Cinema Display Sleep Won't Wake on Mouse Move

After the Cinema display sleeps (MBP is still awake), prior to Lion, I would just move the mouse and the display would wake. With Lion, moving the mouse has no effect, and I have to open the MBP to wake the Cinema display.
I use an external monitor, keyboard, and wireless mouse.

I am having the same problem on my MacPro after upgrading to Lion. I had this problem with Leopard originally, and the solution involved resetting the SMC and resetting PRAM. However, those tricks did not work with Lion. Once the display goes to sleep, it will not wake up. The computer itself is fine (configured to never sleep). I can ssh into for example. I note that an attempt to reboot with "sudo shutdown -r now" fails to reboot successfully however and I end up having to powercycle in order to recover my displays. For now, I'm just going to set my "Display sleep" Energy Saver preference to Never to avoid the issue.
For my MacPro: resetting SMC involves:
a) unplug power for 15 seconds
b) plug in power and wait 15 seconds
c) boot
For my MacPro, resetting PRAM involves:
a) When turning on power, hold down command, option, P, and R keys. wait for 2nd beep to indicate PRAM is reset, then release keys

Cinema display does not always wake with MacBookPro Retina

I have a MBP Retina display and often use Apple 23" Cinema Display, with the rMBP closed, not running both displays. Sometimes the display is slow to come on, but will with a bit of prompting through hitting the esc key (USB keyboard) or my blue tooth Apple trackpad. Occasionally, nothing works. I open the rMBP and it wakes up immediately, close it, try the prompts with the display and nothing. Then I have to restart the rMBP.
I do not have an issue of the rMBP not waking as many others have posted. However, mine is sometimes slow to respond when it appears to be awake.
I did not have any issues with the cinema display with my old MBP (early'08). The display worked well and always came right on.
I am running ML 10.8.2.
Any suggestions?
Thanks.
Larry

I have not tried this but would this be on any value, as there is quoted from the site:
"For example, if you wake a laptop up from sleep sometimes, and your network has changed, lookupd is the little ******* that usually makes your laptop just not wake up."

IMac 2011 screen unexpectedly goes black (to sleep), won't wake

I've been having an intermittent problem. I'm using an iMac (late 2011) with 10.7.3. I'm doing things on the computer or some process is going on when the screen instantly goes black (no dimming first). If a video was playing, I can still hear it playing, but pushing keys on the keyboard or mouse or pad does nothing to wake the screen. Sometimes pushing the power button a number of times will get the screen to come on, sometimes it won't. When the screen goes black, if an external drive was running and then stops, I can sometimes get the screen to come to live. Sometimes this black screen happens when I'm burning a DVD; when the DVD is finished, I can bring the screen to life. I thought one of my two external drives was bad, so I disconnected it. That seemed to help (though verifying the disk revealed no problems). But a few minutes ago, the screen instantly went black again; no dimming first. There have been times I thought this was associated with a new bit of software, but then it returns even after I delete the suspect software. Sometimes I have to use the power button to shut down the iMac then restart it. Once, I had to unplug and replug the iMac before I could get the computer to respond and the screen to return to life. I don't know if this is a hardware problem (internal or external), a software problem, or some combination...or something I haven't thought of, at all. Very annoying. Verified the internal drive, repaired permissions; no problems noted there.

Exactly the same issue here - same machine and OS. got so bad now that it blacks almost as soon as it comes on. Over the past few weeks I also experienced the flickering screen that others have complained about. The black screen only occured after installing latest update (7.3) - and I only installed this after earlier problems with the update reported by many users were sorted - but the flickering happened before so may be not relevant.
What's happening when you press the power button a couple of times is probably that you have 'use power button to put computer to sleep' selected in System Prefs. Henmce, 1 push puts it to sleep and 2nd wakes it up.
I have done all the usual checks plus power down, unplugged for 20 seconds and then restarted to reset the SMC (System Managemenmt Controller) but problem has recurred - normally after sleep.
Aplle did have a large batch of faulty LG screens apparently so maybe this is the poblem. Otherwise maybe graphics card issue,
Mine's off to a service centre tomorrow whilst it's still under warranty... will update when I get it back

Put to Sleep - Won't Wake Up!

