My touchpad on my windows 10 won't work and I don't know how to enable it when I don't have and external mouse to use as well?

I've got no mouse which I can use to help use my laptop so Im finding it hard to find a way to enable my touchpad

It's usually a keyboard shortcut, the FN key and one of the F-keys, usually shows a small square on the key to know what one. What model laptop is it exactly?
