Touchpad doesn't work!?

Hello.

I've got a VAIO VGN FE11M.
My touchpad doesn't work since yesterday.
It's really weird because I checked it in my device manager and it says that everything is okay.
Now I've reinstalled my whole computer because I thought that it doesn't work because of the drivers.
It still doesn't work.

Can anyone help me?

Weird but my problem got fixed...
I didn't know that I could deactive it anyway... D:

I just went into my BIOS and resetted all settings to their default.
