Sleep is an important part of any electronics’ life as it gives the machine, like your computer, time to rest and save on power when you’re not using it. It was actually put on computers for the sake of preserving battery life while solving energy waste issues.
The system assumes you’re away and cuts off power to unneeded subsystems while keeping sufficient power on so you can pick up from where you left on when you resume.
So what happens when the Windows screen is not turning off?
Well, for one, the battery is drained faster and your computer consumes more energy. You could probably try to manually put it to sleep, but it’s best if it does it automatically.
What can I do if Windows 10 monitor won’t sleep?
- Update latest drivers

Note: when you disable the game controller, you may lose virtual joystick-related features in the synapse.
