By deafault, Windows goes to sleep if a system is inactive. What is the criteria for inactive? Or in other words, what counts as activity?

What is the criteria for inactive? Or in other words, what counts as activity?
- the absence of 'user input' (eg keyboard activity, mouse activity, touchscreen activity)
- presence of a running application where that application has set the relevant flags (eg video playback software or TV recording software)
some reference here, but I couldn't quickly find specifics of the 'user input' definition (but it will be buried in the MSDN library documentation somewhere ;)

Usually it checked whether application is using CPU, RAM ,Network and so on. For example, if you are downloading a program then it won't go to sleep mode or when your PC is using process or ram like scanning. But if a program is only remain in RAM and there aren't any activity then PC consider idle and after time which you set, it will go to sleep mode.

Thanks, Cyber_Defend_Team. I'm still confused by the "Usually" in your message. Certain applications use small amounts if CPU time when they are being actively used by the user. For instance Word doing a periodic save or Outlook and services like indexing also use CPU time, but I don't think these thinks prevent Windows from going into sleep.

Yes, it depends on the activities they perform while using CPU and RAM for example for Word example, it might take less than 1% in CPU process and also there are other conditions for not idle. For example when you are typing , you are not using a lot of CPU or RAM but because your keyboard is in progress, it is consider as not idle. Also, if you perform some heavy process your PC not consider idle. Let say if a program keep using 10% to 30% CPU and it keep changing and it shows activity it consider not idle.
So when usage of CPU and RAM is stable and low and it also depends on network activities so if your network is working and downloading it won't consider idle and also mouse and keyboard are not moving it consider idle condition and after being idle for a while, system will goes to sleep.
