At first this appears to be just one of these maddening control-freak things, an exercise of power for the pure sadistic pleasure of it. But after Randy’s been unchained, and locked in his cell, and left alone for a few minutes to run through it in his head, he thinks otherwise. Of course normally Randy could leave the computer on the card table while the batteries charged and then carry it over to his bed and use it there until the batteries ran down. But the batteries were removed from the machine before Attorney Alejandro gave it to him, and there don’t seem to be any ThinkPad battery packs lying around his cell. So he will have to keep it plugged in all the time, and because of the way they have set up the filing cabinet and the extension cord, he is forced by certain immutable properties of three-dimensional Euclidean spacetime to use the machine in one and only one place: right there on top of that damn filing cabinet. He does not think this is an accident.
