Imac keeps waking up immediately after being put to sleep

hi
firstly, apologies if this question has already been answered elsewhere in the community
i bought an imac in june of this year (running most up-to-date version of mountain lion), and normally when i leave it, i put it to sleep instead of shutting down
have had no issues in doing this until last night.. now, as soon as i put it to sleep, it goes into sleep mode and then instantly wakes itself up again
i have checked the battery on the mouse and the keyboard (98% and 100% respectively)
i have nothing plugged into any usb ports
any ideas on why it keeps waking up by itself and how to resolve this issue?
thanks

hello
thanks for your reply
i am new to apple products and to the community, and having read the community etiquette i apologise for not referring to the 'more like this' section before i posted - lesson learned
in respect of your advice, i checked the energy saver options as you suggested and the 'wake for network access' option was unchecked
interestingly, i have never had this issue until last night and i have made no system changes, downloaded or updated anything?
still a bit confused, will read through the 'more like this' posts and see if my answer lurks there somewhere
thanks again

Computer keeps waking up immediately after I put it to sleep

I've got a dual G5 running Panther and I put it to sleep when I go to work in the morning. Last night, I wanted to try out Tiger (yes, I know - I'm way behind the times) so I installed it on a FireWire drive and booted off it for a couple of hours to see how things worked. I then went back to my internal Panther drive, and noticed that when I hit "sleep", it goes to sleep, the screens turn off, and then for some reason I immediately hear the internal drives spin back up and the thing turns on again!! Why can't it stay asleep?!?

That is common and in my sleep tips;
"USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit."

SR MBP Wakes immediately after being put to sleep

Background:
I've recently been experiencing consistent random sleep failures with my Santa Rosa Macbook Pro. Whether I sleep via the apple menu, or close the lid, the MBP goes through its sleep procedure, then the split second that the MBP latch light begins to breathe, the DVD-drives makes its 'wake up' sound and the MBP powers back on.
Initially I thought my problem was related to an application. Firefox and MSN messenger seemed to consistently cause the problem. Then I found that it can still occur with neither open. It 'seems' that if I turn off my airport immediately prior to sleeping, the MBP will sleep without problems. Sometimes if I turn it off, then immediately turn it back on and sleep, the MBP will sleep okay. This doesn't seem to work consistently.
I had also thought this might have something to do with my airdisk since it's been suffering the (well-documented at this point) problem where airdisks start giving "Unknown user, login [...]" errors. This doesn't seem to be the case though since the problem still occurs if I disable the airdisk agent and don't mount any drives.
NOTE: This doesn't seem to happen with my GF's MBP. It too is a 2.2GHz Santa Rosa machine on the same AEBS network.
*System Details*:
- Santa Rosa 2.2Ghz Stock Macbook Pro
- OSX 10.4.10, all updates installed including airport updates
- Gigabit Airport Extreme with Seagate FreeAgent Pro Airdisk attached via USB
Observations:
In my logs below, it seems that a successful sleep does NOT show the following lines in the system log. This might be related to having turned off the airport in order to get a successful sleep:

I have had the same problem you described for the past week. Very frustrating, also very dangerous. I got in from work today and my mbp had turned itself on with the lid closed, it was absolutely roasting hot, must have gone close to cooking it. Mine seems to be worse when its on power, did you guys notice any difference on power or battery?

IMac G5 (1.8 Ghz) Shuts down after being put to sleep

My G5 shuts down immediately after being put to sleep and shortly after falling into sleep mode automatically. I have reset the SMU to no avail. I have also reset the Energy Saver preferences to the default setting.I didn't have this problem prior to installing OS 10.4.11. Any suggestions?

To The Apple Discussion Boards!
Have you tried repairing permissions & restarting either from the Utility Menu or your Tiger Install DVD?

T61 resuming after being put to sleep

Almost every time i put my comp to sleep it wakes up, sometimes immediately and sometimes after some time.
I only put to sleep using Fn F4 because worried it will resume with lid closed.
Any ideas on a setting I could change or maybe a program waking it up?

Hello,
Could there be a program running in the background which periodically checks for updated content, such as an RSS reader or anti-malware program? If so, does disabling it before the sleep operation make any difference?
Regards,
Aryeh Goretsky

MBP wakes up after being put to sleep

Several times the MBP wakes up after it was put to sleep, the battery runs down and it overheats inside the bag. I don't have any idea what wakes the computer, could it be the motion sensor? What can be done?

My wife's MBP started doing this after upgrading to Snow Leopard. So, after six weeks of hearing her complain of it when she forgot to close the lid, (I realize it still wakes up with the lid down, but since she only unplugs it when she uses it, that hasn't been an issue.) she finally let me look at it. I found using her System Monitor that the active app was Dashboard. When I told her, she said "I haven't run that for months, that couldn't be it." But, persisting, I opened Dashboard to find that she had a clock that kept local time. With her permission, I killed the clock and her MBP hasn't woken up on it's own since.
So, try running System Monitor to find out what's running after it wakes up.

