My iMac keeps going into sleep mode (at least that what it looks like) for no apparent reason.
By "sleep mode" I mean the screen goes black, the sleep light fades on and off, as if it were in sleep mode, and the fan shuts off. When I press enter, it turns back on and the fan turns on very hight and loud.

I'm having a problem with my PowerBook G4 where is goes into sleep mode at random times. Mostly when I am streaming video..or at times the fan comes on, it sounds super high then boom. sleep mode again. After hitting the space bar, it comes back on, but it'll happen again shortly after. I've played with the sleep settings
View 5 Replies View RelatedAs 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.
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.

Sleep Mode does not seem to be working automatically in Snow Leopard. It sleeps when activated from the Apple Menu but not when set to sleep in Energy Saver Preference Pane. The screen dims, goes black but the computer does not seem to sleep nor does the hard drive spin down. Anyone else having a problem like this? It was working fine in Leopard (just noticed this problem now, but have had Snow Leopard installed for a couple of weeks and never noticed it)
View 5 Replies View Relatedafter having installed Leopard, my Mac doesn't go to sleep anymore. When I activate the sleep mode, it begins to "shut down" and the fans begin to blow. Normally, shortly afterwards it would sleep, but now the fans blow and blow and blow and nothing more happens. Using the mouse wakes the Mac again.
I installed two SSD drives into my 27" i7, one in the SSD location and one replacing the optical drive. So I have two SSD's (128GB + 256GB) and the stock WD 1TB drive.
My issue is once I put the machine in sleep mode, the iMac is ejecting the SSD's. If I boot off of the hard drive and then put it in sleep mode, I will drop both SSD's. If I boot off of one of the SSD's and put it in sleep mode, the SSD that was used for booting will not be ejected, but the other one will.
Anyone else running multiple SSD's (not in raid) and is having the same issue? I am beginning to think that I will have to live with just one SSD as the boot drive (which is not the end of the world). Or, cough up an extra $540 (not likely) for another 256GB SSD and raid 0 two of them as boot drives.
My iMac G5 (rev A) shuts down immediately after i put it to sleep mode after just starting up the computer. The longer the computer has been on before I put it to sleep, the longer it takes for the computer to shut down while in sleep mode. I already did the hardware test and it said there were no problems.

View 1 Replies View RelatedMy iMac G5 (OSX 10.4) starts up as normal, runs for about 5 minutes and then automatically goes to sleep. It will wake up if prompted, but every time it goes back to sleep in seconds. If left in sleep mode for a few minutes it will wake up again for 1 � 5 minutes before once again automatically returning to sleep.
It is definitely not due to hot corners. I changed the power saver settings several times, restarted and also reset the SMU but with no luck. I�ve also ran an apple hardware test which got the fallowing error code: �2FAN/4/8: CPU Fan�
Anything else I can try besides taking it in to an Apple service provider?
My iMac is some 2 years old and have never had this problem before but twice in the last week it has failed to awake from sleep mode and I have had to hold the start button to 'wake' it up. It then goes through the usual procedure that transpires afte 'logging off'

How can I get my iMac to stay asleep?
View 1 Replies View RelatedMy iMac will not come out of sleep mode and if it does it takes a really long time to do so. I've looked at several things in other forums and it seems to be a Maverick issue. However it only started about a month ago and most people have had this issue since the release of Maverick. I also read to use the bluetooth keyboard and mouse instead of a USB one. That also did not fix the problem. So I am at a standstill ...

