Replacing the microprocessor This section provides instructions on how to replace the microprocessor. 1. Open the computer cover. See "Opening the cover" on page 84. 2. Locate the microprocessor. See "System board locations" on page 83. 3. Remove the four screws securing the heat sink to the retention module on the system board and lift the heat sink off the system board. 4. Disengage the microprocessor from the system board socket by pivoting the small handle upward until it is in the vertical position. 5. Lift the microprocessor straight up and out of the socket. Notes: a. Your microprocessor and socket might look different than the one illustrated. b. Note the orientation of the microprocessor in the socket. Look for the small triangle on one corner of the microprocessor. This is important when reinstalling the microprocessor on the system board. c. Do not drop anything onto the microprocessor socket while it is exposed. The socket pins must be kept as clean as possible. 6. When installing the microprocessor make sure that the small handle is in the vertical position. 86 Hardware Maintenance Manual

screws
securing
the
heat
sink
to
the
retention
module
on
the
system
board
and
lift

the
small
handle
upward
until
it
is
in
the
vertical
position.
5.
Lift
the
microprocessor
straight
up

Notes:
a.
Your
microprocessor
and
socket
might

one
illustrated.
b.
Note
the
orientation
of
the
microprocessor
in
the
socket.
Look
for
the
small
triangle
on
one
corner
of
the
microprocessor.
This
is
important
when
reinstalling
the
microprocessor
on
the
system
board.
c.
Do
not
drop
anything
onto
the
microprocessor
socket
while
it

The
socket
pins
must
be
kept
as
