IMAC G5 shutsdown while in sleep

The computer shutdown overnight on its own. The back was warm and I could not restart the machine - no chime or screen response. The only thing I saw was an LED on a usb device turned on briefly. I unplugged the power cord waited a while and then got a chime, and the usb led but nothing more. After about 30 minutes it was quite a bit cooler and the machine booted and ran OK. Sometime later in the day it went to sleep and the fans started whining and it shutdown. I checked the console as recommended elsewhere and got a reason for the shutdown as -110. (I assume that indicates a power supply, which was replaced two years ago) The next day I disabled the shutdown mode and it remained on all night. Is there a way to be sure it's a power supply before buying one and finding out it's the logic board? The machine is 5 years old and has been trouble prone. Thanks.

110 is the code for thermal problems, and it's either the power supply or defective caps. You can open the machine up and inspect the caps and you can also run DiskWarrior or TechToolPro if you have access to either.
You can also check the [LEDs|http://support.apple.com/kb/HT2831] to see what they indicate.

IMac receiving connectivity while in sleep?

I have a 20" iMac and I also have an Xbox 360. I know how to connect my Xbox to my iMac and play online via the Mac's airport. But my problem is I want to put my iMac in sleep and still be able to play online. So basically I'm wondering if you can keep the wifi on while the iMac is in sleep mode. Because currently when I put the iMac in sleep the connection turns off.

If you put the iMac completely to sleep the iMac's internet connection does not operate.
You could simply put the screen to sleep and keep the iMac operating.
The best solution is not to use your iMac as a wireless router. Instead get an inexpensive wireless router. This has many advantages including the fact that your iMac can sleep or be turned off without affecting your Xbox's connection.

What keeps making the cyclical noise while in sleep. Sounds like iMac is loading a graphic or different screen.

What keeps making the cyclical noise while in sleep? Sounds like iMac is loading a graphic or different screen. Does it periodically while in sleep mode. How do I correct this? Just started doing it in the last few months.

I finally figured out how to fix this. First I reviewed "Mac OS X: Why your Mac might not sleep of stay in sleep mode." I noted the bullet: "Do you have any other external USB or Firewire devices connected?" I have an CP685AVR for a UPS for my Mac. I replaced the battery a few months ago. I also hooked up Apple's 'Energy Saver' power management software to the CP685AVR using the USB connection. I disconnected it, and that solved the problem. I still have the UPS and battery back-up; I just can't "monitor" the battery. What's to monitor? It always said the battery was 100% charged even right up to the time the previous battery failed. Thanks for listening, uh... reading.

IMac turns off while sleeping

My iMac sometimes turns off during sleep mode, I did call apple care and went through utilities and the tech support said that issue should be resolved, but it happen again today. Has anyone else had the same issues? Is this also the start of some bigger issues down the line?
Thanks,
BC

HI BC,
Check System Preferences/Energy Saver. Click the Schedule button bottom right in that pane and make sure it's not set to turn off at a certain time.
According to this article, http://support.apple.com/kb/HT1237 Make sure your software is up to date.

Time Machine STILL backs up while in sleep

Time Machine STILL backs up my drive to an external drive while in sleep, despite many Apple KB articles to the contrary and 2 conversations with Geniuses saying it shouldn't either. Why?
I have turned of "wake for network access" under energy settings as recommended, but that didn't help either.
But if I open the external drive's backup folder there's a new folder for every hour in the last 24 hours, even if the computer had been asleep the whole time.
IMac is now on Mountain Lion, but it did the same under Lion as well.
Any help or suggestions would be appreciated, thanks.

Yeap that all makes sense now.
Do you only have the current backup showing in the TM display?? Won't it fill in the rest?
Over wireless are you waiting for the indexing to finish.. ??
Previous backup may not show for a couple of hours.
Long short of it.. Mavericks version of TM is a pain.
Sometimes it is easier to completely ignore the TM backup and do the restore manually.
I have posted the details here. See if this helps.

Imac g5 crashes while asleep; can't boot from cd/dvd

My imac g5 crashes while asleep. Both the display and hard drive are set to sleep.
In trying to fix this problem with Apple tech support, I've discovered I can't boot from the cd/dvd. When I hold down the letter c while restarting, the disk ejects. I've tried three different disks: the install dvd, a Norton Systemworks bootable cd, and the bootable cd from AppleCare. All are ejected.
Have I got some hardware problem(s)?

