b. Tip the top of the heat sink up (away from the system board) while sliding it
away from the lower flange of the retention module; then, remove it from
the computer. After removal, place the heat sink on its side on a clean, flat
surface.
Note: The heat sink is keyed to a 45-degree angle in one corner of the
retention module to maintain proper orientation during installation.
Attention: The microprocessor socket lever is spring-loaded when the
microprocessor is in place. Releasing the lever too quickly or allowing it to
spring upward can damage the microprocessor and surrounding components.
9. Release the microprocessor socket lever by pressing down on the end, moving
it to the right, and slowly releasing it to the open (up) position (see Figure 46).
10. Open the microprocessor socket cover by lifting up the tab on the top edge.
Attention: Use the vacuum tool provided with the replacement part to
remove the microprocessor. Dropping the microprocessor during removal can
damage the contacts. Also, contaminants on the microprocessor contacts, such
as oil from your skin, can cause connection failures between the contacts and
the socket.
11. Remove the microprocessor using the vacuum tool and the following procedure
(see Figure 47 on page 114).
