Has anyone got to the bottom of the problem where a Mini won't wake up from sleep or even come back to life when pressing the power button? Or even refuse to reboot from the power button?

I've had some problems on my 2012 i7 (running Yosemite) trying to wake it up but someone I work with has failed to get her Mini back up at all - she took it to a Mac indy and they said there is no hardware problem and she's got it working for now but this scuppered her at a particularly critical time.

I think there seems to be a problem (must have been introduced recently) that if I have "Konsole" open (the app where you can browse all the logs - no idea what it's called in English), then I get various problems with BT after waking up. These problems lead to a full reboot sooner or later.
I've now made sure I close and quit it before I put the Mini (2012 i7) into sleep mode.
Also, as of recently, Mail.app has started to act up and crash while in sleep mode. I've disabled all power-nap features (it sucks the batteries from my BT-trackpad and esp. the BT-keyboard empty in no time otherwise).
Haven't had that problem for a while, though.
Maybe she can quit Mail before putting it into sleep-mode?
 
I have started to notice the same issue ever since a update was installed about a week ago. I see the progress bar that takes long to complete and then I have to wait for BT magic mouse/keyboard to work. Anyway to uninstall the recent updates?
 
I'm having the same problem. I've always set my Mac mini to sleep after 1 hr but since the latest security update about a week ago its shutting down and moving the mouse won't turn it on I need to push the power button so it's completely shutting down. I went back into sys pref and energy saving window and it still shows the same entries sleep after 1 hr so why is it now shutting down over night??

It only started doing this after the latest security update.
 
I manually put it into sleep mode most of the time (usually at night).
My problems seem to have stopped, though, since installing 10.10.4 (and making sure I quit the log viewer "Konsole" before entering sleep mode.
And quitting Mail.app really helps.
Though the mail-problems could also be because of the GNUPG plugin I've installed (and it trying to update itself during sleep-mode or at wake-up).
 
So no one else is having this problem? I'm noticing my Mac mini is shutting down in the middle of the night. In the morning I can no longer move the mouse to activate I have to physically turn on the power button. I change my mouse batteries and checked settings show sleep only after 1 hr. In the morning just the white light is glowing on the mini solid white, once I turn on the power button it comes right on and mouse works right away.

I unplugged the entire power and waiting 10 mins rand re plugged so I'm going to see how it works tonight. If I wake up and it's still shutting down what else can I try?? My energy settings are still the same sleep after 1 hr.
 
Oh great thanks for the link now it makes me so Leary to do any updates when they mess up my settings.
 
This seems to have improved in 10.10.4 - I've managed to wake it every time although sometimes it's slow.
 
I do have this problem with my mac mini late 2012 using the default setting, does not even wake up from sleep, but am not sure whether is it due to changing from hdd to ssd that result in it. I have then change the setting based on this https://enotepaper.wordpress.com/2014/11/26/enable-hibernate-mode-in-yosemite/, even though it do wake up from sleep, but after a certain time(roughly 10mins), mac mini suddenly reboot and prompt with an error.
 
Ok some news here for late 2012 Minis - there is a firmware update released last month - this seems to have consistently sorted my 2012 Mini as Apple says it "addresses an issue that may prevent a USB keyboard from being recognized after the system wakes from sleep". Although my problem was it not waking at all - but so far it brings up the login screen now OK.
