Windows speed and wake timers?

[P4Clock]

Is it possible to set windows to turn on/off at set times?

i have a Plex server running windows 10 and there is a good 12 to 14 hours a day that it not been used but the system is sitting idle and just using power for the sake of it

From about 1am till 4pm the system could be powered off, but the system is sitting in the loft and it would be unpractical to go up there to turn on and off manually

so if i make a batch file to tell the system to sleep in X hours i can make the system wake from sleep to run the file.
