With the pick side of a spudger (or tweezers), peel the sticky tape from the device.
Split the front and rear panels by inserting a small pointed tool (such as a pen point or a screwdriver tip SL1.5) in the 5 plastic tabs along the sides of the device.
With tweezers (or your fingernails), carefully disconnect the wires between the PC input and the motherboard.
