Macbook Pro automatic bootup

[fre3way]

I bought a new macbook pro but noticed something weird. As soon as I opened the cover, the macbook turned on by itself. I closed it via the power button and when i reopened the lid, the macbook started once again and took me to the OS setup screen. Is this normal or is there something wrong with my macbook?

Is there a way to disable this? Reason I ask because I prefer to clean my screen while power is off. I usually do this when I first get on the computer.... and have to shut down manually everytime I open the lid just to clean the screen.

Type:

sudo nvram AutoBoot=%00​

into any command prompt and enter your password.

Thank you. And what’s the syntax for the default setting?