Since we couldn't fix this over the phone, it's now at the Apple Store being fixed. They've replaced the power supply and, after I called again and made sure they tested it by having it sleep for a couple of hours (they couldn't wake it up after that), they're replacing the logic board.
I've been disappointed by the amount of hardware that's had to be replaced on this computer. I also had to replace the mid-plane assembly about six months after buying it in Sept. 2004.

When I click sleep, Imac turns off not just sleep

When I click sleep, Imac turns off not just sleep. Any fix?

Hi Hank,
Some things to try...
Have you done a PRAM reset, CMD+Option+p+r...
http://support.apple.com/kb/ht1379
In fact, do 3 in a row, takes a bit of time.
Intel-based Macs: Resetting the System Management Controller (SMC)...
http://support.apple.com/kb/HT3964
(SMC reset= Shut down, disconnect power cord for 10 seconds, reconnect power cord, wait 5 more seconds, turn computer back on)
but it is slightly different: (PMU REST = Shut computer down, disconnect power cord for 10+ seconds, reconnect power cord WHILE SIMULTANEOOUSLY PRESSING POWER BUTTON, let off power button for a few seconds, then press power button again to restart the mac mini.)
Can also be caused by USB or Firewire devices.

IMac turns off instead of sleeping

This only recently started occurring, and I cannot correlate it with anything that I might have done.
When I tell my iMac G5 to go to sleep - be it via shortcut, menu, power button, anything - it turns off instead of sleeping. It does not shut down properly, but simply turns off suddenly and completely. Upon rebooting, everything seems to be functioning well.
Did all the usual reboot, fix permissions, and so forth, to no avail. Apple hardware test reports no problems, although it took over an hour to run an extended test.
Any help would be appreciated.

You haven't done anything, it's a power supply problem or a capacitor problem and you should take it in and have it seen to before it gets any worse. Make sure you have a backup of all your data before you take it in. If it's not an iSight, you can open the back and check the caps to see if they are swollen or leaking. While you're about it, vacuum the fans and the vent slots to see if excessive dust buildup is the problem.

MacBook Air 2013 battery drains quickly while in sleep mode

I just purchased a 13" mid-2013 MacBook Air this week, and so far everything is working well - a remarkable improvement over my 2007 MacBook! But, I've noticed that the battery seems to drain very quickly while in sleep mode. For example, it drained 10% over five hours. I've turned off bluetooth and made sure that the PowerNap option is not selected under Energy Saver preferences. And the battery health/capacity seems to be good. Are there other things that I should turn off/check out? Has anyone else experienced this? Is this even abnormal for the battery to drain at this rate while in sleep mode? Thank you!!

You can return a new Mac within 14 days of purchase.
A new Mac is in warranty for 1 year from the date of purchase.
A new Mac comes with 90 days of free tech support from AppleCare.

Imac no longer going to sleeping after update on July 8, 2014

just did the latest update on this week to 10.9.4 Build 13E28 on my iMac 2.5GHz Intel Core i5 and now my iMac well not go to sleep on its own.
have already reset SMC
pulled the com.apple.PowerManagement.plist
reset PRAM
reset power setting in system Preference panel
anyone else having this issue? my system was working perfect before this update..
really don't want to wipe and rebuild my system at this point.

Test after each of the following steps that you haven’t already tried:
Step 1
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 and test. If you use a wired keyboard and/or mouse, use different ones. You must rule out the wired keyboard and mouse as possible causes of the problem.
Step 6
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 turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup 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 start 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 7
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 8
If sleep is still working after you’ve launched all the usual applications, restart 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 restarting out of safe mode, post again.

