Replacing the Processor



1. Follow the procedures in Before You Begin.



2. Unpack the new processor, being careful not to touch the underside of the processor.



3. Lift the release lever to the release position so that the processor socket is ready for the new processor.



4. Ensure that the release lever on the processor socket is fully extended.



5. Orient the front and rear alignment notches on the processor with the front and rear alignment notches on the processor socket.



6. Align the pin-1 corners of the processor and processor socket.



7. Place the processor lightly in the processor socket and ensure that the processor is positioned correctly.



8. Pivot the processor socket release lever back towards the processor socket, and snap it into place to secure the processor.



9. Clean the thermal grease from the bottom of the heat sink.



10. Apply the new thermal grease to the top of the processor.



11. Replace the processor heat sink (see Replacing the Processor Heat Sink).



12. Replace the drive bay (see Replacing the Drive Bay).



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.

CAUTION: 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.

CAUTION: Socket pins are delicate. To avoid damage, ensure that the processor is aligned properly with the processor socket, and do not use

excessive force when you install the processor. Be careful not to touch or bend the pins on the system board.

CAUTION: You must position the processor correctly in the processor socket to avoid permanent damage to the processor.

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.

CAUTION: Ensure that the processor heat sink is correctly seated and secure.
