Sleeping Problem With ACD 27"

I have a sleeping problem with my 27" ACD that is connected to a 2010 Mac Pro and a Macbook Pro. The display is set to sleep after 5 minutes and it appears to be sleeping. The screen goes black but on closer inspection with a flash light, you can still see the login screen or any open window.
Here is a picture of what i'm experiencing http://www.flickr.com/photos/59070359@N04/5411570689/.
Can anyone confirm this problem by trying the steps below?
1.) Have the Apple 27 ACD connected to a 2010 Mac Pro with the latest Mac OS X update(10.6.6).
2.) Go into the Energy Saver and set the Display to sleep at 1 minute and have computer sleep set to never.
3.) Leave the System Preferences window open and wait for the display to sleep.
4.) Once you see that the display is asleep flash a light directly on the screen where you left the System Preferences window open.

I discovered this effect many weeks ago and just thought that's the way the display "sleeps". A possibly simpler way to reproduce the effect is to select a hot corner to put the display to sleep (using the Hot Corners... button in the Desktop & Screen Save preferences). Put the mouse in the selected hot corner to put the display to sleep and then shine the flashlight on the screen. You'll see an "echo" (? - pick a term of your choice) of whatever is on the screen at the time it's put to "sleep".
I don't normally use the hot corners feature since I quickly discovered I would sometimes move the mouse into there inadvertently and it was annoying when the screen blacked out. I don't consider this a "problem" though. After all how many folks shine flashlights at their ACD? I'm not sure what I was thinking to prompt me to ever do it in the first place.
I was once jokingly going to post about never shining flashlight at the ACD simply because you can then see every smudge and smear on the glass It would then start to drive you nuts trying to get 'em all off!
\[Heh, I guess now everyone reading this thread it now pulling out flashlights \]

Sleep problem with iMacs

I am happy owner of 2.8 GHz Intel iMac except with one nagging problem. When I leave my computer in the SLEEP mode for more than 24 hours it tends to not respond and WAKE when I return to use it. I have to unplug power and restart. Since I usually use my computer daily, it's not a major issue -- although it always makes me worry when I have any consistent issue with my computer
And it's not just me. I convinced my father and a close friend to purchase iMacs (PC users) last year as well. They have the same problem. It's worst for them because they are more casual users and often don't use their computers on a daily basis. They all have the exact same issues and are very unhappy about it. They both have the low end machines and have nothing but printers attached to them. I have done searches on the web and it seems like this issue happens occasionally, but it is not necessarily a common iMac issue. My experience is it's a problem with all of the iMacs (3 out of 3) we have purchased.
Anyone have any suggestions?

Here's something you can try:
Delete the following items in the /Library/Preferences/SystemConfiguration/ folder:
com.apple.PowerManagement.plist
com..apple.AutoWake.plist
Also delete the /Home/Library/Preferences/com.apple.systemuiserver.plist file
Reboot the computer.
If one or more of the above are not present, don't worry about it.
What if any third-party peripherals do you use besides the printer? Does this problem persist if the printer is not connected? What if any third-party software do you have installed on your computer?

Problems with ACD 20"

On July 21 I bought a 20" ACD from our local apple store, I got it home and hooked it up to find multiple stuck + dead pixels as well as a pink hue on the right side of the screen and a cyan hue on the left with a blue vertical band running down the screen left of center. I took it back and they exchanged it, I got home, hooked it up and this one had the exact same thing minus all the dead / stuck pixels. I took it back and they exchanged it, I got home and this 3rd one had the exact same thing minus the dead / stuck pixels. I took it back and they gave me a refund.
Today I went to an authorized apple reseller here and bought a 20" ACD hoping it came from a different batch, I got it home hooked it up and this one had the same thing except the vertical band was 3 times wider and right of center, plus the screen was crooked. I took that one back 20 minutes ago and they opened a new one for me to inspect before exchanging it and this one had the same problems. They seen the problems and refunded my money.
What is apples problem with quality control? Are they too focused on secondary products like the ipod and iphone? It seems their quality control with respect to displays is really horrible lately. All the gas and time spent on trying to get something decent from apple has been a real pain.

