Auto power off delay mac

These are typical of an ageing battery which needs to be replaced. Like Like. Thank you. I therefore have to keep on top of all this information, something that I enjoy doing anyway. So why not share the information to help others? Some machines have set both, like my iMac have autopoweroff set by default to 1, but also standby 1, autopoweroffdelay , standbydelay and hibernatemode 0.

Like Liked by 1 person. For a desktop Mac normally , you have three sleep levels. When waking, memory has to be powered up, its contents restored from disk, and it is thus slower. The third option is very similar, but designed to comply with a European Directive — again, memory contents are written to a hibernation image and memory powered down.

Set a startup, wake, sleep, restart, or shutdown time on your Mac

There may be some additional chipsets which are powered down, beyond those in normal hibernation. With your settings, after the standbydelay period of normal sleep, your Mac will go into one of the two deeper sleep modes, in which memory contents are written to a hibernation image and memory is then powered down. This assumes that your hardware supports these modes. I currently still have womp set to 1, and ttyskeepawake as well. In normal sleep, yes, but safe sleep? Anyone know the optimal settings for secure sleep, i. High Sierra or Mojave.

Quote Apple: Quote bfleischer: When in hibernation mode, a portable Mac will wake up in regular intervals to broadcast its Bonjour services to a local Bonjour proxy even if there is none despite not being plugged into power or the lid being closed. Strange thing is that my MBP works fine at first, accepts the FileVault key, but then only crashes while reloading the previous state.

Another headscratcher is this: So standby seems to be a different thing from hibernation safe sleep. I wish you success: I have the feeling that sometimes, no matter what you set, the SMC tries to fit that with its idea of what it will or can do, so you end up with its behaviour even though that may not be quite what you wanted. This seems very model-specific. Mojave changed something again, actually a nice new feature in pmset. You now have a highstandbythreshold, which is set to 50 by default i. Instead of one standbydelay argument you now have two: What I noticed, though, is that this new setting seems to disable safe sleep standby a.

But there might be a solution: But this needs to be tested further. In case people are wondering: This is the problem with pmset and the Energy Saver pane: I have just got a Mac Mini, and am trying to solve some problems with it not sleeping.

The Energy Saver panel is as you show it rather than the older form which has separate sliders fo display and system sleep. I suspect it is means system sleep 1 minute after display sleep. I might ask you about my specific problem later. That explicitly states the various sleep timers in minutes.

That says System Sleep Timer minutes 1, which agrees with pmset. Which, on the face of it, makes the system sleep before the display does. System sleeps after 1 minute regular sleep , unless a running process is overriding that setting, and display sleeps after 10 minutes, so the display sleep setting is irrelevant, unless you have a process that is overriding regular sleep. Weird thing, though: My MBP still wakes when I open the lid. Thanks, Joss. This is the frustrating think about power management — ultimately, your Mac is going to do what its SMC says. What I have seen is this.

But if you then Restore Defaults, you get Sleep 1 minute, Displaysleep 10 minutes. And if you try to use pmset to set the Sleep time it complains if this is less than the Displaysleep time. I thought I had solved the problem at one point when it was working ok, but after a restart it went wrong again. But this does suggest since it was right for a while a software problem rather than something to do with a drive or other peripheral. I can tell things are wrong even with the display off by several clues. First of all, approximately every minute my external speakers give a pop or two and I can see the lights on a hard drive going on and off.

Second, I play music through a Squeezebox, which is connected through wifi. If the Mac is not asleep, the Squeezebox display shows date and time, but it goes dark when the Mac is asleep.

That makes for a very easy way of seeing if the Mac is asleep, especially as the Squeezebox is in my sitting-room and the Mac is in another room. I suggest in the first instance you strip your system down to bare essentials, with as few peripherals and external drives as possible. See if it sleeps reliably then. If a stripped-down system works OK, progressively reassemble it and see what makes the difference — it may be one of your peripherals.

At this point, you can type reboot and remove the USB device.

Another method is to create a bootable OS X image running off of a USB device and change the power management settings by using the pmset utility. To enable auto startup, run the following command in the terminal:. Go ahead and run the above command to enable auto start and then type reboot and remove the USB device. The last thing to do of course is to actually test this out on your Mac Mini. Go ahead and let the system boot up and then yank the power cord and then give it a few seconds before plugging it back in. You should see the Mac Mini automatically power back on after you plug the power back in.

I have bootcamp for Windows 8. I went into Mac OS X and checked the box. I wonder what Apple is running to do it, I would think it would be an nvram command or something.

I was almost in trouble in that but this site preserves me from that and helped me to cover the problem, that is why I like to take their support always. Is anyone aware of a utility that can do this, and how to set it so ESX executes it on every boot?

Your Answer

Seems like the setting has reverted itself now. Is there something that needs to be done to make it stick? Or is there something that would cause it to revert? On the Mac Mini, it looks almost as if this setting is cleared by the firmware during shutdown — the Mac Mini will only automatically power on if the OS did not gracefully shutdown and power off the system.

Before making the change I checked the existing value: B So I made one tweak to the invocation of setpci. Instead of clearing the entire register by setting the value to zero, one can set arbitrary bits using the value: Here, I set the least-significant bit to zero. Little tip about Method 3: Hi, thanks for this article.

Power Management in detail: using pmset – The Eclectic Light Company

The ubuntu way works!!! Just as you described, it works like a magic. Thank you again, that helped me so much! My current solution would be to shuddown all running VMs and than wait for power loss to occur. Hypervisor would die. What is the worst thing that can happen? What kind of write IO operations is hypervisor doing while not running any VMs? There can still be write operations happening even when there are no VMs running.

How to Change the Standby Delay

Administrator could still be making changes to ESXi host, config, etc. So, yes there can be IO operations running. So, perhaps something you may want to look into. Just for clarity. Problem is not how to talk UPS. Problem is how to put ESXi host software to state when it is no longer running halted but power is still on so SMC in Mac mini can detect loss of power and restart automatically. That actually initiates a shutdown of the host, once VMs are off, it shutdowns rest of services and then the host. Last thing it does is to shutdown syslog.
