Put iMac to Sleep, Warm in the AM

Before I go to bed each night, I manually put my iMac to Sleep from the Apple menu. Within a few seconds it shuts down and makes no noise (no fans).
Most mornings however, when I awake, I can hear the fans spinning (primarily the hard disk fan using Activity Monitor), and the top of the computer is warm. When these fans come on I cannot tell, but I'm pretty sure the computer doesn't light/wake up, show the desktop on both monitors, and then go back to screen saving mode and then eventually the screens go dark but the fans still run and the computer stays warm (e.g. not sleeping, just the displays are black).
How do I put the computer to sleep at night, so NOTHING runs (no fans) and the computer is cold in the morning?
Thanks.

Nothings happening, tried the mouse, tried the keyboard, nothing. I followed the instructions for resetting the SMC and the only thing I get is the light sound I describbed in my earlier message. The more i listen I don't think it's the cd drive, I feel like that would be a little louder than the sound I hear. What I'm hearing sounds like a light spinning sound almost like the hard drive when yo click the keyboard to wake it up, except it keeps doing it over and over again until I unplug the mac. When I plug it back in, it will not make the sound until I press the power button on the back.

Put imac to Sleep or Shut Down

What's up guys
I'm just wondering, I use Logic pro
a lot and I would like have quick
access when I have a creative urge.
How often should I shut down my imac
as apposed to putting it to sleep?

Several schools of thought:
1) never shut it off (but it's OK to let the display sleep, i.e., go to screen saver, but never let the computer or the hard drives go to sleep)
2) turn it on and off as needed
3) put the computer to sleep (including display and hard drives) when not being used
Considerations:
1) "always on" --- if having immediate access to your computer to get down creative ideas ASAP is important then there should be no other factors to consider.
2) "on/off as needed" -- the exact opposite of #1
3) "sleep" -- a happy medium? It depends... Waking a computer from sleep still means that you have to wait a while before you can start to record. You should experiment with your system to see how successfully it wakes up after being put to sleep before committing to this practice. Sometimes a system won't wake up from sleep and you'll have to re-boot anyway.

Firewire drives won't spin down when I put iMac to sleep

I have three external hard drives connected to my iMac in a FW800 daisy chain. It used to be, when I put my iMac to sleep, all three of the external drives would spin down and go quiet. I replaced the drive in the middle of the chain with a new one (both LaCie), and now none of the three external drives spin down when my I sleep my iMac.
Does anyone know how to get them to spin down?

It's a known issue for many many brands of FW800 drives. I've been reporting this to apple for a while. With 10.9.2, my particular drives will spin down if they are mounted and unmounted but if my system wakes from sleep which will spin up all drives, they stay that way until I mount and unmount again. So....10.9.2 is a little better but FW is still borked.
This is the primary reason my Mac Pro is still on Mountain LIon. My MBA is on mavericks. A note of caution...Mavericks writes to the NVRAM, sometimes when dual booting it is good to clear that memory.

Having problems putting iMac to sleep?

I've noticed lately that I have to click SLEEP two or three time to put my iMac into sleep mode. Is this the start of a bigger problem and what do I have to do to fix the problem. Any assistance will be appreciated.

See if something here helps http://support.apple.com/kb/HT1776?viewlocale=en_US
I'd also try resetting the SMC http://support.apple.com/kb/HT3964

Put iMac to sleep wakes up when wireless device switched off

Brand new iMac - click to put it to sleep but when switching off wireless keyboard/mouse it wakes up again to tell me it's searching for the mouse.

in my experience, if i switch off my wireless keyboard first, then make my mini go to sleep, it will not wake during the night.

What command or key combo are you using to put it to sleep?
Option-Command-Eject works for me. You have to hold the combo for about 1/2 second or more since the delay was put into the Eject key some time ago.

HT5549 trouble putting iMac to sleep after installing this update?

I can't put my imac to sleep anymore after installing the security update for Java. Is anyone else having this problem?

I had the download file open all the time and closing that has solved (looks like) the problem. However, this was not an issue while I use the regular mouse.

