I am having some trouble with power button. Even though I set it to shutdown action on start menu properties it gets the laptop in sleep mode when pressed.
I think this could be due to Samsung Easy Settings for my Samsung Series 7 laptop as for in last update they took off shutdown action option to the power button (just sleep / fast-on-mode / ask-when-I-press-button (which is what I have set but it actually never asks but goes to Sleep directly).
ps: Samsung Easy Settings (lousy but somehow useful app) is a quicker way to access laptop settings, therefore shutdown button acion and closed/open lid action, etc
