OS X :: Power Mac - Installed Leopard - No Sleep Mode

Nov 9, 2007

after 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.

Power Mac G5 :: No Sleep Mode Running OS 10.4

Nov 23, 2007

My old G5 dual 1.6 will not go into sleep mode. I had upgraded to 10.5 but several of my photography programs would not run so I reverted back to 10.4 by reinstalling the operating system and not wiping the drive clean. I now must shut down everytime or the G5 will get to the point that all of the cooling fans are running full speed and it will not go into sleep mode automatically. Any suggestions other than a clean install?

Intel Mac :: Power Off Or 'Sleep Mode'?

Jul 1, 2012

Is it best to turn off my 27" i7 processor iMac or put it into sleep mode when it's not in use? ie sleep or leave the house. Also the fan has just turned on, never heard it before. I am watching a video whilst converting another into mp4 format. Is that why?

Power Mac G5 :: Wake Up From Sleep Mode Causing Crashes

Oct 20, 2007

I've been fighting bad sleep crashes for over a year. Sometimes it would freeze when it started sleep, sometimes when trying to wake from a sleep. I've spent countless hours researching the problem, reading everything on the boards. I tried resetting the PMU, turning off Bluetooth, removing all USB, and all of the other suggestions. Nothing alleviated the problem. Last week I replaced the lithium battery on the mother board because it wasn't keeping the correct time. So far it is sleeping and waking perfectly for the first time in ages. No more freezes or jet engine fans. I have my fingers crossed. Power Mac G5 dual 2 GHz, purchased June, 2003

OS X :: Uninterruptible Power Supply (UPS) - IMac And Sleep Mode?

Jul 22, 2009

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.?

Software :: System Not Exiting Sleep Mode / Kicks Back Into Sleep Mode

Dec 29, 2009

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.

Permissions and this check show no errors, the only error sleep mode failure. Boot up is very slow as well as wake up when possible is slow.

OS X :: How To Get Sleep Mode In Snow Leopard

Sep 18, 2009

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)

OS X V10.5 Leopard :: IMac Keeps Going Into Sleep Mode?

Feb 19, 2012

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.

Mac Mini :: System Keeps Going To Sleep Mode / Preferences Are Set To Never Sleep

Aug 10, 2009

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.

OS X :: 64bit Mode Snow Leopard - Computer Always Boot Into 64-bit Mode If This Is Done Once?

Aug 28, 2009

I did a bit of reading on the internet, and it looks like most computers will not boot into 32-bit mode by default with 10.6. It appears that if while booting the user holds the 6 and 4 keys, the computer will boot into 64-bit mode.

Does anyone know anything about this? Will the computer always boot into 64-bit mode if this is done once? Will it even make a difference? Will the average user want to do this?

MacBook :: Waking Up From Sleep On Its Own After 10.5.5 Installed

May 28, 2009

I have a 2.4 Penryn black MacBook. It's been waking up on it's own, overheating and shutting down since I installed 10.5.7. This happened when I first got it, and I took it to Apple. At that time, seems the RAM wasn't seated properly. It hasn't been a problem again until now. Yesterday, it did it twice. The RAM seems to be seated properly. Is there a firmware update or something I'm missing?

OS X :: Mac Keeps Getting Stuck In Sleep Mode?

Feb 11, 2010

Second time since yesterday-My MacBook (White-2007) has been stuck in the sleep mode and the only way for me to get out of it was to force shutdown. (Pressed the power button for ~5 seconds.)

The white sleep light had stalled and was not blinking-Is this an indication of software problems, or that my harddrive is about to fail?

Imac Won't Go Into Sleep Mode

Mar 27, 2012

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.

MacBook Pro :: Won't Work With Sleep Mode

Sep 19, 2010

I sometimes forgotten to unplug the device before closing the lid. Such as when I'm in a hurry and close the lid of the MBP, only then realize that my iPhone is still attached.

I don't want to put unnecessary stress on the harddrive by it going to sleep, waking up, then sleep again just because that unplugging an USB device woke it up. I notice that this does not happend on my Windows laptop.
