Huhu, have a big problem!
I have a Lenovo Y70 touch laptop that has started writing indiscriminately and arbitrarily

I already tried it via My Computer> Control Panel> Device Manager> Disable / Uninstall Keyboard, but it can't be disabled! I've also tried disabling them via the registry HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Services \ kbdclass> Start on 4, but it still works.

I know that the keyboard is the heart of a laptop, so to speak, but when it writes indiscriminately and arbitrarily <- signs it just annoys and you can't work! I would want to deactivate the laptop keyboard somehow, possibly with a program so that I can work with an external! Please urgently for help!
