Need assistance disabling laptop keyboard

[Jeff.]

OK, well i have a lenovo laptop that my daughter has decided to rip litterly eversingle key off along with breaking all the clips and completly destroying it, only thing that works is the touchpad and the left and right mouse buttons, i currently use a walmart usb keyboard which is fine, but i was wondering if its possible to disable the keyboard on the laptop but still keep the touchpad and mouth buttons working, only reason why is because it is so jacked up LM keeps telling me i may have some malicious thing monitoring my hardware..which i know is caused from my 2 year old and it sometimes takes away focus from certain apps. I appreciate any assistance ,Thank you in advance...Ps loving Maya!
