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.

Machine goes to sleep faster than Energy Saver settings

Hi all,
(I've searched for existing threads aboutthis but couldn't find any. Hope I'm not "re" posting)
I use my laptop (MBP 2.4, 8gb, INtel Core i7) to play music live, so I need it to not go to sleep for at least... 30-40 minutes as I will frequently not touch it directly for that long as I'm busy playing my instruments. But it goes to sleep consistently after about 10 minutes even though I've got the display set to sleep abfter 1.5 hours and the computer to sleep after 2 hrs.
Then I noticed the same thing on my Mac Pro in my studio. Same Energy Saver settings, still goes to sleep after about 10-15 minutes. Which means I have to re-enter my password there too. Same thing on my older MBP. Theyr'e all on Lion 10.7.4.
This is very annoying. Anyone know what I'm doign wrong?
Huge thanks!

I'm not sure why Energy Saver is doing that, but you may want to download Caffeine from the Mac App Store. It's a menu bar application that you can click and unclick that, when clicked, keeps your Mac on until it is unclicked or if you close the laptop lid/manually put it to sleep.

Still sleeping even after setting Energy Saver to Never

I'm trying to use my 2.53 GHz (Late 2009) MM as a server but even after setting the 'Computer sleep' preference to 'Never' in the Energy Saver System Preferences panel, the MM still goes to sleep. This isn't a big issue for me since I can and have used Wake On Lan apps/scripts, but it's a major pain in the you-know-what for other people who need to access this server over the internet.
Could there be some persistent overriding preference somewhere that is allowing this MM to go to sleep when in fact it should not be because of my setting? I've searched but can find anything.
TIA for any help with this.

Interesting... I had an EyeTV that I did install on an older G5 PowerMac that I stopped using before I migrated to this MM back in March. I'll check to see if the EyeTV app was also migrated over and uninstall it if necessary.
I would have thought that the EyeTV software would default to a "Never Sleep" state considering it's purpose. I'll check this possibility out when I get home after the long weekend.

Mac does not sleep under second internal HD

I got a problem with the Mac not going to sleep while running from the second internal HD under Mac OS 10.4.10. It remains awaken after a period of inactivity.
I have two HDs, one is primary and the other is second (only just installed last spring). The primary HD can go to sleep after a period of inactivity but if I click on "Sleep" from the menu's dropdown, it wouldn't go to sleep.
Anyone who have two or more HDs with Mac OS installed have this problem of Mac not going to sleep after either a period of inactivity or by clicking on "Sleep" from the menu?

Our Digital Audio G4 won't sleep after I installed a Western Digital 80GB drive. Neither the drive nor the display will go to sleep (although the clock freezes which may indicate that the CPU sleeps.)
If I boot from the original Maxtor 30GB, it sleeps normally but it makes no difference if the WD drive is Master or slave or if the Maxtor is removed - the computer will not sleep if it boots from the WD. Upgrading Tiger 10.9->10.4.10->10.4.11 did not help.
Since this G4 is 'improved' - 1GHz CPU, 128Mb video card, I'll probably replace the original video card and see if that does anything. Apple's Sleep documents warn that non-Apple installed drives may or may not sleep. But, since the vendor (OWC) does not report that other purchasers of the WD80 drive have sleep problems, I have to assume that it's unique to our configuration.

Lead Selection does not work after setting filter for ALV.

Hi, Can you please suggest on below scenario :
I have a Node with a sub node in it .
I am using the supply function on Sub Node to retrieve the date based on Parent Node.
There are two ALV's to display parent and item data. The issue is when a filter(user defined filter) is done on Parent table, the supply function does not work. The value is that of the selected row before setting the filter. Even after removing the filter, the item data is stuck and does not change on Lead Selection.
One thing I noticed is if the child table is a table UI, there is no issue. The only problem is when the second table is ALV
Thanks In Advance

