Black screen "HP Pavilion x2 detachable"

[Abialbert2011]

Hi. I just bought a HP Pavilion x2 Detachable and already have problems with it. I turned on this morning,it turned on ok. I done all the set up required,got a couple of apps,then left it. 1 hour later when I wanted to watch a film,i couldn't turn it on. It would not turn on. The mouse cursor is there,and if I press and hold for a few seconds the power button,a message saying "Slide to shut down your PC" appears and no matter what I do it won't turn on. I have tried all the "F" buttons,"F11" "F8" "F4 ....all of them basically,but nothing. It's really frustrating,this is my sons gift from Santa,and he can't even enjoy it. 😞 please help me.. Should I take it back or what's the best thing to do??
Thanks

Thank you again ,random 14 years old. It worked. But what Was The reason for this? Why did it do that to begin with?

I'm not to sure but that's how you would usually change or log out of a account on other computers so perhaps it locks the device after a set amount of time I'm not sure though. Regards
