Insert the flat end of a spudger underneath the press connector on the side opposite of the ribbon cable.

Use the spudger to lift the press connector up and away from the upper metal case.

Don't push the spudger all the way to the socket. Prying up the socket may damage it.

To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.
