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.
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. It was actually put on computers for the sake of preserving battery life, while solving energy waste issues.
When your computer is asleep, less power is consumed to maintain your work in memory, but it doesn’t drain your battery, but even so, the work is saved to the hard disk.
So what happens when Windows 10 won’t let your monitor sleep?
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 its best if it does it automatically.
If the computer monitor won’t sleep, try the other steps mentioned below.
