ImacG5 powering down

Hello
Looking for some help. New computer user with ImacG5 that is powering down after about 15 minutes of non-use. At first the computer was making "whirring" noises and was a bit difficult to turn back off, but that no longer seems to be an issue.
The computer is just quitting on me... is there some way this might possibly be diagnosed or better yet, resolved, without a 200 mile trip to the Apple Service Center?
Thank you for reading

Hi Momfisher,
First, take a look into the Apple Repair Program: http://www.apple.com/support/imac/repairextensionprogram/ - you machine exhibits some of the same issues addressed in the program. Your machine may or may not be on the list, if it is, call Apple...

Since I updated my 4S iphone to the latest iOS7 version, I can no longer close any of my apps. As a result, all my apps remain open on my phone. Even powering down and restarting does not solve the problem. Specifically, the icons don't wiggle anymore.

Since I updated my 4S iphone to the latest iOS7 version, I can no longer close any of my apps. As a result, all my apps remain open on my phone. Even powering down and restarting does not solve the problem. Specifically, when I double-click the start button, my open app icons display. But when I hold my finger on an icon, the apps do not wiggle and display an "x" to close. Any advice... thanks?!

Double tap the Home button, then swop upwards on the App Preview (not the App Icon). Tap the Home button again when done to return to normal screen.

HP Officejet Pro 8500A fails to print until powered down and restarted.

This problem has arisen after about a year of giving good service. Although it says "Now Printing," it does not print until powered down or disconnected and restarted or reconnected for each print job. I will be most grateful for any suggestions for fixing this.

Hi @jmuravchik
Do you have the printer connected directly to a wall outlet or is it in a surge protector or power bar? Even if you have been using a surge protector/power bar all this time and you feel it is not the cause, please connect it to a wall outlet just so we can eliminate the power source as the root cause.

I accidentally powered down my notebook without ejecting my IPod Nano. Now my computer starts up with a black screen with "Press <Esc> to change boot order Press <F10> to enter setup but will not respond if I press Esc or F10. Need help!!! Thanks.

There could be bigger issues, I've unplugged my iPod countless times without disconnecting (and on several different models etc..) and have never had problems .

Hold the HOME and SLEEP buttons at the same time until an Apple logo appears. If it hasn't appeared after 30 seconds your phone is probably broken. If something other than an Apple logo appears see: http://support.apple.com/kb/HT1808.

I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.
Reset SMC no change

Run the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

Time and date settings change when phone is powered down (not shut off)..

I recently installed the iOS 8 update and immediately noticed that the time and date settings would change when I powered down my iPhone. I did not turn off my phone, only clicked the button to power down or save power. I have tried all the fixes, suggestions, etc., but I am still having issues. In the power down state, I am able to receive phone calls or texts but when I go into my phone, the time and date will be off. It stops from the moment I click the button to power down the phone. Please don't get this confused with turning off the phone completely. This happens when I click the button for power down or power save, however it is described.
So, how do I fix it? Is the app/software for the clock the problem? Is the battery distribution the problem? For some reason, in power down mode, the clock is not receiving constant power in order to keep accurate time. It stops the moment I click the button. Any suggestions? fixes, etc. I could try. Apple support techs were absolutely no help what-so-ever.

This sounds exactly like what is going on with my phone, http://www.idownloadblog.com/2012/10/19/iphone-5-date-time-glitch/

Iphone 5 has started powering down after upgrade to 7.02, help please.

My iPhone 5 started powering down after the 7.02 upgrade I did almost a week ago (3 times). I realize now that it starts after I see a message notification on the home screen and click on the slider to enter my passcode and reply to the message.
I never get the chance to enter my passcode and the phone turns itself off. The only way I can bring it back is to connect it to my Mac and launch iTunes. Then it reboots itself and behaves normally for 2 days.
Any ideas are appreciated.
Thanks.

MacBook Air crashes/powers down each time it's turned on.

I replaced OS 10.6.8 on my MacBook Air with Lion 10.7 when Lion became available last week.
Last night I noticed some odd behavior -- extremely slow "genii" minimization of screens, duplications of key strokes, and other anomalies.
Then today, each time I tried to boot up, as soon as the wheel stopped spinning and the desktop became visible:
Several windows automatically displayed -- windows I was working on when I shutdown earlier.
The dialogue box appeared with buttons for | Restart | Sleep | Cancel | Shutdown |
Almost immediately, the power cut off and the screen went dark.
"Reopen windows when logging back in" was checked, so I unchecked it. As a result, the Air now powers down without displaying windows or the dialogue box. It goes black almost as soon as the Apple logo and login wheel disappear. (I'm connected to the Power Adapter, so there's no problem about power.)
I tried several remedies that have worked in the past with OS 10.6+, but they're not working now --
Opening in Safe Mode: the system powered down while I was logging in.
Using Command-R to invoke Disk Utility: The system crashed before I could start Disk Utility.
Resetting my Power Management using the Shift-Control-Option + Power. The air powered down as soon as I turned it on.
Finally, I tried reinstalling Snow Leopard using the Install stick that came with the Air, but the system died before I could initiate a new install. What's going on?
First clue: I tried the fix-errors command, fsck, in single-user mode. It logged into command line fine, bu tbefore I could invoke /sbin/ fsck -fy as usual, a line appeared
: / root# AppleMCP89TMSpowerGatingdown(0)done
and the system died. Did something actually "power-gate down"? What's that mean? (MCP89 is an Nvidia video chip.)
Second clue: When I disconnected the Air's Power Adapter because of a lightning storm outside, the Air rebooted and then died, rebooted and died, etc. (I'm typing these comments on my Pro, of course.) It only stopped when I shut the lid.
Thanks very much for your knowledge, expertise, and suggestions for how to restore my Air or if it's a hardware problem, how bad it might be.

