Step 5 Install a new CPU:
a. Set the Pick-and-Place tool with CPU over the empty CPU socket on the motherboard.
Note Align the arrow on the top of the tool with the registration mark (small triangle) that is stamped 
on the metal of the CPU socket, as shown in Figure 3-17.
b. Press the top button on the tool to set the CPU into the socket. Remove the empty tool.
c. Close the hinged CPU cover plate.
d. Clip down the CPU retaining latch with the   icon, then clip down the CPU retaining latch 
with the   icon. See Figure 3-15.
Step 6 Install a heatsink:
Caution The heatsink must have a new, undamaged thermal pad on the heatsink-to-CPU surface to ensure proper 
cooling. If you are replacing a heatsink that was previously used, you must remove the old thermal pad. 
If you are installing a new heatsink, skip to step d. below.
a. Apply an alcohol-based cleaning solution to the old thermal pad and let it soak for a least 15 
seconds.
b. Wipe all of the old thermal pad off the old heatsink using a soft cloth that will not scratch the 
heatsink surface.
