Lenovo laptop stuck on logo what to do?

Unfortunately I have the latest problem that when I turn on my laptop suddenly gets stuck and I don't know what to do. No matter what kind of button you press, it doesn't change anything and this one on the side is hot. Unfortunately, I know nothing about technology. In total, this has now been hanging for 20 minutes

Long press the on / off switch.

then start as usual…

if that happens again, back up your data and reinstall Windows accordingly
