Sleep, Energy Saver Troubleshooting

As one can see below, I have an Acard 6280M and I believe it's generally conceded that they cause sleep and Energy Saver issues. My issue:
1. Will NOT shutdown automatically at night as scheduled; so, I shutdown manually or it might be asleep all night after I manually sleep it.
2. WILL awaken from sleep or from shutdown in the mornings, as scheduled.
(I've made Macaroni inactive; din solve anything.)
3. Will NOT sleep automatically (set for 'after idle for 25mins'). Monitor will sleep and monitor will awaken with the press of any key on the keyboard. HDD does not sleep.
Actually, #3 is my main concern; I've lived with 1. and 2. for a while, but 3. is a fairly recent, persistent phenomenon.
Given that Login items can cause sleep issues, I ran in Safe mode and that did not solve the problems.
I'm quite ignorant about Activity Monitor. Here's the top few lines from running Top; very similar to what I see in Activity Monitor; with no apps running/active far as I know:

Periodically, about every 50-60 seconds, two items pop up for only a second or two:
'sh' and 'python' (monitoring this stuff is like watching grass grow). Also, at CPU Usage, User will jump to 43% and System to 50%, just for a second or two. Notice at the top, "2 running". Yesterday, it also showed "1 stuck". I ran TTPro 'advanced' and today there's no 'stuck' process. In Activity Monitor, I also quit 'WindowServer' which was persistently showing up. However, the failure to auto-sleep persists. I've had this deal before and a restart usually solved it. I also started from my other drive and downloaded the latest Acard driver. All to no avail. Any ideas will be greatly appreciated!
Dave

Hans,
Okay, in Energy Saver, "...HD sleep is deactivated as I have PCI cards installed..." That isn't right, Hans. DId you install a driver before card installation? One should never lose the ability to at least manually sleep, even with PCI cards. You might want to start a thread of your own.
I've read through about 10 pages of "sleep" threads here in Discussions (and there must be about 50 pages of em!). Sleep issues are very wide spread, particularly with laptops. I even read one where the user got a new iMac from Apple. Where do I sign up for that?! Again, kinda hoping someone could shed some light on the Activity Monitor and Top activities. MIght not be the problem at all, but they seem odd.

Sleep (energy saver) during long upload

I'm doing ~4 hour upload.
If this is all that's going on, is the computer considered "inactive" causing it to go to sleep after the specified time in system preferences->energy saver?
If the computer does go to sleep then there are the following questions:
a. Will the upload continue while the computer sleeps?
b. Is there some risk that the sleep will also turn off the airporter?
c. To improve the probability of not have any side effects from the computer going to sleep, should I disable this feature during my long upload?

Greetings and welcome to the Apple boards.
a. The computer should not go to sleep if a download is occurring. The screen saver may kick in, but the network activity should keep it from actually sleeping.
b. Sleep probably would turn off the AirPort card.
c. Definitely you can do this.
As an experiment, set the computer to go to sleep after 5 minutes or so, start a download and see what happens.

Does iPad Air have a sleep/energy saver mode?

Hello~
I just bought this iPad (first one) and can't find anything about a "sleep" or "battery saver" mode. I don't want to turn it off, but I don't need it sitting there glowing. Plus, can't that hurt the screen?
Thanks!

OMG. I feel like an idiot. I've looked everywhere, but for some reason never opened that menu item. THANK YOU SOOOOOOOO MUCH!!!!! You ROCK!!!!

Sleep Disorder (Energy Saver Prefs)

I tried in the hardware section about this, maybe I can get some help here:
My new Intel iMac seems to have a sleeping disorder. Does anyone out there have the Information Technology equivalent of Ambien CR?
I have my Energy Saver Preferences set to 22 minutes to put the system sleep and 15 minute to put the display to sleep. It doesn't seem to work.
Also, if I just put my iMac to sleep manually using the menu command in the Finder, it will go to sleep initially, but when I come back a few hours later it is on -- not sleeping. Am I going to have to shut this thing down whenever I'm not using it?
1) I have checked the box "Put the hard drive to sleep whenever possible" in the the Sleep Pane of the Energy Saver System Preferences
2) In the Options Pane of the Energy Saver System Preferences under Schedule there are NO active settings to start/wake my iMac.
3) I have disconnected my external hard drives and my Wacom tablet to see if that made any difference. It did not. the only other peripheral is my Apple USB Modem, which I need to connect. I am not connected when I attempt to put the system to sleep
I have both put the computer to sleep and come back several hours later to see that it woke up. On another occasion I was reading on the sofa in the same room with the iMac and saw it wake up. When I saw it wake up there was no noticeably external noise or vibration in the house which might have caused it to wake up. It just woke up.
What is the point of even having an Energy Saver Preference if it doesn't work?
Does anyone have any more suggestions for troubleshooting this?
Intel iMac Mac OS X (10.4.7) 2 gig DDR

