None of these solutions work for me. When I use the command I get the response NONE but when I put the computer to sleep, then move the mouse, it wakes up again. I have disables wake from sleep for everything from the monitor, mouse, network, but it still won't go to sleep reliably, and will wake up seemingly at random.
Based on searching online about this topic, the correct response from Microsoft to any queries about this should be "Windows 11 sleep functionality is broken"
