Retaining serial numbers
This section includes the following descriptions:
“Restoring the serial number of the system unit”
“Retaining the UUID”
Restoring the serial number of the system
unit:
When the computer was manufactured, the
EEPROM on the system board was loaded with the serial
numbers of the system and all major components. The
numbers need to remain the same throughout the life of
the computer.
When you replace the system board, you must restore the
system unit serial number to its original value.
Before replacing the system board, save the original serial
number by doing the following:
1. Install the ThinkPad Hardware Maintenance Diskette
Version 1.60 and restart the computer.
2. From the main menu, select 1. Set System
Identification.
3. Select 2. Read S/N data from EEPROM.
The serial number for each device is displayed. Write
down the serial number of the system unit, designated as
follows:
20: System unit serial number
After you have replaced the system board, restore the
serial number by doing the following:
1. Install the ThinkPad Hardware Maintenance Diskette
Version 1.60 and restart the computer.
2. From the main menu, select 1. Set System
Identification.
3. Select 1. Add S/N data from EEPROM.
Follow the instructions on the screen.
Note: The serial number of the system unit is written on
the label attached on the bottom of the computer.
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
unique 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:
