How to shut off laptop?

Seriously. My Inspiron 14z 5423 threw a tantrum today.  Shut down as usual but the screen said Shutting Down with the circle going around. Ten minutes later, it's still spinning. Power button, alt+ctrl+del did nothing. I finally stuck a plastic flosser end into the hole to reset.  Now -- tomorrow what will happen when I turn it on?  Will it simply restart as normal?  Will there be a record of why it couldn't shut down?

Was resetting it as so correct?  I didn't want to leave it to deplete the battery.