Hi Prashanthi,
Your issue can be resolved as below
Create an event handler method 'set_alv_data' for the event 'ON_LEAD_SELECT' of parent alv
Write the below code inside the event handler method
METHOD set_alv_data.
DATA lo_node TYPE REF TO if_wd_context_node.
DATA lv_path TYPE string.
DATA lv_index TYPE string.
lv_index = r_param->index.
CONDENSE lv_index.
CONCATENATE wd_this->wdctx_my_parent_node
lv_index
wd_this->wdctx_my_child_node
INTO lv_path SEPARATED BY '.'.
lo_node = wd_context->path_get_node(
      path                          = lv_path
DATA lo_interface TYPE REF TO iwci_salv_wd_table.
lo_interface = wd_this->wd_cpifc_alv_child( ). "get the ref of alv comp of child
lo_interface->set_data(
    EXPORTING
*    only_if_new_descr =
      r_node_data       = lo_node
ENDMETHOD.
The above code sets the data node of child alv based on lead selection of parent alv data.
Note: Replace 'parent_node', 'child_node' with your nodes & 'alv_child' with your alv component name of child alv.
If you want to control the data of child alv on filter function, you can use the event ON_STD_FUNCTION_AFTE and once you define the filter you get the r_param->id = 'SALV_WD_FILTER_DEFINE' & now you can clear data of child alv.
Hope this helps you.

Rama

Macbook air does not sleep after closing the lid or putting into sleep

I've searched the message boards and external sites for answers and even spoke to Apple support. I'm so frustrated because it affects my work everyday. Its a 2013 Macbook Air running 10.9.2 and file vault. I close the lid or force into sleep mode and the system stays on even though the display goes dark. I travel alot so it goes into my briefcase and by morning its dead. I have turned off bluetooth devices, reset the SMC, have no external devices connected other than a thunderbolt monitor, booted into safe mode and followed every suggestion out there. Apple support person said he's never seen this before which is ridiculous because there are so many cases I have read about including Apple Support Communities. Does anyone have any experience with this?

Mac does not boot after installing bootcamp

hello
installed bootcamp on my mbp with snow leopard today,for the first time mac and windows both started with no problem ,but when i was trying to boot back into the mac again ,it did not boot and just got stuck at the process with turning wheel forever ,showing the apple logo and the turning wheel.
i did try to hold the option button and chose the mac partition ,but again i can not pass thru the turning wheel and apple logo.Does anybody know what the problem is and how can i go beyond this .
thanks.mike

Have you tried a safe mode boot yet?
Reboot to the OSX partition and hold the shift key down as soon as you hear the chime. You can release the shift when you see the spinning gear wheel.
yes,i did try that too.unfortunately ,hard drive seemed to be the source of the problem.just replaced the hard drive with a brand new one and put this one inside a usb enclosure that i have ,so tomorrow i will get a backup first and then format it again and keep it for the future.
thanks.mike

My mac is not sleeping!

Hey, I'm having a problem with my mac. It won't sleep automatically (by energy saver settings). I've deleted the iStat Dashboard Menu, quit LogMeIn, closed all apps.
Any ideas?

Here's my sleep tip......
This is for a Mac that won't sleep.
Here is Apple doc.#303698 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards. Also, here is Apple doc.#305262 about PCI cards and sleep.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Tristan Currier noticed this; "I have a Canon printer(shared) and my imac would not sleep. I opened up printer/fax in system prefs and noticed it said the printer was in use when it was off. Opened up the printer queue and noticed about 7 pending documents. Deleted them all and now it sleeps.
Check the printer queue!"
Good Luck!  DALE

New iMac shuts down but does not start as set in Energy Saver Schedule

Set Energy Saver schedule to shut down at 2300 and it does so at approx 2305. Set schedule to start up at 0700 and it does so the next day but NOT after that (have repeated the exercise 3 times - same result!).

You should not be having "Energy Saver" problems on a new iMac.
Have you tried any of the following?Restarting your computer?
Doing a PRAM zap?
Since you are still under warranty, strongly suggest that you take full advantage of it by calling Apple tech support. Especially if you are within 90 days of your warranty and/or have AppleCare.

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!!

Mac Pro does not sleep with lid open

Hi this was the original post I posted a couple days ago.
"Hi All,
I have had a problem with my mac book pro, it does not sleep while the screen is left open. The way I used to be able to tell if the mac is sleeping is the light on the front should flash as it does when the screen is closed. Here is what has happened in the past.
1. The original hard drive failed and was replaced with a 500gb
2. I have had the top case replaced as the mac book pro would not sleep with the screen closed
3. A clean install with OSX 10.6.8
After doing all this, the mac is still having the same issue.
When the screen is left open, I can hear the fans whirring away and the battery is drained as if I am running an intensive program. I can leave it all night with the screen up and wake up to the battery being completely dead. It usually takes about 3 hours or so. (105 cycles on the battery). The settings are set so that the screen and mac hibernate after 1 minute, and all applications are closed with wi-fi, etc turned off.
When my fathers and my brothers mac book pro is left open, the light on the front of the case flashes.
I have been to the apple store repeatedly and they are adament there is no issue with the mac. They did all their "tests" and the hardware was tested as "good".
Thanks for any help!
Chris"
The problem was solved with the following:
1. Deleting Login Items
2. Turning off blu-tooth
3. Unchecking "wake for network access"
Sources given:
http://support.apple.com/kb/TS3402
http://support.apple.com/kb/TS4167
However, the same problem came back last night.
Any ideas what is causing this?
Thanks,
Chris

