When information affects only a specific model, the model number is shown in parenthesis in the heading or is explained in the text. Before you go to the checkout guide, be sure to read this section. 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. FRUs should not be replaced because of a single, un-reproducible 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 only be considered when a recurring problem exists. If this is suspected, clear the error log and run the test again. Do not replace any FRUs if log errors do not reappear. The servicer must include the following in the parts exchange form or part 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. ThinkPad 355x, 360x, 370C, 750x, 755C, 755Cs 197
