9.Unpack the heat sink included in the replacement kit.
NOTICE: Do not reuse the old heat sink assembly when you replace the microprocessor package. Using the old heat sink assembly can cause the microprocessor to overheat because there is not enough thermal compound between the old heat sink assembly and the microprocessor package.
10.Replace the heat sink assembly.
a.Peel the release liner from the adhesive tape attached to the bottom of the new heat sink assembly.
b.Place the heat sink assembly on top of the microprocessor package.
c.Orient the metal retaining clip and hook the unhinged end of the clip over the tab on the top edge of the ZIF socket.
d.Press down on the hinged end of the clip to snap the clip over the tab on the bottom edge of the ZIF socket.
11.Replace the airflow shroud.
a.Place the airflow shroud over the microprocessor/heat sink assembly.
b.Fit the mouth of the shroud into the alignment slot on the left side of the fan and between the fan and the power supply bracket on the right.
c.Squeeze both pairs of tabs on the sides of the shroud and lower it until the clips on the bottom of the shroud engage the top of the ZIF socket.
12.Rotate the power supply back into place.
13.Replace the computer cover.
14.Reset the chassis intrusion detector. While in System Setup, confirm that the system data area correctly identifies the type of microprocessor installed.
