Change power and sleep settings in windows

Change power and sleep settings in windows to stop most of the actions on your computer while it is in an idle state. Any files or applications kept open are moved to the system memory (RAM) so your system uses low power. It is most preferred since waking the computer is faster than restarting it.

Windows offers various customizable sleep setting options, so your PC sleeps exactly the way you want. For example, you can set your PC to sleep after a predefined time period has elapsed. You can even make your PC fall asleep when you close your laptop’s lid.
