CAUTION: Before you begin the following procedure, follow the safety instructions that shipped with your computer.
1
processor module
NOTICE: To avoid damage to the processor, hold the screwdriver so that it is perpendicular to the processor when turning the cam screw.
1
ZIF socket
2
ZIF-socket cam screw
NOTICE: To ensure maximum cooling for the processor, do not touch the heat transfer areas on the processor heatsink assembly. The oils in your skin
can reduce the heat transfer capability of the thermal pads.
NOTICE: When removing the processor module, pull the module straight up. Be careful not to bend the pins on the processor module.
5. Lift the processor module from the ZIF socket.
Replacing the Processor Module
1. Align the pin-1 corner of the processor module with the pin-1 corner of the ZIF socket, then insert the processor module.
When the processor module is properly 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 properly.
2. Tighten the ZIF socket by turning the cam screw clockwise to secure the processor module to the system board.
3. Replace the processor heatsink assembly (see Replacing the Processor Heatsink Assembly).
4. Replace the bottom of the base assembly (see Replacing the Bottom of the Base Assembly).

Back to Contents Page
CAUTION: Before you begin the following procedure, follow the safety instructions that shipped with your computer.
NOTICE: Do not touch the processor die. Press and hold the processor down on the substrate on which the die is mounted while turning the cam screw
to prevent intermittent contact between the cam screw and processor.
NOTICE: Ensure that the cam lock is in the fully open position before seating the processor module. Seating the processor module properly in the ZIF
socket does not require force. A processor module that is not properly seated can result in an intermittent connection or permanent damage to the
microprocessor and ZIF socket.
NOTE: If a new processor is installed, you will receive a new heatsink assembly, which will include an affixed thermal pad, or you will receive a new
thermal pad along with a tech sheet to illustrate proper installation.
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.

Diagnostic Lights
Your computer has three keyboard status lights located above the keyboard. During normal operation, the keyboard status lights display the current status
(on or off) of the Num Lock, Caps Lock, and Scroll Lock features. If the computer starts without error, the lights flash, and then turn off. If the computer
malfunctions, however, you can use the status of the lights to help identify the problem.
