Display does not go to sleep

I have two Macbooks, early model (2006) and later model (2007). I've set the display to go to sleep while on Power Adapter on each model using Energy Saver preferences. It's not happening on my 2007 model - never goes to sleep no matter how long I set it for. Each machine is running MacOS 10.5.6 and each has System Preferences version 5.2. Another question is that the GUI is different for Energy Saver preferences. One shows Battery and Power Adapter at the top (2007), and the 2006 model has a pull down menu with Power Adapter, Battery, and Custom. Why are these different if OS and System Preferences are the same.

Hello Spence
Reset the SMC (System Management Controller might help.
http://docs.info.apple.com/article.html?artnum=303446-en
From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
Unplug all cables from the computer, including the power cord and any display cables.
Wait at least 15 seconds.
Plug the power cord back in, making sure the power button is not being pressed at the time. Then reconnect your keyboard and mouse to the computer.
Press the power button on the back to start up your computer.

Mac Pro display does not recover from sleep

Hello,
I have a Mac Pro Mid 2010 with two graphics cards (ATI 5770 & nVidia Geoforce GT 120) and three displays. After intense use of the GPUs with graphics processing jobs, and after the screen goers to sleep, they do not recover. The computer is accessible via the network (ping, ssh, etc) however, the screens blank out and no longer recover from sleep. The only resolution is to reboot.
I have already run memtest all just to make sure there isn't a memory issue. All tests passed. Also, this issue has ocurred with Mountain Lion and Mavericks.
Does anyone have any suggestions or experiences with regard to this iussue?
Thanks

Update -- I now can reproduce the issue at will and it is definitely related to the sleep feature and has gotten much worse under OS X Mavericks. Side Rant -- First let me note how disappointing Mavericks is as a platform. Apple's output seems to be getting progressively less thought out, reliable and buggy.
Now back to the issue. I created a hot corner that puts my display to sleep. Every time I active the hot corner the system display is lost -- that is the system continues to function and respond via network (ping, ssh, etc) but no joy on un-sleeping the displays.
I have Mac Pro Mid 2010 w/ 2x 2.4Ghz Quad Core, 32GB RAM, ATI 5770 and NVidia Geoforce GT 120 using three displays (2x 27" Apple and 1x Panasonic 1080P HD TV) running OS X 10.9.1 (13B42).

External display on late 2012 macmini does not go to sleep.

External display on late 2012 macmini does not go to sleep, instead the content freezes. After Pram reset it does go to sleep, till it undergoes next system sleep cycle (hibernatemode 25). I need to suspend it to disk because it is an offgrid setup and the power needs to be cut between Sessions. Display is connected to the hdmi port. Runing OS 10.8.4. Reinstalling did not help, neither. I have struggled with this for half a year now, it accured about 2 month after first use of the machine.
Thank you for possible help!

Next on my list would be an installation from scracht - wich i would obviously love to avoid
The bewildering thing is that through a pram reset i can get the display to sleep once again...
Maybe a hardware prob?
Might want to check using the thunderbolt port instead, as soon as i can afford the adaptor.
Anyway i will go to offline world for some time now, on a crazy bicycle tour trough remote eastern europe.
I would love to hear from you on an occasion of a peek to cyberworld during my trip!
So long

TS4080 apple thunderbolt display image on display intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys. Rebooting by pressing the power button resolves issue.

My apple thunderbolt display (which I purchased 1.5 years ago; OS 10.7.5 Mac Mini) intermittently goes dark, does not wake from sleep after clicking mouse or keyboard, but there is "bonk" sound after clicking mouse or pressing keys, so am thinking it is a hardware problem with the display. Rebooting by pressing the power button turns the screen back on, but the same phenomenon has occurred several times. Could this be a software issue, or do I need to have my display repaired? Your feedback would be appreciated.

Hi ED, tough to tell, but it does sound like it's waking with the bonk, just not displaying.
Long shot but...
I wonder if it's a variation of this, of which I've seen many different symptoms...
Resolution
Move the mouse or trackpad cursor over the center area of the login window so you can see the user icons. Click on the icon of the user that you would like to login as, type in the user's password, and press Return.
If the login window is configured to show only the name and password fields, type in the user's name and password into the fields, and press Return (even if you cannot see the rest of the login window).
Additional Information
This issue will not occur if the display is not sleeping when the account is logged out. Use the steps below to confirm that the account is not configured to log out automatically while the display is sleeping:
1. Open System Preferences > Security & Privacy > General. Click the padlock to unlock the preference pane and enter your admin password. Click the Advanced button at the bottom, then see if the option "Log out after N minutes of inactivity" (where N is the number of minutes) is enabled.
2. Open System Preferences > Energy Saver and configure Display Sleep to occur after the account is logged out, by dragging the slider to a number of minutes that is greater than N was set to in the previous step.
Important: If automatic log out is not needed, disable "Log out after Nminutes of inactivity" in System Preferences > Security & Privacy > General. This will also prevent the issue.

