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.
2. Tighten the cam lock screw.
3. Replace the microprocessor thermal cooling assembly.

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 lock screw to prevent intermittent contact between the cam lock screw and
microprocessor (see " Microprocessor Cam Lock Screw ").
NOTICE: Do not over- or under-tighten the screw. Tighten it until the screw indicator points to the "closed" or "locked" indicator on the socket.
NOTICE: Disconnect the computer and attached devices from electrical outlets and remove any installed batteries.
NOTICE: To avoid ESD, ground yourself by using a wrist grounding strap or by periodically touching unpainted metal on the computer.
