Preparing to Work Inside the Computer

CAUTION: Before working inside your computer, read "Safety and EMC Instructions: Portable Computers"

in your System Information Guide.

not authorized by Dell is not covered by your warranty.

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

1. Make sure that the work surface is clean to prevent scratching the computer cover.

2. Save any work in progress and close all open programs.

3. Turn off the computer and all attached devices.

NOTE: Make sure the computer is turned off and not in suspend-to-disk or hibernate mode. If you cannot shut

down the computer using the computer operating system, press and hold the power button for 4 seconds.

4. Make sure the computer is undocked.

5. Disconnect the computer from the electrical outlet.

6. To avoid possible damage to the system board, wait 10 to 20 seconds and then disconnect any attached devices.

7. Disconnect all other external cables from the computer.

8. Remove any installed PC Cards or plastic blanks from the PC Card slot.

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

NOTICE: To avoid damaging the system board, you must remove the main battery and secondary battery (if present)

before you service the computer.

10. Remove the primary battery from the battery bay and the secondary battery from the module bay, if a secondary
battery is in use.

11. Remove any installed device in the module bay.

12. To dissipate any static electricity while you work, use a wrist grounding strap or periodically touch an unpainted metal
surface.

Microprocessor Module: Dell Latitude C610/C510 Service Manual

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 ZIF-socket cam screw counter-clockwise
until it comes to the cam stop.

The ZIF-socket cam screw secures the microprocessor to the system board. Take note of the arrow on the ZIF-socket
cam screw (see "Microprocessor Module Removal

").

Replacing 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.

NOTICE: Hold the microprocessor down while turning the cam screw to prevent intermittent contact between the cam

screw and microprocessor (see "Microprocessor Module Removal

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

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