I'm not sure if this is related to the current '
sleep' issue being discussed, but...
If I switch my monitor off using the power switch, it also powers down the integrated USB hub, which is undesirable for me.
To get around this, I use the nifty 'Wizmo' app from Steve Gibson to turn off the monitor. It works a treat.
Recently, within five minutes of being switched off this way, it's back on.
I have narrowed this down to having MC server running, with or without the main UI, behaviour is the same. Close MC and server, turn off the monitor, and it stays off until the keyboard is pressed or mouse moved.
Why would it do that?
