  Installing the Microprocessor Module


Removing the Microprocessor Module

CAUTION: Before performing the following procedures, read the safety instructions in the Product Information Guide.
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.
  1. Follow the instructions in Before Working Inside Your Computer.

  2. Turn over the computer.

  3. Remove the microprocessor thermal-cooling assembly. See Removing 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.
  1. 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.

  1. Use a microprocessor extraction tool to remove the microprocessor module.

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 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.

NOTICE: Hold the microprocessor down while turning the cam screw to prevent intermittent contact between the cam screw and microprocessor.
  1. Tighten the ZIF socket by turning the cam screw clockwise to secure the microprocessor module to the system board.

  2. Wipe the thermal grease off of the microprocessor thermal-cooling assembly with a clean paper towel.

  3. Replace the microprocessor thermal-cooling assembly. See Installing the Microprocessor Thermal- Cooling Assembly.

  4. Update the BIOS using a flash BIOS-update program CD. See Flashing the BIOS From a CD.
