IMac turns off when put to sleep

I have an iMac without iSight, 1.6GHz. Whenever I put the computer to sleep it just turns off instead of going to sleep. I dont know what I can do to fix this but it is really annoying because I dont like waiting for the computer to turn on when I want to use it, but I hate leaving it running all day, what do I do?

I had the same problem and the problem was with the power supply, supply replaced, problem was fixed. This "repair extension" was announced a year ago, but buried on the Apple websites. I didn't know about myself until I got help on the board. I am surprised that the Consumer Product Safety Board hasn't forced Apple to make this a recall to fix a clearly defective power supply. The people at the AppleStore (AppleCare techs were no help by the way) knew exactly what the problem was as they had fixed many, many time before. Apple should do the right thing by its consumers and issue a recall on computers with these power supply problems.

Imac turns off when going to sleep

Hi,
My imac shutdowns and I need to manually turn it back on - it has happened a few times now when I put my computer to sleep. Anything I can do to stop this? Should I be contacting Apple? Is this a big issue? Thanks Bethany

If the computer successfully goes to sleep/wake, it will post lines in console like this:

Nov 28 18:56:53 computername kernel[0]: System Wake
Do you get any lines like these around the time it happens?
Also, resetting the SMC might be a good thing to try:

Airport Card turned off when resuming from sleep - New since 10.6.6

I use safe sleep regularly, as I use my laptop at both work and home. Ever since the update to 10.6.6 though, I have had to manually turn my Airport connection back on after resuming from sleep.
Previously, although it was unreliable about connecting to a preferred network (an unrelated, but equally frustrating issue*) at least it would remain on. Now I've had to add the icon to my Menu bar just so I don't have to dig into System Preferences every single time I reawaken my laptop.
Does anyone know why this is happening, and if there is anything I can do to prevent it? I apologize if this has been asked before, but when I searched I was unable to find anything.
*This issue is unrelated and not the focus of my post, but if you happen to know about it I would absolutely appreciate your input.
When resuming from sleep, despite being between 5-20 feet from my preferred router I will often receive a dialog asking me to select from a list of SSIDs and enter a password even though that information is already saved. Then, once I complete this information Airport doesn't actually connect and the only way to resolve the issue is to turn Airport off and then back on. After this, it will automatically connect with no problems and remain connected until I put the computer into Sleep mode again.

Maybe check in your keychain and verify the password saved is correct for your wireless router?
Do you broadcast the network name?
Could you describe "unreliable about connecting to a preferred network"?
Is "use secure virtual memory" checked in the Security preference pane? If so try unchecking that maybe? If it's a hibernation issue sometimes that could cause weirdness.

IMac turns-off when you adjust the screen

Brand new iMac simply turns-off without warning when you adjust the screen or connect to the usb port.
How do you prevent this from happening??

It sounds like you may not have the power cord pushed in tightly enough
to the back of the screen port. Push it in really really tightly, OK?

IPod Touch turns off when shaken during sleep mode & other problems

I noticed a problem with my iPod Touch around a month after I bought and I thought it was normal for the iPod Touch to act that way but it seemed rather getting into my nerves. I will try to describe the situation the best way I possibly could so please bear with me.
First, I have a problem with my iPod when it's at sleep mode. When I press the home button too look at the time/date for example and then I shake it or move it before it blacks out and goes back to sleep mode again, it hangs up and I have to press the power & home button to turn it off. It happened all the time and it gets really annoying because when friends borrow it, it dies.
The same thing happens when I play a song and then I don't put it to sleep mode. When I shake it, it hangs up.
Second, when I use my iPod at night before sleeping to listen to music and the like, the moment I wake up, the battery is totally drained. I am DEFINITELY sure that no song was playing at that time and it was even fully charged. Last night I decided to monitor my iPod on a regular basis to see at what point in time the battery starts to diminish. I fell asleep but when I woke up at around 10 to check my iPod, the screen is black and yet it's on because the screen is glowing. I restarted it and when it went on again, the applications are all disarranged.
Third, there are duplicate songs in my iPod although when I check in my iTunes to delete the songs, it only appears as a single song but it is in duplicate in my iPod.
What do I do? Thanks!

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.

IMac Turns Off when start using DVD Drive

I first noted this problem when I try to install windows and thought that was a boot camp problem: every time it start the instalation then shutdown (no warning, it seens like it was unplugged). I tried Vista DVD and Windows XP CD (both original medias already tested in a PC).
Then a noted that the problem occours when the iMac try to use the DVD drive. It's not related with the media, sometimes it happens and sometimes it does not with different CDs/DVDs and softwares (iDVD, Finder).
Any help?
P.S. Sorry for my english.

oooohh well that fixed up my DVD burning issue
UDMA 2 =~ 33 m/b sec?
16x DVD = ~ 25mb sec?
If the above numbers are correct then that should be fine as a band aid fix for my DVD burning issues
Thanks a load!
Your sir are a gentleman!
Also since my last post I found that I supposedly wasn't running the latest BIOS...
I flashed from 1.6 to 1.11 which is listed as the newest here:
http://global.msi.com.tw/index.php?func=downloaddetail&type=bios&maincat_no=1&prod_no=252
But I installed MSI Live Update 3 (I've never used it before) and it said there was a "1.B" BIOS... so I let it re-flash to that one...
I'll try out my USB printer again once this DVD finishes burning

Wifi automatically turned off when phone sleeps in iOS 5.1.1?

