WARNING: 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 at
www.dell.com/regulatory_compliance.
CAUTION: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such as the back panel) on the computer.
CAUTION: To prevent intermittent contact between the ZIF-socket cam screw and the processor when removing or replacing the processor, press to apply slight pressure to the center of the processor while turning the cam screw.
CAUTION: To avoid damage to the processor, hold the screwdriver so that it is perpendicular to the processor when turning the cam screw.
CAUTION: Only a certified service technician should perform repairs on your computer. Damage due to servicing that is not authorized by Dell™ is not covered by your warranty.
CAUTION: To help prevent damage to the system board, remove the main battery (see Before Working Inside Your Computer) before working inside the computer.
To loosen the ZIF socket, use a small, flat-blade screwdriver and rotate the
ZIF-socket cam screw counterclockwise until it comes to the cam stop.

CAUTION: To ensure maximum cooling for the processor, do not touch the heat transfer areas on the processor thermal-cooling assembly. The oils in your skin can reduce the heat transfer capability of the thermal pads.
CAUTION: When removing the processor module, pull the module straight up. Be careful not to bend the pins on the processor module.
Lift the processor module from the ZIF socket.
Replacing the Processor Module
NOTE: If a new processor is installed, you will receive a new thermal-cooling assembly, which will include an affixed thermal pad, or you will receive a new thermal pad along with documentation to illustrate proper installation.
Align the pin-1 corner of the processor module with the pin-1 corner of the
ZIF socket, then insert the processor module.
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.
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.

CAUTION: To avoid damage to the processor, hold the screwdriver so that it is perpendicular to the processor when turning the cam screw.
Tighten the ZIF socket by turning the cam screw clockwise to secure the
processor module to the system board.
