Introduction

This document provides procedures for removing and installing the CPU component in your computer. Unless otherwise noted, each procedure assumes that:

  • You have performed the steps in Before Working Inside Your Computer.
  • You have read the safety information in your Dell Product Information Guide.
  • When replacing a component, you have already removed the original, if installed.
Image 1/3: 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). Image 2/3: To help prevent damage to the system board, you must remove the battery from the battery bay before you begin working inside the computer . Image 3/3: To help prevent damage to the system board, you must remove the battery from the battery bay before you begin working inside the computer .
  • Before you begin any of the procedures in this section, follow the safety instructions in the Product Information Guide.

Image 1/3: 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. Image 2/3: 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. Image 3/3: 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.
  • To avoid damage to the processor, hold the screwdriver so that it is perpendicular to the processor when turning the cam screw.

  • 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.

Image 1/1: 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.
  • 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.

  • 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.

  • 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 a tech sheet to illustrate proper installation.

Image 1/3: 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. Image 2/3: Tighten the ZIF socket by turning the cam screw clockwise to secure the processor module to the system board. Image 3/3: Replace the processor thermal-cooling assembly (see [[Topic:Dell Inspiron 1525|Replacing the Processor Thermal-Cooling Assembly]]).
  • Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, then insert the processor module.
