1
Remove the keyboard.
NOTICE:
You must remove the display assembly before you remove the palm
rest; the display hinges pass through the back of the palm rest.
2
Remove the EMI Shield.
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 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.
5
Use a microprocessor extraction tool to remove the microprocessor
module.
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.

Align the pin-1 corner of the microprocessor module with the pin-1
corner of the ZIF socket, and insert the microprocessor module.
