Use this manual along with the advanced diagnostic tests to troubleshoot problems.
 Important:
    This manual is intended only for trained service technicians who are familiar with ThinkPad products. Use this
    manual along with the advanced diagnostic tests to troubleshoot problems effectively.
    Before servicing a ThinkPad product, be sure to read all the information under Chapter 1 “Safety information” on
    page 1 and Chapter 2 “Important service information” on page 23.
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.
 Important:
     Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does
     not insulate you when working with live electrical currents.
     Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease
     electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.
• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical
  accident occurs, you can then operate the switch or unplug the power cord quickly.
• Do not work alone under hazardous conditions or near equipment that has hazardous voltages.
• Disconnect all power before:
  – Performing a mechanical inspection
  – Working near power supplies
  – Removing or installing main units
• Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer
  to power-off the wall box that supplies power to the machine, and to lock the wall box in the off position.
• If you need to work on a machine that has exposed electrical circuits, observe the following precautions:
  – Ensure that another person, familiar with the power-off controls, is near you.
      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 to listed above
  This practice ensures correct grounding of the units.
• If an electrical accident occurs:
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.
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 type specified in the parts list.
    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.
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.

 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:
    http://www.lenovo.com/support/phone
    System Disassembly/Reassembly videos that show the FRU removals or replacements for the Lenovo® authorized
    service technicians are available in the following support site:
    http://www.lenovoservicetraining.com/ion/
After a system board is replaced, ensure that the latest UEFI BIOS is loaded to the system board before
completing the service action.
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.
Always try to run a low-level format before replacing a hard disk drive. This will cause all customer data on
the hard disk to be lost. Be sure that the customer has a current backup of the data before doing this task.
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.
Product definition
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 hard
  disk drives, system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.
• Remember, all CTO and CMV products are loaded in PEW under the 4-digit MT and 3-digit model, where
  model = “CTO” (Example: 1829-CTO). GAVs are loaded in PEW under the 4-digit MT and 3-digit model,
  where model = a “fixed part number”, not “CTO” (Example: 1829-F1U).
• PEW can be accessed at the following Web site:
  http://www.lenovo.com/support/site.wss/document.do?lndocid=LOOK-WARNTY
  Select Warranty lookup. Input the MT and the Serial number and the list of key commodities will be
  returned in the PEW record under COMPONENT INFORMATION.
Using eSupport
For Key Commodities (Examples - hard disk drive, system board, microprocessor, LCD, and memory)
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.

The descriptions in this chapter apply to any ThinkPad model that supports the PC-Doctor® for DOS
diagnostics program. Some descriptions might not apply to your particular computer.
Before you go to the checkout guide, be sure to read the following important notes.
 Important notes:
 • Only certified trained personnel should service the computer.
 • Before replacing any FRU, read the entire page on removing and replacing FRUs.
 • When you replace FRUs, use new nylon-coated screws.
 • Be extremely careful during such write operations as copying, saving, or formatting. Drives in the computer
   that you are servicing sequence might have been altered. If you select an incorrect drive, data or programs
   might be overwritten.
 • Replace a FRU only with another FRU of the correct model. When you replace a FRU, 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 nondefective FRU.
What to do first
When you do return a FRU, you must include the following information in the parts exchange form or
parts return form that you attach to it:
 1. Name and phone number of service technician
 2. Date of service
 3. Date on which the machine failed
 4. Date of purchase
 5. Failure symptoms, error codes appearing on the display, and beep symptoms
 6. Procedure index and page number in which the failing FRU was detected
 7. Failing FRU name and part number
 8. Machine type, model number, and serial number
 9. Customer's name and address
Note: During the warranty period, the customer may be responsible for repair costs if the computer damage
was caused by misuse, accident, modification, unsuitable physical or operating environment, or improper
maintenance by the customer. Following is a list of some common items that are not covered under warranty
and some symptoms that might indicate that the system was subjected to stress beyond normal use.
Before checking problems with the computer, determine whether the damage is covered under the warranty
by referring to the following list:
Checkout guide
Use the following procedures as a guide in identifying and correcting problems with the ThinkPad Notebook.
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.
To create the PC-Doctor diagnostic CD, follow the instructions on the Web site.
For some possible configurations of the computer, PC-Doctor might not run correctly. To avoid this problem,
you need to initialize the computer setup by use of the ThinkPad Setup program before you run PC-Doctor.
Note: If a supervisor password has been set by the customer, the ThinkPad Setup program menu appears
after the password is entered. You can start ThinkPad Setup by pressing Enter instead of entering the
supervisor password; however, you cannot change the parameters that are protected by the supervisor
password.
On the ThinkPad Setup program screen, press F9, Enter, F10, and then Enter.

