24" iMac intel--Sleep issues--simple as widgets

Had major sleep issue with brand new new gorgeous 24" intel 2.8 imac. It wouldn't autosleep no matter what I did--reset PRAM, SMU, archive and install, checked console logs, etc. After some common sense thought, I figured it might be a really simple thing. So, I turned off three of the animated widgets (the aquarium, the CPU monitor, and the beach scene). I tried each one individually, and any one of the three had sufficient CPU activity to prevent sleep. After deleting the three of them, everything was fine, and it now sleeps like a baby.

My pleasure--one of the dead giveaways was that my Macbook Pro 15 Core duo had the same apps and files, but she lacked some of the widgets, and it slept perfectly from day one. This is my 5th Mac, and I know that some third party applications are often more damaging than they are positive. Widgets are not necessarily tested for compatibility with the system files of all models.

IMac Automatic Sleep Issues

Hello,
A few months ago I purchased a iMac 20" 2.66Ghz factory default model. The machine has been performing beautifully. Although I've been encountering one major issue. The iMac will manually go into sleep mode, but it will not automatically do so.
So I have tried various different methods to get this guy running properly. So far, I have tried clean reinstalling Leopard (from the restore CD's) twice, resetting the vram, the SMU, I tried different Leopard updates - including 10.5.4, 10.5.5, and 10.5.6. I do not have any third-party accessories plugged into the unit. I disabled Bluetooth since I do not use it, but Airport Extreme is always in use.
The ram, hard drive, and all factory installed hardware is showing up and working properly.
I'm stuck on what I should do. So far, the only solution has been to use a application called "PleaseSleep," which essentially forces the machine to go into sleep mode based on the designated time set in the energy saver preference panel.
I have read many other threads related to this issue here. But I am unable to find a clear solution.
Thanks!

How do you have your Sleep options set in the System Preferences/EnergySaver/Sleep panel?
"the only solution has been to use a application called "PleaseSleep," which essentially forces the machine to go into sleep mode based on the designated time set in the energy saver preference panel." Third party apps that control anything in your System Preferences panel can cause more headaches they they are worth.
If you haven't tried running the Apple Hardware Test, it might be a good thing do. Process of elimination: http://support.apple.com/kb/HT1509
"The ram, hard drive, and all factory installed hardware is showing up and working properly."
Have you actually booted from your restore disk and checked the hard disk for errors? If not..
Follow these instructions to verify the hard disk for errors:
Open Disk Utility, in the Utilities folder in the Applications folder.
Select your disk, and click First Aid.
Click Verify Disk.
If the disk needs repairs, do one of the following:
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the menu bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click Repair Disk. When Disk Utility is finished, from the Menu Bar select Utilities/Startup Disk. Select MacintoshHD 10.5 in the window and click: Restart
If you don’t have a Mac OS X Install disc, restart your computer while holding down the Shift key. As your computer starts up, it performs a disk check similar to the one Disk Utility performs.

Imac Intel - Sleeping display (only imac screen )

I Get a Imac 2008 Alu , And I use it like a media center with a videoprojector ( videoprojector is the second screen) All works well , but As the Imac Screen is very very Bright , I want to Sleep the display of the Imac , but get the Second display On .
the SHIFT + CTRL + EJECT sleeps all display !
For the moment I use Darkadaed Pro to modify the gamma and decrease the brightness of the imac , but it still have a light source from the imac .
Can it be possible to select which display you want to sleep ( maybe in terminal ) or its an hardware limitations ?
Before my Imac i use the macbookpro and with it you can decrease the brightness to a value near 0.
Thanks

Intel-Based iMac never sleeps automatically

I can't remember when this started happening, because I would often leave downloads running overnight, and I set Transmission to keep the computer awake. But now, even on a fresh boot, the computer won't go to sleep by itself.
It sleeps fine if I press command - option - eject or the power button, or even from the menu, but it does not want to go to sleep without help.

