IMac waking up at night

For the past week or so my iMac has been waking up from sleep in the middle of the night, and I don't know why. Other people are reporting the same issue with their new 8-core Mac Pros running Leopard, but I'm running Tiger on a G4. Could it be last week's release of OS updates (e.g. QuickTime and/or iTunes) that is the culprit? My computer is networked with a G4 PowerMac running Leopard, but that machine doesn't seem to have this problem. Any suggestions?

Hello and Welcome to Apple Discussions.
Try resetting the SMC:

Note: Sweet Patootie Pie, this doesn't apply to you as the iMac (Flat Panel) doesn't have an SMC, although the next step may be a PMU reset.

TS1367 I put my iMac to sleep last night and today it will not power on? I have check all cords and outlets and they are fine. What's going on?

I put my iMac to sleep last night and today it will not power on? I have checked all cords and outlets. What's going on?

James did you find a solution? Last night my daughter put her Macbook Pro to sleep and now it won't turn on or charge? I think it is not charging because the light does not come on. We charged mine and the light came on and worked so it is clearly her computer. Help!!!

IMac waking from sleep several times at night

For some reason my iMac won't stay asleep. This is starting to bother me because my iMac is beside my bed and it wakes me up when I hear the hard drive spin back up. I counted at least 4 times last night that I heard it wake itself up (and me). I usually sleep my iMac at 10:00 pm manually. Here is log entries from console the first of 4 times it happened last night:

IMac waking up..console says hijack!

Hey...
My iMac has been waking up allot during the night for the past few months... Someone when I come to it I find it not sleeping at all. I was told a few weeks ago when I catch it go to the system log.. I did that today and am now really worried its some sort of Mac Virus or something.. I could be wrong its just the name freaks me out.
26/06/10 2:07:44 AM com.apple.launchd.peruser.501[88] (com.apple.AddressBook.abd) The following job tried to hijack the service "com.apple.AddressBook.abd" from this job: [0x0-0xd9fd9f].com.apple.AddressBook.abd

Address Book appears to be trying to gain access to the CPU or a datafile unsuccessfully. Since it's AB that's involved you might consider removing the referenced preference file and replacing it with one from a known good backup.
If you have AB always open, see what happens if you quit it.

IMac waking up everyday @ 6 p.m. CST even when shutdown

Hello all
iMac (Intel) Mac OS X 10.5.2
Question: My iMac has been mysteriously waking up everyday at 6 p.m. CST even when it is completely shutoff. I checked the Energy Saver for schedules but nothing is enabled.
What could explain this?

Hi Pierreiphone
First reset the iMac's SMC (System Management Controller) exactly following the instructions in the following link.
http://docs.info.apple.com/article.html?artnum=303446-en
Then in the "Energy Saver Preference / Options" be sure that the box "Restart automatically after a power failure" is unchecked, just in case something else is interrupting the iMac's power at that time.
Lastly are you using elgato iTV?

Late 09 iMac waking HDDs Help

Hi,
Ever since updating my late 09 iMac to ML it seems to be waking all HDDs attached including the internal drive every two or so hours while asleep. I am unsure what it is doing when it turns them on but it can wake me up and I know it isn't very good for all drives to keep doing that. It seems like its acting as if its in Power Nap which is impossible.
What could be cauisng my iMacs phantom HDD behivour and how can I stop it doing it?
Thanks

Is the computer screen staying off when it wakes?
If so what your experiencing is "wake for network access" ironically there are threads on here where myself included are not happy that since upgrading to ML its not working properly for us.
Go to system preferences/energy saver and untick the wake for network access tab and this should stop this happening for you.

Imac waking itself up from sleep mode

i am very concerned about my imac it keeps waking itself up from sleep mode. i checked the prefrences and its not scheduled to wake itself up, do i have a virus?

