PowerPC :: IMac G5 Shuts Down During Sleep Mode

Nov 30, 2006

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.

PowerPC :: Ibook G4 Shuts Down When Put In Sleep?

May 25, 2010

I have an ibook G4 14" 1.42ghz.I have it plugged into a power adapter almost always. It has been plugged in in both instances/I recently put it to sleep and when I return anywhere from 15 minutes to a couple hours it is shut down. I have a heck of a time getting it to power on. It took me several times, anywhere from 3-6 times to get it to turn on.

When I turn it on it goes through the usual loading procedures and after loading a window pops up saying the date and time are wrong and could cause applications to act erratically. The date ends up being 1969 and sometimes the time is wrong.

I have fixed the date and it still happens.

I don't know if this has affected or led to this but my battery has been shot for a couple months now and occasionally (probably 1-2 times a day) the power adapter (a cheap copy of apple's) would become unplugged from the laptop prompting the message stating you are on reserve battery and that the computer will go to sleep soon.

Does anyone know what is causing this? How much would it cost to fix it?

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.

PowerPC :: Screen Turns Bluish After Sleep Mode

Nov 24, 2006

I have a little problem with my last generation 12" Powerbook G4. Sometimes, after I wake it up from sleep mode, the screen has a kind of blue tinge to it, as if there was some blue transparent plastic stuck to it. After I reboot, it's just fine.

PowerPC :: Unable To Charge The Ibook In Sleep Mode

Feb 25, 2007

I was wondering if anyone would be able to help me or if anyone is having the same problem as me... Since 16th Feb I have not been able to charge my ibook in sleep mode. Every time you put the ibook into sleep mode while the power cable is connected the ibook goes to sleep for a second or so and then wakes up again... If the screen is shut it just continuously keeps repeating the process...

I would be very grateful if anyone could advice me on what to do or recommend any diagnostic checks i should do to rectify the problem...

PowerPC :: G5 Extremely Slow To Respond After Sleep Mode

Oct 6, 2009

Just picked a second hand g5 up which runs like a dream! One thing I have noticed recently after putting the machine on sleep is that it takes forever to respond after been woken. The display and desktop come on instantly but when I click a program all I get is the beachball, the hdd doesn't appear to spin up. Then about 5 minutes later you hear the hdd spin up and away we go back to normal. It doesn't do this all the time though!

PowerPC :: G3 Hard Drive Spins Up And Down Constantly In Sleep Mode?

Aug 21, 2009

I put it on Craig's list so wanted to wipe the drive and figure I'd play around with OS 9 a little just for fun. While in OS 9 it prompted me to upgrade the firmware on the DVD-ROM drive. I thought that sounded like a good idea since it makes some terrible noises when a disc is in... anyway, I did the firmware upgrade and everything went fine. That's the only real change I can think of that might have contributed to this new issue.Anyway, after that I put 10.3 on it again (I had 10.4 on it before) and it wouldn't sleep correctly. Everything looks like its going to sleep ok, then the hard drive spins up, then back down, over and over again endlessly.

PowerPC :: Unable To Wakeup From Sleep Mode / Light Stops Blinking?

Sep 4, 2006

Tonight I came into my office and my PowerBook was sleeping. I have an external display and I usually turn my display on and wiggle the mouse (after I turn that on) and nothing happened. I looked and my display was still in standby mode, my wacom and eye tv had the same behavior. The powerbook light stopped blinking (I heard the drive wake) and then nothing. Nothing happened still. I opened the lid, hit the power button and still nothing. Held it down, and nothing. I ended up having to take the battery out and then I started the machine. Since then I've rebooted twice just for fun and since then the below screenshot shows that the "Jessica's Computer" window keeps popping up.

Two questions:
#1 What could have happened or what does it mean when the powerbook is sleeping, then wakes but never really wakes and just shuts off?

#2 What is up with that window opening as though this is some sort of start up program you'd find in windows?

Specs: Powerbook 1.67 ghz second to last rev...rev D I think. 1.5 gig ram. os 10.4.7

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.

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.

PowerPC :: IMac G4 Hangs On Grey Startup Then Shuts Down

Sep 12, 2010

My iMac will chime, then hang on the grey apple screen with the spinning gear. After a few minutes, it shuts off. Tried resetting Pram and all... Did not work. I troubleshooted using another website, and found it to be an I/O Error. The issue is I need to reinstall the OS, however, when I boot the install CD it hangs the minute I click the mouse or keyboard.

IMac :: SSD Drives Being Ejected When In Sleep Mode?

Sep 17, 2010

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.

Hardware :: IMac G5 Automatically Goes To Sleep Mode?

Mar 5, 2009

My 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?

IMac (Intel) :: Will Not Come Out Of Sleep Mode On OS X Mavericks (10.9.4)

Aug 31, 2014

My 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 ...
