I knew about the u torrent scheduler just recently. Thanks all. I had used couple of softwares to have it schedule to turn off the computer at specific time. Actually sometimes there are some huge data that I copy from my HDD to friend's which may take more than hours. And now with my UPS not working when power goes at 6 AM PC gets restarted.
You should try Airytec switch Off
Airytec Switch Off - Shutdown your PC automatically or remotely from any computer or mobile phone
Irrespective of torrent or copying or anything,you can schedule your pc to shutdown/restart etc.One of the coolest feature is the Remote Web Interface,by which you can switch off your PC through Web.
I have been using this for more than couple of Years & it works perfectly..
