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. These numbers need to remain the same throughout
the life of the computer.

If you replace the system board, you must restore the serial number of the system unit to its original value.

The serial number of the system unit is written on the label attached to the bottom of the computer.

If you can not find the serial number of the system unit on the bottom of the computer, try the following
method to get the number:

Note:

Before you perform the operation, ensure that the UEFI/Legacy setting within the