2013 Mac Pro DisplayPort Monitor does not wake from Sleep.

On my 2013 MP I have dual monitors:
One connected DVI-to-MiniDisplayPort a ViewSonic 24"
Second connected DisplayPort-to-MiniDisplayPort a MonoPrice 27" 2560x1440
When the computer comes out of Sleep or Off the 27" display does not come out of Sleep Mode.
If I unplug and replug the MiniDisplayPort connection from the MP the Display will turn on correctly.
Never had this issue with the 24" both monitors go into a sleep/hibernate mode(yellow power light on displays) when the computer turns off or goes to sleep.
When the computer comes out of sleep the 27" backlight turns on briefly but then goes back into sleep mode.
Troubleshooting: PRAM Reset and alternative ports on the MacPro with no luck.
Any thoughts??
Thanks in advance.

MacBook does not go to sleep lid is closed

My new MacBook does not go to sleep when I close the lid. I have to manually tell it to sleep before closing the lid.

I'm having the same problem too. I only noticed it recently!
I have Parallels VM installed, but not BootCamp, but just incase I restarted the Mac then with nothing running tried closing the lid but MacBook stays on. I've checked the Energy Saver settings, usual put computer to sleep after 1.5 hrs and put the display to sleep after 15 mins, but that shouldn't make any difference when I close the lid.
I don't have an external monitor, and i unplugged by USB mouse too.
Another thing I noticed yesterday is that even after leaving the MacBook idle for 1 hour, my screen had not dimmed, and Skype had not gone to 'Away' even though it is set to goto 'Away' after 5 mins. It's as if there was something using the computer? I dunno!
And Ideas?
And if I DO tell it to goto sleep before I close the lid, when open it again, I need to hit 'anykey' wake it!
MacBook 2Ghz 1GB RAM Mac OS X (10.4.6)

Macbook does not wake from sleep properly.

My macbook 2.0ghz core duo, 10.5.6 does not wake form sleep like it should. it behaves similar to when it runs out of battery with a pale screen and a loading bar, like it is restoring the system from the sleep image, although the battery is full. Has anyone else had this problem and been able to sort it out? Perhaps there is something wrong with the battery controller. Any advice appreciated as it is quite annoying.

I am having this same problem. The computer itself is awake, but the display stays blank. I can restart it by pressing the power button then 'R' then 'return'. This just starting happening frequently recently for me. It may be the result of one of the more recent security updates.

Macbook pro does not go to sleep when closing lid

Hi,
I'm having a weird problem with my macbook pro. When I close the lid, my macbook does not go to sleep. Even more weird: when I put my macbook to sleep using cmd + alt + the eject button or using the apple button => sleep, my macbook stops sleeping as soon as I close the lid
It seems like this problem occured after installing the Nosleep extension for mac (http://code.google.com/p/macosx-nosleep-extension/). I already deleted that program and rebooted, but that did not help.

Please read this whole message before doing anything.
I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
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.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click anywhere in the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Qosmio X500-014 PQX33C-01400N display does not wake on reboot

Recently my Qosmio X500-014 PQX33C-01400N display does not wake on reboot. I can see the the HDD status light working but I don't see the BIOS boot process or the Windows login. It's just blank. I know it boots Windows as I hear the chime and the webcam lights up waiting for face recognition.
I can reboot and plug in an external display and see the whole boot process and it works, but when I log in, Windows does not detect the laptop display.
For the laptop display to work. I reboot and wait until I see the webcam lightup which I assume means Windows is already in login prompt. I close the built in LCD display down and wait for the laptop to go to sleep mode. Once in sleep mode, I prop up the screen and it awakes like normal. I now don't shut down my laptop because of this. I just close down the screen and put it on sleep so I can easily get to it by simply waking it up.
Is this a hardware problem? BIOS problem? display adapter problem? I've never seen this problem in any forum.
Any advice would help. Thanks!

As that's a Canadian model, you'll want to check their support site.
I'm not a tech support agent, but I doubt it's a driver issue because it's manifesting pre-Windows. Try checking for any relevant BIOS settings.

Installed Premiere Pro CS4 but video display does not work?

