CAUTION:
1) When handling NVRAMs, keep them away from any objects that can
cause static electricity. The data in NVRAMs may be corrupted by
static electricity.
2) Make sure the NVRAM is correctly installed on the board. A half-disk
[C] is engraved on one side of the NVRAM, while a guide mark [D] is
on one side of the NVRAM slot. Install the NVRAM so that the half-
disk and the guide mark are on the same side.
NOTE:
1) Before replacing the NVRAM, make sure the SMC reports (“SP Mode
Data” and “Logging Data”) has been printed out.
2) After replacing the BCU or controller, remove the NVRAM on the old
board and install it on the new board. If the NVRAM on the old board is
defective, replace the NVRAM (
