5-22 Removal and Replacement Procedures
CAUTION: When replacing the processor, be sure the clipped corner of the processor (location of Pin 1) is
aligned with the triangular area of the ZIF socket (marked * on the system board). Failure to do so could
result in burning out both the processor and the system board.
✎
The handle on the ZIF socket in the picture may not look identical to the one on the computer.
All handle types perform the same function.
To install the processor, complete the following steps:
1. Lower the processor into the ZIF socket. Ensure that pin 1 on the processor aligns with pin 1 on
the ZIF socket.
2. Push the ZIF handle on the ZIF socket back into place to secure the processor.
3. If the processor has a raised center, install thermal pad number 243226-001 3 on top of the
processor before installing the heatsink.
If the processor has a flat center, install thermal pad number 184616-002 3 on top of the
processor before installing the heatsink.
CAUTION: Using the wrong thermal pad may cause the processor to overheat or short, resulting in failure.
4. Install the heatsink and the heatsink retaining clip.
5. Return the drive cage to the normal position.
CAUTION: Check the position of all cables and wires before raising or lowering the drive cage to prevent
damage.
6. Replace the system unit cover.
