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.

If the release lever on the processor socket is not positioned all the way up, move it to that position.

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.

When the processor is fully seated in the socket, rotate the socket release lever back down until it snaps into place, securing the processor.

12Install 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 6.

bApply thermal grease evenly to the top of the processor.

cAlign the holes on both sides of the heat sink with the heat-sink posts on the system chassis. See Figure 6-14.