Crashes/reboots/restarts while on sleep

This thread is exclusive to people who have spontaneous crashes/reboots/restarts while their Mac is in sleep. (this is usually connected to having a USB external hard drive plugged in the computer while on sleep)
In simple words, you are experiencing this problem:

ANSWER
PS
Please forgive any mistakes in this text, unfortunately english is not my native language.
<Email Edited by Host>

1. Which Mac do you have? (If you have this issue with multiple machines, list them here)
Macbook Pro Retina late 2013. 512Gb SSD, 16Gb RAM, 2.3Ghz core i7 with discrete GPU.
2. When did the problem start? If you had Mountain Lion installed on this machine, did the problem start when you updated to Mavericks?
I purchased a 4TB WD MyBook and split it into two partitions with one of them being used for Time Machine. After that, I received the reboots during sleep.
The computer came preinstalled with Mavericks.
3. Did you have your Mac replaced from Apple because of this issue? If yes, does the new machine still have the problem?
No, I haven't had it replaced. I contacted Apple 4 days after the problem started. I had turned off PowerNap, but still had the problem. Apples asked me to disable Wake for Wi-Fi Network Access, and since doing that the problem has disappeared.
4. Does your machine crash/reboot while on sleep only if you have an external hard drive connected?
Yes (before I turned off PowerNap and Wake for Wi-Fi)
5. Does your machine crash/reboot even if you uncheck "Enable Power Nap" in Preferences, Energy Saver? (before answering this, check that you have updated OS X to 10.9.1 and that you have unchecked Power Nap in both the Battery and Power Adapter tabs in Energy Saver)
I have to have both PowerNap and Wake for WiFi disabled. If either is checked, the computer reboots. I've confirmed this with both 10.9 and 10.9.1.
OPTIONAL QUESTIONS
6. Do you have an external hard drive connected via USB? If yes, write the manufacturer name and model name of the drive. (example: Western Digital My Book)
Yes. Western Digital My Book 4TB. Split into 2 partitions.
7. Do you have a network connected drive? (like Time Capsule or an external hard drive connected to an AirPort Extreme, or a NAS)
No.
8. Do you have Time Machine Enabled?
Yes.
9. Do you have Crashplan installed?
No.
10. How much time does it usually take for the first crash/reboot to happen, after you put the computer on sleep?
4 hours. Checking the console log, my computer wakes itself at 2 hours for Time Machine (even if PowerNap is turned off, which is why Wake for Wi-Fi needed to be disabled, even the drive wasn't connected over the network, which really makes no sense) and then on the second wake, it has the Sleep Wake failure. Then it proceeds to reboot every 2 hours after when it wakes for Time Machine.
11. If you have a late 2013 MacBook Pro Retina, do you have discrete graphics in it? (In other words: do you have an NVIDIA GPU? If you don't know this, go into the menu bar, click the apple icon, click About This Mac, Click More Info, in Graphics you should find written “NVIDIA GeForce”.)
Yes.

HP Officejet Pro 8625 - Will not acknowledge incoming fax while in sleep mode

HP Officejet Pro 8625 - Will not acknowledge incoming fax while in sleep mode. The sender receives an error "no answer".
When I call the fax number, if I touch the screen it will wake up immediately to receive the fax.
Printing from the computer while in sleep mode works fine.
Please advise. Im missing important faxes and can only set sleep mode to a maximum of 15 mins, so I have an alarm set to touch my machine every 15 mins. sigh...
Thank you,

Hi Willia,
Welcome to the HP Support Forums! I see when your HP Officejet Pro 8625 enters sleep mode, you are unable to receive any incoming faxes. The senders will receive a 'no answer' error. I understand your printer will wake up from sleep mode if you send a print job.
First let's go ahead and make sure the OJ 8625 is plugged directly into a wall outlet, using a power bar or surge protector can cause the printer to lose basic functionality over time. To get a better understanding take a look here: Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector
Now, I would like you to update your printers Firmware, click on the link below and follow the on screen instructions:
HP Officejet Pro 8620/8625 Firmware Update
Are you now able to receive incoming faxes when the OJ 8625 is in sleep mode? If not, I would like you to contact our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

IMac fails to wake from sleep

This is an ongoing problem that has been addressed by Apple Care and a Mac Shop. The hard drive, Logic Board, Ram, and Super Drive have all been replaced.
The Console gives a repeating message of:
8/26/08 8:43:07 AM com.apple.launchd[1] (com.apple.nis.ypbind) Throttling respawn: Will start in 10 seconds
