For your Surface, go to your desktop. Open up the file explorer and click on desktop, then control panel. In control panel, switch the view to small icons and go to power options. Tap on advanced power options and you'll see the option to turn it off after so many minutes. Change it from the default 2 minutes to whatever you'd like for it to remain on. You can do this for both battery and plugged in.

That's the beauty of the Surface!