Hi sebastian406
First reset the iMac's SMC as described in the article below:
http://support.apple.com/kb/HT1543?viewlocale=en_US
Then if it still won't auto sleep move on to the next article:
http://support.apple.com/kb/HT1776?viewlocale=en_US
As you can see in the article there are lot of things like connected devices HD, iPod, etc. or the sharing services of the Internet and iDisk that can cause auto sleep issue's.

Odd iMac sleep issues

I first noticed the issues a couple of weeks ago - mid-2007 iMac, running SL.
The iMac will sleep fine if I use the command in the apple menu or the power button.
But it won't sleep automatically as suggested in the Energy Saving preference pane. If I select the 'sleep' keyboard combination (option, command, eject), the iMac sleeps but instantly wakes again.
I've tried everything! These problems aren't due to peripherals - it was working fine with the same peripherals connected. Wake for LAN isn't selected, nor is the wake for BT option (and I don't have any BT devices). I've looked in Activity Monitor and Console and can't find any obvious process that might be keeing the Mac awake. I've tried restoring plists from a TM backup, deleting plists, resetting the PRAM and SMC. One of these measures (not sure which one) worked ONCE. But when I went into the energy saving preference pane, it stopped sleeping automatically again.
My main concern is the lack of auto-sleep. I've scoured the forums and no one seems to have this problem together with the mac waking instantly after the sleep keyboard combo. I'm hoping this peculiar combination of probems might shed some light on what's causing them.
Any help would be greatly appreciated.

Can be very hard to impossible to track down auto sleep issues. Just get PleaseSleep.

Sleep Issues with g5 Imac

I have a g5 iMac running OsX Panther. 1.6 Ghz with 256 Ram.
Anyways, the computer randomly and frequently goes to sleep. The hot corners are not set for that, infact in the settings i've set it to never go to sleep. Some days, like in the last hour, the computer will go to sleep, i wake it up, and within a minute, it goes back to sleep. Some days it wont go to sleep at all. The problem seems to be truely random. The only programs running are Entourage, Safari and Adium, sometimes Itunes and Filemaker.
Has anyone heard of a problem like this before? Any tips or trouble shooting ideas?
Thanks.

First read Apple doc.#25801 on sleep settings.
A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours could be the 10.3.9 Combo update (you did'nt say what version you are using). Others reading, download the combo update that applies to you!
Cheers!

Sleep issues with iMac

I have an iMac, first gen, that when I put into sleep mode, it will wake up right away. All software is up to date, running 10.6.8.

Test after each of the following steps:
Step 1
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter ▹ Wake for network access: uncheck. You may need to unlock the preference pane by clicking the lock icon in the lower left corner and entering your administrator password.
Step 2
 ▹ System Preferences ▹ Energy Saver ▹ Schedule… ▹ Start up or wake: uncheck
Step 3
 ▹ System Preferences ▹ Print & Scan ▹ Open Print Queue...
Check all printers for unfinished jobs. Deal with any you find.
Step 4
Disconnect all wired peripherals except keyboard, mouse or trackball, and monitor, if applicable.
Step 5
Launch the Activity Monitor 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.
☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Activity Monitor in the page that opens.
Select All Processes from the menu in the toolbar, if not already selected. Enter “powerd” (without the quotes) in the "Filter" text field. Select the powerd process and click the Quit Process button in the toobar (stop-sign icon.) In the sheet that opens, click Force Quit. You’ll be prompted for your administrator password. The process will be relaunched immediately.
Step 6
Boot in safe mode and log in. The instructions provided by Apple are as follows:
Be sure your Mac is shut down.
Press the power button.
Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
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 boot 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 Mac 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, reboot 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 booting out of safe mode, post again.