All of the ones I bought and had to return looked exactly like the problems described on this page:
http://www.dreamlight.com/insights/bugs/hd23.html
It's like the problems the 23" displays had except it was on all of the 20" displays I attempted to purchase over that period of one week. Every single one had horrible blue(ish) vertical band(s) either just left of center or in the case of two of the last ones I tried left of center AND the entire right side about 5 or 6 inches was also blue. Not to mention every single one of them had bad pink hues in the grays or shadows and it would not calibrate out, if you did try to calibrate the pinkish hue out that only made the blue bands more distinct. I felt bad taking all of those displays back since I honestly wanted one bad enough to make the 20 minute trip each way per monitor to keep trying to get one which worked. Extremely frustrating and VERY disappointing with respect to my loyalty to apple and playing the cinema display lottery... I still love apple but PLEASE work on quality control, I can't speak for everyone but I myself would be more than willing to pay a bit more for something which is held to a higher quality standard. Maybe move production OUT of China and to Europe or the USA? I ended up buying 2 samsung 21.6 inch 216BW displays for $100 less than the one 20" ACD and while the panel isn't a supposedly superior "s-ips" the things BOTH worked right out of the box with no blue bands or pink hues, a slight blue hue was present but that calibrated right out and not a single dead or stuck pixel on either one. I'm not a professional photographer or anything but I can't see a bit of difference between the ACD and the 2 samsungs when looking at a photograph. The gradients are good and colors are excellent.

Sleep problems with a MacBookPro6,2 with OSX 10.6.7

I have nothing plugged in my MacBookPro, other than the power cord.
I have tried all the tips I've seen, like resetting the PRAM and the SMC.
I even did a reinstall of the entire OS X (SnowLeopard 10.6.7) although I did recover all my apps and settings from TimeMachine.
It is really annoying and I am beginning to think there is some issue in the USB code within OSX's kernel.
The only thing I can think of I have not tried is not running Firefox, which is always open.
But I don't see how that might interfere with the usb hub on the motherboard issuing a wakeup.
I don't remember ever having this issue on my first generation MacBookPro.
All the info I've found is minimum a few months old, going back to a few years for problems with external hubs.
Does anyone know anything else to try? Is this the best way to make Apple know about the issue?

Solution found for me. From Adobe Acrobat & Reader 9.1 Release Notes:
Roaming Profiles on Windows and Networked Home Directory on Macintosh
are not supported configurations for 9.0 or 9.1, however we have made
several fixes in 9.1. We are looking at the possibility of supporting
this for the next major release.
As I am working with roaming profiles, my current solution (which is no solution at all) is to wipe current and reinstall Acrobat/Reader 8. Among other things there are supposed console hacks to make the purchased Adobe software run at all in a group work environment. I will end up trying them later.

MacBook Pro sleep problems with Vista SP1

Has anyone faced sleep problems on a MacBook Pro after installing Vista SP1?
I run Boot Camp 2.0 with the latest update from Apple.
IDT finally issued a compatible Vista driver for my Sigmatel audio.
I was very happy for the first time running Vista on my Apple when I had the stupid idea to upgrade to SP1.
After days of troubleshooting with Windows support it is obvious that SP1 and my MacBook Pro are incompatible for some obscure reasons. The latest time I tried SP1 was through Windows Update, which means that Windows detected no compatibility issues, such as drivers.
I suspect Apple-in-sight driver without any evidence, just a hint.
Any ideas?
Thanks

Hibernation seems iffy. Have you tried disabling hibernation? and when you say sleep, what happens? won't wake or what?
Normally I don't recommend resetting NVRAM or SMU but for sleep you might want to.
And yes, trying to rule out why can be difficult. But I would not blame SP1. Maybe BC 2.1.
Do you have a book dealing with Vista? or looked for articles or forums that deal with Vista? There is one for Vista64 - assume you have 32-bit though. Google is often best way to find things in Apple discussions or knowledge base, too.

Sleeping problem with OS X Lion?

I have a new 15 inch Macbook Pro that shipped with Lion which has recently succumbed to a sleeping problem. When I have the computer plugged in to the wall outlet for charging, and I close the lid, it goes to sleep, but the sleep light stays on solid; it does not blink/fade on and off. Then, under these same circumstances, when I open the lid, I see my login screen for about 1.5 seconds and then the screen goes black. If I click the F1 button to turn the screen brightness down, the login screen returns, and I can login and use the computer as normal with no issues. If I unplug the MagSafe charger and allow the computer to run on its battery, none of these issues occur.
AND all of the Energy Saver preferences are set to the default, and all sharing is disabled.
All help is sincerely appreciated,
Jake

