If i leave my computer on for and extended period of time it locks up whenever the monitor goes into power save. I'm not totally sure if the computer is completely locked. To check this is pressed the numlock key on the keyboard to see if i could toggle the light and it switched on and off. The HDD is still running and all the fans are on so i don't think it is in complete hibernate mode. so is it doing? Also i have everything about hibernating disabled and the power scheme is ALWAYS ON. The only thing that is set to go into power save is the monitor obviously. Help out:)
