I spilled a drink all over my laptop, and as a result, my laptop keyboard was ruined. I'm using a USB keyboard now - works great. Only problem is that my laptop keyboard is malfunctioning - the keys will stick, and type a string like "vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv v" without me even pressing a key. Obviously, this is very annoying. How do I disable my laptop keyboard, so that I may use the USB keyboard alone without any problems?

Thanks in advance.
