I don't know since when it stopped to work but as far as my concern it was working when i installed it last. as an instance my P4G Hybrid is in Quiet Office mode and by default setting for the plan while it is plugged in is Dim the disply: 5 minutes , turn off the display: 25 minutes, put the computer to sleep: 30 minutes But i can't see any reaction. If i leave my laptop on its always on...I have uninstalled and reinstalled the soft but still no luck. has anyone ever encountered this problem. please help me to resolve it.
