Use this manual along with the diagnostics tests to troubleshoot problems effectively. The manual is divided into sections as follows: v The introduction section provides general information, guidelines, and safety information required to service computers. v The product-specific section includes service, reference, and product-specific parts information. This manual is intended for trained servicers who are familiar with ThinkPad products. Use this manual along with the PC-Doctor to troubleshoot problems effectively. Read This First Before you go to the checkout guide, be sure to read this section. Important Notes: v Only certified trained personnel should service the computer. v Read the entire FRU service procedures before replacing any FRUs. v Use new nylon-coated screws when you replace FRUs. v 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. v Replace FRUs only for the correct model. When you replace a FRU, make sure the model of the computer and FRU part number are correct by referring to the FRU parts list. v A FRU should not be replaced because of a single, unreproducible failure. Single failures can occur for 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 1 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 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 the display, and beep symptoms 6. Procedure index and page number in which the failing FRU was detected 7. Failing FRU name and part number 8. Computer 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 that the system was subjected to stresses beyond normal use: The following is not covered under warranty: v LCD panel cracked by applying excessive force or from being dropped v Scratched (cosmetic) parts v Cracked or broken plastic parts, broken latches, broken pins, or broken connectors caused by excessive force v Damage caused by liquid spilled into the system v Damage caused by the improper insertion of a PC Card or the installation of an incompatible card v Damaged or bent PC Card eject button v Fuses blown by attachment of a non-supported device v Forgotten computer password (making the computer unusable) 2 ThinkPad s30, s31 v Sticky keys caused by spilling liquid onto the keyboard The following symptoms might indicate damage caused by non-warranted activities: v Missing parts might be a symptom of unauthorized service or modification. v Hard disk drive spindles can become noisy from being subjected to excessive force or from being dropped. How to Disable the Password There are three passwords used at a typical customer site: the Supervisor Password, the hard disk drive password, and the Power On password. v Power On password: 1. Power off the computer. 2. Remove the battery pack and AC Adapter. 3. Remove the keyboard, see "1020 Keyboard ASM" on page 31. 4. Short the jumper JP1. See the following figure: JP1 5. Replace the keyboard. 6. Power on the computer and wait until POST ends. 7. Verify that the password prompt does not appear. v Supervisor and hard disk drive passwords: The Supervisor Password and hard disk drive password are security features that are used to protect the system and the hard disk drive data from unauthorized access. No overriding capability is provided, so they cannot be replaced if they are forgotten. If the customer forgets the Supervisor Password, the system board must be replaced. If the customer forgets the hard disk drive password, the hard disk drive must be replaced.