Passwords
As many as three passwords may be needed for any ThinkPad Notebook: the power-on password (POP),
the hard-disk password (HDP), and the supervisor password (SVP).
If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is
turned on. The computer does not start until the password is entered.
Note: If only an SVP is installed, the password prompt does not appear when the operating system is booted.
Power-on password
A power-on password (POP) protects the system from being powered on by an unauthorized person. The
password must be entered before an operating system can be booted. For how to remove the POP, see
“How to remove the power-on password” on page 39.
Hard-disk password
There are two hard-disk passwords (HDPs):
• User HDP - for the user
• Master HDP - for the system administrator, who can use it to get access to the hard disk even if the user
  has changed the user HDP
Note: There are two modes for the HDP: User only and Master + User. The Master + User mode requires
two HDPs; the system administrator enters both in the same operation. The system administrator then
provides the user HDP to the system user.
Attention: If the user HDP has been forgotten, check whether a master HDP has been set. If it has, it can be
used for access to the hard disk drive. If no master HDP is available, neither Lenovo nor Lenovo authorized
service technicians provide any services to reset either the user or the master HDP, 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 POP, see “How to remove the hard-disk password” on page 40.
Supervisor password
A supervisor password (SVP) protects the system information stored in the ThinkPad Setup program.
The user must enter the SVP in order to get access to the ThinkPad Setup program and change the
system configuration.
Attention: If the SVP 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.
(B) If an SVP has been set and is known by the service technician:
 1. Turn on the computer.
 2. When the ThinkPad logo comes up, immediately press F1 to enter the ThinkPad Setup program. When
    the POP icon is appearing on the screen, enter the POP.
 3. Select Security, using the cursor directional keys to move the menu.
 4. Select Password.
 5. Select Power-On Password.
 6. Type the current SVP in the Enter Current Password field. then leave the Enter New Password field
    blank, and press Enter twice.
 7. In the Changes have been saved window, press Enter.
 8. Press F10 to save changes and exit the ThinkPad Setup program.
To remove a user HDP that has been forgotten, when the SVP and the master HDP are known, do the
following:
 1. Turn on the computer.
 2. When the ThinkPad logo comes up, immediately press F1 to enter the ThinkPad Setup program. When
    the POP icon is appearing on the screen, enter the POP.
 3. Select Security, using the cursor directional keys to move the menu.
 4. Select Password.
 5. Select Hard-disk x password, where x is the letter of the hard disk drive. A pop-up window opens.
 6. Select Master HDP.
 7. Type the current master HDP in the Enter Current Password field. then leave the Enter New Password
    field blank, and press Enter twice.
 8. Press F10.
 9. Select Yes in the Setup Configuration window. Both user HDP and master HDP will have been removed.
Power management
To reduce power consumption, the computer has three power management modes: screen blank, sleep
(standby in Windows XP), and hibernation.
You can also put the computer into screen blank mode, press ThinkVantage button and use the ThinkVantage
Productivity Center.
Note: If the computer is a Windows 7 model, it does not support ThinkVantage Productivity Center.
To end screen blank mode and resume normal operation, press any key.
Note: You can change the action of the Fn+F4 key combination by changing the settings in Power Manager.
In certain circumstances, the computer goes into sleep (standby) mode automatically:
• If a “suspend time” has been set on the timer, and the user does not do any operation with the keyboard,
  the TrackPoint, the hard disk, the parallel connector, or the diskette drive within that time.
• If the battery indicator blinks orange, indicating that the battery power is low.
Note: Even if you do not set the low-battery alarm, the charge indicator notifies you when the battery is low,
and then the computer enters the power-saving mode automatically.
To cause the computer to return from sleep (standby) mode and resume operation, do one of the following:
• Press the Fn key.
• Open the LCD cover.
• Turn on the power switch.
Also, in either of the following events, the computer automatically returns from sleep (standby) mode and
resumes operation:
• The ring indicator (RI) is signaled by a serial device or a PC Card device.
• The time set on the resume timer elapses.
  Note: The computer does not accept any input immediately after it enters sleep (standby) mode. Wait a
  few seconds before taking any action to reenter operation mode.
Hibernation mode
In hibernation mode, the following occurs:
• The system status, RAM, VRAM, and setup data are stored on the hard disk.
• The system is powered off.
Also, the computer goes into hibernation mode automatically in either of the following conditions:
• If a “hibernation time” has been set on the timer, and if the user does not do any operation with the
  keyboard, the TrackPoint, the hard disk drive, the parallel connector, or the diskette drive within that time.
• If the timer conditions are satisfied in suspend mode.
When the power is turned on, the computer returns from hibernation mode and resumes operation. The
hibernation file in the boot record on the hard disk drive is read, and system status is restored from the
hard disk drive.
Symptom-to-FRU index
This section contains following information:
• “Numeric error codes” on page 43
• “Error messages” on page 47
• “Beep symptoms” on page 48
• “No-beep symptoms” on page 48
• “LCD-related symptoms” on page 49
• “Intermittent problems” on page 49
• “Undetermined problems” on page 49
The symptom-to-FRU index in this section lists symptoms and errors and their possible causes. The most
likely cause is listed first, in boldface type.
Note: Do the FRU replacement or other actions in the sequence shown in the column headed “FRU or
action, in sequence.” If replacing a FRU does not solve the problem, put the original part back in the
computer. Do not replace a nondefective FRU.
This index can also help you determine, during regular servicing, what FRUs are likely to need to be
replaced next.
A numeric error is displayed for each error detected in POST or system operation. In the displays, n can
be any number.
If no numeric code is displayed, check the narrative descriptions of symptoms. If the symptom is not
described there, go to “Intermittent problems” on page 49.
Note: For a device not supported by diagnostic codes in the ThinkPad Notebooks, see the manual for that device.