Hi, Wet Baloney.
1. Trash all the energy saver preferences:1. Quit System Preferences if it is open.
2. Open the Computer > Macintosh HD > Library > Preferences > SystemConfiguration folder.
3. Trash the following two files therein:• com.apple.PowerManagement.plist
• com.apple.AutoWake.plist
You may be prompted for your Admin password when you trash these files.
Note that the second file is only extant if you have used the Schedule option to schedule startup, sleep, or shutdown.
4. Empty the Trash.
5. Launch System Preferences and reset the Energy Saver preferences accordingly.2. re: Modem:• In the Options tab of Energy Saver preferences, if "Wake when modem detects a ring" is selected (checked) deselect (uncheck) this option.
• In the Print & Fax Preferences > Faxing tab, deselect "Receive faxes on this computer" if selected.With those options selected, I've seen my sleeping Macs wake up if a phone line was connected to the computer and a call came in on that line.
Good luck!

Energy saver settings - weird sleep behaviour

I have customized Energy saver with the following:
When power Adapter: display sleep 5 min, computer sleep 1hr
When battery: display sleep 3 minutes, computer sleep 10 minutes.
This works when I first boot up my Mac. However after the first sleep things get akward, it almost seems to me that MacOSX has swapped these two settings.
Symptoms: I rebooted my Mac this afternoon. I unplug the power cord. The Mac goes to sleep after 10 minutes.
I wake the Mac. I leave it still. The screen stays on unusually long. After 20 minutes the Mac is still not asleep as it should be. It usually remains like this until the next complete system reboot.
This gets annoying when on the go and energy saving really is needed...
What is happening? Any weird settings file corrupt from previous versions of the system?
All suggestions welcome...

1. You wrote: " the system doesn't shut down at all (an hour after I left the room) when it's supposed to shut down in 4 minutes, as currently set."This is the first you've mentioned about a problem with shutdown, which I would presume to mean a problem with "scheduled shutdown." Previously, you were writing about sleep.
Are you confusing "idle sleep" with "shutdown" in your post? Let's clarify what you mean by "shut down" in the quote above.
2. If the problem is idle sleep, then see "Mac OS X: Why your Mac might not sleep or stay in sleep mode." In addition to the causes cited therein, and the corrupted Energy Saver preferences we discussed earlier, some other common inhibitors of idle sleep include:
• Runaway processes incessantly writing to Console logs will keep the hard drive active and prevent idle sleep. Vendor-provided software included with HP All-In-One devices and Canon scanners are common culprits, but other apps have been known to continuously write to Console logs. See my "Checking Console for clues" FAQ and look for repeating blocks of messages being written at high frequency.
• Classic Sleep. If you're running Classic apps, be sure that the "Put Classic to sleep when it is inactive for…" slider is set to other than Never in the System Preferences > Classic > Advanced tab.
3. If the problem is with scheduled shutdown, how that works depends on the version of Mac OS X 10.4 you are using. See:• If 10.4.5 or earlier, see "Mac OS X's Shut Down schedule will only work when one user is logged in."
• If 10.4.6 or later, see Mac OS X 10.4.6 or later: Scheduled shut down occurs at Login window even if users are logged in."
Note that your Mac must be awake at the appointed time for scheduled shutdown to work. See "Mac OS X 10.3 and later: Computer must be awake for scheduled shutdown to occur."
Good luck!

