Here’s an issue we hear about a lot. Does your Windows 8.1 screen keep going dark after you’ve only been away for a few minutes? Does your PC keep going to sleep? Here’s how to fix it. Search Power and sleep settings in the Charms bar or just start typing it from the Metro Screen and click on the result.
Now you can set how long until the screen goes dark on both battery power and while plugged in. You can also choose how long before your PC goes to sleep.
