Internet button prompts the keyboard to misbehave,how do I disable it

[Rakama]

The default browser(chrome) keeps opening on it's own mutiple times. Then the keyboard starts to misbehave by writting weird characters. I initially thought that it was the keyboard causing that but it's not. I had to replace with a new one but still the same, I disconnected it from the laptop but still laptop behaves the same. The default internet button flashes mutiple times as well of which it never used to do that. It would flash when pressed,but now it flashes on it's own. I also thought it was maybe a virus or any other malicious threat of any nature,and it prompted me to format my harddrive and to install new OS but still it behaves the same. Please kindly help 🙏🏾🙏🏾🙏🏾

First off, that is not the Internet Button; instead, it is a button that when pressed, launces the Browser you have set up in Program Default in Settings. So it is a Browser button.

Second, you said you Replaced the keyboard, but based on your description, it sounds like what you did was plug in an external keyboard -- which would not fix the problem.

My guess is that you have pressed this button A LOT!  And as a result, it is now shorting on a frequent basis and acting as if you are pressing it, when you are not.  The only "fix" for this, since you can not actually disable the built-in keyboard, would be to have it replaced.
