I have a Samsung laptop model RF511-SD3 running Windows 7 Professional SP 1 (reformatted, no Samsung bloatware). I use it connected to my TV so I can browse the web in bed when I don't feel like using it on the desk. However, I can't for the life of me figure out why it goes to sleep every night. Every morning I turn the TV on and it's black. Then I go to the laptop and it's in sleep mode. I went through all the options in Energy in Control Panel and made sure it never went to sleep whatever the conditions were. And yet, every time I leave it alone for a long period of time, I go back to it asleep. What should I do? Please help!
