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.
  • NOTE: If you are 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.
  1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet and peripherals.
  2. Lay the system on its side, on a flat and stable surface.
  3. Open the system.
    • 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.
    • NOTE: Do not remove the processor shield retention screw.
  4. Disconnect the processor fan cable from the system board.
  5. Using a screwdriver, loosen one captive screw that secures the heat sink to the system board.
  6. Wait 30 seconds for the heat sink to loosen from the processor and loosen the screw diagonally opposite the screw removed in the previous step.
  7. Repeat steps 6 and 7 for the other pair of screws.
  8. Lift the heat sink up from the processor and set it aside upside down (thermal grease side facing up).

    • 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.
