Port Replicator Problems: If you suspect a problem with the port replicator, see Port Replicator Checkout on page 18. How to Diagnose Multiple FRUs: When the adapter or the device has more than one FRU, the error code could be caused by any of them. Before replacing multiple FRUs, try removing or exchanging each FRU, one by one in the designated sequence, to see if the symptoms change.
What to Do First: The service personnel must fill in
the following information in the parts exchange form or parts return form that is attached to the returned FRU: 1. 2. 3. 4. 5. 6. 7. 8. 9. Name and phone number of service personnel Date of service Date when the part failed Date of purchase Failure symptoms, error codes appearing on the display, and beep symptoms Procedure index and page number in which the failing FRU was detected Failing FRU name and the part number Machine type, model number, and serial number Customer's name and address
Before checking problems with the computer, determine whether the damage is covered under the warranty by referring to the following: Note for Warranty: 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. The following list provides some common items that are not covered under warranty and some symptoms that may indicate the system was subjected to stresses beyond normal use: The following is not covered under the warranty: LCD panel cracked by applying excessive force or by being dropped Scratched (cosmetic) parts Cracked or broken plastic parts, broken latches, broken pins, or broken connectors caused by excessive force Damage caused by liquid spilled into the system Damage caused by improperly inserting a PC Card or installing an incompatible card Damage caused by foreign material in the FDD Diskette drive damage caused by pressing the diskette drive cover or inserting diskettes with multiple labels Damaged or bent diskette eject button CD-ROM drive damage caused by shock from excessive force, or by being dropped Fuses blown by attaching a nonsupported device Forgotten computer password (making the computer unusable)

Flash Memory Update: System setup programs and
diagnostic tests are stored in the flash memory. A flash memory update is required when: A new version of the system program is installed.
A new features or options is added to the computer. To update the flash memory, do the following: 1. Obtain an appropriate diskette containing the update. 2. Insert the System Program Service diskette into drive A, and turn on the computer with ac power or a fully charged battery. 3. Select Update system programs from the menu.

Power Systems Checkout

To determine whether a power systems problem is due to the AC Adapter or the battery, do the following: 1. Remove the battery. 2. Connect the AC Adapter and check that power is supplied. 3. Disconnect the AC Adapter and install the charged battery; then check that power is supplied by the battery. If the problem is due to the AC Adapter, go to AC Adapter Checkout If the problem is due to the battery, go to Battery Checkout on page 14 If the problem is not due to the AC Adapter or the battery, go to Backup Battery Checkout (Nonrechargeable) on page 15
AC Adapter Checkout: This checkout is used only when the computer fails under ac power.
If the problem occurs only when the AC Adapter is used with a port replicator, replace the replicator. If the power-on indicator does not turn on, check the power cord of the AC Adapter for conductivity and installation. 1. Unplug the AC Adapter cable from the computer and measure the output voltage at the cable plug. See the following figure:

Pin 1 2

Voltage (V dc) +15.5 to +17.0 Ground
If the voltage persists, go to the next step.

3. 4. 5.

b. If the voltage is correct, make sure the connection between the DC/DC card and the system board is not loose. c. Replace the DC/DC card. d. If the problem is not corrected, replace the system board. e. If the problem persists, go to Undetermined Problems on page 32. Unplug the AC Adapter cable from the ac power outlet and wait 5 minutes or longer to allow the overvoltage protection circuit to be fully discharged and initialized. Plug the AC Adapter cable into the ac power outlet. Measure the output voltage of the AC Adapter. If the voltage is still not correct, replace the AC Adapter.

Management Properties window, the computer enters hibernation mode under this condition. Note: In Windows 98, the Alarms setting in the Power Management Properties window may not be synchronous with the actual low battery condition which shows a blinking then a steady orange and may cause the alarm to sound prematurely. Note: The computer cannot enter suspend mode when it is attached to a docking station. The following events cause the computer to resume operation from suspend mode: The Fn key is pressed. The LCD cover is opened. The power switch is turned on. The resume timer is set. In Windows 95, you can set the time in the resume on timer in the Power Management Properties window. In Windows 98, the Scheduled Tasks setting has priority over the resume on timer in the Power Management Properties window. Note: The computer does not accept any event immediately after it enters suspend mode. Therefore, 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. The following events cause the computer to enter hibernation mode: The Fn + F12 keys are pressed. The Hibernation button is selected in the Fuel-Gauge program. The power switch is turned off and hibernation mode is set to Hibernate by Power Switch???. The timer conditions are satisfied in suspend mode (for operating systems other than Windows 98). A critically low battery condition occurs and hibernation mode is set to Hibernate when battery becomes low. The computer exits hibernation mode and resumes operation when the Power switch is pressed. When power is turned on, the hibernation file in the boot record on the hard disk drive is read and system status is restored from the hard disk drive.
Port Replicator Power Overload
If a power shutdown occurs intermittently when PC Card devices are used with a port replicator, suspect an over-current problem. Some PC Card devices use much power, and if at some point the required power exceeds the allowed power, a power shutdown occurs. Isolate this problem to a device by removing each device simulatneously and then using the computer under the same condition as when the power shutdown occurred. This will determine which device is causing the overload.

