10 Unpack the new processor.
If any of the pins on the processor appear bent, see "Getting Help."
11 Align the pin-1 corner of the processor with the pin-1 corner of the ZIF socket. See
Figure 6-6.
NOTE:
Identifying the pin-1 corners is critical to positioning the processor correctly.
Identify the pin-1 corner of the processor by locating the tiny gold triangle on one corner of
the processor. Place this corner in the same corner of the ZIF socket identified by a
corresponding triangle.
12 Install the processor in the socket.
NOTICE:
Positioning the processor incorrectly can permanently damage the processor and the system
when you turn it on. When placing the processor in the socket, be sure that all of the pins on the
processor enter the corresponding holes. Be careful not to bend the pins.
a If the release lever on the processor socket is not positioned all the way up, move it to that
position.
b With the pin-1 corners of the processor and socket aligned, set the processor lightly in the
socket, making sure all pins are matched with the correct holes in the socket.
Because the system uses a ZIF processor socket, do not use force, which could bend the
pins if the processor is misaligned.
When the processor is positioned correctly, it drops down into the socket with minimal
pressure.
c When the processor is fully seated in the socket, rotate the socket release lever back down
until it snaps into place, securing the processor.
13 Install the heat sink:
a Using a clean lint-free cloth, remove the existing thermal grease from the heat sink.
NOTE:
Use the heat sink that you removed in step 7.
b Apply thermal grease evenly to the top of the processor.
c Place the heat sink onto the processor. See Figure 6-6.
d Close one of the two heat sink retention levers until it locks. See Figure 6-6.
e Repeat for the other heat sink retention lever.
14 Reinstall the baffle/back fan assembly. See "Installing the Baffle/Back Fan Assembly."
15 Close the system. See "Closing the System" in "Troubleshooting Your System."
As the system boots, it detects the presence of the new processor and automatically changes
the system configuration information in the System Setup program.
