Rotate the outer ring of the air outlet port counterclockwise to provide slack in the ribbon cable.

As the ribbon cable becomes slack, you can put a finger under it to support it and gently pull the cable upwards from the frame.

Do not pull the ribbon cable more than an inch and a half from the top of the black plastic housing. Pulling the ribbon cable too far could damage it.

Grip the thin sides of the hard plastic tab on the end of the ribbon cable which connects to the motherboard.

Gently pull the hard plastic end of the ribbon cable upwards from the top of the motherboard, and wiggle it slightly from side to side to disconnect it.