Power off after putting iMac to Sleep

Have you ever experienced this?
Put you iMac to Sleep and it powers down - not a shut down, but the power goes off - no blinking light, no whirring of the hard drive, no sign of life!
I have read and performed many of the tips regarding NVRAM, SMU, PMU, etc. resets. None have worked.
Situation 1-
Use the 'sleep' command - moments after the machine powers off.
Situation 2 -
iMac screen saver will run for a short time, then screen goes blank, the power light illuminates, the fan spins full speed, and the machine is totally unresponsive to mice clicks or movements, or keyboard entries.
Situation 3 -
Sometimes upon power up, the iMac doesn't start, but you can hear a faint buzz sound from the back of the machine. Similar to audio hum.
These problems occur whether or not other devices are connected to the iMac.
Connections-
Standard USB devices - mice, card reader,
Bluetooth keyboard
Ehternet
Power Settings-
Screen saver 5 minutes
Energy Saver - to sleep when inactive - 15 minutes, display to sleep - 15 minutes.
Various other settings tried with no change in problem.
I suspect the power supply. What's your opinion?
iMac g5 1.8Ghz, 1gig mem Mac OS X (10.4.9)

Any solution to this?

I began experiencing the same thing this week (two days ago). I also tried repairing permissions, resetting SMU, and removing the iTunes receipts (Library/Receipts) since this is what caused an earlier failure to sleep. The difference is then the computer would not sleep, now it shuts off instead of sleeping.
Situation 2 -

I have experienced this (Sit 3) as well with my LaCie firewire drive connected, sometimes. I have found that powering off the LaCie resolves this, as does unplugging it.

When I put iMac to sleep it disconnects with Airport Express

I have an Apple Imac 2.1 and a G4 laptop, and have no problems with either of them connecting to the internet, but my 2.93 Intel Core 2 Duo IMac is another story.
Whenever I put it to sleep I have to go through the full deal to reconnect it to the internet, so as, what is your password, which network would you like to connect to, etc.
How do I stop it doing this and behave like the other two, cause it's behavior is really pxxxxng me off. Could someone out there please help me to stop it doing this. thanking you

The AirPort Express does not "sleep", it's always "on"...so you have an iMac issue...not an AirPort Express issue. You may be better served by posting in the iMac Forum.
If you have not already done so, open System Preferences (gear icon on the dock) and open Network. Click on AirPort on the left and then click Advanced at the lower right. Make sure that your network name is at the top of the connection list so that your iMac will connect to that network first. Drag it to the top if needed.
Delete any old networks displayed that you no longer need by clicking them to highlight them and then clicking the - (minus) button at the bottom of the connection list.
Make sure that there is a check mark next to "Remember networks this computer has joined". No other boxes should be checked.
Click OK, then click Apply
Restart your iMac and see if that helps. If no luck, you should post in the iMac Forum for further help.

Putting iMac to Sleep

Hi I was wondering is there a way to keep ichat running even if u decide to put your computer to sleep.

Hi Jeff,
Nope.
A Mac's default action is to disconnect the Mac from the internet if not active (awake).
There was an Add-on for Panther iChat that does not work with Tiger that allowed you to post a permanent Away message when you were offline.
If you use Fast User Switching there is a setting in the General section of iChat preferences for making appear that you are Away when in fact you are not connected from the Mac USer. I hav not noticed that this effects the Sleep fuction at all in the way you describe.
Any Application that is open when the copmuter goes to sleep is not actually quit and in that sense is "open" but I don't think this is what you meant.
Because of the "restart"/Waking order of Apps and re-establishing the connection for the internet can cause some problems in iChat recognising that the connction is there.

Putting iMac to sleep with more than one user logged on

Hi,
Our family shares the iMca with an account for each member.
They all leave them looged on all the time and we switch between each.
I want to force th eiMac to sleep between mifnight and 6 AM to save power.
When I set this up in Energy Save settings within System preferences, it will not execute and comes back with an error saying that there are other users logged on and this may cause them to lose work.
Any idea how I can force this to over ride any objections?
Thanks

It sounds like you have scheduled it to shut down instead of sleep. Ensure you have selected Sleep and not Shut Down.