I just got my copy of CS$. After installing Premiere I found two things that seem very wrong:
1) video display does not work, not even the little playback viewer next to improted film clips located on the project / sequence window. Audio works fine.
2) the UI is way too slow for my big beefy system.
My pc is a dual boot Vista-32 and XP system with 4GB of memory installed and nvidia geforce 280 graphics board with plenty of GPU power. The CS4 is installed on the Vista-32 partition. My windows XP partition on the same PC with Premiere CS2 works great and real fast.
Any ideas how to solve this CS4 install issue?
Ron

I would like to thank Dan, Hunt, and Haram:
The problem is now very clear to me. The problem only shows up with video footage imported into PP CS4 encoded with "MS Video 1" codec. So this seems to be a bug. The codec is very clearly called out and supported within various menues but video with this codec just will not play in any monitor or preview window. In addition the entire product looks horrible with respect to performance while PP CS4 trys its best to play the video. Audio will start playing after about 30 seconds. And once in awhile part of video shows up at the wrong magnification before blanking out again.
My suggestion to the Adobe team: fix the bug and add some sample footage to the next release so new installations can test their systems with known footage.

Satellite P845t-10G does not go to sleep closing lid after Win 8.1 upgrade

Hi,
I own a P845t-10g and since I upgraded to Win 8.1 the laptop does not go to sleep (or shut down) when closing the lid.
However, when opening the lid, it wakes from sleep mode.
I tried installing latest Toshiba systems settings utility and all updates on the support site.
Any ideas how to fix this?
Thanks!

Did you check the option called: What closing the lid does?
Click on the 'Power Options' icon in taskbar (or in control panel).
Then click 'More power options'. Now a new windows will open. On the left side panel click on 'What closing the lid does'.
Now you will see two possible mode: battery and plugged in. For each mode you can set the action for closing the lid.
BUT one question: did you upgrade the Win 8.1 following the instruction from Toshiba?
http://www.toshiba.eu/innovation/generic/windows8_1-message/ Did you install all the Toshiba Windows 8.1 drivers and utilities in the right order!?

Mac Mini + A1038 Cinema Display does not work

Hi,
I have a 2009 model Mac Mini with mini-dvi and mini-display port's on the rear. I can connect any of my DVI based monitors to the mac mini using either the mini-dvi to dvi cable or the mini-displayport to dvi cable. All monitors except for the A1038 model Apple Cinema Display.
The cinema display works with 3 other computers with DVI ports, turns right on and is detected right away. When plugged into the mini it does nothing. Sometimes I can get it to work with the mini-dvi to dvi adapter but that is sporadic.
This is the same behavior with a 2009 model mac book pro and macbook. Using the mini-displayport to dvi cable the cinema display does not work but 3 other monitors do.
So my question is, why does apple hardware only work with non-apple hardware?

Is the A1038 the old, plastic Cinema Display that doesn't have a power cord or power supply? It only has a video cable with the special ADC on it? If that's the case, it needs this to run from a newer Mac:

Windows 8.1 does not go to sleep reliably anymore

I recently did a clean install of Windows 8.1 Pro x64 (final version). Before doing the clean install, all hardware being identical, my Windows 8 was ran smoothly and went to sleep fine automatically after the set time.
Now, after the clean install, although I believe I have installed and set up everything as before, the computer does not reach standby automatically anymore most of the time. To be precise, when I reboot or log off and on the PC, the sleep functionality
is re-established for a while, but after 1 or 2 hours of work it invariably gets lost.
However, as soon as I disable the Ethernet adapter, the PC sleeps as expected.
I do not seem to be able to figure out why this is, or how my configuration is different than before.
Here are a few specs about my hardware: ASRock Z77E-ITX mainboard (http://www.asrock.com/mb/Intel/Z77E-ITX/, has the Windows 8.1 compatibility sticker), Intel Core i7-3770, 4x 3.40GHz including Intel HD 4000 integrated graphics (no external graphics installed),
Intel 530 Series SSD, Intel 520 Series SSD, WD HDD. I have use a wired Ethernet connection, my Ethernet chip is from Broadcom. Wifi chip is disabled.
Since this has been a pervasive issue with all Windows versions, the internet is full of suggestions how to resolve this matter. Why I am not convinced that the old advice still has any bearing as I tend to think Windows 8.1 introduced new issues (bugs?),
for the sake of covering all bases, I tried almost every tip I could find on the net and will list my fruitless attempts in the following. It might also be useful as reference for other people trying to tackle such issues.
1) Installed latest Windows 8.1 drivers from Asrock's homepage. I also tried chip manufacturer's like Intel's own drivers, did not make any difference (so far).
2) Left the homegroup and disabled homegroup functionality as for example in these threads it has been argued that this is a new issue with Windows 8.1: http://www.eightforums.com/general-support/28226-windows-8-1-refuses-sleep-2.html
http://www.eightforums.com/general-support/33221-windows-8-1-does-not-go-sleep-standby-automatically.html
3) In the Ethernet adapter's settings, I unchecked ipv6. I also made sure the device cannot be awaken through the network.
4) I even went so far to disable network discovery as
file and printer sharing (both in private and public profiles) and disable
public folders.
5) Even though sharing is disabled, I also made sure that within the energy options the computer is
allowed to sleep when sharing media.
6) powercfg /requests returns "none".
7) ran powercfg /energy duration 300 from an elevated command prompt while the ethernet adapter was enabled. It found 9 errors, mostly related to USB hubs, but the same errors were also recorded when I repeated the exercise having the ethernet
adapter disabled. So these errors are probably not relevant for the problem at hand.
8) powercfg /devicequery wake_armed : just the mouse and keyboard appear
9) I tried netstat which shows many connections but do not know how to interpret them or what to look for. Same for
Wireshark. If anybody can guide me on how to use these tools, I am happy to learn about it.
10) powercfg -requestsoverride DRIVER \FileSystem\srvnet SYSTEM
did not help, reverted it.
11) Uninstalled software some would find suspicious: Cisco Anyconnect VPN Client, Shadowprotect Desktop backup software, VMware player. Did not help.
12) I also have a MySQL server installed, which I did NOT uninstall because it would be too much point reinstalling and reconfiguring it. However, I doubt this is the culprit as with Windows 8 it did not prevent any sleep. Even when I stop the server the
PC does not go to sleep.
This is more or less it. I am out of ideas and welcome any feedback.
Again, when the Ethernet adapter is disabled, the PC sleeps as programmed, but I cannot figure out what communication is responsible for keeping it awake.
Thanks,
Steve

Hi Steve,
I don't know if you'll feel better but - You are not alone facing the same problems, I am sure that all the power handling in 8.1 is a mess. If I force the comp. to go to sleep mode, after a while it is
not staying in the sleep mode but shutting down autonomously. I suppose there is more hidden bugs.

Isn't your computer just switching from sleep mode to hibernation mode after the amount of time set in your power management settings? This sounds like it, as in hibernation the computer is effectively shut off. This is also intended behaviour.
As you guys, I hope MS releases a fix soon.

My computer has been acting weird lately. Shuts itself off, the mouse goes off in all angles, does not go into sleep mode sometimes and instead shows on a gray screen definitions of words in 3" letters! Do I have a virus?

Doesn't really sound like a virus.
See if the Disk is issuing any S.M.A.R.T errors in Disk Utility...

How many of these you can answer...
Open Activity Monitor in Applications>Utilities, select All Processes & sort on CPU%, any indications there?
How much RAM & free space do you have also, click on the Memory & Disk Usage Tabs.
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
In the Memory tab, are there a lot of Pageouts?

MacBook Pro does not go to sleep when power cord is connected

Hi Experts,
I have recently discovered that my MacBook Pro (2009) with OSX Lion does not go to sleep when the power cord is connected. It does not matter if I close the lid or select sleep from the Apple menu. All that happens is that the screen is powered off, the SIL is solid and I can hear the HDD/fan. I have not changed any of my power settings recently and it has not been a problem previously. If I disconnect the power cord the MB goes to sleep as supposed to (the SIL led starts flashing).
Doing some research I have found other users with somewhat the same issues when VMWare Fusion is installed. I have done some further testing and it seems that if I disable the virtual machine's Network Adapter and quit VMWare Fusion the MB goes into sleeping mode when the lid is closed even with the power cord connected. Enabling the Network Adapter again prevents the MB to go into sleeping mode when the power cord is connected. This even applies when the VMWare application is shutted down.
My guess is that the Network Adapter somehow prevents the MB to go into sleeping mode. The workaround is of course toggling the Network Adapter on and off but the virtual machine has to be running in order to do so. Not being that familiar with network settings on a Mac is there any other way to get around the problem?
Thanks in advance :-)

To anyone,
I have turned internet sharing off but the Ethernet box remains checked. If I uncheck the Ethernet box, the Internet Sharing bubble turns red, however when I close System Preferences and re-open, the box is automatically checked although Internet Sharing is off. Because of this my Macbook Pro will not sleep properly.
All other sharing items are turned off. Only Internet Sharing continues to automatically show Ethernet as active from a Wi-Fi connection.
Any advice?