Hard drive wakes up immediately after being put into standby

I have an IDE disk which, till now, I used to keep in standby mode (it makes an audible humming noise when it's working which annoys me a lot :<). Today I noticed that after running `hdparm -y' on it, it would spin down but then it would immediately spin up again. I'm certain that the disk isn't being used and doesn't have any partitions mounted anywhere on the filesystem. Still, I'm unable to pinpoint the reason it's waking up.
Any ideas on why this is happening?
Edit: It appears that the disk gets into standby by itself after 10 minutes. I wish I knew where this value is coming from. O.o
Edit2: Those 10 minutes must be coming from `hdparm -S1 /dev/sdb'; maybe the hard drive has a lower limit in regard to this setting. :3
(I'm not sure what kind of information would be useful in order to troubleshoot this issue, but below are some bits I believe are relevant)

Here is what i get when i try that command.:
$ sudo hdparm -B 254 /dev/sdc
/dev/sdc:
setting Advanced Power Management level to 0xfe (254)
HDIO_DRIVE_CMD failed: Input/output error
APM_level = not supported
I tried other values also and its always the same error.
I just did another try with -y and the drive stayed in standby during ±40 minutes this time. The most annoying part is that is something that was not happening before I am pretty sure that it would stay in standby for days.
I also included my results for hdparm -I.:

My iMac keeps waking up the moment I put it to sleep

Alright, so every time I go to put my iMac to sleep it immediately wakes up. Like the screen goes off, you hear the fan power down, then IMMEDIATELY wakes right back up. I've seen Apple's troubleshooting guide for this and nothing seems to apply. I've unplugged my wifi printer entirely, "wake for network access" is off in my energy saver settings, iTunes is closed, Spotlight is not indexing, I've tried unplugging my keyboard and mouse, etc. I'm at a loss here, please help!

Take all the steps suggested in this support article. That's the starting point for any further effort to solve the problem. Skipping any of those steps may mean that the problem won't be solved. Note that, as stated in the article, the computer will not sleep if Internet Sharing is enabled.
Step 2
From the menu bar, select
 ▹ System Preferences ▹ Accessibility ▹ Speakable Items: Off
Step 3
Select
 ▹ System Preferences ▹ Bluetooth ▹ Advanced...
and uncheck both boxes marked
Open Bluetooth Setup Assistant at startup if...
Step 4
Reset the SMC.
Step 5
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you boot, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Safe mode is much slower to boot and run than normal. Don’t launch any applications at first. If sleep still doesn’t work properly, back up all data and reinstall the OS. After that, if you still have the issue, make a “Genius” appointment at an Apple Store to have the machine tested.
If sleep now works as expected, go on to the next step.
Step 6
Still in safe mode, launch the usual set of applications that are running when you have the problem, including your login items, one at a time, testing after each one. Some applications may not work; skip them. You might be able to identify the cause of the problem this way.
Step 7
If sleep is still working after you’ve launched all the usual applications, reboot as usual (not in safe mode) and test again. If sleep still works, you’re done, at least for the moment.
If you still have the sleep issue after booting out of safe mode, post again.

IMac won't respond after being put to sleep/turned off.

I've been dealing with this problem for a few months now. If I put my hard disk to sleep or turn my computer off, it doesn't respond when I try to wake it back up or turn it back on. It will make a continuous clicking noise (no there's no disc caught in it the CD drive) and the only way for me to actually restart is to run the Archive and Install feature on the install disc. If I try to simply restart it, I get a blue screen with a folder-with-a-question-mark icon where the Apple icon should be during loading. I've had to skip putting the hard disk to sleep at all but I do just put the display asleep, and it wakes up fine after that.
I've noticed a lot of crashes with Safari and other things like games recently too. I'm usually able to just force quit the program and restart it though. I have a Logitech mouse and an Apple USB keyboard that I use with it and I've tried unplugging and replugging those, as well as trying other keyboards/mice with it to see if it's a rare hardware issue. The only thing I haven't checked yet is the RAM that my boyfriend installed for me a couple years ago.
Although, I've noticed the last couple times I've had to do that, I've had to wait to use the install disc. If I do it too soon after it's stopped responding then my hard drive doesn't show up on the selection menu and the Archive and Install option doesn't come up. I have to let it sit a little while before I can do it.
I'm not at home at the moment to see which exact model/generation it is, but I have the one with the flatpanel screen and built-in iSight. I bought it back in June 2006. I'm currently using Leopard on it (not sure which version though).
Could one of my boards be worn out? Or could the additional RAM be causing problems? Any advice or suggestions are welcome. I'd like try checking everything I can myself before having to take it in to an Apple store. Thanks!