The last two times I put the iMac to sleep, it would not start up the next morning. As per Apple's instructions, I removed the back cover and was able to re-start using the internal power supply button. After the second time, I just stopped putting it to sleep and it has been fine. But obviously I'd like to know what the problem is. My computer is one of the models covered by the extended warranty for faulty logic boards. Is this definitely the problem or could it be something else - and is there any way to find out on my own? Thanks!

Here's something you could try;
If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following line:
reset-nvram
press the return key on your keyboard
set-defaults
press return
reset-all
press return
Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
Still did'nt work? Might be time to call AppleCare or see an Apple Genius or a technician.
Cheers!

PowerBook Problem Won't wake up, mouse doesn't work etc...

Hello all, thanks for taking the time to check my post.
I have a friend here who's g4 powerbook, when it goes to sleep sometimes it won't wake up. Sometimes the mouse won't work after it wakes up. Are these signs of something that can be fixed by the user or should this machine be serviced?
Thanks in advance ;)!

Hi, Greg Willmott
i have not experienced this kind of problem myself. I would think it has to do with some settings which clash.
I would do:
a) search the forum with the extended search possibilities;
b) reset PRAM (Restart the computer holding down the 4 keys "option-contr-P-R" at the moment of the 1st chime, and keeping them pressed until a second chime)
c) check whether the problem happens if you put the PB to sleep while no application is running - if it happens only if it sleeps while applications are running, it might hint to these, especially their preference settings);
d) check the hardware memory (use disk-utility);
e) repair permissions (with disk-utility as well).
if all this doesn't point to a cause, i would try to reinstall the software from scratch. sorry - this take some time... for this, I would keep the following order:
1) BACK UP EVERYTHING you want to keep;
2) do an "Archive and Install"
3) check whether things are now fine.
if the problem persists, do
4) "ERASE and INSTALL" - performs a complete clean
installation, no old software remains.
if the problem now still persists, I would be inclined
to think that it is hardware, and that Apple has to be
approached;
if the problem has disappeard now, I think it points
at the settings of some applications (or hardware
such as external disk or mouse or...) . The
5) install the different applications one by one and try
after each one - if it shows the system, you might
have found the one which is incompatible with the
others...
sorry, might be a long search- but give it a try.
PLease, post back, Thomas

Cinema DIsplay sleeps when I use Boot Camp with Radeon 5870 through DVI connection

I just created a bootcamp partition on my Mac Pro (1,1) with Radeon 5870 and XP Professional so I can play Train Simulator 2012 with maxed out settings. Well after hours of installing Windows XP and updating it (via Parallels so I could do other things while waiitng for Windows) I got Train Simulator 2012 installed, Windows XP Professional fully upto date and reboot to bootcamp. I see the Windows screen and then my monitor goes to sleep (best guess). I am using an Apple Cinema Display 20" and is of course connected to the DVI port. One guess (and I hope I am totally wrong about this) is I think I remember reading the DVI port id display 3 not 1. I hope this isn't the problem (requiring me to buy a $40 Mini Display port for DVI adapter.
Any ideas as to why this is happening? I was so looking forward to playing Train Simulator with maxed out graphics via Boot Camp with the Radeon 5870 1GB. Don't get me started as to why my line out is not being detected by XP Pro.
I also have the latest Bootcamp drivers for XP (3.2).

Never used XP and on Mac Pro I wanted to use all 4-cores and more than 1.9GB RAM but often it seems that in the past and with Fusion anyway you would need to install Windows updates and drivers natively not thru or in the VM.

External Monitor in Target Display Mode Won't Wake Up

I'm using 2 imac 27' and one is simply used as an external display. When I wake up the computer from sleep, it works on the main monitor, however the external display still has a black screen. I have to unplug the external monitor to get it to wake up. Is there anyway to fix this? I tried unplugging thunderbolt and replugging it in which worked the first time, but same issue again not waking up.

Same issue here, I'm using a macbook pro retina and connecting to a 27 inch imac via thunderbolt and target display mode.
I also have a 27 inch thunderbolt display hooked up via tbolt cable as well.
Whenever the displays goto sleep, the iMac does not wake up with the other screens. My setup knows the iMac is part of the displays, it doesn't act like there are only 2 screens available.
If I press the target display mode shortcut (command + f2) then the imac screen turns on, but now its left target display mode (so it clearly is in target display mode, but does not receive the command to turn on display or ignores it). Hitting hte shortcut again now switches back.
I have not tried just the mbpr + imac as target display mode, but based on your post it still wouldn't wake up if it was the only machine connected.
I've found that when I come back to my computer, i just hit command +f2 on the imac, which wakes it up and jumps to its screen, t hen i hit command +f2 again, and now I wake the mbpr from sleep so it doesn't have to go from 2 screens to 3 screens.

