How to disable builtin keyboard in vaio laptop

[andipy]

my laptop's builtin keyboard has got a problem. the key "k" is pressd all the time. I baught a new USB keyboard. But I need to disale the original keyboard. Otherwise I am not able to type properly.
When I went to device driver to disable it the disable button is disabled. is there any other way to get it disabled.

Hi, just disconnect the ribbon cable for the keyboard from the motherboard.
