard disk password is available, neither Lenovo nor Lenovo authorized service technicians provide any services to reset either the user or the master hard disk password, or to recover data from the hard disk drive. The hard disk drive can be replaced for a scheduled fee.

For how to remove the hard disk password, see How to remove the hard disk password on page 35.

Supervisor password The supervisor password protects the system information stored in the ThinkPad Setup program. It provides the following security features:

If only a supervisor password is set, a password prompt is displayed when you try to start the ThinkPad Setup program. Unauthorized users cannot change most of the system configuration options in the ThinkPad Setup program without the password.

The system administrator can use the supervisor password to access a computer even if the user of that computer has set a power-on password. The supervisor password overrides the power-on password.

The system administrator can set the same supervisor password on many ThinkPad notebook computers to make administration easier.

Attention: If the supervisor password has been forgotten and cannot be made available to the service technician, there is no service procedure to reset the password. The system board must be replaced for a scheduled fee.

Chapter 4. Related service information 33

System management password The system management password can also protect the system information stored in UEFI BIOS like a supervisor password, but it has lower authority by default. The system management password can be set through the UEFI BIOS menu or through Windows Management Instrumentation (WMI) with the Lenovo client-management interface.

You can enable the system management password to have the same authority as the supervisor password to control security related features. To customize the authority of the system management password through the UEFI BIOS menu:

1. Enter the UEFI BIOS menu.

Note: When you are prompted by the icon , enter the correct supervisor password if a supervisor password has been set, or enter the correct system management password if no supervisor password has been set. Otherwise, you cannot change the configurations in the following steps.

2. Select Security Password System Management Password Access Control.

3. Follow the on-screen instructions.

If you have set both the supervisor password and the system management password, the supervisor password overrides the system management password. If you have set both the system management password and the power-on password, the system management password overrides the power-on password.

LCD-related symptoms Important: The TFT LCD for the notebook computer contains many thin-film transistors (TFTs). The presence of a small number of dots that are missing, discolored, or always lighted is characteristic of TFT LCD technology, but excessive pixel problems can cause viewing concerns.If the LCD you are servicing has two or less visible defective pixels, it should not be considered faulty. However, if the LCD has three or more visible defective pixels, it will be deemed as defective by Lenovo and it should be replaced.

Notes:

This policy applies to all ThinkPad notebooks purchased on 1 January, 2008 or later.

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

One pixel consists of R, G, B sub-pixels.

When handling the system board, read the following:

The system board has an accelerometer, which can be broken when several thousands of G-forces are applied.

Note: Dropping a system board from a height of as little as six inches so that it falls flat on a hard bench can subject the accelerometer to as much as 6000 G's of shock.

Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or composite.

Avoid rough handling of any kind.

At every point in the process, be sure not to drop or stack the system board.

If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or a corrugated conductive material.
