I just received my new iMac and everything looks great and seems to work fantastic compared to my 9 year old Power Mac G4. I set in my System Preferences under "Energy Saver" for my Mac to go to sleep (Hard Drive) after 20 minutes. My Mac does turn the monitor off but it doesn't go to sleep unless I choose "Sleep" when leaving my computer.

My iMac wake unexpectedly from sleep mode then goes back to sleep 00:10-00:15 later. Yosemite is current.
Info:
iMac, Mac OS X (10.6.8)
just purchased a new 27" Quad core i5 and it takes about 5 seconds for it to go to sleep, and then makes a loud noise after.
My hard drive is also noisy, it whines and drums constantly.
I also have got yellow tint on all sides of the screen.
I live in NZ so if i will not get a new replacement, instead it will be sent away to apple which will take forever
by the way it is the older 27" (late 2009) version.
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.

It fails to sleep after the given time. Screen dims but I can still hear it running.
If I manually put it to sleep, it clearly makes noise (hard drive parks heads).
I assume that this could be a problem with my graphics card or RAM? I am trying to get some advice here before going to Apple since I work at home and I really can't afford lost productivity while they hang on to the computer for two weeks.

View 2 Replies View RelatedHaving some trouble with my iMac (the version right before the intel iMacs came out. further info can be provided if needed). Running all the latest software updates etc. When I put the iMac to sleep, it goes off as normal. With the usual white light. However, when coming to wake the iMac it won't respond to the keyboard or mouse. I have to shut it down at the power button, and then turn it back on.

Now i am experiencing a problem when waking my mac from sleep. about 50% of the time when it wakes it will immediately freeze which can only be resolved by a reboot. Could this be caused by this new drive being a "green" drive that conserves more energy when asleep by going into a slower state than a typical drive or is this a software issue?

Whenever I put my iMac to sleep it comes out of sleep immediately but the second time it goes to sleep and stays asleep.
I believe this is due to the bluetooth mouse I'm using however I have the setting to allow bluetooth to wake the mac turned off. Is there anyway I can pinpoint exactly what's causing this.
I have a C2D iMac about 3 years old, with 10.6 and all the updates. I have it set to go to sleep after 30 minutes of inactivity. Sometimes at night I will use it to listen to a podcast or watch a TV show. When I do this, it never goes to sleep. It's always still on when I wake up. The display will sleep, but not the computer. I can put the computer to sleep myself through the Apple menu, but it never sleeps due to inactivity.
I'm worried that having the computer on 8 hours a night due to this problem will shorten its lifespan. Does anyone have an idea of what may be causing it? Does it have something to do with webpages being open? I always have Safari open. It's easier to leave pages open than it is to go through dialog boxes and menus to create and delete bookmarks all the time.
Lately my iMac G5 doesn't go into sleep mode. I have it set to sleep after 20 minutes of no use.Also, I find the fan runs louder than normal.

iMac G5 20, Mac OS X (10.5.8), 20 inch 2.1 GHz G5 iMac
My iMac G5 desktop will go to sleep after I use it for about 20mn or so. I Can wake it but it will go to sleep faster and faster until I just give up. Then if a let it rest for a while I can come back and use it for another 20 mn or so before it start. Going to sleep again. Could it be heating up and my fan is broken?

iMac, Mac OS X (10.5.1)
My parents just bought a new Imac (3.4 Ghz/I7) which is running 10.6.8. and we cannot figure out why it won't go to sleep automatically. In System Preferences/Engergy Saver we have set both the "computer sleep" and "display sleep" to about 5 minutes, but no matter what we do it keeps showig the screen saver and never goes to sleep. The "put hd to sleep" is checked, and the start screen saver is set to roughly the same amount... I have tried adjusting these settings, to no avail.

iMac drops wi-fi after sleep. Have had this problem for a few months now. Has Apple offered a fix because it appears that many users are having this same problem