I bought it back in June 2006.
If it was purchased new, you are better off posting in another iMac forum. This is for the G4 iMacs with the articulated display arm and the dome-shaped base. It's not your fault--the forum labeling is, at best, non-intuitive and confuses plenty of posters.
Look at "About this Mac" in your Apple menu and note the processor type. If it says "G5" then your forum is here:

If it says your processor is "Intel," then your forum is here:

IMac turns itself on 5 secs after being put to sleep - I do not have EyeTV

After I manually put the computer to sleep it awakens after 5 seconds. I deleted my power preferences I disconnected all drives.
It just started doing this the other day after having the mac for 2 years.
Is their a process log to investigate what is causing it to turn on?

This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
Here is Apple doc.#303698 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.

MacBook Pro not waking up after being put to sleep

Hey everyone, got a weird question. I bought an external monitor for my MacBook Pro (late 2010, Lion). For the past few days, whenever I put it to sleep using the sleep command in the Apple menu, I come home at night and find that it woke up at some point, started collecting my Growl notifications and IRC messages and just sat there running all day. It's also pretty warm when I pick it up (I'd say about as warm as half an hour of Minecraft gets it, not sure how else to describe it). The monitor is being left plugged in all day, as is a Logitech Unifiying reciever for my house. It's also connected to an Apple Bluetooth Keyboard the whole time.
What the heck is going on? Anyone got a solution? Thanks!

The principle is this: whenever your MBP is involved in an operation that keeps it awake, your MBP will keep this command going - until you disable the process. For me, it's the application Printopia; if I have sharing disabled - which Printopia doesn't want me to do - it keeps my machine awake, until I enable sharing.
Your situation is going to take a little invesigation on your part, but I can guarantee you that it's not a system or hardware issue. Systematically, disable or enable functions - typically on Control Panel - until the process is resolved. There's no "wizard" to root out the problem.

Problem with turning macbook pro on after being put to sleep

My macbook pro is acting strange, if i put it to sleep after 50% battery and turn it on again i get a grey screen, then it turns off. if i use the power button again it boots up and tell me that the time and date is not accurate then it turns off again.

Try a SMC reset
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Z10 will not turn on- after being put to sleep with full battery

I turned my Z10 off last night to save the battery. It was freshly charged. I woke up this morning and tried to turn it on. Nothing happens, not even a light comes on. The thing is a brick. It won't respond to being plugged in. I got it brand new, I've had it for six months, and I only ever use the charger that came with it. I'm afraid it's completely toast. Unless this gets fixed I'll never buy another Blackberry anything, but it's doubtful they'll be in business long enough to make that call.
Any SOLUTIONS are welcome. Being without a phone is not tenable and a BUSINESS such as Blackberry who alleges to SERVE BUSINESS with their products should know this. I am seriously disappointed.

Turned on after holding all three buttons for half a minute. But I'm not convinced this is the end of its troubles. Definitely getting a Samsung after this- I've never had a problem with any of THEIR electronics, and they're not going anywhere. The big worry for me is I'll need to send my Z10 in and they'll no longer exist to fix it.

No battery after being put to sleep

When i wake my computer up from sleep or if I leave it alone for a while, when i go back i have zero battery left. Why does this happen, is it self-fixable?

some updates.
problem #2 seems to be fixed by using the suggestion elsewhere about unchecking the "automatically reduce brightness of display before sleep" option in the Energy Saver prefs panel.
however problem #1 is still happening, even though I have reset the power management (eg as suggested above). in fact it just happened again this morning (went to auto-sleep last night as battery went to 0%), and the white LED was not blinking at all. I thought it had died again, but on opening I pressed the power button quickly and it "woke up and restored".
I guess I am ok with this since there was no data loss, but cant seem to tell the difference when it is actually sleeping with no LED blinking, and when it has died (and needs to be restarted).
Is there some explanation somewhere about how the MBP turns off the flashing white LED when battery is really low? my old 15" G4 never did that.

MacBook logs out after being put to sleep.

In detail: having previously closed my macbook mid work, and gone off to do something else, I reopen it to be greeted with the black screen and "to access this computer..." dialogue as normal. I type in my password, hit enter, get a brief blue screen (of the apple variety) and then am confronted with the log in page, and myself logged out.
This only happens occasionally, but is very frustrating - as any unsaved work is lost and any normal "save?" dialogues appear to have been ignored.
My macbook is set to sleep when I close the lid, and has no timer set to log out.
Any ideas on why this is happening?
Thanks in advance.
