Done everything, yet my Mac keeps shutting down when in sleep mode

I have reviewed all the topics here and nothing quite matches my problem.
When I put my computer to sleep, after about 30 minutes, it shuts down.
I have vacuumed the vents.
I checked Console for warnings (there are none).
I reset the SMU.
I reset the PRAM.
It is out of its warranty with Apple Care ... is my computer dying??
Any ideas what to do next?

My 3.5 year old 20” G5 iMac recently started doing the exact same thing! It does not seem to be heat related, and there are no warnings in the console either, and it was not part of the ones identified with possible power supply issues.
I’ve checked all of the preferences and settings, ran Disk Warrior and Disk Utilities, checked file permissions (all were OK). Mine only seems to power down after it goes to sleep (but not every time), never in the middle of doing anything. So far, I’ve only noticed it when some of my external fire wire drives are powered up, but that could be a coincidence.
I was beginning to think it’s some sort of software bug, but I suppose it could be a hardware fault with the logic board. But since you are having the same issue, maybe it is software afterall. My software is totally up to date, but it seems that I’ve only started having this problem after installing 10.5.6.
Here’s my thread:

How do you prevent the computer from shutting down when in sleep mode?

How do you prevent the computer from shutting down when in sleep mode and plugged in?

Thanks tjk.
Those are great suggestions and got me looking in places I had not considered before. Unfortunately, the problem remains. The System Preferences did not have the shut down option activated and there are no parental controls active on the computer.
Any other suggestions are welcome.

QOSMIO x870 shutting down when in sleep mode

I'm not sure if this is working as intended or not.
I was working with the ECO setting to put my computer to sleep after certain amount of time. Once it was asleep for a certain amount of time, it would go into a shutdown/hibernation mode. It turns back on in the state that it was in when it went to sleep.
Also, if I have a program running and lock the computer, it will act like this as well when there is sleep time set.
I thought that I would be able to lock my computer and run a download over-night, but when I went to my computer in the morning, my computer was shutdown/hibernating. It came back up to where it was, but it appears that it hadn't continued the download for much over an hour before shutting down.
I don't think that this is intended, but I may be wrong.
I'm still digging around trying to find settings in regards to this. But I have hibernate turned completely off.
Is there some way to set the computer so that it won't shutdown/hibernate when in sleep mode and/or a locked screen?
In the meantime, I'm trying setting the ECO settings to "Sleep :: Never" to try to accomplish my download without the computer shutting down/hibernating during the process.

Thanks tjk.

IdeaPad U400 shuts down when in sleep mode

My IdeaPad U400 shuts down when sleeping. All programs terminate.
I reviewed another poster's complaint about a similar problem several months. The response instructed the user to update the computer's drivers.
I have updated my drivers. My computer still shuts down regularly while sleeping. Please help!

Hi RuthAnne,
Welcome to Lenovo Community Forums!
I’m sorry to hear that the issue still persists even after re-installing the drivers as suggested in the previous posts, I also assume that you have updated the Video Driver(Win 7 or Win 8) & Chipset Driver (Win 7 or Win 8)specifically and checked if this resolves the issue.
If the issue is same even after installing the above mentioned drivers, please backup the Data in the computer to any external hard drive and perform OSRI (Operating System Re-Install) to check and confirm the issue is with the
OS (Operating System).
NOTE: If the computer is shipped with pre-installed operating System OSRI can be performed using the instructions in U400 User Guide click here, check the steps to perform OKR(One Key Recovery) on page 23.
Hope this helps!!!
Best Regards
Shiva Kumar

MBP shuts down when in sleep mode

I left my core i5 MBP 15 asleep during the day today with about a 85% charge. I opened the lid later this evening and the computer shut down and when I started it up, it only had a 58% charge. Please let me know what's going on or what I need to do. Thanks.

Tech. Support told me to send my laptop to them after too much of my time wasted. They were trying to make me install the Thinkpad Power Manager software and driver once again. They even said it was normal if your laptop shuts down after a few minutes or hours in sleep mode which is completely stupid unless the battery drained off and that's not the case.
And what's more important, my laptop was working faultlessly until I sent it to them for service. Then they changed the main board but they broke my LCD screen and caused the problem with Sleep mode. So I had to send it back, they changed the LCD with a 2005 HT14P12-100 when I had bought it in 2008 but they did nothing about the Sleep problem. And they want me to swallow that?
Ok, they'll collect it on Monday or Tuesday because I told them I was fed up and I didn't want it like that. I don't expect they'll solve the problem but I don't want it back until my Thinkpad works like it used to do before they put their hands on it.

Yoga 13 Shuts down when in sleep mode...

I've always used sleep mode at night and quite frankly most of the time instead of shutting down my yoga. I know thats not good after reading some here but wanted to share history in case that has something to do with problem.
Typically at night or when leaving office or just going to be off computer for a while I'll close the lid (which is set for sleep mode) and when I return I open it up, enter my password and I'm right where i left off. I have multiple spreadsheets or power points open so it's easier than shutting those down every time or even at night. But since yesterday, when I open it back up, it has shut down and has to start up from "off" vs sleep. All things open have to be recovered (xls, docs, ppt, etc) and chrome says it has shut down unexpectedly and asks if I want to restore tabs, etc.
What is causing this change and how can I troubleshoot it and fix it?
Help much appreciated.

