Replacing the microprocessor 124 Hardware Maintenance Manual This procedure describes how to remove and replace the microprocessor. The procedure varies depending upon the machine type. Important The heat sink and microprocessor might be very hot. Make sure these components are cool enough to safely handle before continuing this procedure. 1. Remove the side cover. See “Removing the cover” on page 117. 2. Place the computer on its right side to help make the microprocessor more accessible. 3. Disconnect the heat sink and fan assembly cable from the system board. See the system board illustration for your machine type at “System board connectors” on page 116. 4. Remove the four screws ▌1▐securing the heat sink and fan assembly to the system board.
5. Lift the heat sink and fan assembly off the failing system board. Place the heat sink on its side so that the thermal grease does not come in contact with anything. 6. To remove the microprocessor ▌2▐ from the system board, lift the small handle ▌3▐ and open the retainer ▌1▐. Important Touch only the sides of the microprocessor. Do not touch the gold contacts on the bottom. 7. Lift the microprocessor straight up and out of the socket. Chapter 9. Replacing FRUs - Tower Computers 125
