3 Extend the release lever on the socket fully.
NOTICE:
You must position the processor correctly in the socket to avoid
permanent damage to the processor and the computer when you turn on the
computer.
4 Align the pin-1 corner of the processor and socket.
NOTICE:
To avoid damage, ensure that the processor aligns properly with the
socket, and do not use excessive force when you install the processor.
5 Set the processor lightly in the socket and ensure that the processor is
positioned correctly.
6 While lightly pressing down on the processor, rotate the release lever back
toward the system board until it snaps into place, securing the processor.

NOTICE:
Ensure that you apply new thermal grease. New thermal grease is critical
for ensuring adequate thermal bonding, which is a requirement for optimal
processor operation.
8 Apply the new thermal grease to the top of the processor.
NOTICE:
Ensure that the floppy drive and audio cables are not routed so that they
are pinched when the heat sink assembly is installed.
