No, I never bothered about them on my last machine, I was just checking through everything when I seen the Power and remembered seeing on YouTube something saying never to switch off your computer, there also used to be a Hibernate button next to the Sleep, so I was thinking about keeping the computer almost permanently on sleep when not in use.
I used to always switch it off when it wasn't in use, then I starting thinking that always starting it up was maybe part of the problem with my last computer.