I have the exact same issue! I'm so glad it isn't just me having this problem ..
I also have a 15 inch Macbook Pro with OSX Lion.
I really don't know whether it's a new feature of Lion or a bug.
Sleep mode seems to be disabled while charging ...
If you put the Macbook Pro to sleep with the magsafe adapter plugged in, it won't go to sleep. You can still hear the fans running, and the light won't blink, as you indicated. When you open the lid again, the screen lights up for a few seconds, then turns black. I haven't tried the F1 key, but I do know the screen comes back when you unplug the adapter ...
And it's getting even stranger: when you close the lid with the magsafe adapter plugged in, my MBP won't go to sleep. But when you plug out the adapter while still having the lid closed, my MBP WILL go to sleep. When you plug the adapter back in while sleeping, it will still keep asleep but the battery WON'T charge, although the adapter 's connected (the light is green while it should be orange, since the battery is not fully charged).
None of these issues occur when you put the MBP to sleep without the power adapter connected; it goes to sleep seamlessly.
It seems to me that this could be a bug, but it could also be an extra safety feature of apple ..
Maybe they wanted to protect the battery this way? I hear a lot of people say it's bad to keep for your battery to keep your laptop plugged in all time, although I doubt it.
Someone who knows more about this, or has a fix for this 'bug' ?

Sleep problem with iMac Duo Core

I purchased this 20" iMac Duo Core five days ago. Whenever the iMac enter sleep mode with pulsating indicator light below the screen, waking up the iMac always cause complete reboot of iMac. Is this a known issue with 20" iMac Core Duo or there is some problems in configuration under System Preferences ? The SMC firmware was updated from version 1.1f2 to 1.1f5 for installing Windows XP through Boot Camp Assistant in a NTFS disk partition.

Thank you for the useful lead. The problem has been resolved by executing System Management Controller (SMC) reset procedure outlined in support site. Further monitoring on behaviour of the SMC is required. Hopefully this power management problem is not as big as with first generation iMac G5 I used to own. No idea whether latest SMC firmware update released by Apple resolve this problem though I have applied the update for Windows installation through Boot Camp.

Heat and sleep problem with my new Macbook Pro

Basically I noticed with my new MBP the computer can become very hot and the fan gets very loud after about ~2 hours of working in Maya.. which I guess might be reasonable.
However, my main concern is, even when I close the lid of the MBP, the heat seems to stay (I just closed it for about 30 minutes, and it's still as hot as it was before I closed it).
I'm working on High Performance.. maybe my macbook isn't sleeping when I close it?
I have noticed (I THINK) that the white apple on the outside glows sometimes randomly even when I have the lid closed, but I'm not completely sure.
Anyone else have this problem?

Hi yes I've had/got the same problem. Received my new MacBook Pro only last week and this has happened twice. The machine gets so hot I can't even touch the battery area!!!! It only seems to happen with the power connected and when the lid is closed. Fortunately the Mac was on my wooden desk or it might have melted plastic!
The Mac cooled down after unplugging from power supply, but wow it was hot....and noisy!
The only way to get the Mac back was to either press the power/off until it shut down, or take the battery out - after it cooled down.
Reported the problem to Mac Support immediately, but no response.
THIS IS DANGEROUS!!! Be careful, I don't know what would happen if it was left overnight for example - could easily cause a FIRE!!!!!

Apple Cinema Display 24-inch sleep problems with MacBook 13-inch?

Hey guys,
Occasionally, my MacBook (13-inch, 2009) when connected to my Apple Cinema Display 24-inch screen will not wake up from sleep mode - whether in clamshell mode, or not. Even if i unplug the Display from the Macbook, the MacBook will not wake up.
This can be very frustrating when it occurs because i have no choice but to give the MacBook a hard shut down.
Not sure whether I'm the only one with this problem, but if there is any solution to this issue it'll be greatly appreciated.
Cheers!

You might try running the MacBook in Safe Mode for a while to see if the problem still occurs when running safe. If the problem goes away while in safe mode, that would point to a problem in the configuration of your main account.

Sleep problem with ext monitor

When the ext monitor is connected closing the lid causes does not put the computer to sleep, but into some kind of an unconscious mode (no pulsing light or fan), from which it won't wake. I have to push the PB for several secs and then wait a few more to push the PB again to reboot - usually successful. Any suggestions?

