virtual 10key

i just got me an ibm thinkpad, and a numberspad for it so i could type, and do the numbers crunching, or so i thought. The problem is when using the pad, numberslock is on, and so is the virtual 10key on the keyboard. so i still cant type, and crunch. is there anyway to disable the virtual 10key, so i can just use the pad, and type also? And if so how?
