Dell Inspiron 8200 - Manual (Page 9)

a. Loosen the cam screw that secures the microprocessor module. The location of the screw and the rotation direction may vary with the socket
manufacturer; look for small icons indicating open and locked positions.
b. Use the microprocessor extraction tool to remove the microprocessor module.
Replacing the Microprocessor Module
1. Align the pin-1 triangle on the microprocessor with the pin-1 triangle in the socket, insert the microprocessor into the socket, and move the
microprocessor around slightly until you feel it settle into 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.
2. Tighten the cam screw.
3. Replace the microprocessor thermal-cooling assembly.
4. Close the microprocessor retaining clip.
5. To latch the clip, insert a flat-blade scribe into the latch mechanism and pivot the top of the scribe away from the clip.

3 processor die (do not
touch)
NOTICE: If you received a flash BIOS update program floppy disk or CD with the replacement microprocessor, you must update the BIOS after replacing
the microprocessor module.
NOTICE: Proper seating of the microprocessor module does not require force.
NOTICE: A microprocessor module that is not properly seated can result in an intermittent connection and subsequent failures.
NOTICE: Hold the microprocessor down while turning the cam screw to prevent intermittent contact between the cam screw and microprocessor (see
" Microprocessor Cam Screw ").
NOTICE: Do not over- or undertighten the screw. Tighten the screw until the screw indicator points to the "closed" or "locked" indicator on the socket.
