My first thought is battery dead, or a poor connection at the battery. What happens to the dome light while you are trying to crank it?

I am trying to make a binary image. I want more than just the look of the image to be black/white, but I want the actual file to be a binary file. Every pixel should be either black, or white. 

I don't just want a monochrome image. I can't have varying shades of gray, every pixel needs to be black or white.

Is this possible? I looked under Image > Mode but nothing there seems to indiciate a binary style image.
