OS X :: What Triggers Mac To Sleep
May 25, 2009
Is there something that indicates activity/inactivity, and actually "triggers" a Mac to go to sleep?
For example, if I am:
[1] copying files between my MB and MBP or iMac over my airport network
[2] downloading a movie off iTunes, or
[3] ripping a backup copy of a DVD I own using Handbrake to view in iTunes
These are all tasks that may take a while -- as in, I que them up, then go do something else while the Macs work. Do I need to adjust my energy saver preferences to "never so that the Macs don't go to sleep while working? Or is there something that tells the Macs they are in the middle of a file transfer, iTunes download, or DVD rip, so that they don't fall asleep mid-stream?

Sometimes, my MacBook triggers the key "" automatically. I just leave my MacBook for a while, I see thousands of \\\\\\\\\\ at the textfield which is on focus. When I press the "" key, it stops. I think my keyboard got some problems....do you think I can pick up the "" key myself for checking? Mine is a MacBook Unibody.

In tiger you could easily disable safe sleep and remove the sleep image file but in Leopard this seems to have changed. Yes you can disable safe sleep & remove sleep image files but only temporarily. As soon as you restart or change energy settings back to default, leopard automatically reverts the safe sleep settings to default and starts creating an image file again
Is there no way to permanently disable/remove these?

I leave my Air on pretty much all the time, and put it to sleep while moving around etc. Sleeping it disconnect the Airport connection - which if very annoying. At a desk I've just been dimming the display all the way off in order to keep my connection.
However, I recently noticed that by setting a "sleep display" hot corner, my network connection is maintained.
I have 2 questions:
1) Is sleep display equivalent (functionally) to simply dimming the display all the way down?
2) Is there a way to either set up a shortcut to sleep the display (other than a hot corner) and/or set it so that only the DISPLAY sleeps after 'x' minutes?

I set the MBP to sleep in 10 min through the Energy Saver pref with the option to sleep the hdds. When it's about to sleep the screen dims, then turns black, then the sleep light comes on but does not blink no matter how long I leave it. The blinking only happens when I close the lid or when I select the Sleep option under the Apple logo. Is that normal behavior?

I have a macbook pro 13" early 2011 and I'm se as shown in the pictures (since i upgraded to os x yosemite) . It happens after display sleep or computer sleep on login not on boot up .I've noticed that i run out of ram when the problem appears (only 15MB RAM available out of 4GB), though i doesn't happen every time . I've talked to service and told me its either motherboard replacement or because the ram isn't enough (gpu shares with main ram) so maybe i should try upgrading ram. URL....

I have torrents going all the time. If the computer goes to sleep, the internet disconnects, so they stop. Display sleep wouldn't disconnect though. Is it OK to have computer sleep on "never" but keep display on "15 minutes"? I don't usually even leave the computer on overnight.

I am running Mac Mini as a home server (turns out to be not a great idea, btw), and even though I set the preference to never sleep or shut down, it does go to sleep when there is no activity for long time. Since I am using it as home server, it should stay awake all the time or at least wake up from sleep when there is incoming ping from other computer, but it just goes to sleep.

Sleep seems to have stopped working all of a sudden on my recently upgraded iMac. The only thing I remember doing was repairing disk permissions and changing a few iChat preferences.
The console shows the following;
kernel Sleep failure code 0x00000000 0x11000000
A reboot does not clear the condition

iMac (24 inch Early 2009, 2.93 GHz Core 2 Duo, Lion 10.7.3) randomly goes sleep. No hot corners, never sleep setting. It seems it goes to sleep more often when CPU is busy and graphic intensive jobs running (videos, gaming). I cleaned up air ways by vaccume, but it did not help.
Temp monitor showed
CPU 55C
power supply 95C
northbridge 89C
graphic processer goes up to 86C
when it went to sleep for no apparent reason./private/var/log/kernel.log says "Previous Sleep Cause: -100"

Recently I've started connecting my 2.5GHz Intel Core 2 Duo (pre-unibody) Macbook Pro 17" to an external monitor (via DVI).
Since then my computer goes into Safe Sleep instead of Sleep (it's plugged into power).
This is an annoyance I'd rather avoid because even if all programs relaunch:I have to wait for them to launch (longer)Programs like Excel seem to have been quit in an unorthodox fashion: when it starts back up I get an error notice that it was shutdown inappropriately & the doc which reopens is a rescued version of the doc I had open before the safe sleep.

I have a late 2008 15" MBP, and I often leave it playing videos while I go to sleep. Lately, it's stopped sleeping the display and/or going to sleep (depending on whether something's downloading in the background) after the video is finished, which is quite annoying as the screensaver's glare normally wakes me up in the middle of the night (and it's probably not too good for the display either).
Before a few weeks ago, it would quite happily sleep the display a few minutes after the video (in Front Row or otherwise) finished playing, but it's now consistently ignoring the sleep and display sleep settings (which are all correct). I even set the display sleep timer to 1 minute, waited without anything happening in the background, but nothing happens.
Anyone have any idea how to get the timers to work again?

As of last night, my MBP started acting very strangely. After entering my username and password, it would enter the desktop for a short period of time and then kick back into sleep mode; the screen would turn back to black. Sometimes it will let me stay on the desktop for a long time and other times it will hardly let me stay on the desktop. I called apple support and they had me start the computer in safe mode; even then it occasionally kicks me out.
The tech guy said that it was a "strange software issue" and not a hardware issue. I thought it was a hard drive issue; my hard drive makes an odd sound when it unlocks (a grinding sound), but it has been doing that for quite some time with no issues. I tried to reset the SMC and it didn't do anything.
How should I remedy this problem? Is this a hard drive issue? Hard drive failure? Has the grinding sound finally caught up with me? I am running OS X; not leopard or snow leopard. I know I need to upgrade, but this shouldn't be happening.

I have a Mac Mini running Snow Leopard Client that I use as a HTPC and also as a fileserver for the Time Machine backups from 4 other Macs in my house. It is connected to a Drobo. I run it with no keyboard or mouse attached (I use Screen Sharing to control it). I have the Mac Mini set to sleep after 5 minutes of inactivity, and I have it set to "Wake for Network Activity".
For some reason, my Mini never goes to sleep. Is there any way to tell what is keeping it from sleeping? I'm hoping there is a console log or something that might tell me this info. I know it isn't the Time Machine backups from the other computers... even if I shut down every other machine in the house, it still won't sleep.

I have an older Mac Pro, quad 2.66. Running 10.6.5, Bluetooth keyboard, and magic trackpad. My computer stays on all the time and won't sleep by itself. I have it set to go to sleep after 15 minutes, but it doesn't. I've tried unhooking the printer, external hard drive, etc, but still no dice.

There are times when my iMac will wake from sleep for no apparent reason. Sometimes, several times a night. The glare from my screen often wakes me. If I get up and select Sleep again, it performs normally but may wake up again. I have "Wake for Network Access" turned off, so that shouldn't be it.

With OSX 10.6.4 my 2.66 GHz iMac will not stay asleep. It will wake up even though the Wake for Network Access box is NOT checked in System Preferences. Why is this? This happens every night.

I'm using a 20 inch iMac (iSight) and at night, I leave it to encode my DVD's.
I was wondering, is there someway to put the screen only to sleep and not the full machine? It is possible via the Energy Saving preferences but I don't want the screen to sleep all the time, just at night when I want it to.
Is there a keyboard shortcut or something similar that could to this?

It used to go to sleep without any problems after 20 mins or whatever I had set it to, but recently it won't do it. I repaired permissions, zapped the PRam and turned off my 3rd party screen saver but still no change.
