(J) NOTICE: If you received a flash BIOS update program diskette or CD with the replacement microprocessor, you must update the BIOS after replacing the microprocessor module. For instructions on updating or reflashing the BIOS, see the Dell Portable Computer BIOS Update Guide.
(J) NOTICE: Proper seating of the microprocessor module does not require force.
Q NOTICE: A microprocessor module that is not properly seated can result in an intermittent connection and subsequent failures.
1. Align the pin-1 triangle on the microprocessor toward the pin-1 triangle in the socket, insert the microprocessor into the socket, and move it 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.
Q NOTICE: Hold the microprocessor down while turning the cam lock screw to prevent intermittent contact between the cam lock screw and microprocessor (see "Microprocessor Cam Lock Screw").
Q NOTICE: Do not over- or undertighten the screw. Tighten it until the screw indicator points to the "closed" or "locked" indicator on the socket.
3. Replace the microprocessor thermal cooling assembly.
