Hi everyone,
It a painful, but i manage to get my keyboard back. It wasn't working in safe mode, I try the repair option, it took some times but my laptop is working again. I haven't get the chance to re-install Veyon on it because it start working just in time for class. I'll try to "clean" the laptop before trying to re-install Veyon.
Thanks again for the help.
3 hours later I can confirm that the laptop is working as a charm and I was able to install Veyon on it.
