How do I put my laptop's monitor into dualview mode with my primary PC's monitor?

I got an old laptop. It it an ancient machine (a dell inspiron 1510), but it's 14 inch monitor is more than good enough for what I need it for. Is there any way I can extend my desktop onto it?

Not unless you have a video input on the laptop....not too common.
