When installing the new controller board

Remove the NVRAM from the old controller board. Then install it on the new controller board after you
replace the controller board. Replace the NVRAM if the NVRAM on the old controller board is
defective.
• Make sure you print out the SMC reports ("SP Mode Data" and "Logging Data") before you
replace the NVRAM.
• Keep NVRAMs away from any objects that can cause static electricity. Static electricity can
damage NVRAM data.
• Make sure the NVRAM is correctly installed on the controller board.
