CAUTION: To ensure maximum cooling for the processor module, do not touch the heat transfer areas on the processor thermal-cooling assembly. The oils in your skin can reduce the heat transfer capability of the thermal pads. CAUTION: When removing the processor module, pull the module straight up. Be careful not to bend the pins on the processor module. 14 Lift the processor module off the ZIF socket. Replacing the Processor Module NOTE: If the new processor module is installed, you will receive a new thermal cooling assembly, which will include an affixed thermal pad, or you will receive a new thermal pad along with documentation to illustrate proper installation. 1 Follow the instructions in "Before You Begin" on page 9. 2 Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket. NOTE: The pin-1 corner of the processor module has a triangle that aligns with the triangle on the pin-1 corner of the ZIF socket. 3 Place the processor module lightly in the ZIF socket and ensure that the processor module is positioned correctly. CAUTION: To avoid damage to the processor module, hold the screw driver perpendicular to the processor module when turning the cam screw. 4 Tighten the ZIF socket by turning the cam screw clockwise to secure the processor module to the system board. 5 Replace the processor fan and heat-sink assembly (see "Replacing the Processor Fan and Heat-Sink Assembly" on page 82). 6 Follow the instructions from step 9 to step 11 in "Replacing the Top Cover" on page 72. 7 Replace the display assembly (see "Replacing the Display Assembly" on page 55). 8 Replace the keyboard (see "Replacing the Keyboard" on page 43). 9 Replace the palm-rest assembly (see "Replacing the Palm-Rest Assembly" on page 38). 10 Follow the instructions from step 5 to step 6 in "Replacing the Optical Drive" on page 33.
