Click on start and type in power options and press enter.
Go into change plan settings for your selected plan.
There will be a value in turn off screen after X and go to sleep after X
Change them into the values you want then...
Click on advanced power settings and select display, then under turn off display you will notice it has a high number as default, change this to match your previous selection.
Then go up to sleep and select the + and select sleep after...then change this to the value you hit earlier.
Press Apply then ok.
