Replacing the Processor Module
1. Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, then insert the processor module.
When the processor module is properly seated, all four corners are aligned at the same height. If one or more corners of the module are higher than the
others, the module is not seated properly. There should be no resistance when inserting the processor module into the ZIF socket.
2. Tighten the ZIF socket by turning the cam screw clockwise about 1/3 turn (until it stops) to secure the processor module to the system board.
3. Replace the processor heat sink (see Replacing the Discrete Graphics Heat Sink).
4. Replace the fan (see Replacing the Fan).
5. Replace the bottom of the base assembly (see Removing the Bottom of the Base Assembly).
6. Follow the procedure After Working on Your Computer.

CAUTION: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best
practices information, see the Regulatory Compliance Homepage on www.dell.com at: www.dell.com/regulatory_compliance.
NOTICE: Do not touch the processor die. Press and hold the processor down on the substrate on which the die is mounted while turning the cam screw
to prevent intermittent contact between the cam screw and processor.
NOTICE: Ensure that the cam lock is in the fully open position before seating the processor module. Seating the processor module properly in the ZIF
socket does not require force. A processor module that is not properly seated can result in an intermittent connection or permanent damage to the
microprocessor and ZIF socket.
NOTE: If a new processor is installed, you will receive a new heat sink, which will include a thermal pad, or you will receive a new thermal pad along
with a tech sheet to illustrate proper installation.
NOTE: The pin-1 corner of the processor module has a triangle that aligns with the triangle on the pin-1 corner of the ZIF socket.

NOTICE: To avoid damage to the processor, hold the screwdriver so that it is perpendicular to the processor when turning the cam screw.
