My dad has a Lenovo SL500 running Windows XP that he uses for work. But he can't leave the computer turned on in his bag because the computer won't go to sleep and it would die after a few hours.
I checked the control panel and there was a section about power buttons. When menu asked me to specify what I would like to happen when I close the screen, the only option was "do nothing."
Does anyone know whats wrong and how to fix it?
