Installing the Microprocessor Module
Removing the Microprocessor Module
1. Follow the instructions in "Preparing to Work Inside the Computer."
2. Remove the center control cover.
3. Remove the keyboard.
4. Remove the display assembly.
5. Remove the palm rest.
6. Remove the microprocessor thermal-cooling assembly.
7. To loosen the ZIF socket, use a small flat-blade screwdriver and rotate the ZIF-socket cam screw counterclockwise until you cannot turn the screw any
further.
8. Lift the microprocessor module from the system board.
Installing the Microprocessor Module
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide.
NOTICE: 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.
NOTICE: Do not touch the processor die. Press and hold the microprocessor down on the substrate on which the die is mounted while turning the cam
screw to prevent intermittent contact between the cam screw and microprocessor.
NOTICE: To avoid damage to the microprocessor, hold the screwdriver so that it is perpendicular to the microprocessor when turning the cam screw.
NOTICE: To ensure maximum cooling for the microprocessor, do not touch the heat transfer areas on the microprocessor thermal-cooling assembly. The
oils in your skin reduce the heat transfer capability of the thermal pads.
NOTICE: When removing the microprocessor module, pull the module straight up. Be careful not to bend the pins on the microprocessor module.
