I am running Big Sur 11.2.3 and out of the blue today my computer won't wake up with the keyboard or the mouse. I have to click the power button on the back of the monitor to wake it up. Anyone else having this issue.
iMac 27″, macOS 11.2
What you are experiencing is easily fixed by going into settings, then energey saver and ticking the box that says 'Prevent computer from sleeping automatically when the display is turned off'. I noticed this new setting when I installed Big Sur. It basically means that unticked, when your display goes to sleep, so does your computer, causing you to have to press the power button to wake it. By ticking this box you will see that everything is fixed the way it should be. Good luck.

Let's continue to work together to resolve this issue so you can wake from sleep with those accessories.
The next step will be to make sure you're using the latest macOS software. You can use these steps to Update macOS on Mac

The only way to wake it is to click the power button in back of the monitor. I am using all Apple Accessories, Mouse and keyboard. Running Big Sur 11.2.3
