Scheduling StartUp and ShutDown
Currently, I keep my Ubuntu 12.10 Desktop system continuously running as I have to download some data at a particular time which generally takes half an hour.
In order to save the power (electricity)
Question:: How can I wake-up my system (from suspended or switched off mode) at a particular time i.e. 2:15 AM (everyday) and and put it in a suspension mode or switched off mode at a particular time i.e. 3:15 AM (everyday) only if the keyboard or mouse activity is not detected for particular period i.e. 15 minutes.?
N.B. The system is connected with Internet with Router which has "Always On" connection.