Right click on command prompt and select run as administrator. That should fix it and allow you to type that line

Mac keeps shutting down

Hi,
this is a bit of an awkward problem – not sure if someone can help me out.
I work on a MacPro (early 2008) but have updated it with two hard drives (SSD) and 24 GB RAM. So it works pretty well.
The computer is connected to a battery back up because we have lot's of brown outs in my area. My computer battery got fried 2 years ago (after a black out) and I think I have a third party battery now in the machine.
Everything has been working fine these last two years but now my Mac keeps shutting down and tries to start up again without success. I tried to find the problem and tested a new external battery back up, which wasn't the problem. I check our electrical outlets. They seem to be OK, though the electrician found out that they weren't wired properly – so he fixed it. And it works fine for a week. During that week I unplugged the computer from the outlet so that the internal battery can drain. When I stopped doing that and left the cable in the machine over night, the problems came back and the Mac kept shutting down. So my guess was, that there is something wrong with the internal battery of the computer. The strange thing is that the Mac works fine when I plug it with an extension cord in an outlet downstairs. This is confusion since there might be really an electrical issue in our home (?)
Then two days ago I realized that my memory RAM shows up only 12 GB instead of 24 GB. So I took the RAM out, dusted everything and put the RAM back in. The Mac was back at 24 GB.
So far the Mac hasn't tried to shut down on it's own. The cable is plugged in in my office outlet; not the ones which worked fine downstairs but I unplug it over night; just in case. As you can see, there is a lot of confusion in finding the problem. Perhaps the shut downs were related to the RAM? I'm just concerned that the problems come back.
Has anyone a clue what the problem is/was. Has anyone experienced something like this before?
Thanks for you input.

I assume that you realize there are cheaper and now better FBDIMMs should you need to narrow down and find any that are offending?
Often heat and dust, and FBDIMMs run hot, age, go bad over course of time. New ones run cooler, that helps.
That you have now probably a 900W or higher, 1500VA UPS, and that you should not have to turn off, leave it on, shutdown or leave the Mac running, up to you.
Resetting the SMC and NVRAM probably done more than enough. USB devices are also able to cause erratic behavior. Been there and done that.
We also have a fair share of power oddities and UPS is a must - all my TVs and such have one, any electronics and floor lamps.
But you also want your modem, router, and important equipment on UPS too, and I found my old APC would interfere with modems and routers, my new-ish Cyberpower do not and work fine so I feel more protected (having had a modem problem is no fun, it was semi functional, semi not (illiterate) if you will (now have spare modem and router too). If you don't filter the RJ45 out of the modem, there can even be too much for the router or the RJ45 ports is what APC told me in a conversation years ago.
3,1 has been more prone to shutdown issues. So yes there are - some early versions of 10.8 for some, for others it was that they upgraded from 10.5 on and had never made a clean break esp. when Lion dropped support for older Rosetta dependent code.

My mac keeps shutting down by itself

My mac keeps shutting down by itself. Seems to be when I'm trying to edit video on FCPX or when kids are playing a game. Its an older 2009 20" imac 2.66 Ghz Intel core Core 2 Duo running OS X 10.9.4
How can I stop this please? Thanks

These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
For this step, the title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
Each message in the log begins with the date and time when it was entered. Note the timestamps of the BOOT_TIME log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
☞ When posting a log extract, be selective. A few dozen lines are almost always more than enough.
☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Step 2
In the Console window, select
          DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
(not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar.
There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". A shutdown stall report has a name that ends in ".shutdownstall". Select the most recent of each, if any. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot. It's possible that none of these reports exists.
I know the report is long, maybe several hundred lines. Please post all of it anyway.
☞ If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
☞ Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

My G5 Power mac keep shutting down

Hi,
All of a sudden My mac keeps shutting down, I have installed nothing recently no changes nothing for months
and all of a sudden it keeps shutting down.
Check the hard disk using disk utility and it says it appears to be okay
CPUs running at 60 to 62 degrees
please help
John

I believe -122 is a power issue...
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange problems...
See which one your G5 has...

ITunes keeps shutting down when I open it up. The message says iTunes has stopped working. A problem has caused the program to stop working correctly. Windows will close the program and notify you if a solutions is found.

iTunes keeps shutting down when I open it up. The message says iTunes has stopped working. A problem has caused the program to stop working correctly. Windows will close the program and notify you if a solutions is found.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.
If you've already tried something like the above then try opening iTunes in safe mode (press and hold down CTRL+SHIFT as you start iTunes) then going to Edit > Preferences > Store and turning off Show iTunes in the Cloud Purchases. You may find that iTunes opens normally now.

My MAC Pro shuts down when the battery still has 52 minutes life without any warning. Does anyone have this problem? BTW, it is less than one year old.

You must have a MacBookPro, right? MacPro's are big desktop models.
