Step 8. Unlock the processor-locking mechanism using the CPU install tool (P/N 5069-5441), or equivalent

2.5 mm hex tool, shipped with your replacement processor assembly. Insert the tool into the lock

and rotate the special processor tool 180 degrees counterclockwise. Verify that the processor-locking

mechanism is rotated into the unlocked position.

WARNING The zero insertion force (ZIF) socket for the processor is locked and

unlocked by 1/2 of a full turn of the 2.5 mm hex tool. The counterclockwise

180 degree rotation (1/2 turn) unlocks the socket. A clockwise 180 degree

rotation locks the socket. Attempting to turn the locking mechanism more

that 180 degrees can severely damage the socket.
