4.4.14.2 Installing a CPU and Heatsink
1. Unpack the new CPU.
Caution – Observe the appropriate ESD precautions.
2. Ensure that the socket release lever is in the fully open, perpendicular position.
3. Align the small triangle, on the corner of the CPU, with the triangle on the corner
of the socket.

4. Insert the CPU into the socket.
Note – If correctly aligned, the CPU should easily insert into the socket. If more
than minimal resistance is felt, stop and recheck the alignment. Forcing a misaligned
CPU into the socket will permanently damage the device.
5. When the CPU is fully seated in the socket, rotate the socket release lever until it
snaps into place, securing the CPU in the socket.
6. Use the syringe to apply approximately 0.1 ML/CC of thermal grease in a circular
pattern to the top of the CPU.
7. Gently distribute the thermal grease and remove any excess so that only an
extremely thin, uniform layer remains. If any voids or crevices appear that could
lead to air pockets, reapply the grease until you achieve a thin but compact
consistency.
8. Use an alcohol pad to remove all thermal grease from the bottom of the heatsink.
9. Inspect the heatsink for dust and lint. Clean if necessary.