My iMac does not sleep. The display does go to sleep but the computer itself does not, and as a result heats up like none other.
View 7 Replies View RelatedI have recently bought a new i7 27" imac and when the imac goes to slep it seems to crackle/buzz very very faintly.
I phoned apple who told me to do the following:
Turn off the imac.
Hold down ALT, CMD, and R, and then hold the power button.
Then still holding ALT, CMD, and R press the P key.
I have seen several threads on the Internet but never an answer to the noise problem Imacs seem to have when in sleep mode. We have an Imac, 27' 10.6.5 2TB bought this summer, in the bedroom which we use as a TV. When we go to sleep we put the Imac to sleep as well with the remote and the ZZZ on the screen. During the night however the Imac fan or harddisk starts to spin as if the whole thing is going to startup but then it winds down again and it does this every hour or so. It is so loud that it wakes us up. Some nights it does it some nights it doesn't. Before we actually had the screen come on too but now it doesn't do that anymore.

View 7 Replies View RelatedI have an iMac (20" 2.4 g, 3 gig ram, os 10.5.6) that has recently stopped waking up after a long night of sleep. I have also found that the mouse and keyboard become unresponsive if the mac does wake up. The mouse has power, but the keyboard does not show any sign of life. The mouse glows red, but when I hit caps-lock, the little green light doesn't come on. I have tried switching ports, but no dice. As I said, the USB port clearly is sending power to the mouse, but not accepting any input. When I restart, all is well on most occassions, but the problem has persisted, once or twice, after a re-boot.
View 1 Replies View RelatedI can't remember the last time my iMac running 10.5.6 went to sleep by itself. The screen goes off, but it never goes into full sleep by itself. Airport is turned off, I put my cable modem in standby, never sleeps. I read somewhere in another forum that this was a bug with 10.5.6. Is that your experience?
View 9 Replies View RelatedMy iMac refuses to sleep no matter what sleep preferences I set or even if I try to sleep it manually (apple>sleep). It doesn't do anything. The display doesn't even dim like it used to a week ago. I don't have anything plugged in but the keyboard and regular mighty mouse, and restart doesn't change anything either. The Apple store installed a new hard drive on the computer a few days ago, since the 1.5 year old one randomly crashed and died. So I don't know what kind of funky things they might have changed, I'm just wondering if there's any simple maneuver I can do to make it sleep like it's supposed to!

View 4 Replies View RelatedNine times out of ten, when I wake my Imac from sleep, I get a notification that Safari stopped my shut-down (?) and then a second one asking if I'm sure I want to close the open Safari windows. Also, if Itunes was open when I put the machine to sleep, it's almost always closed when I wake it up.
View 2 Replies View RelatedI ask because I'm using remote tap on iPhone to remote into my iMac when I'm away. It sleeps it and wakes it just fine remotely. But when it's asleep too long, remote tap will fail to wake it, and the only thing that will wake it is if I hit a button on the keyboard or mouse. Is there a way to just keep it in normal sleep(?) or something?
View 2 Replies View RelatedMy 27" iMac will NOT stay in sleep mode. I click sleep, it goes into sleep, then like 3 seconds later it wakes again all by itself. I have no other apps running.
Anyone else have this issue?
I'm puzzled! Here is a youtube video of the problem on my computer:

Has anyone had this problem?
I have a (reletively) new iMac purchased in Nov. 27" 3.06 Ghz 4 GB Ram. The machine sleeps on it's own overnight from non use and then when i get up in the morning I click the mouse and I hear the machine waking up, (harddirve, cd-rom, etc.) but the screen stays blank. This happens in OSX and Win7 doen't matter what OS is running so it appears to be a hardware issue. Maybe there is a firm ware update, or somthing. To use the machine at that point, my only option is to force the machine to shutdown and then reboot. If I reboot to fast, meaning if I don't wait about 5-10 seconds after the shutdown, then the machine proceeds to boot but without any visuals, the screen stays blank.
Should I just take the system back to the apple store? Will they grab the current image and put it on a new machine...
I almost always put my iMac to sleep every night. Ever since about a week ago it started waking up, and waking me up, in the middle of the night. And yes in that week I have tried shutting down and it still does it the next day.
I don't have any apps open that I don't normally, didn't change any settings i'm pretty sure.
I tried the list from apple that lists reasons it would wake unexpectedly and googled but nothing works.
My iMac goes to sleep and doesn't want to wake up. I have to restart the ugly white thing to continue using it.
