I'm not sure if this is the right place to post this, but I am having a very frustrating problem with my Lenovo y500 Ideapad laptop. Despite having set the computer to not log off, it still logs off after about a minute of inactivity. This is extremely frustrating. If I stop to write something in my notebook, my computer screen is black when I pick my head up, and I need to log back in. I have turned off every setting I can find for sleep/hibernation/dim screen. Every option is set to never, yet my laptop ignores this and logs off anyway. I would greatly appreciate some help. At this point I'm getting concerned about the health of the computer, getting put to sleep and woken up over and over and over.
