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 entire FRU service procedures before replacing any FRUs. 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 could be overwritten. Replace FRUs only for the correct model. When you replace a FRU, make sure that the model of the machine and 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 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. 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.
