CAUTION: When removing or replacing the processor, do not touch any of the pins inside the processor socket or allow any objects to fall on the pins in the processor socket.
Gently lift the processor to remove it from the socket.
Leave the release lever extended in the release position so that the socket is
ready for the new processor.
Replacing the Processor
CAUTION: Ground yourself by touching an unpainted metal surface or the computer stand.
CAUTION: When replacing the processor, do not touch any of the pins inside the socket or allow any objects to fall on the pins in the socket.

processor is positioned correctly.
Pivot the processor socket release lever back towards the processor socket,
and snap it into place to secure the processor.
Clean the thermal grease from the bottom of the heat sink.
CAUTION: 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.
Apply the new thermal grease to the top of the processor.
CAUTION: Ensure that the processor heat sink is correctly seated and secure.
CAUTION: Before turning on the computer, replace all screws and ensure that no stray screws remain inside the computer. Failure to do so may result in damage to the computer.
