IMac shuts down when put in Sleep mode

Computer works fine but when I put it in "sleep" mode in shuts down and cannot be restarted without unplugging and starting over. Once started it works fine again until the next "sleep".
Anything I can try before backing everything up and heading for the Apple store ?

Disconnect all devices except for the keyboard & mouse if you have not done so.
Try this:
Change the energy saving options, to put the display to sleep and the computer to sleep at the same time.
Enable (check mark) put the hard disk to sleep when possible.
Lock the padlock.
Optional: Repair permissions &/or restart.
==============
Check your Energy Saver settings to make sure they are correct.
If your computer came w/a remote, test the remote sleep option to determine if your issue is repeated.

MacBook Pro shuts down when put into sleep mode

Every time I put my Mac into sleep mode (plugged in or not, charged or not), it shuts itself down, and I have to restart it. I just got it (brand new) in August, so I know the battery shouldn't be bad.
It's been doing this for about a week... I just changed to Snow Leopard yesterday, and downloaded the software updates and everything, but it still shuts down.
Anyone know what I can do (short of sending it to Apple) to fix this?

Okay, well I already used smartsleep.
It fixed the problem I was having, but now my macbook started having the same issues again this weekend. It's happened twice tonight in the span of 3 hours.
Do I need to uninstall SmartSleep then?
And here is the report I get when the macbook reboots:

Shuts down when put into sleep mode

Any idea why this is happening?
When my ipod touch locks itself or if I put it into sleep mode, it will not wake itself up with the press of a button - instead, it restarts (black screen with apple logo in centre).
It is only 12 hours old and was perfectly fine when running on the factory 1.xx software, it has only started happening since the 2.1 software was installed.
Since, I have Restored it through iTunes which performs another clean install of 2.1 and it is the same still
Weirdly, while it is connected to my PC through the USB cable, it behaves perfectly (waking up from sleep instantly with the press of the home button), but as soon as I disconnect it from the PC, it starts playing up again.
If I set the settings to never lock, it performs brilliantly which is annoying as I now have a taste of what this device can do, but I just cant put it into sleep mode.
Any ideas on what I need to do? Or is it a case of returning it to Apple?
Thanks for any response

Is the battery FULLY charged? If not, charge it and then see how it reacts...make sure Wi-Fi is off while you do this--I've noticed weird things when it's docked and plugged into my TV (with the new dock) and wi-fi is on--I get battery messages randomly and it eventually shuts down (even though it's plugged into a dock with power, that came from Apple and is the "latest and greatest"...)

Dual boot computer restarts by itself shortly after it has been shut down or put into sleep mode

Hello,
I have Toshiba Equium L40-14I (old) and dual boot Vista and Linux.
A few days ago I noticed that while in a Linux operating system and when I put it to sleep (suspend) it would do so, but then immediately come alive again. The same thing happens with the shut down option. In Windows Vista it is the same. It does shut down, but in a few seconds restarts again and shows the normal options of choosing which operating system I want to boot. The computer only stays shut if I pull the power cord (it has no functioning battery) or it I forcefully shut it by pressing the power button for a few seconds.
So far I tried this:
- BIOS: 1. Changed to default factory settings. 2. Disabled wake-up on LAN and disabled wake up on keyboard.
- Device Manager, Network adapters, NIC, Properties, Power management: unticked the option that allows the adapter to wake the computer
- Device Manager: all drivers seem to be ok
- Virus scan: although this is probably not the issue as it happens independently of which operating system I am using. I have not installed any strange programs.
- I started from the Safe mode and then shut down. Same thing happened: it restarted automatically after a few seconds.
- Disabled automatic restart on system failure. It didn't help.
English is not my first language, sorry for the perhaps unclear way of describing this issue. I would appreciate any help. Thank you.

You have done just about everything I can think of. You didn't mention doing a System Restore. If you haven't done one or even if you have, do a System Restore back to at least sometime before this started happening. If the first one doesn't work, try a different restore point and do it again. If that doesn't work, you need to consider a full HDD recovery to out-of-box condition which procedure is fully covered in your User's Guide. I'm sorry I don't have a link for it but yours is not a U.S. machine and this site is for U.S. machines. It appears to be a U.K. model with support covered by THIS site.
BTW, I wish the native Americans who post on here did as well as you have so you have to make no excuses for your English.

10.5.7 Shut down when put to sleep

I updated my macbook pro sr to 10.5.7 today and noticed that when i close the lid, it shuts down after about 5 minutes. My battery is about brand new with under 60 cycles on it. I am wondering if anyone else can verify if this problem is only mine or something others are dealing with. I am sure that this started today after the update, as I had the computer asleep all day yesterday while at school. BTW, the mac is unplugged when it shuts downs. Thanks for any feedback.