My nano's power button is jammed in. I can't wake it up to use the touch screen and I can't put it to sleep to save the battery. The only way to wake it up is to plug into computer. How do I get it unjammed?

The power button on my nano appears to be jammed. I didn't notice until I tried to check the distance on my pedometer while on a walk, because the music was playing fine. I just couldn't wake the touch screen to do anything. It plays fine. Anyone know how to fix this?

You'll need to get it serviced.

Hello all,
I have a 14.88G iPod Nano that I currently use as my primary watch. A week or so ago I started to experience a blank white screen when I press the "sleep/wake" button instead of the watch face (I have it set to wake from sleep to display the clock). When I hard reset it, it will come back fine and the screen will respond and work as normal, as soon as I manually put it to sleep by pressing the "sleep/wake" button and then try to wake it the same thing happens and I have a blank white screen that doesn't respond to touch gestures or anything.
What I have tried so far to no avail:
Numerous hard restarts (holding the "sleep/wake" button with the volume - button).
Tried this: iPod nano (6th generation): Hardware troubleshooting
Changed the watch face to display.
Recharged the device overnight (without full discharge).
Since none of this works I'm out of ideas. Eventhough I have a 6G Nano it should no longer be under warranty since I was sent it as a replacement for a different (older) product.
Any ideas? Is this a known problem? Thanks in advance for any insight any of you could provide. Also, what time is it??
Regards,

Hey,
I have the exact same problem as you have described. I also used my ipod as a watch but starting from today, whenever I unlock it the screen turns white until a reset is done. Even a factory reset through itunes didn't fix it.
Have you found any solution?
Bah, this is annoying.

What is the keyboard shortcut to sleep display on the Macbook Air?

On my Macbook Pro it's ctrl-shift-eject. There is no eject button on the Macbook Air so what is it?
Yes I know about Hot Corners. Yes I know you can turn the brightness right down. I want the keyboard shortcut.

Sorry for being a Johnny-Come-Lately to this thread, but I just found it.
I do not like using a Hot Corner (alone) because it is too easy to inadvertently sleep the screen by random movement of the the cursor. However, there is a solution....
You can add a "modifier key" (e.g., the "Command" key) to the hot corner sequence so that moving the cursor to the chosen hot corner does NOT sleep the screen unless you also push and hold the modifier key.
To add a modifier key, open "System Preferences", go to "Desktop & Screen Saver", choose the "Screen Saver" tab, and click on "Hot Corners…". Open the dropdown for the corner you prefer. Before clicking "Put Display to Sleep" hold down the Command key (or another modifier key*) and then click "Put Display to Sleep".
Voilà! Now the display will sleep only if you hold down the Command key before moving the cursor to the chosen Hot Corner.
*I believe the only modifier keys available for this are Shift, Control, Option and Command -- you can use any one of them or combinations.

Not putting Macbook to sleep

Macbook has gotten more sluggish with ML even with 4GB's of RAM when rebooting and waking from sleep. The solution has been not to put it to sleep (other than the hard drive) and this has greatly improved performance. But will this harm the Macbook more than puting it to sleep? The tech I spoke with suggested I do this as he said it would be better than putting it to sleep everytime I walk away from it.

On a full charge and put to sleep the MacBook's battery will last more than 10 days but less than 20. I know this because I forgot to turn my MacBook off before leaving for vacation this summer. I returned 20 days later and found that the computer needed to be plugged in before it would start so I know it won't last 20 full days. Over the winter holiday I intentionally put it to sleep before leaving and 10 days later when I returned it woke up showing under 1/2 a charge left. What I don't know is whether the computer's battery will be depleted on day 11 or in the middle of day 20 or somewhere between! Well, actually I do assume it is close to the 20 day mark than the 11 day mark.
So when should you sleep it as opposed to turning it off? I generally turn it off (when I remember) if I'll be leaving it for more than a week. This has been my habit since buying my first PowerBook back around 1991.