OK jon,
We stil don't know exactly which iMac CRT you have but this is based on the 350 - 400 Slot loader and is from the service manual:
"Resetting the PMU on the Logic Board
Resetting the PMU (Power Management Unit) on the logic board
can resolve many system problems. Whenever you have a unit that
fails to power up, you should follow this procedure before
replacing any modules.
1. Disconnect the power cord and check the battery in the battery
holder (BT1). The battery should read 3.3 to 3.7 volts.
If the battery is bad, replace the battery, wait ten seconds,
and then reset the PMU (refer to the next step). If the battery
is good, go to the next step.
2. Press the PMU reset switch (S1) once on the logic board and
then proceed to step 3. Do NOT press the PMU reset switch a
second time because it could crash the PMU chip.
3. WAIT ten seconds before connecting the power cord and powering
the computer on. If the computer powers on, go to the
next step. If the computer does not power on, there is something
else wrong with the computer, refer to the symptom/
cure chart, “No Power” in this chapter."

IMac Waking Itself Up From Sleep

My Intel iMac has taken to waking itself up when I put it to sleep. It's happened once or twice before in the past, but over the past few days it seems to have become a regular thing.
I put it to sleep by pressing the power button on the back, and the around 30 minutes later it will wake itself up despite me being nowhere near the keyboard or mouse.
Any ideas what could be causing this and how I could fix it?
I don't know whether it's related or not, but my Aluminium Bluetooth Keyboard has recently been playing up too and keeps giving me a Connection Lost message.

Computer Waking Up at Night

Hi there,
Have a problem with the desktop waking up at least once every 10 days or so.
Checked all the necessary problem areas: powercfg /devicequery wake_armed returns NONE.
Wake computer options are all off for Scheduled Maintenance, Power/Multimedia, Ethernet.
Noticed the WindowsUpdate entry under Task Scheduler has "Wake the computer to run this task" checked.
Unchecking and OK (even without unchecking) on the properties dialog box will stall for a few seconds. Then there is an alert "task scheduler service is not available." This was restarted through the scheduler by (successfully) changing
the conditions for that on the TaskScheduler entry.
I suspect that Windows Update is waking the computer but the above doesn't constitute sufficient proof. Nevertheless, the irksome side-effect is that the OS doesn't appear to employ it's configured power saver options after being woken.
So it can stay on for hours (or days) without turning off. (Bear in mind the Power Saver conditions work when the computer is manually started.)
Any suggestions?

Looking at the Windows System Logs, the first thing of interest in the second wake-up was the following logged at 4:01:26 AM.
The system time has changed to ‎2014‎-‎07‎-‎27T18:01:22.500000000Z from ‎2014‎-‎07‎-‎27T16:25:06.322889900Z.
Change Reason: System time synchronized with the hardware clock.
There are 0x1 boot options on this system.
The boot type was 0x2.
---(usual boot up messages)---
The system has returned from a low power state.
Sleep Time: ‎2014‎-‎07‎-‎27T16:25:02.085474900Z
Wake Time: ‎2014‎-‎07‎-‎27T18:01:23.010360200Z
Wake Source: Unknown
Reset to device, \Device\RaidPort1, was issued.
Was the computer woken to adjust the clock? The BIOS doesn't cater for system clock changes.
As a matter of interest, what do the values of Sleep Time and Wake Time actually represent?
Is it total wake/sleep since last boot? In the above scenario the system was put to sleep at 2:25:04 AM, sleep for only 90 mins.

IMac waking up needlessly

I put the machine to sleep then a little while later I get this in the console:
'Wake reason GIGE - bonjour - conflict resolution'
...then it doesn't go back to sleep again.
What does that mean??
Thanks!

Hi William:
Take a look at the log files. Wake events (and the thing that caused the wake) are there.

IMac wakes from sleep every night at 8:00 PM but no wake time set.

My iMac (new fall, 2007) running 10.5.2 wakes every night at 8:00 PM Eastern day savings time. Before day light saving time started it woke at 7:00 PM. In the energy control panel "schedule section" the "start up or wake option" in NOT checked.
The exact same problem occurs in a mini Mac purchased last fall which is also running 10.5.
I applied the new firmware update to the iMac last week hoping it would correct this problem but it did not.
Does anyone have any idea how to stop these computers from waking at 8:00 PM every night.

Setting the wake time to 8:00 PM did stop the computer from waking up every night at 0:00 GMT.
See this discussion: http://discussions.apple.com/thread.jspa?messageID=7075146&#7075146
I view this as a work-around and not a fix. The Apple technical support representative, that I talked to, knew nothing about this problem.

