Symptom-to-FRU index
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 52.

Note For a device not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device.

Symptom-to-FRU index

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). 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 30.) 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 port replicator c. Printer, mouse, and other external devices d. Battery pack e. Hard disk drive f. External diskette drive or optical drive g. DIMM h. Optical disk or diskette in the internal drive i. 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 nondefective FRU): a. System board b. LCD assembly

FRU replacement notices

FRU replacement notices
This section contains notices related to removing and replacing parts. Read this section carefully before replacing any FRU.

Screw notices
Loose screws can cause a reliability problem. In the ThinkPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics: v They maintain tight connections. v They do not easily come loose, even with shock or vibration. v They are harder to tighten. v Each one should be used only once. Do the following when you service this machine: v Keep the screw kit (for the P/N, see "Miscellaneous parts" on page 179) in your tool bag. v Always use new screws. v Use a torque screwdriver if you have one. Tighten screws as follows: v Plastic to plastic Turn an additional 90 degrees after the screw head touches the surface of the plastic part:
90 degrees more

(Cross-section)

v Logic card to plastic Turn an additional 180 degrees after the screw head touches the surface of the logic card:
180 degrees more

(Cross-section)

v Torque driver If you have a torque driver, refer to the "Torque" column for each step. v Make sure that you use the correct screw. If you have a torque screwdriver, tighten all screws firmly to the torque shown in the table. Never use a screw that you removed. Use a new one. Make sure that all of the screws are tightened firmly. v Ensure torque screwdrivers are calibrated correctly following country specifications.

Retaining serial numbers

FRU replacement notices
v "Retaining the UUID" v "Reading or writing the ECA information"

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. Before replacing the system board, save the original serial number by doing the following: 1. Install the ThinkPad Hardware Maintenance Diskette Version 1.73 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: v 20: Serial number Write down that 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 ThinkPad Hardware Maintenance Diskette Version 1.73 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.

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, you must set the UUID on the new system board as follows: 1. Install the ThinkPad Hardware Maintenance Diskette Version 1.73 or later, and restart the computer. 2. From the main menu, select 4. Assign UUID. 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) are 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.

54

ThinkPad® R61, R61e, and R61i (15.4-inch widescreen)

FRU replacement notices
To check what ECAs have been previously applied to the machine, use the ECA Information Read/Write function on the ThinkPad Hardware Maintenance Diskette Version 1.73 or later. 1. Insert the ThinkPad Hardware Maintenance Diskette Version 1.73 or later, and restart the computer. 2. From the main menu, select 6. Set ECA Information. 3. To read ECA information, select 2. Read ECA/rework number from EEPROM and follow 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 ThinkPad Hardware Maintenance Diskette Version 1.73 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 ThinkPad Hardware Maintenance Diskette Version 1.73 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.

Removing and replacing a FRU

Removing and replacing a FRU
This section 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 "FRU replacement notices" on page 53. 3. Begin by removing any FRUs that have to be removed before the failing FRU. Any such FRUs are listed at the top of the page. Remove them in the order in which they are listed. 4. Follow the correct sequence in the steps for removing the 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 the 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 "Locations" on page 102. 8. When replacing a FRU, use the correct screw 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).

1160 System board, PC Card/ExpressCard slots assembly
Important notices for handling the system board When handling the system board, bear the following in mind. v At every point in the process, be sure not to drop or stack the system board. v The system board has an accelerometer, which can be broken by applying several thousands of G-forces. 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. v Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or composite. v If a system board is dropped, you must test it, using PC-Doctor for DOS, to make sure that the HDD Active Protection still functions (see below). Note: If the test shows that HDD Active Protection is not functioning, be sure to document the drop in any reject report, and replace the system board. v Avoid rough handling of any kind. v If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or conductive corrugated material. After replacing the system board, run PC-Doctor for DOS to make sure that HDD Active Protection still functions. The procedure is as follows: 1. Place the computer on a horizontal surface. 2. Run Diagnostics --> ThinkPad Devices --> HDD Active Protection Test. Attention: Do not apply physical shock to the computer while the test is running.
