FRU Service Procedures
Review the following procedures before replacing any
FRUs.
Replacing the System Board
Restoring the System Unit Serial Number
The system unit serial number is written on the label
attached to the bottom cover of the computer and is also
stored as vital product data (VPD) in the EEPROM on the
system board.
When you replace the system board, you must set the
system unit serial number on the new system board to its
original number as follows:
1. Press and hold F1 and power on the computer.
2. Hold down F1 until the Easy-Setup menu appears.
3. Click on Config.
4. Press Ctrl + N. The System Unit Serial Number
menu appears.
5. Follow the instructions on the menu.
Notes:
1. Do not power-off the computer during the restoring
process.
Updating the Universally Unique IDentifier (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 unique number is designed to
provide unique IDs until the year 3400 A.D. Consequently,
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. Press and hold F1 and power on the computer.
2. Hold down F1 until the Easy-Setup menu appears.
3. Click on Config.
4. Press Ctrl + G. The UUID menu appears.
5. Press F5 to generate a new UUID and press Enter to
overwrite it to the EEPROM.
