Removing the processor

  • CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
  1. Before upgrading your system, download the latest system BIOS version from dell.com/support and follow the instructions included in the compressed download file to install the update on your system.
    • NOTE: You can update the system BIOS using the Lifecycle Controller.
  2. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet. When disconnected from AC power, press and hold the power button for three seconds to fully drain the system of stored power prior to removing the cover.
  3. Open the system.
  4. Remove the cooling shroud.
    • WARNING: The heat sink and processor are hot to the touch for some time after the system has been powered down. Allow the heat sink and processor to cool before handling them.
    • CAUTION: Never remove the heat sink from a processor unless you intend to remove the processor. The heat sink is necessary to maintain proper thermal conditions.
  5. Using the #2 Philips screwdriver, loosen one heat-sink retention screw that secures the heat sink to the system board.
  6. Wait 30 seconds for the heat sink to loosen from the processor and remove the screw diagonally opposite the first screw.
  7. Repeat steps 5 and 6 for the other pair of screws.
  8. Lift the heat sink away from the processor and set the heat sink aside.

    • CAUTION: The processor is held in its socket under strong pressure. Be aware that the release lever can spring up suddenly if not firmly grasped.
  9. Position your thumb firmly over the processor socket-release lever and release the lever from the locked position by pushing down and out from under the tab. Rotate the lever upward.
  10. Rotate the processor shield upward and out of the way.
    • CAUTION: The socket pins are fragile and can be permanently damaged. Be careful not to bend the pins in the socket when removing the processor out of the socket.
  11. Lift the processor out of the socket and leave the release lever up so that the socket is ready for the new processor.
