For a while I have had no problems with my Asus laptop running Windows 7. It is a decent computer and I need it to run almost 24/7. I restart it every few days but it does continuously run. However, recently my computer has randomly been going into sleep mode. This from the best of my knowledge, has been after I have not been using the computer for a while.
Before people suggest the more obvious solutions, I have checked all power settings for my laptop. They all say never/always on.
