Holding a key disables my touchpad, and i can't find a fix at all

Alienware r4 17", bought it in March or April this year.

I've been looking it up for an hour or so, but I'm getting fixes sending me into the registry for folders that dont exist. 

I'm away from home for work, brought my laptop to do some gaming while I'm in my hotel room, but forgot my receiver for my mouse (d'oh!). It limited the games i can play, but when i hold a key for forward (w) my touchpad stops responding after about a second.  So far as I can tell, my touchpad gets overridden by the key trying to repeat, but I can't find out how to disable that. Without a fix, I'm not having a beer and gaming in my hotel, im just drinking alone staring at a screen and getting angry, and everyone knows thats not acceptable.

But all jokes aside, if someone can give me something that works, I would be extremely thankful.
