Replacing the Processor Heat Sink

NOTE: The original thermal pad can be reused if the original processor and processor heat sink are reinstalled together. If either the processor or the processor heat sink is replaced, use the thermal pad provided in the kit to ensure that thermal conductivity is achieved.

NOTE: This procedure assumes that you have already removed the processor heat sink and are ready to replace it.

1. Peel the backing off the thermal pad and adhere the pad to the portion of the processor heat sink that covers the processor.
   
   
2. Slide the processor heat sink under the bracket and align the five captive screws with the screw holes on the system board.
   
   
3. Tighten the five captive screws.
   
   
4. Connect the fan connector to the system board connector.
   
   
5. Replace the module cover (see Module Cover).
   
   
6. Slide the battery into the battery bay, until it clicks into place.