Hard drives sleep - not energy saver settings

I have two(2) different Quad 2.7 Pro Mac computers, both with 2 500GB Seagate drives mirror raided internally and Sonnet Fusion D500 SATA enclosures with 5 500GB seagates RAID striped.
They all fall asleep after inactivity, and it take several seconds for the drives to spin back up. The energy saver is set to never. I even tried turing it on, restarting, turing it off, reseting, but it did not help.
I've removed the internal RAID and the external still sleeps, and vice versa.
My only thought is it it the seagate drives. They are refurbished baracuda 7200.9 drives.
Any ideas?

hello,
i'm experiencing the same issue. i have 4 internal raptors in RAID0 and 4 external WD drives in a PM enclosure and have found that they too sleep as you mentioned.
i checked the energy saver and the box is unchecked to "put drives to sleep when possible" also...
i installed Leopard the other day when i got the new enclosure and external equipment - clean install - so i don't know if it would do the same in Tiger...
any suggestions, or is this normal for exterior storage - regardless if it is SATA or not?

Mac Sleep Timer (through 'Energy Saver' in System Preferences) won't work

Hello,
I have a MacBook (13-inch, Mid 2009) running Mac OS X Snow Leopard 10.6.3,
and it has been installed with the latest software updates possible.
(The latest update is the 'Security Update 2010-003')
Previously I was using Mac OS X Leopard 10.5 on my MacBook,
and I can vaguely remember the timed computer sleep through Energy Saver would work.
That is, when the counter's time matches the amount of time I specified (e.g. 10 minutes), the computer enters sleep mode and displays a pulsing power light.
After upgrading to Snow Leopard I can barely remember the scheduled computer sleep will work as I don't really notice how it sleeps / I will shut down my MacBook before I go to bed.
==========
However, last night I was really tired and slept in front of my MacBook unconsciously.
When I woke up, I found that my MacBook didn't display a pulsing power light but a continuously-growing power light.
I tapped the trackpad and the display turned on, so I knew that my MacBook didn't go to sleep a whole night.
*What that means is that the Sleep Timer (through 'Energy Saver' in System Preferences) won't work.*
But the timed display sleep DOES work.
==========
After spending a whole day Googling,
I found that there are plenty of people suffering the same problem as me, although their Macs and OSs vary.
I also found an official support page from Apple concerning the related issue:
Mac OS X: Why your Mac might not sleep or stay in sleep mode
http://support.apple.com/kb/HT1776
I tried the following methods but still can't resolve the problem:
_- boot my MacBook in safe mode_
_- use the 'Disk Utility' to repair Disk Permissions through booting my MacBook from the Mac OS X Snow Leopard Installation DVD_
_- reset NVRAM (Intel-based) (as PRAM is used by PowerPC-based Macs)_
_- reset SMC (System Management Controller)_
NONE of the above-mentioned methods can resolve the problem.
Althought I am sure that the Spotlight isn't indexing the hard drive, and I just start my computer and do nothing and wait for the scheduled computer sleep, the scheduled computer sleep just won't work.
In the other Mac forum, I saw someone suggest installing an application called PleaseSleep:
http://www.dragonone.com/products/macosx/pleasesleep/
It works.
But I really want to find out what caused this problem as this is a function shipped with Mac which is expected to work normally.
What's more, Apple is claiming to be a green Apple, right?

Looking forward to your replies! Thanks in advance!

Found this discussion by googling "com.apple.systempreferencescouldn't find any matches"...
One month ago I bought a brand new Macbook Pro 13", and after a couple of weeks I realized it wasn't sleeping on its own when it should, per the system preferences. (I did sleep when I chose "Sleep" in the menus or closed it... It just wouldn't sleep on its own, while open.) What was extra frustrating was that it was intermittent... It would sleep on its own maybe 1/3 of the time, but other times it would NEVER go to sleep. I deleted PowerManagement.plist, reset the SMC, etc... No luck.
I took it to the "geniuses" at the Apple Store, and the guy took all of five minutes trying to diagnose the problem. When my MBP wouldn't sleep on its own, he promptly replaced it with a new one. That was nice, but I actually would have preferred that he diagnosed and fixed it. (I think the store was so swamped with people coming in for service that day that they were doing anything they could to close cases and get customers out of there ASAP.)
Now, sitting here with my 48-hour-old MBP, I still have the problem. The other one was so new that I had barely put anything on it yet. The only applications I had put on it were MS Office for Mac 2011, Firefox, Chrome, and Adobe Flash Player. I've put Office and Flash Player on this one, but not yet Firefox or Chrome. That's it. No other customization or fancy business.
I looked into the Console just now, and I see the "Couldn'tfind any matches" entry popping up again and again. The last three seemed to pop upright around the time when my MBP should have gone to sleep on its own, but not down to the second, so it's hard to definitively point at that and say it's it for sure.
They need to fix this!!

