Prerequisites
WARNING: The heat sink may be hot to touch for some time after the system has been powered off. Allow the heat sink to cool before removing it.
Follow the safety guidelines listed in the Safety instructions.
Follow the procedure listed in Before working inside your system:
Power off the system and all attached peripherals.
Disconnect the system from the electrical outlet and disconnect the peripherals.
Remove the system cover.
Remove the air shroud.
Removing the heat sink:
Using a Phillips 2 screwdriver, loosen the captive screws on the heat sink in the order mentioned below:
a. Loosen the first captive screw three turns.
b. Loosen the captive screw diagonally opposite to the screw you loosened first.
c. Repeat the procedure for the remaining two captive screws.
d. Return to the first screw to loosen it completely.
Lift the heat sink away from the system.
Removing the processor:
Release the socket lever by pushing the lever down and out from under the tab on the processor shield.
Lift the lever upward until the processor shield lifts.
CAUTION: The processor socket pins are fragile and can be permanently damaged. Be careful not to bend the pins in the processor socket when removing the processor out of the socket.
Lift the processor out of the socket.
NOTE: Ensure that the processor and the bracket are placed in the tray after you remove the heat sink.
Installing the processor:
Align the pin 1 indicator of the processor with the triangle on the socket and place the processor on the socket.
CAUTION: Positioning the processor incorrectly can permanently damage the system board or the processor. Be careful not to bend the pins in the socket.
Lower the socket lever and push it under the tab to lock it.
NOTE: If the processor has previously been used in a system, remove any remaining thermal grease from the processor by using a lint-free cloth.
Installing the heat sink
If you are using an existing heat sink, remove the thermal grease from the heat sink by using a clean lint-free cloth.
Use the thermal grease syringe included with your processor kit to apply the grease in a quadrilateral design on the top of the processor.
CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.
NOTE: The thermal grease syringe is intended for single use only. Dispose the syringe after you use it.
Align the captive screws on the heat sink with the hole on the system board.
Using the Phillips 2 screwdriver, tighten the captive screws on the heat sink in the order below:
a. In a random order, tighten the captive screws three turns.
b. Tighten the captive screw diagonally opposite to the screw you tighten first.
c. Repeat the procedure for the remaining two captive screws.
d. Return to the first screw to tighten it completely.
e. Check all the captive screws to ensure they are firmly secured.
Install the air shroud.
Follow the procedure listed in After working inside your system.
Replace the system cover.
Reconnect the peripherals and connect the system to the electrical outlet, and then power on the system.
While booting, press F2 to enter System Setup and check that the processor information matches the new system configuration.
Run the system diagnostics to verify that the new processor operates correctly.
