9. Close the display and turn the computer upside down on a flat work surface.



10. Slide and hold the battery-bay latch release on the bottom of the computer, and then remove the battery from the bay.



CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as

authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not

authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

CAUTION: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of

your computer's electronic components. You can do so by touching an unpainted metal surface.

CAUTION: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal

mounting bracket. Hold a component such as a microprocessor by its edges, not by its pins.

NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.

NOTE: Ensure that the computer is off and not in a power management mode. If you cannot shut down the computer using the computer operating

system, press and hold the power button for 4 seconds.

NOTICE: To avoid damaging the system board, you must remove the main battery before you service the computer.

11. Remove any installed memory modules, Mini PCI cards, and modules, including a second battery if one is installed.

12. Remove the hard drive.

Microprocessor Module

Dell™Latitude™D600ServiceManual



Removing the Microprocessor Module



1. Follow the instructions in "Preparing to Work Inside the Computer."

2. Remove the keyboard.



3. Remove the microprocessor thermal-cooling assembly.



4. 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: 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.

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.

NOTE: The ZIF-socket cam screw secures the microprocessor to the system board. Take note of the arrow on the ZIF-socket cam screw.

5. Lift out the microprocessor module.



Installing the Microprocessor Module



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



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."



NOTE: See Mini RSL for microprocessor part numbers.

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.

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.
