My Toshiba Satellite C50-B is spamming keys sometimes

[Oddishtabby]

I had recently gotten my laptop fixed when i accidentally spilt beer on the keyboard.This caused 2 of the keys to start spamming sometimes. I have gotten an external keyboard and i want to turn the internal keyboard off permanently. How would i do this?

Open the laptop and disconnect the wire to the keyboard.

There is no setting in the BIOS to disable the keyboard and no Fn key option to disable the keyboard.