I forgot to mention that I followed the same instructions that did solve the problem.
The things I tried were:
1. turning off wi-fi
2. closing all apps
Doing this however did not solve my problem either.

Energy saver settings do not stick when set in system preferences

For some reason when I restore the default settings for the energy saver settings, the settings go back to a custom setting I set months prior of Display Sleep at 1 minute.
Here is what I am doing:
Going to "System Preferences"
Going to "Energy Saver"
Pressing the button "Restore Defaults"
Everything goes back to the default settings of Computer Sleep of 10 minutes and Display Sleep of 10 minutes and I close the window out.
Problem happens: A bit later I come back to my iMac and wake it up, the setting is back to 1 minute of Display Sleep (which I did months ago, I no longer want that).
I have even locked the setting to prevent further changes. Which locks the settings in place like it should I believe. However, once the iMac sleeps and I wake it up in a couple of hours it switches back to the old setting I made months ago, 1 minute of Display Sleep, which I no longer want.
Thanks in advance for any assistance!

i have the opposite problem... i would like to use custom Energy Saver settings but they will not "stick." instead they keep returning to the default settings. i followed the advice on this thread, thinking it might solve my problem too. but it did not. any suggestions?
i had one hunch - that it might have something to do with the file of same name but with ~orig at the end (see image below). should i remove the other file as well?
thanks!

Mac does not save settings.

Hi, I'm new here (I haven't got my mac for a long time either), so please bear with me!
I have a problem with many programs, namely my mac does not save the settings.
Word: The change of default Czech language into Polish is not permanent. Czech comes back after the restart.
Ableton: The authorisation of the program is withdrawn when I switch the laptop. I have to authorise it again after every restart.
Cubase: It changes audio input and audio output back to internal speakers and microphone after the restart.
Additionally, for example, I have changed the preferences of video files. I have changed the default player from QuickTime to VLC. Restart undoes the changes.
Has anyone have a similar problem?
Thank you in advance for your reply.

Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.
Triple-click the following line on this page to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
 ▹ Restart
from the menu bar.

Solution for 'my mac will not reconnect after sleep'

After lots of trial and errors I found the way around the problem of dropped or very poor wireless connection after you put your mac to sleep.
I have no idea what the problem really is but this procedure has stopped me from throwing my brand new MacBook through the window.
1) Go to System Preferences -> Network -> Advanced
2) Remove any network you have there memorized
3) uncheck option 'Remember any network this computer has joined' (leave the other options also unchecked)
4) press ok and switch AirPort off ... then on (make sure you have 'Show AirPort status in menu bar' checked)
Now the only real change we've made is to stop Mac memorizing our network - but here lies the solution.
Put your MacBook to sleep and than wake it up. It will not connect to the network (none are memorized) but all you have to do is choose your network name from the list on the menu bar. It might ask you for the key but in my case it simply asks for permission to use my KeyChain (memorized WPA2 password).
Once I press 'Allow' .... it works as it should! eureka!
Do not check 'Remember this network' when asked for password.
As long as Mac does not store your network details it reconnects without problems, once you allow it to store these details, re-connection after sleep goes pear-shape.... figure it out Apple!
I hope this might help you (as it most certainly works for me)
best regards

I've run Keychain utility. I also removed (as suggested in various places) any entries referring to my wireless password in KeyChain and allowed them to be memorized again. It doesn't change a thing.
Please understand me correctly. My Airport does re-establish connection automatically (if network details are stored) but connection is extremely flaky, slow and with frequent dropouts. So the Keychain is not to blame here (I think).
If I establish connection 'semi-manually', as described in my previous post, it is perfect, just as it should be. This would indicate to me that the problem lies not with the Keychain, but in the way OS stores network details.
If I do not allow OS to keep network details - re-connection works.
