Replacing the Microprocessor Module
NOTICE:
Disconnect the computer and any attached devices from electrical outlets, and remove any installed batteries.
NOTICE:
To avoid ESD, ground yourself by using a wrist grounding strap or by touching an unpainted metal surface on the computer.
NOTICE:
Read "

" before performing the following procedure.
NOTICE:
When replacing the microprocessor, to ensure proper thermal operation, always install a new thermal cooling assembly that is compatible with
the new microprocessor.
NOTICE:
Do not touch the processor die. Press and hold the microprocessor down on the substrate on which the die is mounted 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 screwdriver (perpendicular
to microprocessor)
2 pin-1 corner
3 processor die (do not
touch)
4 ZIF socket
5 ZIF-socket cam screw
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.
NOTICE:
When removing the microprocessor module, pull the module straight up. Be careful not to bend the pins on the microprocessor module.
