Removing a microprocessor and heat sink

Attention:
• 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.
• Do not touch the microprocessor contacts; handle the microprocessor by the edges only. Contaminants
on the microprocessor contacts, such as oil from your skin, can cause connection failures between
the contacts and the socket.
