ThinkPad i Series 1400 Hardware Maintenance Manual
Read This First
Before you go to the check procedures, be sure to read this section.
Important Notes
Only certified trained personnel should service the
computer.
Read the FRU service procedures before replacing
any FRUs.
Be extremely careful during write operations such as
copying, saving, or formatting. Drives in the computer that you are servicing might have been rearranged or the drive startup sequence might have been altered. If you select an incorrect drive, data or programs could be overwritten.
Ensure that you replace FRUs with the appropriate
model. When you replace the FRU, make sure that the model of the machine and FRU part number are correct by referring to the part list.
FRUs should not be replaced because of a single,
unreproducible failure. Single failure can occur for a variety of reasons that have nothing to do with a hardware defect, such as: cosmic radiation, electrostatic discharge, or software error. FRU replacement should be considered only when a recur­ring problem exists. In this case, clear the error log and run the test again. Do not replace FRUs if log errors do not reappear.
Be careful not to replace a non-defective FRU.
How to Use Error Messages
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. The cause of the first error code can result in the other false error codes being displayed.
How to Diagnose Multiple FRUs
If the adapter or device has more than one FRU, the error code could be caused by either FRU. Before replacing multiple FRUs, try removing or exchanging each FRU one by one in the designated sequence, to see if the symptoms change.
ThinkPad i Series 1400

What to Do First
The servicer must include the following in the parts exchange form or parts return form that is attached to the returned FRU:
1. Name and phone number of servicer.
2. Date of service.
3. Date when part failed.
4. Date of purchase.
5. Failure symptoms, error codes appearing on display, and beep symptoms.
6. Procedure index and page number in which 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.
Before checking problems with the computer, determine whether or not the damage applies to 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 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.

excessive force or by being dropped.
Screw Notices
The computer uses special nylon-coated screws with the following characteristics:
They maintain tight connections.They do not easily come loose, even with shock or
vibration.
They need additional force to tighten.They should be used only once.
Do the following when you service the machine:
Keep the screw kit (P/N 05K4841) in your tool bag.Always use new screws if you are instructed.Use a torque screwdriver if you have one.
Loose screws can cause a reliability problem. The IBM ThinkPad computer addresses this problem with nylon­coated screws. Tighten screws as follows:
Plastic to plastic
Turn an additional 90 degrees after the screw head touches the surface of the plastic part.
Logic card to plastic
Turn an additional 180 degrees after the screw head touches the surface of the logic card.
Torque driver
If you have a torque driver, refer to the "Torque" column with each step.

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, electronic discharge, or software errors. FRU replacement should only be consid­ered when a recurring problem exists.
When analyzing the intermittent problem, do the following:
1. Run the diagnostic test for the planar board at least 10 times.
2. If no error is detected, do not replace any FRUs.
3. If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors.
Undetermined Problems
The diagnostic tests did not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inop­erative. Follow the procedures below to isolate the failing FRU.
Verify that the power supply being used at the time of the failure is operating correctly.
1. Power off the computer.
2. Check the cables, wires, and connectors for short cir­cuits and open circuits. Visually check them for damage. If any problems are found, replace the FRU.
3. Remove or disconnect all of the following devices: Non-IBM devices
Printer, external mouse & keyboard, and other
external devices
Battery pack
Hard disk driveDiskette drive/CD-ROM/DVD-ROM drivePC Card (PCMCIA)
4. Power on the computer.
5. Determine if the problem has changed.
6. If the problem does not occur again, reconnect the removed devices one at a time until you find the failing FRU.
