Power Button Disconnected

The power button on my projector disconnected and fell in to the unit.

Is there a compliant way or an explanation for how I can open the unit to put it back in place?

The unit is still working by way of the remote, but I’m worried about 1) the button and associated wiring and if it may become disruptive in its current position 2) the opening that now exists in the top of the unit and how that enables dust and other elements to accrue inside where they otherwise wouldn’t.
