Take Apart Logic Board - 75
jumper with a new warranty sticker, which comes with the
replacement logic board. This sticker must be in place to
protect the customer’s product warranty.
IMPORTANT: If you are replacing the logic board and the new
logic board does not come with a voltage regulator, you
must transfer the voltage regulator from the old logic board
to the new board.
Note: Before returning the logic board to Apple, remove the
processor module, processor jumper block and warranty
sticker, DRAM, SGRAM, the I/O card, and any PCI cards (if
present). Do NOT remove the voltage regulator or ROM
DIMM.
