How do I operate the sparking control panel?

I think you need a hand with this puzzle.

Literally.

There's a severed hand along the inner wall of this hallway, just next to the
control panel.

But you need to get it out of its case first.

There's something in the adjacent room that will help you here.

You need the hammer that's on top of the bed.  The movement controls are kind
of strange, but you should be able to get to the bed eventually.  It's on the
wall opposite from the entrance from the elevator, in the middle cubicle.
