Using the special processor tool
Ä
CAUTION: While carefully holding the system board back against the rear of the chassis, screw
in the four processor screws slowly, making sure to tighten all the screws evenly. Tighten one pair
of diagonally opposite screws 1 until the screw shank settles on the system board, then tighten
the remaining pair 2. Do not fully tighten one screw, then move on to the next. Tighten all of the
screws a little at a time, making sure the processor remains level.
