Lenovo E540 Problems

I know I should ask Lenovo these questions. I did, but their forum has practically no activity on it. I'm hoping someone here can help.

1. The fingerprint scanner won't start with the computer. It will only start after I log in. I enabled the driver and services and all their dependencies, and set them to boot with the computer, but no luck.

2. On the login screen, there's this really annoying "NumLock is on" message. Sometimes it behaves like the "CapsLock is on" message, but most of the time it glitches and leaves a black rectangle going the whole vertical length of the screen, straight down the middle. It's really annoying, and I have no idea how to turn it off. I want to turn off the whole message, because I know NumLock is on. I also want to find the option to set it to start with the computer; I can't find it in BIOS.

3. I want the middle button of the UltraNav to behave like a MiddleClick. Right now, it only scrolls like it, but with Lenovo's scroll display and no MiddleClick functions.

Kudos to whoever can help!
