Display won't sleep after being in suspend once.

When rebooting the computer, the display sleeps after set interval and can manually be put to sleep using shift+ctrl+eject.
However if the computer goes to sleep or I myself close the lid to make it sleep, the display won't sleep again.
The display won't sleep after set interval in power settings and when I press shift+ctrl+eject the keyboard backlit turns off but the screen stays on.
The only way to make it sleep is to close the lid.
I have tried resetting SMC and NVRAM but to no avail.
I have the first generation aluminium macbook.
Does anyone else have this problem?
I have had this problem both in 10.6 and 10.8

Display won't sleep after upgrade to 10.4.4

I ran the update to 10.4.4 today and now my display will not sleep. Since then, I have:
1. Ran the fix permissions utility
2. Restarted, zapped p-ram
3. Deleted the preference file in /Library/Preferences that houses the energy saver configuration, then reconfigured.
Any other ideas? I did not change any of my settings after running the updater and this had been working fine since purchasing the computer.

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.
In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.
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 would be the 10.4.4 Combo update. Others reading, download the combo update that applies to you!
Cheers!

Display won't sleep and screen saver won't sart

I upgraded to the new OS and the display won't sleep and screen saver won't come on. Help please.

Long shot.
Do a backup.
Quit the application.
In Finder hold down the option/alt key while selecting the Go menu item. Select Library. Then go to Preferences/com.apple.systempreferences.plist. Move the .plist to your desktop.
Restart the computer, 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 ones.
If you want to make your user library permanently visible, run the below command in Applications/Utilities/Terminal.
chflags nohidden ~/Library/
You will need to do that after any updates.

Iphone 5 won't charge after being dead for three days.

Iphone 5 won't charge after being dead for three days due to power cable breaking. I got a new cable and it still will not charge. Is my phone broken in any way? What can I do to fix this?

Hey TalkBack12,
These are the recommended troubleshooting steps I found for when your battery does not charge:
Battery does not charge
Verify that the outlet being used is working.
Try another USB power adapter if available.
If no other USB power adapter is available, try connecting to a high-power USB 2.0 port (not a keyboard). The computer must be turned on and not in sleep or standby mode.
Try another USB cable if available.
via: iPhone and iPod touch: Charging the battery
http://support.apple.com/kb/HT1476
Since you got a new cable, I would concentrate on trying a cable other than the new one.
Welcome to Apple Support Communities!
Sincerely,
Delgadoh

my iphone won't beep after being located with 'find my iphone' app.

The phone "beeps" only if "Play Sound" is ON and after clicking "Send" (even if no message). Just locating the phone doesn't make it beep.

Dialog box display won't update after screen blank or being moved

I have a modeless dialog box used for status display by a plugin I wrote for Acrobat. Everything works fine until the screen blanks or the user moves the dialog box on the screen, at which point no further updates to the dialog box are displayed. My plugin consumes 100% of CPU for long periods of time so the program can appear dead without this display being updated, but nothing I have tried seems to make any difference. The dialog box is generated with ADM and things I have tried include calling "Update" on the dialog box at regular intervals, the windows "Sleep" function to yield the CPU periodically, and a host of similar tactics.
I'm guessing all the code will get run together once I click submit, but here is how I create the diaglog box (it was working fine without the "WinAppRegisterModelessDialog", but I saw a reference to it elsewhere and tried it to see if it would help, not sure if it actually serves any useful purpose):
statWin = sADMDialog->Create(inPluginRef, DIALOG_ID, IDB_DIALOG1, kADMModalDialogStyle, NULL, NULL, 0);
WinAppRegisterModelessDialog((HWND)sADMDialog->GetWindowRef(statWin));
infoBox = sADMDialog->CreateItem(statWin, 5, kADMTextStaticType, &coords, NULL, NULL, 0);
// Status header
coords.top = coords.bottom + 10;
coords.bottom = coords.top + 12;
statHeader = sADMDialog->CreateItem(statWin, kADMUniqueItemID, kADMTextStaticType, &coords, NULL, NULL, 0);
// Status line
coords.top = coords.bottom + 10;
coords.bottom = coords.top + 12;
statLine = sADMDialog->CreateItem(statWin, kADMUniqueItemID, kADMTextStaticType, &coords, NULL, NULL, 0);
// Progress bar
coords.top = coords.bottom + 10;
coords.bottom = coords.top + 15;
progress = sADMDialog->CreateItem(statWin, kADMUniqueItemID, kADMProgressBarType, &coords, NULL, NULL, 0);
sADMItem->SetMinIntValue(progress, 0);
sADMItem->SetMaxIntValue(progress, totalPages);
// Set window size, and other attributes
sADMDialog->Size(statWin, coords.right + BORDER, coords.bottom + BORDER);
sADMDialog->SetText(statWin, PROD_NAME " - Progress");
// Set header for status line
sADMItem->SetText(statHeader, " Page # % Complete Estimated Time remaining");
// Initialize progress bar
sADMItem->Update(progress);
Updates are currently performed with the following code segment. The last two lines are my attempts to get the display to update once the screen blanks:
// show it
sADMItem->SetText(statLine, textBuf);
// Update progress bar
sADMItem->SetIntValue(progress, pagesCompleted);
// Force display update/refresh
sADMDialog->Update(statWin);
// Yield for display update (in case of screen blank or user changes)
Sleep((DWORD)100);
Everything works fine until the window is moved or screen blanking occurs, after that nothing seems to work, all updates to the box cease to be displayed. Any suggestions?