Here is a log of what happened last night. It shut down randomly today also but there was no error report that I could find. I deleted the plist file as suggested but have not yet restarted the system. I am trying it now. Hopefully you have some ideas from the log. If you need more info out of it, let me know. What I have gathered is firefox is what is crashing. Just updated that same day as 10.5.7 I believe. Will see if it still shuts down with firefox off. Thanks for your help again Yang.

X230 shuts down when return from sleep mode

Hi,
a week ago I am facing with a problem - I am entering the laptop in sleep mode, just closing the screen, and when I open the screen (expecting that the laptop should wake up) it starts usual OS boot from scratch, not hibernate.
How to troubleshoot?
win7 x64
As I remember about 2 weeks ago I installed new VMWare player, latest power manager drivers.

Hi Barabas,
Welcome to Lenovo Community Forums!
I’m sorry to hear that your Lenovo ThinkPad X230 is restarting while you try to wake it up from sleep.
Go to control panel -> Power options -> Click on choose what closing the lid does (on the left side of the window) -> Select sleep -> OK.
If the above settings are as recommended, update your BIOS and Intel Management Engine firmware to the latest versions from Lenovo Support page. Enter your MTM number in the “Quick Path” and download the drivers.
Try reseating your memory. Try running the system with only one memory if you have multiple RAM in your system.
Hope this helps!
Best regards,
Mithun.

Macbook pro shuts down when put on sleep (OS 10.8.6)

I have a Macbook pro (OS 10.8.6), when I put it to sleep by closing the lid or explicitly choosing sleep option,it goes to sleep, but when I open the lid, the machine shutsdown. I have to press the power button for around 30 seconds to start the machine. In the logs I could find--Shutdown due to error code --79 and sleep failure shutdown.

Maybe some things to try check/try

IMac shuts down when using Safari 2.0.4

My iMac shuts down when I visit certain websites such as Pogo or video sites. Took it to the Apple store and of course the problem wouldn't replicate there. They kept it to check out the scripts and logs to see if they could find a problem - without success; although they did suggest my house is haunted. Brought it home and it quit again.
We thought perhaps we were getting interference from other wireless devices and unplugged our cordless phone which worked for a day. The computer always turns back on so its more of an annoyance than a real problem, but I'm baffled.
It also happened once when I was downloading from the iTunes store, but is most prevalent with Safari.
We have wireless internet connected via ethernet to an Airport Express.
Any ideas? Thanks.
iMac G5 Mac OS X (10.4.10)

Hi Barry -
Yes I do live near a ghost town (kinda) - Virginia City, NV. And I did tell any unwanted visitors to leave.
Actually, in the last year, they have replaced the Super drive, power supply, inverter and logic board. The only reason I'm not thinking power issues is that it only happens when I'm in Safari or iTunes. I would use Firefox except I've got java issues with that. I can (and do) use the machine for other things all day long without problems. I can use Safari all day long as long as I'm not playing on Pogo or certain video sites. Maybe Pogo is haunted?
It also doesn't happen on my husband's iMac on the other side of the house. Is there something that could cause enough interference to actually make the machine shut down? Oh, the antennae for the satellite TV and internet are on the roof directly above me, if that would have anything to do with it.
Thanks for your help.

HP Envy shutting down after going into sleep mode

Hi. I'm not sure where to post this so I'll try it here.
My laptop shut downs automatically when it goes into sleep mode. Not right away when going into sleep mode. Maybe like an hour later after going into sleep mode.
I'm not sure it's overheating because it never shuts down while I'm actually using the laptop.
Do you guy have any idea how to fix this?
Product name and number: HP ENVY TouchSmart Sleekbook 4-1115dx
Operating System: Window 8
Error Message: None
Any changes to your system before problem occurred: No

Hey Tecmo_SB_Guy,
I would suggest you take a look at advanced power settings. It can seem like the notebook is turning off when it is actually just hibernating. You can set it to not hibernate.
1. Windows key + Q to open the Search Bar
2. Type "power"
3. Click Settings under the Search Bar
4. Select Power Options from the results on the left.
5. In Power Options, Click Change when the computer sleeps, on the left.
6. Set the Put the computer to sleep setting so that it fits your usage best.
7. Click Change advanced power settings, at the bottom.
8. Expand Sleep and expand Hibernate after. If you want you can change the hibernation setting to Never by typing "Never" into the minutes field. See attached picture. You can do this for battery and/or plugged in.
9. Click Apply to save changes.
If you don't already shut it down periodically, I would suggest shutting it down at least 2-3 times a week if you use it daily. Leaving the computer running continuously can shorten its lifespan. Hard drive failures and motherboard issues are seen much more often on machines that are left running constantly. Computers get bogged down and run slowly when the memory is full. Memory only clears out and resets itself when the computer is shut down. Here is a link explaining more about memory accumulation and hardware aging.
I hope these suggestions help! Please let me know if you have any questions