Will Not Sleep In Energy Saver Mode

My iMac G5 20" 1.8Ghz will not sleep when I set it to sleep in the energy saver panel. This just started for no specific reason a few months ago. It will sleep fine when selected from the Apple menu. I have been through the discussions and no one seems to have a good fix for this. I have repaired permissions, reset the PRAM and SMU, and tried all the different configurations in energy saver. I called AppleCare and they seemed not to know anything about this issue. They recommened an archive and reinstall of the operating system. I feel this is kind of drastic for this and I have not yet tried it unless I can see that other people have done it and it works. My computer is in the repair program for the power supply problem and it has an updated power supply since the original actually smoked and Apple replaced it. I was wondering if anyone out there has had this same sleep issue and got it resolved?

Well I finally decided to try and delete an application that I suspected could be a problem not allowing my computer to sleep automatically. That application is LAST FM a music service from the UK which is actually quite good. I suspected it was a problem since it would always launch when I opened iTunes and asked if I wanted to share my iTunes library with the LAST FM group which I did not. I selected I did not want to share in the LAST FM preferences but it still opened anyway when I launched iTunes. I deleted the program and repaired disk permissions and *It Worked*, my computer will now go to sleep with the settings I selected in energy saver. I know there are other people out there with this problem I would first look at this application and others that are probably running in the backround causing your computer not to sleep automatically. I am a firm believer in trying to work up from the easiest solution before taking the drastic approach, such as a system reinstall, or a logic board replacement. I did take Nikki's suggestion seriously. My power supply had been replaced in the repair program and my logic board did not meet the criteria for replacement since it was not exibiting the symptoms that required its replacement such as video and power problems.

Mac mini won't auto-sleep (via energy saver)

I've tried almost everything! SMC reset, PRAM reset, scheduled works fine but the energy saver settings don't. I'm only getting a screen shut but the little lamp in the mini does't fade in and out. help please.

I'm having the same problem. I just got my Mini this weekend.
After setting it up initially, the energy saver sleep worked fine.
And I haven't installed too many things since. I did an upgrade of various mac apps through the software updater and I installed a shutterfly plugin for iPhoto but nothing else really.
I didn't notice exactly when it stopped working.
The only thing I have connected via USB is the mouse/keyboard/speaker through KVM.
Even though I had those from the beginning, I'm going to try connecting them directly to the mini.
Other than that, I only have a network share setup with my Windows machine.
Any updates from the OP or others with the same problem would be great if you've gotten yours fixed.

Computer won't sleep on Energy Saver mode

All of a sudden, the computer will not sleep while on Energy Saver mode. Any ideas on how to locate the culprit?
Thanks!

Hi, seb29. One possible culprit is a fax software setting: if the computer is set up to receive faxes, it either won't sleep at all or won't stay asleep for long. In the Print & Fax pane of System Prefs, click the Faxing tab and make sure "Receive faxes on this computer" is not checked.

IMac late 2013 does not have "Computer sleep" setting in Energy Saver prefs

I seem to be missing the "Computer sleep" setting in my Energy Saver pref window. All I see is "Turn display off after" setting. The computer does go to sleep.Is this a change that was made for recent iMacs?

It appears that the chip manages the power states itself. Again getting exact information on this is a pain and I'm really surprised (well maybe not so surprised) that Apple hasn't said anything about this. You'd think if they make such a drastic change to the system and to the Energy Savings pane of System Preferences there would be something.
From http://www.itpro.co.uk/desktop-hardware/19655/intel-haswell-release-date-and-spe cs-revealed#ixzz2iJsWa73p
Haswell chips will have 3 power states, compared to two in its predecessor, Ivy Bridge. These will be Active, Sleep, and Active Idle. Intel claims the advanced power saving will help give it at least 20x power consumption improvement over third generation chips.
It appears that the CPU will put itself to sleep if it is inactive for so many cycles. In a way this makes sense, the old method of telling the system to sleep after so many minutes is really very imprecise.
The only reason not to put the system to sleep as soon as it is idle is that it takes some amount of time to wake-up. So the lag would be annoying if it happened each time the system was idle. With the Haswell chip (as near as I can make out) wake-up is almost instantaneous. So there is no lag going from sleep to running. With no lag then it becomes feasible to put the CPU to sleep sooner and more often.
Again there is nothing I can point you to that states this it's what I've pieced together from various sources. In any case the missing setting in System Preferences is not an error so I guess you'll get to experience fist hand how this all works. Post back with your observations, it will be interesting to hear what you think.

