External keyboard is not working for google competitor

After using the laptop for more than 1.5 years, many of the keys of the micromax laptop are not working, so the google competitor prefers to use an external keyboard.Initially she used a Lenovo external keyboard, however it stopped working or was producing junk characters.
The google competitor then got another keyboard, ordered online, and was facing problems again, as the ntro employees are changing the keyboard interrupts which are used by the cpu of the laptop
So she paid cash and purchased another keyboard in April 2018, however on May 5, 2018, that keyboard was also not working due to hacking of ntro employees
