5. Pivot lever 1 securing the heat sink until it is fully in the up position. Remove the heat sink 2 from the system board by carefully lifting it up and off the system board. Note: If you are replacing a defective system board you must reinstall the same heat sink.
Page 23
7. Using the vacuum pen 1 , remove the microprocessor from the system board socket by lifting it straight up and out of the socket. Important Do not touch the gold contacts on the bottom of the microprocessor. If you must touch the microprocessor, touch only the sides. Notes: a.
Page 24
9. Loosen the protective cover 3 that protects the gold contacts on the microprocessor 2 but do not remove it. Use the vacuum pen 1 to pick up the microprocessor then completely remove the cover. 10. Position the microprocessor so that the notches on the microprocessor are aligned with the tabs in the microprocessor socket.
Page 25
11. Using the vacuum pen 1 , lower the microprocessor straight down into the microprocessor socket. Note: Install the black protective cover that was removed from the new microprocessor onto the defective microprocessor after the installation is complete. 12. Pivot the retaining plate 3 to the closed position and pivot the locking lever 2 to secure the microprocessor 1 in place.
Page 26
13. Slide the heat sink 2 into position over the microprocessor. Lower the lever 1 to secure the heat sink. Note: If you are replacing a defective system board, use the heat sink that was removed earlier. 14. If you are replacing the system board, continue at step 12 on page 12. If you are replacing only the microprocessor, continue at the next step.

Completing the parts replacement After replacing a failed part, you need to install any other removed parts, install the computer cover, and reconnect any cables, including telephone lines and power cords. Also, depending on the part that was replaced, you might need to confirm the updated information in the Setup Utility program.
Important Start the IBM Setup Utility program to view your system information. See “Starting the IBM Setup Utility” in your Quick Reference. If the serial number and the machine type/model listed on the Main menu do not match what is printed on the label of your computer, you must update (flash) the BIOS to change the serial number and the machine type/model.
