3Remove 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.
4Remove the microprocessor module.
NOTICE: T o avoid damage to the microprocessor, hold the screwdriver so that
it is perpendicular to the microprocessor when removing the cam screw (see
“Microprocessor Modules”).
aUse a small flat-head screwdriver and rotate the ZIF socket cam
screw counter-clockwise 180 degrees to loosen the ZIF socket.
The ZIF socket cam screw secures the microprocessor assembly to
the system board assembly. Take note of the arrow on the ZIF
socket cam screw (see "Microprocessor M o dules").
NOTE: Your system has a type I or type II ZIF socket.
bUse a microprocessor extraction tool to remove the microprocessor
module.
Replacing the Microprocessor Module NOTICE: 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 micr op rocessor and
ZIF socket.
1Align the pin-1 corner of the microprocessor module with the pin-1
corner of the microprocessor socket on the system board and insert the
microprocessor module.
NOTICE: You must position the microprocessor module correctly in the ZIF
socket to avoid permanent damage to the module and the socket.
When the microprocessor module is correctly seated, all four corners
are aligned to 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 (see
“Microprocessor Modules”).
2Tighten the ZIF socket by turning the cam screw clockwise to secure
the microprocessor module to the system board assembly.
