Unlock CPU by turning the locking screw 180 degrees counterclockwise using Flathead screwdriver. You will hear a slight click when CPU is fully unlocked.
Carefully lift CPU upwards by holding it from both sides.
It is important to lift CPU straight upward in order to not bend any pins on it.
For reassembly, make sure to put CPU back by matching a small yellow triangle in the corner of CPU to the small triangle imprinted on the CPU socket.