Update- I deleted HP via Hp uninstall and also did a search on HD and deleted anything that siad HP. Reinstalled HP prpgram via original CD, then downloaded and installed OS 10.6 drivers and software from HP website then ran Apple software update and it updated 2 files and restarted the computer. The HP photosmart studio still did the same thing running very slow and not responding to clicking on any command. I called HP and they don't have Apple support on Sundays. Not sure if they will ever help me b/c I don't have extended service plan or they want to charge me. Apparently fro do google searches, they have been problems with the software and OS X 6-Snow Leopard. It's funny, I can print but just not use the photosmart software anymore. The problem seams to have worsened after I made a picture DVD using iDVD.- Where does iDVD get installed from? It's not part of iLife. I may uninstall iDVD and reinstall if I know where I got it from and see if that helps. I did run iPhoto yesterday and except for taking a long time to import my photos (hours for 1,600 picutres), it seems to run fine, so I can use that as long as I can use the printer to print and scan. I uninstalled HP again and was going to try reinstalling and only doing the Apple software update after and see if that chances anything. I will try calling HP after I have the software back on my computer. If I do decide to buy a new printer=- any suggestions?
Thanks

What is the best time to set for my iMac intel to get to sleep?

what is the best time to set for my iMac intel to get to sleep? the default is 10 minutes, i am changing it to 1 houirs but i put the sleep time for my monitod 10 minutes. is it decent?

Not so sure of that "just plain logic." Allowing sleep too often will cause wear on the drive -- excessive spin up and spin down. Temperature permitting, a drive will last longer if just left running.
For other hardware, a lot will have to do with the internal temps. When it's quite hot here, I allow the computer to sleep more often. But otherwise, it's a bit of this and a bit of that. I wouldn't personally recommend running 24/7, although I know of several here who claim they do, with no apparent adverse effects over many years.

Why will my iMac Intel Lion no longer go to "sleep" using the Apple drop down menu?

How can I get my iMac (Intel / Lion 10.7.4) to go to "sleep" using the Apple drop down menu. I have never had a problem until recently.

Some process is running that is preventing sleep mode,
Zap the PRAM and see if that changes things.

Hi, please, anybody knows how many coolers has an iMac 27 Intel core i5? The widget iStatpro shows 3. I changed my HD (the previous one of 1TB crashed) and after that the HDD cooler is constantly working at 4.600 rpm. Anybody is facing this problem?

Did you replace the HD yourself? If so what HD did you use?
You should be aware that the symptom you describe is likely to be because you've used an incompatible HD. The current Macs have the temperature sensor actually in the HD package, with a modified cable to connect to the logic board.
If the sensor is not in circuit, the fans will run full tilt all the time.
Also, if it was under warranty, I think you'll find you've just voided it.

I am puzzled by iMac(Intel ?). I am running an iMac 24 and use Mac:Office 2008. After having downloaded my Os X LION upgrade, I am suddenly unable to SAVE (and thus alter) my Excel quotations. This is a major issue for a salesman. Can anybody help me

I am puzzled by the meaning of iMac (Intel) as I use an iMac 2 period. I am running Mac : Office 2004 and do all my quotations in Excel. After upgrading to OS X LION, I am suddenly unable to SAVE my spreadsheets. As a salesman whose quotations need frequent updating, my situation is perilous to say the least. Can anyone help me ?

Office for Mac 2004 is NOT compatible with Lion. It must be upgraded to Office for Mac 2008 or 2011, once you have upgraded the files will be accessable. Office for Mac 2004 is written for old PPC (Power PC) based machines. Beginning with Lion support for PPC based apps has been dropped.

White iMac Intel with 10.4.1 takes 40 seconds to sleep after clicking on it

My dad's machine (after a restart) will take under 3 seconds to go to sleep after the command...but after checking email and unloading camera or some surfing- for some reason it takes almost 40 seconds.
I reduced spotlight's things to check, removed all superfluous fonts, used Activity Monitor to see if anything weird was running, removed Google Desktop....
Nothing helps...not to mention it just generally runs slow. It has plenty of RAM. I just don't get it. I have followed all of the "Tips to optimize speed on the Mac" and no luck.
Any ideas?

See if any of these provide pointers.

IMac G5 pre-Intel sleep problem

I cannot put my iMac to sleep manually by using the toolbar. Have tried reinstalling OSX, and anything I can think of. Any help?

It could be the power supply, but it also could be a failing logic board or hard drive. If it were the power supply, your machine would shut off when it got too hot. If you can boot from your install disc, use Disk Utility to check your machine out:
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
You can also run Apple Hardware Test which should be on one of your install discs.
Once you done this, please let us know how things went,
