Energy saver not putting my iMac into sleep mode

I've tried ejecting my firewire drives and other usb devices but cannot get the iMac to actually turn off per its energy saver settings. Screensaver and then screen shut off both activate per the energy saver settings, but the computer stays on. Only way that sleep mode is ever activated is if I'm in the login screen, or if I manually press the button on the back of the computer.
Would really appreciate it if anyone has a workaround to actually make my iMac sleep automatically. Never had this problem with my PC..

This might work for you and save a lot of head scratching. Sometimes these sleep problems just can't be figured out. I've used it successfully. Free

I am having the same issue but mine is with Netflix. And there are only 4 categories now on the main menue when there used to be 5. Something went crazy with ATV software.

After installing Mavericks, power button does not put my iMac to sleep.

After installing OS X Mavericks, the power button does not work as before, any help?
Thanks

CT, the behavior of the power button on Mavericks (10.9.2) is not as the note (OS X Mavericks: Using the power button - Support - Apple) describe. I have to press four or five times de power button in order to put the mac to sleep.

HT3887 My bluetooth devices will not wake my iMac from sleep mode.

My iMac will not awake using the bluetooth keyboard or mouse. I can use a USB mouse but bluetooth and network connection will not respond. I must restart the machine. This happens after several hours of being in sleep mode like all day when at work or over night. I have the system set to wake the computer with a keyboard or mouse click. THis works only when in sleep mode for an hour or two.

Smart Cover doesn't put iPad into Sleep mode in Unlock position after iOS 8.3 update

Prior to the iOS 8.3 update, closing my Smart Cover would put my iPad into Sleep mode when in the Unlock position. Since the update, this function no longer works in the Unlock position. In the Lock position, I hear the click and the iPad does go into Sleep mode. Since I am the only one using my iPad, I don't need it locked when at home. Has anyone else experienced this problem?

hi guys. i'm back.
i solved my problem. i refer my iphone 5 to a local distributor. a repairman checked my iphone and i described my problem. he checked my battery. it was fine! then after an hour excavation around hardware solution he told me that the charging kit crashed because of heavy mobility usage!
yes. i did not covered my phone with any cover. the cpu pressure by ios update crashed the kit! now my phone get back after the kit changed and work finally. i restored my phone to ios 8.2 now.
i'm going to buy new iphone. but i'm really confused if such this issue really happened for iphone 6 too!!!!!
i'm totally disappointed .

MacBook Pro shuts down when put into sleep mode

Every time I put my Mac into sleep mode (plugged in or not, charged or not), it shuts itself down, and I have to restart it. I just got it (brand new) in August, so I know the battery shouldn't be bad.
It's been doing this for about a week... I just changed to Snow Leopard yesterday, and downloaded the software updates and everything, but it still shuts down.
Anyone know what I can do (short of sending it to Apple) to fix this?

Okay, well I already used smartsleep.
It fixed the problem I was having, but now my macbook started having the same issues again this weekend. It's happened twice tonight in the span of 3 hours.
Do I need to uninstall SmartSleep then?
And here is the report I get when the macbook reboots:

Severia,
I tried your solution, but it did not work with my laptop. After I restart the laptop, the language does not change and I cannot type the password in English language. Do you have any other suggestion?
Thank you.

Mini goes into sleep mode after login on

I put my mini into sleep mode after logging out. Then, when I log back in, after a few seconds, it goes into sleep mode again. I have to re-awaken it.
This is not the way the computer should work.
Is this a configuration issue, any ideas????
I use Apple's bluetooth wireless keyboard and mouse combination.
Thanks

It sounds obvious but are you sure your power adapter is ok and the battery is charged. The behaviour sounds a lot like low battery sleep.
Press the check button on your battery pack - do you get plenty of lights?

Toshiba Satellite L505D wont go into sleep mode. Freezes before power light blinks yellow.

When i try to put my laptop into sleep mode by closing the lid, it freezes before it enters sleep mode. i get a black screen when i pick the lid back up, and the power light stays green, instead of blinking yellow like its supposed to. Last time i remember it working properly was around June 6th, i took my laptop to my buddy's place so we could watch the new Halo 4 trailers and i know it worked properly on both the car ride over and the car ride home. anyone have any ideas whats wrong?