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.

Prevent Macbook/Cinema display sleep mode when switching from plugged-in/off

Hello, I've a macbook connected to a Cinema Display. On Energy Saver, all is set to never go to sleep. I'm trying to prevent my macbook going to sleep mode when I plugged off it. Do you have any solution for this?

KinoBillie wrote:
Hi tjk,
Yes I mean when I disconnect the power supply (that comes from the Cinema Display) the macbook pro goes into sleep mode until i press a button on the keyboard, then it returns into running mode (even if in energy saver all is set to never go to sleep).
I would like that, if there is a power cut in my house, the mbp does not go into sleep mode but continue to be in execution (by means of battery) avoiding sleep mode.
Thanks
Looks like someone already cut in to try answering, but I'll answer the question you asked me anyway. You can read Apple's directions http://support.apple.com/kb/HT3131 and see that unplugging is the cause. It's not really an issue, it's just the way it works.
Contrary to the statement "There's no way around it." you may want to look into UPS (uninterrupted power supply) if it's important enough to you. I have never used one so I am not familiar with them, but by their very nature/purpose, I would think they'd do what you need.

Sleep - won't wake up, and now randomly goes off to sleep

Since the recent security update, my 1.67 G4 Powerbook has been experiencing problems with sleep. Sometimes it won't wake from sleep, forcing me to hard reboot or pull all power out, and now it's randomly falling into sleep when it shouldn't.
The issue is progressive - it will sleep, then I wake it, then it goes down again 2-3 minutes later, wake, then seconds, wake, then deep somnambulistic slumber.
I read in Macintouch that there was a fix recently for Intel MacBooks and sleep, but some of us in the PPC world are feeling it's effect.
I've reset the pram several times, and on one occasion the fan spun up very loudly on boot, then quieted down after 5 seconds. Might be nothing.
Another factor is the battery - pull the battery and the system behaves better. I wonder if there's a lowered thermal limit that, when the battery is charging, causes the system to shut to sleep...?
Anyone else having this problem? I'm ready to slip back to 10.4.9 to see if that makes it more stable -- this happens several time a day now.

For other who may be watching this...
The laptop did keep shutting down into sleep, but - following from a tip from another site - I began trying three things: One or all seem to have resolved the issue:
* Repair permissions - often and always. Something does get munged and I'd be interested to see if anyone else has the same files affected:

* I stopped zapping the PRAM when it went to sleep or wouldn't stay awake on boot - I just booted from DVD instead and, lo and behold, the thermal errors didn't occur under the DVD. Fixed permissions and a reboot it often worked fine for hours.
* Running it alternatively from either battery or from mains. Initially under the battery, it would sleep at 70-60%, then - after a few days of being shut down instead of slept - it began running down to 0. I'd have to plug the unit in and charge it whilst off, but now -- after a week of this - everythings back to normal.
Ultimately, I'm sure this software. Something is up - and slowly, if you're patient, you can bring your system back without buying a new case or motherboard.

MBP goes to sleep, won't wake up!?!?

Recently my MacBook Pro has began going to sleep, either after not being used or after I shut it, and then it won't wake up and has to be restarted manually, which costs me data, time, etc.
I've researched the problem, but haven't seen anything that sounded exactly like what I am going through.
Plus I'm not the best at fixing stuff myself (lets just say I'm not going to get hired as a MacGenius anytime soon).
Help me! I'm writing my National Board Papers right now and need my machine to be reliable!!!
Thanks in advance.

I have just started having the same problem. I used to be able to use the MBP for a few minutes, leave it on the table and let it go to sleep. Come back anytime and it would wake. Now it won't, and I have to go back and plug it in to get it to wake. I have just now noticed that the battery is almost drained. I used to be able to do this for a couple of days without charging, and now it won't make it 12 hours.
The battery being almost drained would explain the no wake, but now the question is why it is draining so quickly even in sleep mode. Especially when I used to tell everyone how great the MBP is, and how long the battery lasts and how quick is starts up. Of course I was telling this to all my co-workers where we are stuck with the company issued Dell.
I think this may have all started after upgrading to 10.5 or iLife08, as those are the only two programs that have recently been added.