IMac shuts down when a GPU incentive app starts

Hi guys,
My iMac a 24" EMC 2267 A1225 (Snow Leopard), is shutting down when i open an application that makes use of the graphics card. It started as a random shut down symptom for example when i was starting Adobe Lightroom. Now it shuts down once it boots on the login screen.
I booted into Safe Mode and tried to push the machine to its limits by opening many apps but the machine is not restarting so i am suspecting that this is an issue with the GPU.
I already installed iStat menus and the only thing that worries is me is the Northbridge 70 and NorthBridge Heatsink that goes up to 70-75 Celsious degrees.
I took it already to an authorised reseller in Cyprus and they have told me that this is a logicboard issue, i do not beleive this and a 700 euro replace is not an option for this 3 year old machine.
Please post your ideas on how to debug further in order to be sure before i go for a GPU replacement.

You may be in luck if you can find one over there...

Power Mac g4 freezes up when put in sleep mode

Hello. So the machine has had a lot of changes but the problem just started a couple days ago, before that I was going into sleep mode just fine with no problems. The problem is when the computer goes to sleep it freezes, the screen goes black but the fan and hard drive are still going and the light never turns to the flashing amber. What's more I'm unable to wake it up or use the keyboard restart command. The only way to restart or shutdown are the buttons on the tower. So I've turned power saver off and now have just resorted to shutting down when it's not in use but that's pretty bad in the long run.
Any ideas on what may have started causing this? Like I said it's beem working perfectly for a while now.

Did you install a USB 2.0 PCI card and do you leave bus-powered devices connected to it, when the computer goes into sleep mode? There have been many reported sleep issues associated with USB 2.0 cards in the G4s. What name is printed on the main controller chip (sometimes it's hidden by the card manufacturer's label)? The consensus of opinion is that USB 2.0 cards with an NEC chip tend to have fewer problems. Additionally, it's a good practice to disconnect the bus-powered devices from the card, prior to letting the computer go into sleep mode.

IMac Shutting Down when DVD player is in use

So, I know a lot of folks have been mentioning the new iMacs heating up and shutting down. I'm managing my heat issues okay to this point, and I use Photoshop, Illustrator, and InDesign every day.
But - the thing keeps shutting down when I try to play a DVD!
Anyone? This one has me stumped.

You are connecting the mini display port on the 2010 iMac to WHAT to try and get TDM to work?

Imac shuts down when not in use

I purchased my 21.5" imac July 9, 2011 with Snow Leopard. No problems for 1 month. Then about August 12th or so, my imac started to mysteriously "shut down" when not in use. I'll be working on it, then get up to go pour myself a cup of coffee or something...then I come back to my computer that has now shut off. It is NOT asleep...it is OFF. So I turn it back on and it is fine. This has happened a few times now within a week. Anyone else have this problem?
By the way, I am now running Lyon, as of August 18th. When the imac shut down, I was usually viewing photos or on the web.
thanks!

First thing I would try is to reset the SMC, it can help with power related problems. Shut down the Mac and unplug everything including the power. Press and hold down the power button for 10 seconds. Plug in the computer but be careful not to press the power button as you are plugging it in. Wait a few seconds and turn it on. Hopefully it won't happen again. There is always Apple Support. Don't let the problem persist until your free phone tech support has expired (3 months). I would also recommend using the iMac with an UPS, and at the very least, a high quality surge protector.
If you have MS Word or a similar word processor you could try enabling the autosave feature and set it to 1 minute intervals. Keep a document open and if you come back to the computer and it has shut down, you can look at the last time the document was updated and know what time the comptuer turned itself off. It could be useful in diagnosing the problem.

IMac shuts down when commanded to print

A friend of mine got a new Samsung color laser and when he tries to print his computer immediately shuts down. I uninstalled/reinstalled the printer software, ran FSCK which fixed some disk directory problems (probably from the unexpected shutdowns) and ran Cocktail, which did the cron scripts and cleared out the caches as well as repairing permissions. It seemed to be working normally, but he just called to tell me that the machine shut down again when he tried to print a document.
Anyone have any ideas about what's going on and what to do about it? Thanks in advance for your assistance.
PowerMac G5 2.0 DP Mac OS X (10.4.10)

Thanks for all the help.
I went back to his house tonight and we figured it out. I reset the SMU and installed the latest drivers, but the problem persisted. It was a little warm in the room, so we turned on a small fan on his desk next to the iMac. The next time we tried to print, we noticed that the speed of the fan dropped for a moment at the same time the iMac shut down. I then looked to where the equipment was plugged in and found one of those battery backup power strips with the printer plugged in to one of the backed up outlets. I moved it to one of the non-backed up outlets and the problem disappeared. I'm thinking that the printer was pulling too much power from the system and the iMac was shutting down due to low voltage. Just proves you have to check everything.