I experienced the same. Then I reinstalled OSX Tiger, put in my Snow Leopard Disc and restored my system from Time Machine. But OS X Lion constantly makes my system crash, so after the last crash (twice a week it did) I reinstalled Snow Leopard and restored what I needed to use from my Time Machine backup manually. (including finding hidden files for my mails, adress book, calendar etc).
I look forward to Apple telling us whether OS X Lion can run on EVERY Mac with an Intel processor from 1.83 Core 2 Duo. I have 2 Gb RAM and everything worked really nice and fine until Lion crashed. And the problem seemed that it has also corrupted my backups in Time Machine when Lion tossed round my files.

I just upgraded to Lion and I have not been able to successfully complete a restart. I go to apple menu, restart. The computer powers down no problem and starts but it does not open the desk top. It remains a grey screen with the spinning icon. Any help?

I have just upgraded to Lion 10.8.2. I have not been able to complete a restart. I go to the apple menu, click on restart.The computer powers down and restarts but never opens the desk top. The screen remain grey and a graphic just spins. I have left this happen for as much as 15 minutes without it openning the desk top. When I power down the computer with the power button and start again with the power button. It starts no problem.

Hi Anythony ...
v10.8..2? Most reccent version of Lion is v10.7.4.
Use Lion Recovery to repair the startup disk if necessary, or reinstall the Mac OS X.

Bluetooth comes on but immediately connects to a powered-down device -- doesn't connect when the device is turned back on.

On my Macbook Pro, whenever I turn Bluetooth on, it immediately connects to a powered-down device. If I click "Disconnect", nothing happens.
When I turn the device back on, I am unable to re-pair with the actual device.
This image shows Bluetooth connecting to the powered-down device (and, again, clicking "Disconnect" does nothing):

I'm also seeing the following issues in Console:

Powering down external HDs on an iMac when shut down

Hi to all, hope you can help .....
I recently added two external WD Studio HDs to my iMac connected as a RAID1 array. This was done using the Mac disc utility and without any reference to the pre installed WD software. I also have a separate Studio HD as my Time Machine and since all 3 have a Firewire connection I daisy chained the cable to all 3 devices (the iMac only has 1 Firewire port) since I thought this would be the fastest option. All 3 HDs appear to function correctly, except when I power my system down the drives remain awake.
Before I added the 2 in RAID array the original Time Machine HD did power down automatically when the Mac was turned off, so for some reason the system doesn't seem to want to cope with 3 HDs.
I've checked in system preferences/energy saving and the box for powering down HDs when possible is ticked.
Any ideas / solutions greatfully received, Cheers !!

Hi Roy,
I'd stick with Firewire. It's faster and I have always considered it more reliable. (It takes a technical discussion to explain why.)
There is no assurance that using USB will make your external drives power down. Again, I want to emphasize that not all drives will power down automatically when you shut down your Mac. Some drives do, some never do, and some have a 3-way switch that allows you to select the power-down behavior. And there may be something about your 2-drive software controlled RAID setup that affects things here.
The energy saver preference item for powering down drives whenever possible applies, I believe, only when the Mac is turned on and idle. (I do not believe it controls powering down external drives when you shut down your Mac.)
Unmounting the drive is as simple as what you wrote - eject it in the Finder. Alternatively, if you have the drive icons on your desktop, you can drag them to the trash to unmount the drive(s). Keep in mind that when you shut down your Mac, it automatically umounts the drives itself anyway.
External drives will automatically remount next time you start your Mac (unless the drive is powered off). If you unmount a drive and then decide you need to remount it while your Mac is still running, you can use Disk Utility. Open Disk Utility, select the drive you want to mount and then click the Mount button.

Mac mini powers down suddenly

My Mac mini often powers off suddenly.
The log shows the following:
configd[15] Sleep: Early Failure - AC
com.apple.message.domain: com.apple.powermanagement.sleep
com.apple.message.signature: Early Failure
com.apple.message.result: Failure
com.apple.message.uuid: E309A210-537E-4DED-BCCF-F1773F1D938A
What could be the possible cause of this?

Changing the sleep mode did not help, it powered down very quickly after that.
I did get the following error:
kernel Previous Shutdown Cause: 3
and after searching for this error code, I reset the SMC. Now waiting and watching....

IMac 27'' keeps powering down for no reason

After about 2 hrs of editing sometimes my iMac 27'' keeps powering down for no reason and then rebooting.

If you have more than one user account, these instructions must be carried out as an 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
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful.
