I was actually describing the only control buttons on a standard tablet. The second tablet I recovered was an Asus transformer with a detachable screen. The screen portion only has volume and power buttons. The touch screen had stopped working until I removed the screen cables and discharged them. Unfortunately it has happened repeatedly but it always works, so I have removed the cover repeatedly. It might help to know the specific model and OS you have. I have never seen a HP Stream. Are there different size screens?
