A problem you might have as well: how to turn off the screen of your laptop without changing the battery settings and without using any tools? Probably using a hotkey? Did you realize, this is not part of Windows at all?

Basically, here is the batch file you have to create for it. Yes, someone wrote a batch file for this. Create a shortcut to the batch file, assign a hotkey and be happy. You also can download the batch file from TechNet. Works on my machine (with Windows 10).

powershell (Add-Type '[DllImport(\"user32.dll\")]^public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::SendMessage(-1,0x0112,0xF170,2)
