1. The system unit serial number must be restored when
the system board is replaced. To restore the system
unit serial number, select the option “Set system
identification” on the maintenance diskette. The flash
ROM on the system board contains the vital product
data (VPD)—that is, the system unit serial number,
system board serial number, and other
computer-unique data.
2. Do not turn off the computer while restoring the VPD.
The system unit serial number label is attached to the
base cover.
3. Before removing and replacing the system board
assembly, make sure that the PC Cards are removed
and the eject buttons are not sticking out. If the PC
Card eject buttons are sticking out, pull them further
out slightly and fold them to the right; then push up
the system board assembly from the bottom.
