I have bought Lenovo ThinkPad w520 and the problem that I a facing is that the display is not dimming or switching off even after setting "turn off display" after 1 minute for power as well as power and in the windows "personalize" I have set the screen saver to 10 minutes where as in under "change power settings" "Change plan Settings" I have set it to "Turn off the display" after 1 minute but then they are just not making any difference, is there anyone who can help me out here??