Let's make some experiments.
What happens when you boot into Safe Mode?
Start your computer in safe mode
Also, what happens when you boot normally into another account? If necessary, create one.

Imac keeps putting itself into Sleep Mode.

This morning my Imac has put itself into sleep mode twice within an hour - losing everything I was working on. It just goes black and then loads the log in screen.
I've never had this issue before, it's not over heating (not sure if that could be a problem) it's not full up, it's not lagging it's just this problem.
I really cannot afford the time to take my Imac into the store for repair unless ofcourse it's really needed. Can someone help please?
Thank you,

Hi Tori,
Unfortunately I'm unable to help, but I want to add that I had exactly the same problem this morning (Jan 13, 2013)! It was putting itself into sleep mode twice within 5 minutes.
In contrast to TorkiClarkson, the fan of my iMac was blowing hard, but that happened a lot the last months without falling into sleep mode. Actually I'm a bit afraid I've got a heating problem since my warranty of 1 year has experienced..
Hope someone has valuable information for TorkiClarkson and me.
Thanks.

James did you find a solution? Last night my daughter put her Macbook Pro to sleep and now it won't turn on or charge? I think it is not charging because the light does not come on. We charged mine and the light came on and worked so it is clearly her computer. Help!!!

Early 2008 iMac (8,1) randomly goes into sleep mode

Hey,
My early 2008 iMac (8,1) on 10.8.2 goes into sleep mode by itself. I've played around in Energy Saver, tried resetting SMC, NVRAM, replaced HDD, reformatted HDD, installed smcFanControl, reinstalled Snow Leopard, Lion, Mountain Lion. None of that worked. Took it to the Genius bar, performed some diagnostics tests and they said everything worked properly. Does anybody have the same problem? I can still use the computer for general computer use (light web surfing and e-mailing), but it seems to go into sleep mode when I have a lot of applications open and especially when watching videos. I've tried researching this problem, but I've haven't found a definitive answer. Right now, the Genius that I've been talking to thinks it may be the RAM. I'm waiting on new shipments of test RAM to arrive at the Apple Store for him to properly diagnose.
Thanks,
Jason
iMac (8,1)
2.8 GHz Intel Core 2 Duo
2x2 GB 800 MHz DDR2 SDRAM
ATI Radeon HD 2600 Pro 256 MB
1TB 7200 RPM SATA ST1000DM003-1CH162
If you want to read the whole time line, I've included it here. I apologize for it being so long.
At first I was running Lion (10.7.5) and the computer would enter sleep mode whenever I was doing anything with video. For example, watching YouTube videos and chatting on FaceTime. And funny enough, I distinctly remember watching a bunch of movies with VLC and the computer did not go to sleep (Although, this is not true anymore). I could wake the computer up and use it, however within a few minutes the computer would re-enter sleep mode. The computer seemed fine and I could access all of my files. Tried resetting SMC and it did not resolve the issue.
I made a Genius appointment to see if they were familiar with the issue. The iMac passed the in-store diagnostics test; it said all the components were functioning properly. He told me to bring it home to do a fresh re-install of my OS and then run my computer to see if the problem persisted. I took it home and reformatted my HDD with a 35-pass erase, re-installed Snow Leopard (10.6.8) and declined to transfer any backups from Time Machine. I was using a fresh system and sure enough, the problem persited. Tried doing the same thing again but with Lion (10.7.5) and still no luck. So I made another appointment and it passed the in-store diagnostics test again. I let them keep the computer for a 24-hour diagnostics test. They told me they would diagnose my computer with the OS on my HDD as well as a copy of OS that the Apple store deemed 'good' on an external HDD. The Genius called me and told me that my HDD failed their 24-hour diagnostics test and recommended I replace it. I initially had a 750 GB HDD, and the Apple Store could only offer me a 500 GB HDD ($200). I opted to take my computer to Carbon Computing, an authorized dealer in Toronto, to have a 1 TB Seagate HDD ($170) installed with no OS on it. I brought it home, performed another 35-pass erase and installed Snow Leopard. Problem still persisted. Repeated with Lion, still unsuccessful. Looking back, I was so excited that I just had to replace the HDD to fix the problem, I forgot to ask the guy if he could recreate the issue.
I began to suspect that it was a heating issue. So I installed Temperature Monitor and smcFanControl, and cleaned the fans as much as I could without taking the computer apart. Without smcFC on I tried to recreate the problem and I noticed that the Power Supply Position 1 reached 95 degrees Celsius, and Graphics Processor Temperature Diode reached 97 degrees Celsius before entering sleep mode. I don't know much about temperature sensors and what they monitor specifically, and so I couldn't draw any conclusions from that data. I turned on smcFC and cranked the optical drive speed to 2000 RPM, HDD to 3000, and CPU to 3000. The computer still went to sleep but the temperatures were below 90 degrees Celsius before entering sleep mode. I've tried researching here and on the internet about normal operating temperature ranges of iMacs and generally found that most do reached that temperature but they do not go to sleep mode.
Then I thought it may be a problem with Lion so I upgraded to Mountain Lion. The issue still persisted. Tried resetting SMC and NVRAM, did not resolve issue.
I called the same Apple Store explaining to them that their recommendation of replacing the HDD did not resolve the issue. They told me to bring it in and have them check it out again. I went through the same process I did before; the iMac passed all of their diagnostic tests. The Genius told me this time he will test out the RAM. He called me and told me that he could replicate the problem and so he proceeded to put in a stick of 'good' Apple RAM, but the computer would not work. He said the 'good' Apple RAM was damaged, either before or in the process of putting it in. He plugged in my old stick of RAM and the computer worked. He tried to recreate the problem and claimed that the computer ran for over 24 hours with an existing movie on my HDD playing and it did not go to sleep mode. However, once I brought it home I played the same movie right away and it turned off 17 minutes into the movie. Tried resetting SMC and NVRAM again, ran the movie again, still went to sleep.
And that's the story for now...

