Hi I've recently upgraded my R610 to Windows 7. I've extended the desktop by HDMI onto my television. I've found that when I close the screen, the laptop switches off the output to the extended desktop - killing off the image on the TV. Basically the laptop goes into sleep mode. Under XP and Vista, I'd just correct the power options to 'Do Nothing' for Lid closing. I've done this and there doesn't seem to be any effect - it still turns off. I've uninstalled all the Samsung programs, so it's not any of those doing it. Is there any way I can force the computer to keep outputting? Thanks!
