Microprocessor Module

Dell™ Latitude™ D600 Service Manual

Removing the Microprocessor Module

CAUTION: Before performing the following procedures, read the safety

instructions in your System 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.

1. Follow the instructions in "

Preparing to Work Inside the Computer."

2. Remove the

keyboard.

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.

3. Remove the

microprocessor thermal-cooling assembly.

NOTICE: When removing the microprocessor module, pull the module straight

up. Be careful not to bend the pins on the microprocessor module.

4. To loosen the ZIF socket, use a small, flat-blade screwdriver and rotate the ZIF­socket cam screw counterclockwise until it comes to the cam stop.

Microprocessor Module: Dell Latitude D600 Service Manual

Installing the Microprocessor Module

NOTICE: Ensure that the cam lock is in the fully open position before seating

the microprocessor module. Seating the microprocessor module properly in the
ZIF socket does not require force.

NOTICE: A microprocessor module that is not properly seated can result in an

intermittent connection or permanent damage to the microprocessor and ZIF
socket.

1. Align the pin-1 corner of the microprocessor module with the pin-1 corner of the
ZIF socket, and insert the microprocessor module.

NOTE: The pin-1 corner of the microprocessor module has a triangle that aligns

with the triangle on the pin-1 corner of the ZIF socket.

NOTICE: You must position the microprocessor module correctly in the ZIF

socket to avoid permanent damage to the module and the socket.

When the microprocessor module is correctly 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 correctly.

2. Tighten the ZIF socket by turning the cam screw clockwise to secure the
microprocessor module to the system board.

3. Replace the other computer parts you removed earlier in this procedure.

4. Update the BIOS using a flash BIOS update program floppy disk or CD. For
instructions on how to flash the BIOS, see "

Flashing the BIOS."
