Novo Button

I was recently using this equipment and suddenly it turns off, when I turn it on it doesn't react at all, until I disarmed it to accommodate the keyboard connector to see if it worked and nothing, I managed to turn it on with the "novo" button and it works fine. So the solution seems simple...

I have a Lenovo laptop ideapad 110, my tried to download a game over the internet and got a virus on the computer maybe. Every time we turn the computer on we have this boot menu that no matter what we do even go into the bios its not going away . What is the to do? Can anyone help me even if...