OK guys here's an update. First I went to BIOS and updated the initial display setting to "LCD panel only" from "Auto". At first I thought it helped, because when I worked at the laptop without the external screen attached, the internal LCD panel resumed normally from off (previously this didn't work).
But today while I was in the office with my external 19" LCD screen attached, and both of them went off after being idle for 10 minutes, the internal LCD panel didn't resume again. So I've tried the Fn + F5 key combination to switch between modes, and I switched from dualview back to single. The internal LCD panel blinked for a second and then turned off immediately, and from that moment on, I was without picture on both of them. SO I ended up hibernating and resuming again. :( An important note - as soon as the computer began hibernating, the LCD went on and I could see the whole progress of hibernation before it turned off.
Also another note - when I'm in dualview, I always have keep the internal LCD panel as the primary screen. So unfortunately, when it doesn't resume, I don't have access to the taskbar etc to try more things...
Any more thoughts?
Thanks again!

On battery MBP won't go to sleep after being inactive for 5 minutes

Okay so in energy saver under system preferences, I have it setup so that the computer should go to sleep after 5 minutes of inactivity when running on battery power. However multiple times I have left teh computer on battery only to come back in a few hours and the MBP was still on and not sleeping. I had itunes and safari open, but itunes wasn't playing any music. What does it take for the computer to be "inactive". Do I have to close all of my applications?

I have had similar issues with this. Seems the:
Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
Gets corrupted and must be trashed, reboot reset PRAM and reset your power management settings.
I hope this helps.

Macbook Pro won't sleep after updating to 10.4.11

Hi,
I just updated to 10.4.11 reluctantly from 10.4.9 as whenever I do update I always have issues...I basically just went to software update last week and updated to everything I could. I've just been reading the forums and noted that updating is not always that easy...
Well basically my computer won't sleep if the lid is left open, this is IMMENSELY annoying since I often leave my desk to work on drawings, and I don't want energy being wasted like it is at the minute. Call me picky but I just want my computer to work.
I've reseted the PRAM, (option, alt, p and r), closed all applications, etc, but no luck...
Its a 2.2ghz MacBook pro, 2GB. Thank you in advance
Neal

The important thing for the future imho, is to always Repair Permissions before & after any update... seems to ward off most of these problems. Of course that is only good if the disk is Verified once in awhile.
Using Disk Utility in Mac OS X 10.4.3 or later to verify or repair disks...
http://docs.info.apple.com/article.html?artnum=302672
About Disk Utility's Repair Disk Permissions feature...
http://docs.info.apple.com/article.html?artnum=25751
In fact I'd start with those 2 now, if that doesn't help you may need to reapply some updates by getting them directly from apple>downloads.

When I'm on a Skype, Mac Air display won't sleep?

I often have a Skype call connected as my boyfriend and I are having a long distance. The display would sleep when I was having a call and out of the room when I was using OS X 10.6.8
but since I've changed to use mountain Lion 10.8.2, It won't sleep.......
I think its hurting my display for keeping a long time on.
What's the problem?

I've already unchecked "Wake for Wi-Fi Network Access" but its not working...
but the problem has just happened after I upgraded my OS...
I wont end it... because we r in different time zone so he would like to keep it connected when he's sleeping....

New iMac display won't sleep?

Hi, new iMac 24", 10.5.7, set screen saver at 5 minutes, and display to sleep at 10 minutes. Screen saver works, but it will not sleep. I've changed the setting, and rebooted, still no luck.
I tried everything from suggestions, with no help. I found that if I turn off "screen sharing" in system preferences, it will sleep the display for whatever minutes I set. I have to leave "screen sharing" on because I have flat screen tv hooked up to watch video files on, and I use iPhone app to control screen, to hit play and pause, etc. It is set up with a password, and only my iPhone is used when I am watching something. Why should screen sharing stop display from sleeping? I've left screen sharing on since I got this, so I can remotely log in with "back to my mac" from the road, and it never stopped the display from sleeping before? I shouldn't have to turn off screen sharing just to sleep the display? Am I missing something?

