The Sleep after setting in Power Options allows users to specify how long in minutes the computer is inactive (idle) before automatically going to sleep.
Sleep uses very little power, your PC starts up faster, and you’re instantly back to where you left off. You don’t have to worry that you’ll lose your work because of your battery draining because Windows automatically saves all your work and turns off the PC if the battery is too low. Use sleep when you’re going to be away from your PC for just a little while – like when you’re taking a coffee break.
This tutorial will show you how to specify how long your computer is inactive before automatically going to sleep in Windows 10.
