I'm just going to answer all things i know about this matter.

Okay, so you have Lenovo gaming laptop.. They usually say all high priced laptops are gaming laptops at the stores.. So i guess it's what you could call: better than a normal laptop.
You can find the specs usually below the keyboard (I
don't mean below like: Inside computer). Usually it's some sort of sticker, somewhere on computers blank area where are no buttons or touchpad. For not so tech person like you, you don't know what is says. Which is normal.
Or there can be multiple stickers... So take picture (or type every text in the sticker(s)) into reply post. Or just tell the "super correct name" of the laptop

. Which is not "Lenovo"
Umm... From what I know those drawing pad things are USB attachable, and they
should work for every PC with windows XP, Vista, 7, 8 (or mac)
Using the touchpad may require some sort of special software, but usually the software comes on CD or you get link in the shipping box of it.
But if we want to dig deeper into the world of drawing pads I'm no use anymore.
I hope there was something useful for you