 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 replacement if the LCD is within specification as we cannot guarantee that any
     replacement LCD will have zero pixel defects.
     • One pixel consists of R, G, B sub-pixels.
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.
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).
Verify that the power supply being used at the time of the failure is operating correctly. (See “Power system
checkout” on page 33.)

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 the ThinkPad Notebook, this problem is addressed with
special nylon-coated screws that have the following characteristics:
• Keep the screw kit (for the P/N, see “Miscellaneous parts” on page 129) in your tool bag.
• Always use new screws.
• Use a torque screwdriver if you have one.
• Plastic to plastic
    Turn an additional 90 degrees after the screw head touches the surface of the plastic part:
If you replace the system board, you must restore the serial number of the system unit to its original value.
Before replacing the system board, save the original serial number by doing the following:
    1. Install the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later, and restart the
       computer.
    2. From the main menu, select 1. Set System Identification.
    3. Select 2. Read S/N data from EEPROM.
The serial number of each device in your computer is displayed; the serial number of the system unit is
listed as follows:
• 20: Serial number
Note: The serial number of the system unit is also written on the label attached to the bottom of the computer.
After you have replaced the system board, restore the serial number by doing the following:
    1. Install the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later and restart the
       computer.
    2. From the main menu, select 1. Set System Identification.
    3. Select 1. Add S/N data from EEPROM. Follow the instructions on the screen.
If the MTM and Product ID numbers differ from each other on the rear label, use what is shown for the

