FRU replacement notices FRU replacement notices This section contains notices related to removing and replacing parts. Read this section carefully before replacing any FRU. Screw notices Loose screws can cause a reliability problem. In the ThinkPad computer, this problem is addressed with special nylon-coated screws that have the following characteristics: v They maintain tight connections. v They do not easily come loose, even with shock or vibration. v They are harder to tighten.
FRU replacement notices v Make sure that you use the correct screw. If you have a torque screwdriver, tighten all screws firmly to the torque shown in the table. Never use a screw that you removed. Use a new one. Make sure that all of the screws are tightened firmly.
FRU replacement notices Retaining the UUID The Universally Unique Identifier (UUID) is a 128-bit number uniquely assigned to your computer at production and stored in the EEPROM of your system board. The algorithm that generates the number is designed to provide unique IDs until the year A.D. 3400. No two computers in the world have the same number. When you replace the system board, you must set the UUID on the new system board as follows: 1. Install the ThinkPad Hardware Maintenance Diskette Version 1.
FRU replacement notices 3. To write ECA information, select 1. Write ECA/rework number from EEPROM, and follow the instruction. 4. To write box build date, select 4. Write box build date from EEPROM, and follow the instruction on the screen. If the system board is being replaced, try to read the ECA information from the old system board and transfer the information to the new system. If the system board is inoperable, this will not be possible.
