Replacing the microprocessor
Important
Before you install or remove any component, read “Important safety information” on page v. These precautions and guidelines will help you work safely.
1.Take notice of the orientation of the beveled corner on the microprocessor 2. This is important when reinstalling the microprocessor on the system board.
2.Make sure that the handle used to remove the microprocessor is fully in the up position. Otherwise the microprocessor pins might be damaged when installing the microprocessor.
3.Position the microprocessor so that the pins are aligned with the socket and with the beveled corner in the orientation as shown.
4.Lower the handle until it is fully in the down position. This locks the microprocessor in place.
5.Place the heat sink on a clean work surface.
6.Remove the cleaning pad from its package and use the cleaning pad to wipe the thermal grease from the bottom of the heat sink.
Notes:
1.Be sure that all of the thermal grease is removed.
2.The cleaning pad and thermal grease are separate FRUs and are not included with the system board or microprocessor FRUs. These must be ordered separately and shipped along with the FRUs being replaced.
7.Use the thermal grease syringe to place 16 uniformly spaced dots of 0.01ML each on the top of the microprocessor.