TV remote waking up my Intel iMac?

This is really odd: in the last week or so, I've noticed my iMac waking up from sleep when I turn off my TV with its remote or when my roomie in the next room does likewise.
Has anyone else experienced this? Any fix for it?

You posted in the wrong forum. Since you have an Intel, you will need to repost in the Intel-based iMac Forums.
This area is for G5 iMacs which are an entirely different model than an Intel iMac.

IMac woke up by itself with clicking pattern. Folder with ? mark now. Can't see HD in Diagnostics. Dead HD?

Hi,
My iMac was asleep all night, but it woke up suddenly by doing a 6-click pattern. 6 clicks, then the sound of something whirling/winding down, silence, then 6 clicks again, sound of something whirling down, repeat.
Last month I suddenly heard my iMac making weird clicks whenever it woke up from sleep. I posted about the problem here. It would take longer than usual to fully wake up, and as it was doing so it'd make lots of clicking sounds before I could use it. Did Diagnostics; Repair Disk said my HD was fine.
I think the problem stems from someone borrowing my computer and using up lots of RAM (tons of programs open), which of course slowed down the computer, so his solution was to just hold down the power button to restart (found out he was too impatient to restart the computer the right way ). I don't know how many times he did it, but I guess 10 times total? Is this enough to mess up the HD?
One day the iMac showed the folder with a question mark on it. I put in my Snow Leopard install disc and ran the OS from it. I went into System Preferences and redirected the computer to start up from the HD (it had been blank, for some reason). Then it rebooted from the HD like normal. I started using the iMac again, and the clicking problem became only intermittent. Eventually the clicking went away altogether, so I continued using the computer, hoping the HD was still all right (wishful thinking). I did make disk copies using Carbon Copy in case I was wrong (I also let Time Machine do its thing every single day).
Today I woke up to the sound of my iMac clicking because it woke up on its own. Again, it was having the old trouble of waking like it did last month. 6 clicks. Wind down. Silence. Repeat. It gave me the grey screen for a few long minutes, then it gave me the folder with the question mark on it. I tried to boot from my Snow Leopard disk, but when I tried to re-direct the boot drive, there was no option for my hard drive at all like last time (just the CD and the network server). I tried entering Diagnostics, but again in the left pane there was NO option for my hard drive like last time, only the CD-ROM with the Snow Leopard CD in it.
Does that basically mean my HD is dead since I can't "see" it? Should I even bother taking it in to Genius? I'm probably going to be buying a new iMac tomorrow. I just hope my Time Machine and Carbon Copy backups will transfer all my files correctly. I've never had to do this before, so I'm pretty nervous about it.
Thanks!
P.S. My iMac is probably 4-5 years old. Purchased refurbished from a non-Apple store. I guess it's just time?

I put the HD back into my iMac's SATA sled and can view the contents of the drive without a problem, once again. The Disk Utility on the iMac indicates that the S.M.A.R.T. Status for the drive is "Not Supported," but that is probably because it is viewing the drive via USB from the sled.
If the drive was failing would I really be able to access it from my iMac via the SATA sled so easily?
At this point I am leaning on taking the whole MBPro, drive and all, into the Genius Bar tomorrow and hopefully getting back a working computer within a week.

My 2010 iMac doesn't want to wake up with the bluetooth keyboard nor mouse?

When I put my iMac to sleep at night, usually the next morning I cannot get it to wake up. I have all bluetooth devices attached and fully charged, but they just won't wake up the computer. Pushing or holding the power button does nothing. I have to cut power to it to get it to boot/reboot. All MacOS updates are installed. Thanks for any assistance.

One thing to check. Even though this defaults to on, In System Preferences > Bluetooth > Advanced.. button > verify that "Allow Bluetooth devices to wake this computer" is checked.
Also, don't turn off the keyboard or mouse overnight. They will "sleep" at low power. When waking the system, do a Physical click on the mouse or keyboard.
Regards,
Captfred

IMAC Wakes Up

My IMAC has begun "waking up" at night. It hasn't done this previously. My question is; Why is it doing this, and how do I stop it from doing so.
Thank, Terry

Do you have anything checked in System Preferences>Energy saver? Try resetting the PRAM and see if that helps. Please let us know how you make out,
