Installing the Processor
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 at www.dell.com/regulatory_compliance.
NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such
as a connector on the back of the computer).
NOTICE: 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.
NOTICE: To avoid damage to the processor, hold the screwdriver so that it is perpendicular to the processor when turning the cam screw.
NOTICE: To help prevent damage to the system board, remove the main battery (see Before Working Inside Your Computer) before working inside the
computer.
