Important Notes

Only certified trained personnel should service the computer.
Read the entire FRU removal and replacement page before replacing any FRU
Use new nylon-coated screws when you replace 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 can be written over.
Replace FRUs only for the correct model.
When you replace the FRU, make sure the model of the machine and FRU part number are correct by referring to the part list.
A FRU should not be replaced because of a single, unreproducible failure.
Single failures can occur from 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. If you suspect an unreproducible failure, clear the error log and run the test again. Do not replace any FRUs if log errors do not reappear.
Be careful not to replace a nondefective 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 false error codes being displayed. If no error code is displayed, see if the error symptom is listed in the below referenced Symptom-to-FRU Index

For ThinkPad 240 - 2609 see > Symptom-to-FRU Index
For ThinkPad 570 - 2644 see > Symptom-to-FRU Index
For ThinkPad 600, 600E - 2645 see > Symptom-to-FRU Index

Port Replicator Problems

If you suspect a problem with the port replicator, see 'Port Replicator Checkout'.

How to Diagnose Multiple FRUs

When 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.

What to Do First

The servicer must include the following in the FRU exchange form or FRU return form that is attached to the returned FRU.

Name and phone number of servicer
Date of service
Date when FRU failed
Date of purchase
Failure symptoms, error codes appearing on display, and beep symptoms
Procedure index and page number in which failing FRU was detected
Failing FRU name and FRU number
Machine type, model number, and serial number
Customer's name and address