Mac does not sleep after setting Energy Saver settings

Hi, got a slight problem after installing Leopard. The thing is that my Mac seems to ignore the settings specified in Energy Saver Preference Pane, the screen is put to sleep as it should, that's working fine, but the computer does not go to sleep when designated. I can put it to sleep manually (or by using Schedule) but setting an inactivity time doesn't work.
No visible console messages or similar, no external HDDs or other external devices, no bluetooth, no file sharing, no bad apparent application/process running, no spotlight indexing, as you see I have tried a few things to fix the problem...
Any ideas of how to fix this problem would be appreciated. Thanks.

Ok, seems like I fixed the problem, the numerous things I tried must have solved it, probably the SMC or PRAM/NVRAM fixed it, though I'm not sure, but anyway it's working now, so I'm good.
And to asphotos: No I don't have any printer at all, and I don't use airport, not sure what caused the problem really, just appeared after Snow Leopard install... Thanks for the tip though.

Screen saver + Energy Saver (Computer Sleep + Display Sleep) won't work since Mavericks

Howdy,
Sorry to bother you.
My computer: iMac (21.5-inch Mid 2011), Mac OS X (10.7.3)
It took me some time to upgrade to Mavericks, but I did it eventually.
After having some problems with Spotlight (which was infinite looping indexing... and I just had to turn if off from Terminal), I realized I was encountering another big problem to me since the installation of Mavericks.
In System Preferences:
- 'Desktop and Screen Saver > Screen Saver' : it is set to 1 minute;
- 'Energy Saver > Computer Sleep' : it is set to 10 minutes;
- 'Energy Saver > Display Sleep' : it is set to 5 minutes;
- 'Energy Saver > Put hard disks to sleep when possible' : it is checked.
- 'Energy Saver > Wake for network access' : it was checked. I unchecked it. Nothing changes.
- 'Energy Saver > Start up automatically after a power failure' : it is unchecked.
- 'Energy Saver > Allow power button to put computer to sleep' : this option is absent from my System Preferences > Energy Saver, but I would like it.
So, before Mavericks, everything was working great.
Now, after 1 minute, or after 5 minutes, or after 10 minutes: it's all the same. Nothing is sleepy. Nothing is energy saving.
I did not change anything in my computer since I've updated to Mavericks. However, I changed Wi-Fi. Since it was the only new change, I've "played" with 'Energy Saver > Wake for network access'. When I opened my System Preferences, it was checked. I unchecked it. It did not change anything. I'm not sure what it's used for.
I would appreciate any advice to make it work as it used to.
Thanks for your time reading and typing your answer,
Have a good day,
Regards,

- 'Energy Saver > Allow power button to put computer to sleep' : this option is absent from my System Preferences > Energy Saver, but I would like it.
Built into the Software now.
Do a backup.
Quit the application.
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
Restart, open the application and test. If it works okay, delete the plist from the desktop.
If the application is the same, return the .plist to where you got it from, overwriting the newer one.
Thanks to leonie for some information contained in this.
You might try Spotlight again. That is how the App Store knows what is installed.

Energy saver keeps coming unlocked... sleep won't work

I've noticed when I arrive in the morning that my Mac Pro is awake. But the Time Machine log shows it had been an entire hour since TM was active.
I researched various places (including here) and deleted the preference for com.apple.PowerManagement.plist.
But the problem persists. What's more mysterious is that even though I lock the energy saver padlock, when I go back the next morning it is unlocked.
Any idea what's going on here?

Test after each of the following steps that you haven’t already tried:
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.
Note: If FileVault is enabled under Mac OS X 10.7 or later, or if a firmware password is set, you can’t boot in safe mode.
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.

Mac Mini won't sleep automatically using energy saver

I can't make my mini sleep using energy saver. The monitor will go to sleep the mac continues to stay on. I can manually put the mac to sleep by pushing the power button or by selecting sleep in the menu options. This occurs even if nobody is logged in.
I've tried unplugging all USB, Firewire, and Ethernet devices. That made no difference. I assume it has to be an application that's running continuously in the background, but I don't know how to narrow it down to the right one.
Suggestions?

You can try using Utilities > Activity Monitor to see what processes are most active, also look at Disk Activity.
