About this task
Attention:
v
Microprocessors are to be removed only by trained technicians.
Important: Always use the microprocessor installation tool to remove a
microprocessor. Failing to use the microprocessor installation tool may damage
the microprocessor sockets on the system board. Any damage to the
microprocessor sockets may require replacing the system board.
v
Do not allow the thermal grease on the microprocessor and heat sink to come in
contact with anything. Contact with any surface can compromise the thermal
grease and the microprocessor socket.
v
Dropping the microprocessor during installation or removal can damage the
contacts.
v
Do not touch the microprocessor contacts; handle the microprocessor by the
edges only. Contaminants on the microprocessor contacts, such as oil from your
