Processor

Dell™ OptiPlex™ 170L User's Guide

Replacing the Processor

CAUTION: Before you begin this procedure, follow the safety instructions in the Product Information Guide.

CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your computer's electronic components. You can do so by touching an unpainted metal surface on the computer chassis.

1. Follow the procedures in "Before You Begin."
   
   
2. Disconnect the cooling fan power cable from the FAN connector on the system board (see "System Board Components").
   
   
3. Disconnect the power cable from the 12VPOWER connector on the system board.
   
   

CAUTION: The heat sink assembly can get very hot during normal operation. Be sure that the assembly has had sufficient time to cool before you touch it.

4. Remove the heat-sink/blower assembly:
   
   
   1. Press the tab on the green securing clip to remove the clip from the retention base.

2. Remove the heat-sink/blower assembly by pressing on the retention base tab while lifting one end of the heat sink.
   
   

NOTICE: Lay the heat sink down with the thermal material facing upward.

5. Remove the two screws on the blower to remove it from the heat sink.
   
   

NOTICE: Do not discard the blower. You will reuse it. If you are installing a processor upgrade kit from Dell, discard the original heat sink. If you are not installing a processor upgrade kit from Dell, reuse the original heat sink when you install your new processor.

NOTICE: Be careful not to bend any of the pins when you remove the processor from the socket. Bending the pins can permanently damage the processor.

6. Pull the release lever straight up until the processor is released, and then remove the processor from the socket.

NOTICE: Ground yourself by touching an unpainted metal surface on the back of the computer.

NOTICE: Be careful not to bend any of the pins when you unpack the new processor. Bending the pins can permanently damage the processor. If any of the pins on the processor appears to be bent, contact Dell for instructions on obtaining technical assistance.

7. Unpack the new processor.

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.

8. If the release lever on the socket is not fully extended, move it to that position.
   
   
9. Align the pin-1 corners of the processor and socket.
   
   

NOTICE: When you place the processor in the socket, ensure that all of the pins fit into the corresponding holes on the socket.

10. Set the processor lightly in the socket and ensure that all pins are headed into the correct holes. Do not use force, which could bend the pins if the processor is misaligned. When the processor is positioned correctly, press it with minimal pressure to seat it.
    
    
11. When the processor is fully seated in the socket, pivot the release lever back toward the socket until it snaps into place to secure the processor.
    
    

NOTICE: If you are not installing a processor upgrade kit from Dell, reuse the original blower/heat sink assembly when you replace the processor.

If you are installing a processor replacement kit from Dell, return the processor to Dell in the same package in which your replacement kit was sent.

12. Reinstall the two screws that attach the blower to the heat sink.
    
    
13. Install the heat-sink/blower assembly:
    
    
    1. Place the one end of the heat-sink assembly under the tab on one side of the retention base.
       
       
    2. Lower the assembly until the heat sink fits securely under the tab on the retention base.
       
       
    3. Insert the securing clip by placing the notched end of the clip opposite the tab into the slot on the retention base. Press on the securing clip tab and lower the securing clip into place. Make sure that the notched ends of the securing clip are secured in the retention base slots.
