whenever i put my inspiron 580 to sleep it wont reboot when i press the return button
Is this a desktop? You should disable any/all hibernation options and set all power options to "never" as far as turning off drives and monitors. Those options are meant for laptops to extend battery charge duration. When you want to turn your PC off, TURN IT OFF.
