Also this is my first Thinkpad so I don't know how to use the fingerprint reader, camera, and even the keyboard light. Just a user's guide would be nice.
Well the first two depend on your operating system, so you might want to consult your OS's documentation. The last one is simple: Fn + the the key with the picture of a light in the top right corner of your keyboard. Given that it's a light, there's really not much more than "on" and "off".