Now to find out WHY it does it at home only. How hot is it at home? Have you checked the AC current/voltage at home?
Well they were able to replicate the issue at the Apple Store the second time I left my computer there. Anyway, we don't have any heating on at my house at the moment. It's usually from around 20-23 degrees Celsius (72-75 F). Temperature Monitor says ambient temperature is 30 degree C though...
I'm not really sure how to check the AC current/voltage at home, but my computer worked before I moved it. So I'm not sure if that is the issue.
I normally only have speakers set up to my computer and a wired keyboard. The speakers are powered separately. I would assume that at the Apple Store only the power cord and wired keyboard are connected.
What is the Power Supply Position? And what does it do?
Thanks for your help!

Can't put the computer into sleep if VPN is connected

I think I have found a win7 bug. The problem is that I can't put my computer into sleep if VPN is connected. The VPN client I used is Microsoft VPN client. The VPN works fine. But if I click sleep button with VPN connected, the computer screen turns
black, the fan speeds up, and the signal light tells me the computer is still on, not in sleep mode. When I try to wake up my computer by tapping the enter key, space, or moving the mouse, it just doesn't work at all: the fan speeds faster and faster
and the computer heats up. The only thing I can do now to save my computer from darkness is to hit and hold the power button, powering off the computer. The sleep function works just fine if the VPN is disconnected. I can easily wake my computer up by tapping
the enter key. I don't know whether this problem is only present on my computer or universally present on all win7 computers.
The following is my system info:
OS Name Microsoft Windows 7 Ultimate
Version 6.1.7601 Service Pack 1 Build 7601
OS Manufacturer Microsoft Corporation
System Manufacturer LENOVO
System Model IdeaPad Y460
System Type X86-based PC
Processor Intel(R) Core(TM) i5 CPU M 460 @ 2.53GHz, 2534 Mhz, 2 Core(s), 4 Logical Processor(s)

Hi,
Please collect the report for the further troubleshooting. Note:Please do the following steps when VPN is connected.
1. Click Start, type in “cmd”, right click it and choose “Run as administrator”.
2. Type in the following command.
Powercfg –energy
3. Find the report file in the location showed in Command window.
4.
Upload it.
