Review the following procedures before replacing any
FRUs.
Replacing the System Board: The EEPROM on
the system board contains the valid product data
(VPD)—that is, a system unit serial number an a system
board serial number. When you replace the system board,
restore the system unit serial number using the Set
system identification utility in the ThinkPad hardware
maintenance diskette. The serial number label is attached
to the computer.
Note: Do not power off the computer while restoring the
VPD.
