I have bought a new keyboard that I would like to use instead of the built-in keyboard, but I'm not able to disable the keyboard.
The "Disable" button is disabled in Device Manager, and the BIOS doesn't have an option to disable the keyboard (only pointer hardware). By uninstalling the device, Windows would just automatically install it again (right?).
Is my only option to physically unplug the keyboard? It's a bit clumsy to need a screwdriver in case I forget my external keyboard though...
I have a Lenovo X220 with Windows 7.
EDIT: A solution for me, but not really an answer to the question, so I'll just edit my post..
My new keyboard has small feet that fits exactly between the number and Fx row. The pressure added is not enough to push any of the buttons - problem "solved" :)
Thanks a lot to @BBlake and @Shinrai for info on the perils of unplugging the keyboard
