Removing and Replacing Parts: Dell Inspiron 3700 System Reference
microprocessor module (see Figure 12).
4. Loosen the three captive screws securing the microprocessor shield to the microprocessor module.
5. Remove the microprocessor shield.
6. Rotate the arm of the thermal cooling assembly up and away from the microprocessor module.
NOTICE: When removing the microprocessor module, pull the module straight up. Do not move the tool from
side to side to extract the processor board.
7. Use a microprocessor extractor tool to remove the microprocessor module.
The tool fits on the left side of the module aligned with white marks on the front and back edge of the
processor board (see
Figure 12).
Replacing the Microprocessor Module
NOTICE: Proper seating of the microprocessor module requires a considerable amount of force
(approximately 35 pounds [16 kilograms]) applied above the module connector. A microprocessor module
that is not properly seated can result in an intermittent connection and subsequent failures.
When you reinstall the microprocessor module in the system board, make sure that you align the microprocessor
connector on the left side of the board and press down firmly on the metal plate that is directly over the connector.
When the microprocessor module is seated, all four corners must be at the same height. If one or more corners of
the module are higher than the others, the module is not seated correctly.
Pay attention to the corner without the mounting screw. If necessary, apply pressure directly over this corner to
ensure that the module is fully seated.
Rotate the arm of the thermal cooling assembly into place and replace the microprocessor shield. Replace the two 3-
mm screws that secure the thermal cooling assembly arm and shield to the microprocessor module. Tighten the
three captive screws on the corners of the shield to secure the microprocessor module and shield.
