The CPU is held in place by a small metal door. The door is held shut by a lever with a hook. Push that lever down toward the motherboard while sliding it out from under the latch.

Once the lever is free, pull it back away from the door - this will free the door from the bar latch.

Open the door and carefully lift the CPU chip out of its socket

NOTE: The CPU is not fixed in its socket, so no force is needed when removing it.

CAUTION: Handle the CPU gently. Damage could cause it to malfunction.
