Important Notes Only certified trained personnel should service the computer. Read the FRU Removal and Replacement 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 might be overwritten. Replace FRUs only for the correct model. When you replace a FRU, make sure 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 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 this is suspected, 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. ThinkPad 560Z HMM 3 Screw Tightening Information Loose screws can cause a reliability problem. The IBM ThinkPad computer addresses this problem with nylon-coated 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" instruction with each step. 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. Whatever caused 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 "Symptom-to-FRU Index" on page 21. Port Replicator Problems: If you suspect a problem with the port replicator, see "Port Replicator Checkout" on page 13. 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. 4 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 that the machine 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 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 that the system was subjected to stress beyond normal use: The following is not covered under the warranty: LCD panel cracked by applying excessive for 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). ThinkPad 560Z HMM 5 The following symptoms might indicate damage caused by nonwarranted activities: Missing parts might be a symptom of unauthorized service or modification. HDD spindles can become noisy from being subjected to excessive force or from being dropped. I9990303 errors can be caused by exposure to strong magnetic fields. How to Disable the Power-On Password: When Only the Power-on Password is Set. 1. Power off the computer. 2. Turn the computer upside down. 3. Loosen the DIMM socket lid screw 1 , and remove the DIMM socket lid 2 . 4. Short the power-on password jumper pads (R522) 3 . 1 2 3 5. Power on the computer and wait until the POST ends. The password is cleared. 6. Reinstall the DIMM socket lid, and turn the computer right side up. 7. Verify that the password prompt does not appear. 8. To reactivate the password, set the password again. 6 When Both Power-on Password and Supervisor Password are Set 1. Power off the computer. 2. Press and hold F1; then power on the computer. After a few seconds, the password prompt appears. 3. Enter your supervisor password. The Easy-setup Main Menu appears. 4. Select Password and then Power on. A rectangular box appears. 5. Enter your supervisor password and press the Space bar once. 6. Press Enter twice. 7. Select Exit. 8. Select Restart on the Easy-Setup Main Menu and wait until the POST ends. 9. Reinstall the DIMM socket lid, and turn the computer right side up. Verify that the password prompt does not appear. To reactivate the password, set the password again. Power Shutdown Switch: The Power Shutdown switch resets the system regardless of the microcode status and forces a power off. Use this push button to power off when power is not completely off or when the microcode is in a hung state. See "Bottom View" on page 73 for the location of this switch.