Before, I used iOS 5.0.1 and wifi would keep turned on when the phone sleeps if I turn off data. This way I could always receive instant notifications. But then I sold the verizon phone and bought a used FU one, installed with iOS 5.1.1. Now wifi is automatically turned off when phone the sleeps, even when data is off. Is this how it works? Because I want to use wifi, even when the phone is off. Thanks.

I have had and iphone 4 for the last couple of years with all the different IOS upgrades and never experienced such a thing!? I do not have a cell data plan (I even have it switched of in settings) so I rely on wifi and, even when the phone was in standby, the wifi was constantly on! and I received e-mails and skype calls as they arrived, So wifi was certainly ON!
However, since the last upgrade to IOS 6.0 the wifi is indeed being turned off when the phone goes to sleep mode, which is very annoying!
Any fix/workaround?
Thanks

PowerMac G4 switches off when set to sleep

My venerable PowerMac G4 works just fine. However since a few weeks it switches itself off when put to sleep. The switch-off is a crash, like the power plug has been unplugged. An immediate restart doesn't work, the light just goes on for a second or two, afterwards the whole power vanishes again. After a few minutes the Mac can be normally restarted.
When left of the Mac works perfectly and doesn't crash at all.
Sounds to me like a certain power which is to be supplied by the internal power suplly just during sleep-mode is gone. Any ideas?
Thanks

hi,
thanks for your suggestions. I trashed the com.apple.powermanagement.plist file but there was no autowake file. The behaviour remained the same. I then reset the PMU as you suggested - still no change.
In the meantime I got another problem: the mouse is behaving erratically, the pointer is moving in jumps or not at all. The mouse shows the same behaviour when plugged in to my PowerBook - it must be faulty. I have just ordered a new Mighty Mouse to rule out any issue deriving from a broken mouse. I will also change the Lithium Battery on the motherboard even given the voltage is at 3,64 V, which should be sufficient.
Do you have any further suggestions?
Thanks in advance!
hi wolfman62--
i would try a couple of things. first, go to
/library/preferences and trash a couple of files in
the folder called systemconfiguration --
com.apple.powermanagement.plist and
com.apple.autowake.plist. then restart the
computer. test to see if there is any change. if
not, try resetting the pmu. to do this, shut off
all power to the computer and disconnect any
peripherals. then remove the power cord from where
it goes into the back of the machine into the power
supply. then remove the side panel and plastic air
deflector if your model has one. then look on the
bottom left corner of the logic board under the
bottom set of ram banks. there is a little square
with a button on it. (you might have to remove a
fan in order to find it.) ground yourself by
touching some metal and then letting go, and then
press the button on the logic board counting one one
thousand, and then release it. do not press it
twice as it can blow the chip. then put everything
back together and see if there is any difference.
let me know if either of those things makes any
difference. [ 8 ) ]

In fact, do 3 in a row, takes a bit of time.

(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.

Why iMac shuts off when in sleep mode? Using latest System (Yosemite)

Can anyone tell me why my iMac 27", running on the latest system (Yosemite), all of a sudden started shutting off when put in the sleep mode?

Try resetting the SMC.
Additionally, look at the log files around the time the system shut down.
You might also take it in for testing/diagnosis.

My iPhone 4S was turned off when the battery got empty, and when I put it on the charger it didn't charge at all. I tried restarting it (on/off home button for 10 sec) nothing happened except it kept giving me the "charge battery" on its screen.

Hi! My iPhone 4S was turned off when the battery got empty, and when I put it on the charger it didn't charge at all. I tried restarting it (on/off home button for 10 sec) nothing happened except it kept giving me the "charge battery" on its screen. I tried with different chargers, still dead! What's weirder is that my sister who has iPhone 4 experienced the same today! No we don't live in the same house!! Does anyone have the same problem?
Please apple support do you people have a convincing answer for us? Is there a solution? My phone is only 2 years old and was (2 hours ago), in top condition!!
Please help....

On belhalf of my fellow volunteers, the answer is, "We'll try our best."
My advice is to try not to treat this like it is a paid service provided by compensated professionals. Ask nicely and one of the nice folks here might take some time out of their weekend to offer advice.

IPhone turns off when in sleep mode

Hi my phone turns off after being in sleep/lock mode after a few minutes. to turn back on i have to hold the home and power buttons for a few seconds.
When the phone is charging it does NOT turn of in sleep mode.
My Info: iphone 2g..Fw 2.1
I read a few post on here and other forum sites that say it may be a hardware issue or battery issue....If your having this problem please reply to this post to let it be known if there is a hardware problem or just isolated incidents thanks

Hey SurgeCentral,
Are you using any 3rd-party accessories with the iPhone?
Try syncing and backing up the data on the iPhone, then restore it and set it up as a new phone.

Why does my iphone keep turning off when i put my pass code in

why does my iphone keep turning off when i put my pass code in

Hi ManiPictures,
If your iPhone shuts down unexpectedly during use, I would suggest that you troubleshoot using the steps in this article -
If your iOS device restarts, displays the Apple logo, or powers off while you're using it - Apple Support
As your iPhone's operating system is already up to date with iOS 8.1.1, follow the last instruction -
If you still see this issue after updating, contact Apple Support.
Thanks for using Apple Support Communities.
Best,
