for you have used the machine for more than 1 year then your touch pad need to be replaced however if it has happened abruptly then reinstall the touch pad drivers

SOURCE: New Lenovo Y430 keyboard and touchpad does not work

I bought two y430s. I've had both y430's go bad, one at 8 months, one at 16 months. Both were motherboards. 1st on warrantied, second was not. $600 pieces of garbage.

It most likely has something conductive around the edges. Clean the pad with a cloth or paper towel that has 99% isopropyl alcohol on it. Use something like a toothpick to push the cloth or paper right into the edges. Once it is clean, and completely dry, try again. If it still doesn't work you may need to check the connection inside the laptop.

It sounds like your function key is either stuck or broken. Try prying the key off (carefully) with a knife or something to check if you can see the damage. You can also try cleaning it (search google for keyboard cleaning procedures). If it's broken, you may need to purchase a new one. They can be found easily on e-bay.
