Wacom Bamboo Tablet not reading pen?

I have a Lenovo laptop with Windows 10 (formerly 7). The tablet won't read the pen or turn "Touch" off, and there a huge delay on it. Plus, I have no idea how to work Windows 10, but then again, it wasn't working on 7. Also, all the lights are on and the pen works fine on my other computer. So how can I get it to work on this one?