Symptom-to-FRU Index

The symptom-to-FRU Index lists the symptoms and errors and the possible causes. The most likely cause is listed first. Note: Perform the FRU replacement or actions in the sequence shown in the FRU/Action columns. If a FRU replacement did 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 the next possible FRUs to be replaced when servicing a computer. Numeric error codes show the errors detected in POST or system operation. In the following error codes, X can be any number. If no codes are available, use narrative symptoms. If the symptom is not listed, go to Undetermined Problems on page 32. Note: For IBM devices not supported by diagnostic codes in the ThinkPad notebook computers, see the manual for that device.

The battery indicator does not turn on when the battery is installed.

Note: If you cannot find a symptom or an error in this list and the problem remains, see Undetermined Problems.

Intermittent Problems

Intermittent system hang problems can be caused by a variety of reasons 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 recurring problem exists. When analyzing the intermittent problem, do the following: 1. Run the advanced 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

You are here because the diagnostic tests did not identify which adapter or device failed, installed devices are incorrect, a short circuit is suspected, or the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate nondefective FRUs). 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 Systems Checkout on page 13): 1. Turn off the computer. 2. Visually check them for damages. If any problems are found, replace the FRU. 3. Remove or disconnect all of the following devices: a. Non-IBM devices b. Devices attached to the port replicator c. Printer, mouse, and other external devices d. Battery pack e. Hard disk drive f. CD-ROM and FDD g. DIMM h. PC Cards 4. Turn on the computer. 5. Determine if the problem is solved. 6. If the problem is solved, 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. DC/DC card c. LCD assembly d. CPU card

The error log is not saved when the system power is turned off.
Checking the Installed Devices List
If a device is installed but its icon appears in gray shade rather than in dark shade on the basic diagnostics test menu, the device is defective. Reseat the device connectors. If the symptom remains, replace the device or the system board. If needed, adjust the contrast control to clearly distinguish the shades of the icon.
If a device that is not installed appears in dark shade (for example, FDD-2 appears in dark shade when no second FDD is installed), do the following: 1. Replace the first device in the configuration, such as an FDD-1. 2. If the problem persists, replace the system board. The Parallel, and Serial icons are always displayed in dark shade, because the icons represent subsystems of the system board, not the attachment of devices. The FDD-1 icon represents the first drive in the system configuration for each type of device. The FDD-2 icon represents the second drive, attached through a port replicator.

Diagnostic Error Codes

If an error is detected, the following appears: Large X on the left side of the device icon. Device ID (three digits) Error code (two digits) FRU code (four digits) For example:
The device ID and error code indicate the detailed portion of the FRU that caused the error. If replacing a FRU does not correct the problem, see the device ID or error code from the previous failure. If they changed, the new FRU might be defective, or it may have been incorrectly installed.
Device ID: If an error is detected by the diagnostic tests, a three-digit device ID is displayed, indicating the suspected device.

FRU Removals and Replacements
This section contains information about removals and replacements. Do not damage any part. Only certified and trained personnel should service the computer. The arrows in the Removals and Replacements section show the direction of movement to remove a FRU, or to turn a screw to release the FRU. The arrows are marked in numeric order, in square callouts, to show the correct sequence of removal. When other FRUs must be removed before the failing FRU is removed, they are listed at the top of the page. To replace a FRU, reverse the removal procedure and follow any notes that pertain to replacement. See Locations for internal cable connections and arrangement information. When replacing a FRU, use the correct screw size as shown in the procedures. CAUTION: Before removing any FRU, turn off the computer, unplug all power cords from the electrical outlets, remove the battery pack, and then disconnect any interconnecting cables. CAUTION: The battery pack contains small amounts of nickel. Do not disassemble it, throw it into fire or water, or short-circuit it. Dispose of the battery pack as required by local ordinances or regulations. Attention: Before the computer is powered on after FRU replacement, make sure all screws, springs, or other small parts are in place and are not left loose inside the computer. Verify this by shaking the computer 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. Establish personal grounding by touching a ground point with one hand before touching these units. You must use an electrostatic discharge (ESD) strap (P/N 6405959) to establish personal grounding.

Important Notice

This machine uses special nylon-coated screws with the following characteristics: They maintain tight connection. They do not easily come loose, even with shock or vibration.
They need additional force to tighten.
They should not be reused. Do the following when you service this machine: Keep the screw kit (P/N 12J0808) in your tool bag. Always use new screws. Use a torque screwdriver if you have one.

FRU Service Procedures

Review the following procedures before replacing any FRUs.
Replacing the System Board
Restoring the System Unit Serial Number The system unit serial number is written on the label attached to the bottom cover of the computer and is also stored as vital product data (VPD) in the EEPROM on the system board. When you replace the system board, you must set the system unit serial number on the new system board to its original number as follows: 1. 2. 3. 4. Press and hold F1 and power on the computer.
