Removing the Microprocessor Module




1. Follow the instructions in "Preparing to Work Inside the Computer."
2. Remove the keyboard.
3. Remove the EMI shield.
4. For the Inspiron 5150, remove the display panel and then remove the palm rest.


6. 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.

The ZIF-socket cam screw secures the microprocessor to the system board. Take note of the arrow on the ZIF-socket cam screw.


7. Use a microprocessor extraction tool to remove the microprocessor module.

CAUTION: Before performing the following procedures, read the safety instructions in your Owner's Manual.
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.
NOTICE: Press and hold the microprocessor down by applying slight pressure to the center of the microprocessor 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: When removing the microprocessor module, pull the module straight up. Be careful not to bend the pins on the microprocessor module.

Installing the Microprocessor Module


1. Align the pin-1 corner of the microprocessor module so that it points to the triangle on the system board, and insert the microprocessor module into the
ZIF 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. Wipe the thermal grease off of the microprocessor thermal-cooling assembly with a clean paper towel.
4. Squeeze all of the contents of the thermal grease packet (provided with the kit) on to the microprocessor thermal-cooling assembly.
5. Replace the microprocessor thermal-cooling assembly.
6. For the Inspiron 5150, replace the palm rest and then replace the display panel.
7. Replace the EMI shield.
8. Replace the keyboard.
9. Update the BIOS using a flash BIOS update program CD.

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