This is for a Mac that won't sleep.
Here is KB article HT1776 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 card.
Also, here is Apple KB article TA2469 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!"
Allan Jones says "sometimes there is Network activity: launch System Preferences > Energy Saver > "Options" tab and uncheck "Wake for Ethernet network administrator access."
Good Luck!  DALE

Windows 7 64 bit won't resume after being locked

Hello,
My Windows 7 Pro computer will not resume after being locked.
I use a Domain controller based on Windows server 2008 R2, and if I login with my username on any other PC, I do not have this Problem.
When I lock it to go out for some reason, it won't resume at all. I left it on the welcome screen for an hour or so, and it didn't start.
Do you guys have any idea what might be causing this ?
Thank you very much for your help

If this behavior is not exhibited on any other systems in your environment, I believe it's safe to assume the issue is with the local client.
First things first: check that you have the latest drivers for your system. I know this seems like a canned answer, but I've seen hundreds of cases where a missing or legacy disk controller driver causes all manner of strange behavior on an otherwise healthy
system.
Years ago, when SSDs first starting becoming popular, I purchased a handful of them from a specific vendor. We started seeing issues with resuming from S3 sleep that confounded us for months. We found out that the vendor used a specific brand and chipset
on their SSD controllers that wound up causing firmware faults when Windows was resumed; even to the point that we had to shut down the PC, unplug it, and let the caps drain before we could boot it again!
We wound up replacing the drives with a more mainstream/popular brand and the issues never happened again, but the problem was hardware related. Your post reminded me of those few months of confusion.
Check that all of your drivers are up to date, esp. disk and video, and don't rely on the Microsoft generic drivers. If you can find the drivers for your mobo/gfx cards, prefer that route.

External display won't sleep

I just purchased an NEC PA271 27" LCD display for my Mac Pro. It's beautiful, clear and sharp, but there's one problem: it won't sleep.
When I put the computer to sleep or shut it down, the monitor doesn't go into sleep mode. The blue LED on the front is supposed to turn amber, indicating sleep, but it doesn't.
I've tried resetting the SMC and PRAM, as well as repairing permissions, to no avail.
Any ideas?

I should also mention that I didn't have any problems with my ACD 23" previously, so it would seem to be an issue with this particular display and how it communicates with my Mac Pro.

Laptop display won't sleep

I just upgraded from 10.3.9 to 10.4.8, and I’m almost completely satisfied except for one last thing: I play a MMORPG that runs in full-screen mode, and when I was running 10.3.9, the display eventually became dim and shut down after several minutes in accordance with my preferences in Energy Saver. This is not happening in 10.4.8. What do I do? I jiggered my screensaver and display-sleep times, but this hasn’t worked. Thanks very much. Peace.
PS, how do I get file sizes to display when I do a search in the upper right-hand corner of a finder window like I used to?

I meant to say, there are times that one leaves the game running while one leaves the computer for hours at a time, and the display eventually dimmed and went to sleep while the game was running in full-screen mode. Anyway, the laptop display isn't sleeping since I upgraded to 10.4.8 from 10.3.9, so how should I set my preferences? Peace.

Macbook retina display won't sleep

Anyone else have this problem ? I don't know if its a macbook retina issue or mountain lion issue, just want to see how common it is. The screen won't turn off even after I set power preferences to turn off when idle for 2 min. When I try to force it to sleep from apple drop down menu, the screen turns black and freezes.

my laptop goes to sleep at night... fan stops making noise..
and I shut my laptop...
then I wake up and find my retina fan humming away and the computer is hot,
why is it running in it's sleep? when Im not using it??
i even have "put hard disk to sleep" after an hour...
why is it not??

Display won't sleep -- PreventUserIdleDisplaySleep bit set

Hi, my Mac had a problem such that the display, which is set to sleep after 3 minutes, would not go to sleep, wasting power and lighting up my office undesirably. I just wanted to post it as a possible helpe to others.
Last night, the PreventUserIdleDisplaySleep bit got set by something called "powerd" and something I hadn't seen, NoDisplaySleepAssertion, got set by "screensharingd".

My solution was to turn off ScreenSharing, then go to the Terminal and do this:

Simply killing the offending processes didn't work, I had to explicitly turn off Screensharing first.
I then checked and PreventUserIdleDisplaySleep was 0:
