Chapter 1. Safety information

This chapter presents following safety information that you need to be familiar with before you service a 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

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 tool case away from walk areas so that other people will not trip over it.

  • Do not wear loose clothing that can be trapped in the moving parts of a machine. 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 (ESD). 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, nonrounded 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
    – Fans
    – 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.

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 / non-Lenovo features or options not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.
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 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 / non-Lenovo alterations. Use good judgment as to the safety of any non-ThinkPad / non-Lenovo alterations.

  7. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

  8. Check for worn, frayed, or pinched cables.

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

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

  1. Use product-specific ESD procedures when they exceed the requirements noted here.
  2. Ensure 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 computers.

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

Chapter 2. Important service information

This chapter introduces following important service information that applies to all machine types supported by this manual:

  •  “Strategy for replacing FRUs” on page 19
    – “Strategy for replacing a solid-state drive” on page 19
    – “How to use error message” on page 20

  • “Strategy for replacing FRUs for CTO, special-bid, and standard models” on page 20
    – “Product definition” on page 20
    – “FRU identification” on page 20

Important:

  • 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: https://pcsupport.lenovo.com/supportphonelist
  • System Disassembly/Reassembly videos that show the FRU removals or replacements for the Lenovo authorized service technicians are available in the following support site: https://support.lenovo.com/us/en/solutions/ht505031

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 a solid-state drive
Always try to run a low-level format operation before replacing a solid-state drive. This will erase all data on the drive. Ensure 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.
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 section of “Symptom-to- FRU index” on page 31.
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: 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 fact sheet for the MTM indicates which country the special bid MTM is set up for. Special-bid offering is not generally announced.
Standard mode l
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
To identify FRUs for a product, do the following:

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

When prompted to enter an NVMe password, press F1 to switch between the admin NVMe password and user NVMe password.
Notes: The NVMe password is not available in the following situations:

  • A Trusted Computing Group (TCG) Opal-compliant storage drive and a TCG Opal management software program are installed in the computer, and the TCG Opal management software program is activated.
  • For Intel® models, when an drive storage drive is installed in the computer preinstalled with the Windows 10 operating system.

Supervisor password
The supervisor password protects the system information stored in UEFI BIOS. It provides the following security features:

  • If only a supervisor password is set, a password prompt is displayed when you try to enter the UEFI BIOS menu. Unauthorized users cannot change most of the system configuration options in the UEFI BIOS menu 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.
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, 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.
How to remove the power-on password
To remove the power-on password, do one of the following:
If no supervisor password has been set, do the following to remove the power- on password:

  1. Turn off the computer.

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.

LCD Self Test When you turn on the computer and the LCD goes black, run LCD Self Test to help you determine whether
the LCD functions normally.
To run LCD Self Test:

  1. Ensure that the computer is connected to ac power. Then, press the power button for about seven seconds to turn off the computer.
  2. Press Fn, left Ctrl, and the power button at the same time. If the computer displays five solid colors in sequence across the entire screen, it indicates that the LCD functions normally.

Intermittent problems
Intermittent system hang problems might happen due to a variety of causes that have nothing to do with a hardware defect, such as cosmic radiation, ESD, 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 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).
Verify that all attached devices are supported by the computer.
Verify that the power supply being used at the time of the failure is operating correctly. See “Power system checkout” on page 24.

  1. Turn off the computer.

  2. Visually check each FRU for damage. Replace any damaged FRU.

  3. Remove or disconnect all of the following devices:
    a. Non-ThinkPad devices
    b. Devices attached to the dock
    c. Printer, mouse, and other external devices
    d. Battery
    e. Solid-state drive
    f. External diskette drive or optical drive
    g. Memory module
    h. PC cards

  4. Turn on the computer.

  5. Determine whether the problem has been solved.

  6. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU.

  7. If the problem remains, replace the following FRUs one at a time (do not replace a nondetective FRU):
    a. System board
    b. LCD assembly

Chapter 5. RAID

Redundant Array of Independent Disks (RAID) is a technology that provides increased storage functions and reliability through redundancy. It also can improve data storage reliability and fault tolerance compared with single- drive storage systems. Data loss resulting from a drive failure can be prevented by reconstructing missing data from the remaining drives.
When a group of independent physical storage drives is set up to use RAID technology, they are in a RAID array. This array distributes data across multiple storage drives, but the array appears to the host computer as one single storage unit. Creating and using RAID arrays provides high performance, such as the expedited I/O performance, because several drives can be accessed simultaneously.
Storage drive requirements for RAID levels
Your computer supports the M.2 Non-Volatile Memory Express (NVMe) solid-state drive.
Note: Ensure that your computer has two identical storage drives installed (two M.2 NVMe solid-state drives with the same capacity) for supported RAID levels. If only one drive is installed, or two different types of drives are installed, the following information does not apply.
Your computer supports the following RAID levels:

  • RAID 0: striped disk array (missing data resulting from a drive failure cannot be reconstructed)
    – Consist of two identical storage drives
    – Supported strip size: 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or 128 KB
    – Better performance without fault tolerance
    – Higher risk of data loss resulting from a member drive failure compared with non-RAID configuration

  • RAID 1: mirrored disk array
    – Consist of two identical storage drives
    – Improved reading performance and 100% redundancy

Retaining serial numbers
This topic provides instructions on the following:

  • “Restoring the serial number of the system unit” on page 60
  • “Retaining the UUID” on page 61

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.
The serial number of the system unit is written on the label attached to the bottom of the computer.
If you cannot find the serial number of the system unit on the bottom of the computer, try the following method to get the number:
Note: For Intel models, before you perform the operation, ensure that the UEFI/Legacy setting within the Startup menu in the ThinkPad Setup program is set to UEFI Only.

  1. Connect a USB memory key to the computer.

  2. Go to https://www.lenovo.com/maintenanceutilities and follow the instructions on the screen to create a Maintenance Key.

  2. When the logo is displayed, press Esc. The ThinkPad Config Information Update Utility interface is displayed.
  3. Type 1 under Enter the action desired, then press Enter. The ThinkPad Serial Number Update Utility for Asset ID screen is displayed.
  4. Type 1 under Enter the action desired, then press Enter. Then follow the instructions on the screen to restore the serial number of the system unit.

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, perform the following steps to create a new UUID for the system board if the system board does not have a UUID:
Note: For Intel models, before you perform the operation, ensure that the UEFI/Legacy setting within the Startup menu in the ThinkPad Setup program is set to UEFI Only.

  1. Connect a USB memory key to the computer.

  2. Go to https://www.lenovo.com/maintenanceutilities and follow the instructions on the screen to create a Maintenance Key.
    Note: Only an authorized Lenovo service technician can access the above Web site.

  3. Restart the computer.

  4. When the logo screen is displayed, press Esc. The ThinkPad Config Information Update Utility interface is displayed.

  5. Type 2 under Enter the action desired, then press Enter. The Auto UUID generation utility interface is displayed.

  6. Type y under Change UUID. OK? [Y/N], then press Enter. 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) is 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 or Maintenance Key.

  1. Insert the latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key, and then 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. To read the box build date, select 5. Read box build date from EEPROM, and follow the instruction 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 latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key 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 latest version of LENOVO ThinkPad Hardware Maintenance Diskette or Maintenance Key, and then 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. To write the box build date, select 4. Write box build date from EEPROM, and follow the instruction on the screen.

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.

1200 System board and beeper
Important notices for handling the system board:
When handling the system board, read the following:

  • 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.

  • 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 6 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 surface.

  • Avoid bending a system board and hard pushing to prevent cracking at each BGA (Ball Grid Array) chipset.
