Using a fingernail or spudger, flip up the retaining flap on the following three ZIF connectors.

Action button contact pad ribbon

UMD drive ribbon

Be sure you are prying up on the retaining flap, not the socket itself.

Use your fingernail or tip of a spudger to push both sides of the black retaining flap on the UMD laser ribbon socket to the right.

Use your fingers or a spudger to gently pull all three ribbon cables straight out of their sockets.