    instruction.
 4. To read 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 LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later to update the
EEPROM.
Note: Only the ECA number is stored in the EEPROM. The machine type of the ECA is assumed be the same
as the machine type of the machine that had the ECA applied to it.
 1. Insert the LENOVO ThinkPad Hardware Maintenance Diskette Version 1.76 or later, and restart the
    computer.
 2. From the main menu, select 6. Set ECA Information.
 3. To write ECA information, select 1. Write ECA/rework number from EEPROM, and follow the
    instruction.
 4. To write 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.
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 computer unless you have been trained and certified. An untrained person runs
    the risk of damaging parts.
 2. Before replacing any FRU, review Chapter 7 “FRU replacement notices” on page 55.
 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 9 “Locations”
    on page 103.
 8. When replacing a FRU, use the correct screw(s) as shown in the procedures.
DANGER
 Before removing any FRU, turn off the computer, unplug all power cords from electrical outlets,
 remove the battery pack, and then disconnect any interconnecting cables.
Attention: After replacing a FRU, do not turn on the computer until you have made sure that all screws,
springs, and other small parts are in place and none are loose inside the computer. Verify this by shaking
the computer gently and listening for rattling sounds. Metallic parts or metal flakes can cause electrical
short circuits.
Attention: The system board is sensitive to, and can be damaged by, electrostatic discharge. Before
touching it, establish personal grounding by touching a ground point with one hand or by using an
electrostatic discharge (ESD) strap (P/N 6405959).
Some models of the ThinkPad X220 Tablet and X220i Tablet you are servicing might have the SIM card that the
customer has been installed.
If the computer you are servicing has the SIM card, remove it before you start the servicing.
To remove the SIM card, you need to remove the battery pack first. (See “1020 Battery pack” on page 61.)
After you finish the servicing, make sure that you insert the card back into the slot firmly.
Some cables used in ThinkPad X220 Tablet and X220i Tablet models are connected to flip-lock ZIF connectors.
When disconnecting a cable from a flip-lock ZIF connector, do as shown in the following figure.

When installing:
• Before you attach the fan assembly to the computer, apply thermal grease, at an amount of 0.2 grams,
  on the part marked a as in the following figure. Either too much or too less application of grease can
  cause a thermal problem due to imperfect contact with a component. You need to peel the thin film
  off from the rubber b .
• Make sure that the DC-in connector, the fan connector, and the pen switch connector are attached to
  the system board firmly.
The new base cover FRU is shipped with a kit containing labels of several kinds.
Note: If the Windows Authentication label (COA) 2 is attached to a part that is replaced, return the old part
with the label attached to the customer, or provide a letter to the customer stating what the label was
originally on the system and what the label part number, serial number, and product key were.
When you replace the base cover, you need to apply the following labels:
 19                 Homologation label
 20                 Product label
The following labels need to be peeled off from the old base cover, and need to be put on the new base cover.
For some models, you need to apply two FCC labels, 17 and 21 . Check the old base cover; if it has
two FCC labels, apply both to the new base cover.

     Note: Dropping a system board from a height of as little as 6 inches so that it falls flat on a hard bench
     can subject the accelerometer to as much as 6,000 G's of shock.
• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or
  composite.
• If a system board is dropped, you must test it, using PC-Doctor for DOS, to make sure that the HDD
  Active Protection System™ still functions.
     Note: If the test shows that the HDD Active Protection System is not functioning, be sure to document the
     drop in a reject report, and replace the system board.
• Avoid rough handling of any kind.
• At every point in the process, be sure not to drop or stack the system board.
• If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or a
  corrugated conductive surface.
Attention: Do not apply physical shock to the computer while the test is running.

    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.
    ThinkPad computers contain 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 power adapter, power cord, battery, and hard disk drive. Other Self-service CRUs
       depending on product design may include the memory module, wireless card, keyboard, and palm rest with
       finger print reader and touchpad.
    – Optional-service CRUs: These CRUs are isolated parts within the computer 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.