Mac air goes into sleep won't wake

MacBook Air goes to sleep as normal, but won't wake up now.

A new mini is on the way & I'm researching UPS's. A question that I now have is -
The new mini will have 10.5 which will be nice, but I really want to put my old hard drive straight into the new unit so I can have my old computer back the way I like it. Right now I have my external drive with everything on it plugged into my wifes macbook, & I can access everything except my email. The old emails are there in the folders, but as numbered icons, & I can't find anything. With my business I often have to refer back to old emails, & right now it's really hard to. I have tried to import them into mail, but it says it doesn't recognize them.
If I do this, can I put the new backup discs in & load leopard onto the old hard drive without loosing my old information & setup? We are on a very slow dial-up here, so I've never been able to accept the automatic updates. I look forward your advice.

Won't sleep, won't wake

I'm having two problems with sleep mode:
WON'T SLEEP
my iMac G5 won't sleep even though sleep mode is activated in Energy Save preference pane (file sharing off).
WON'T WAKE
When I put my machine to sleep at night (sleep item under apple menu), it won't wake up in the morning. The blinking sleep light indicates my iMac is in sleep mode. I hit a key to wake it. The sleep light turns off. Nothing else: no noise, no screen but the black on. I wait a few minutes and press the power button: nothing happens. Once it starts up after a hard boot (power button, 5 secons). Most of the time I have to wait an hour or two and then I can start up my machine by pushing the power button.
This problem occured yesterday for the first time. Today I did many test with same results: no wake after "manual" sleep mode and no "automatic" sleep.
Note: Apple Hardware Test did not detected any problem.

Even though the hardware test did not indicate a problem, you may still have one. I'd give AppleCare a call. Also note, if you are out of the one year or AppleCare coverage, you may still qualify for this program:

Cinema Display 24" won't work with Mac Mini 3.1

I recently purchased a refurbished Apple LED Cinema Display 24" from a buddy. I'm pairing it with my used Mac Mini 3.1 (2009?). The display port mini connections seem to match. The USB is plugged in. The only cable unused is the "macbook power" plug, from the display. I know the display and CPU both work fine independently. Cinema display seems to power the USB and "Macbook power". I just can't get any life out of the display. These 2 devices should work together right? Is there a sceret power-button that I don't know about?

The video cards that ship with the current Pro have one Display Port and one mini DVI port.
There is an adapter to connect a DVI monitor to a Display Port connection. There is no such thing as an adaptor that will let you connect a Display Port equipped monitor to a mini DVI port on the graphics card.
Final Cut Pro uses dual monitors connected to the same graphics card. Using a twin graphics card setup causes problems with FX Plug FCP plugins, which can cause FCP to fail to launch.
The solution is to find a Graphics card with dual Display Port connectors, (if one even exists) or replace it with a grahics card that uses dual DVI ports, such as the ATI 3870 HD. Of course, the latter means that you cannot connect two 24" Apple Cinema Displays.

Old Cinema Display 22" won't work with DVI-ADC adapter & Mac Pro

So, I want to use my old 22" ADC Cinema Display with my new Mac Pro with the Radeon x1900 card.
And I was told to buy the DVI to ADC adapter, which I did.
But it doesn't work! The adapter powers up my monitor, and it shows up in the Display settings of system prefs, but the monitor remains DARK.
Anyone hear of this happening? I spent an hour with Apple Care phone support. They have no idea what to do.
Is the 22" (model #M8149) just not compatible with this adapter? I'd hate to have to buy a whole new monitor!

Yes, I tried re-setting the PRAM as well. Didn't work.
I've gone into the Monitor display settings and clicked "Detect Displays"...I've changed the Hz on the VGA monitor that I have plugged in simultaneously (a Gateway FPD1510). Not working.
As I mentioned, the computer does detect the monitor...it shows up in the Display Arrangement window and I can change its resolution, etc.
And the power light is on.
It's just that the screen in black.
Is this monitor just incompatible with this adapter?
Sounds like someone else is having this issue too, right?