I basically want to keep it asleep as much as possible to save on electricity, since I am not home about 10 hours of the day and asleep for the other 7, makes no sense in draining all the electricity. I was hoping someone could lead me to a small piece of software that allow this to happen.
I am new to the IMac experience which I have to say so far I love it but I am having 2 problems.
1) Every time my computer goes to sleep I lose wireless connectivity and I have to log back in where as my other computers I dont have to do this it signs back in automatically
2) Some how I lost Spaces from the icon bar at the bottom of the screen and can not figure how to get it back down there.
First, sorry for the longer post - I have to explain everything. I just bought a 24-inch iMac, Mac OS X 10.5.7, 2.66 GHz Intel Core 2 Duo, 4GB, 1067 MHz DDR3. I also just bought an uninterruptible power supply (UPS) from CyberPower. Everything's great, but I still have this one question which is bugging me. What happens when my iMac is in sleep mode and the power goes out? I have set the settings so that my iMac shuts down after 10 minutes of "battery" (UPS) usage, but I am not sure if it will do that when in sleep mode? The UPS is connected to my iMac via USB cable so that they communicate to each other in the case of the power outage, etc. This is what somebody wrote elsewhere on this topic: "Using the Deep Sleep widget, I've worked around this issue: I changed the default sleep behavior to Safe Sleep (hibernation+sleep).When I'm on the grid, my computer will now safe sleep after 3 hours of non-use. If I go off the grid and onto UPS while the MP is awake, the Energy Saver preferences will safe sleep after 1 minute. If for some reason this doesn't occur, Energy Saver will invoke a shut down after 5 minutes. If I go off the grid and onto UPS while the MP is safe sleeping, no big deal since contents are written to the HDD and RAM with this configuration."
I've downloaded the Deep Sleep widget and am using it now. Obviously, the user up there is using a MacPro, and not an iMac, but it should work the same. So, I am not concerned about losing data, and blah, blah, blah... what I am most concerned about is my iMac not working properly because it wasn't shut down properly. I know that there is a very low risk of this happening, but I've spent big bucks on this iMac and I want to make sure that it is shut down properly 100% of the time, if I can help it. If my iMac loses power when in deep sleep, will it be ok? Obviously, I am still using the UPS in deep sleep, but that UPS (battery) power will not last long and will shut down. I am going to turn my iMac off when I don't plan on using it for several days, but if I'm just out and about and the power goes out and my iMac is in deep sleep, will it be ok with the power going off? I contacted CyberPower and this is what they had to say after a long back-and-forth. "You will want to use the deepsleep tool. I had the belief that sleep was the same as windows hibernation where everything is saved to disk. Since deepsleep will save to the hard disk, you would not lose anything when the power is lost when the battery runs out." Despite all of this, I wanted to hear what everyone else thinks about this, especially those of you who might have experience with this kind of stuff. What do the rest of you do when it comes to UPS, etc.?
The AirPort on my new iMac 21.5'' 4670 is having problems these past couple of days. Every time I put the machine to Sleep and wake it up again, the AirPort cannot find any network. My wireless is fine and there are other wireless networks the machine can detect when it functions well. I have to restart the computer to have the AirPort work properly again. I thought it was a temporary issue, but after repeating a couple of times, it seems to be very easily recreated. And sometimes the AirPort does not function even from a restart. I have to restart another time to have it work.
Does anybody else have the similar problem? I hope it's just a software problem that will be addressed in 10.6.2.
(I posted here because it never happened on my other Macs before.)
Is it possible to have an external HDD connected to an iMac or Mac Mini on a regular basis? I have a Power Mac G4, and it's always had issues with going into sleep mode when there is any external storage connected via the USB 2.0 ports (and I've put in replacement ports to try and remedy this, to no avail). The main problem is that once the system wakes up, it thinks you've improperly removed the device. Apple told me, way back, that this was normal and to just eject all external storage before going into sleep mode. Which is a pain, but looking at a new desktop Mac I would like to just get the tiny, base HDD and use a beefy external for all my media - unless this is still an acceptable norm with new macs.

My 2009 iMac will not go to sleep by itself. It will go to sleep when it's induced but not automatically. I have been through several Apple support documents on this issue and searched here and on Google but nothing they suggest like resetting PRAM etc., works. I have been through console to see if I can find any errors and the only thing there is a couple of entries related to my Targus Bluetooth mouse. I have tried disabling and uninstalling this, updating the driver etc., and it doesn't make any difference.