If you disconnect the external monitor, does the MacBook Pro act normally when it wakes from sleep?
Hook up the external monitor and try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart. For each disable/delete, you will need to restart if you don't do them all at once.

Macbook Pro sleep Problems with Time Machine and Time Capsule

I recently installed a time capsule as a Router and a Time Machine backup device for 2 macs in the house.
Unfortunately, I found that my 2011 macbook pro 15' updates the time machine backups even when the lid is closed and in sleep.
When I wake the macbook pro, it hangs and I have to reset the mac to restart.
This did not happen when I was using a firewire hard drive with the time machine.
My question is:
Is there a way to prevent the time machine to backup when the macbook pro is in sleep mode?
My mac is not equiped with power nap so it is not suppose to be doing this.
Thanks
Other info: OS Mountain Lion, regular hard drive, 8 Gig Memory

Edwin,
I assume that since the repair of the sparsebundle failed you still cannot open the sparsebundle in Finder and get the message:
The following backups could not be opened:
Imac of E.sparsebundle because there are no activatible filesystems
If the sparsebundle cannot be opened in Finder, then the chances that Time Machine can open them are nil in my opinion. Time Machine, in effect is just going to open the sparsebundle as Finder is attempting to dot, then it gives you a fnacy display, but the underlying issue with the sparesbundle is the same for both methods of access.
Do you, by chance hav a bootable backuo of your Snow Leopard system?
If so can you access the TM backups with it??
You didn't change the Time Capsules Network Password did you?? see this.
I looked to see if I could find anythng about the error codes you mentioned in your original post and so far can;t find anything about them.

Sleep problem with 30GB photo

I have a 30GB Photo, and if I let it sit like overnight, it goes into some sort of sleep mode. When you hit the button to turn it on, the silver apple on black background comes on and the hard drive spins up and when it finishes its killed off almost a 1/4 of my battery life.
Is there any way to disable this so that I wont have to charge this sucker so quickly?

What you are experiencing is sleep/deep sleep and there is no way to disable this.

If you are judging the battery life by using the icon, then wait a few minutes and you should find it returns to normal.

Macbookpro 08 not sleeping properly with safari 4.0.2 or 4.0.1 versions

Hi all,
Is anyone else having issues with their computer not sleeping as set in system preferences with these later versions of Safari installed? The computer sleeps sometimes, but lately it has been keeping awake more often than going to sleep as it is set to do. I would appreciate your feedback.
Thanks so much,
Tabeer

Hi
No sleep problem with my unibody MBP.
There may be Hard Drive directory corruption causing the errant behavior. Open Disk Utility, select your HD and "verify disk". Any errors? While there, "repair permissions" and restart the computer.

Intermittent Sleep problems on all Windows versions I have tried

Macbook Pro 5,1. Running Bootcamp 2.1. Machine will enter sleep mode successfully a few times (1-4 times) and then suddenly will not. Sleep light glows constantly and opening the lid shows a black screen.
Brightness controls work (can see the screen lightening) and volume keys work (here 'pop' noise increasing and decreasing).
I have tried Windows Vista 32/64 and Windows 7 32/64. I have installed updated drivers for NVidia card, Wireless Card, nForce drivers. I have tried disabling all the Apple services. I have made sure no devices are able to bring the machine out of sleep. I have ensured that the Windows Media Service cannot prevent the machine from going to sleep.
Apple support is (muffled scream) useless. All I get is that this is a Windows problem and not supported. (Why do they say that you can run Windows on the Macbook Pro advertisement then?). I have read a posts from other users with the same problem but none of them have resolutions.
Please help. It's the last step I need to make this thing usable. Can't return it, can't get it fixed. Can't get any help Apple and MS won't touch it. Otherwise, I'll swap this for a Dell of similar speed in a second. Any takers?

Never saw a Macbook Pro;
You Can Google search "Macbook PRO"Windows+sleepfix
Copy paste that into the search & Check various yourself
This one received positive response but seems on the Mac side.
http://www.gcsdblogs.org/roodhouse/?p=746
The fix for this problem can be found in the NETWORK panel of System Preferences. Click on the Ethernet Connection
If this service was already marked INACTIVE simply switch it back to MAKE SERVICE ACTIVE and then hit apply.
If it was already set to active then Click on MAKE SERVICE INACTIVE then hit apply.
Now restart your computer. After the restart go back to this same screen and click on MAKE SERVICE ACTIVE, now make sure to hit apply.
This will fix the sleep problems on a Macbook running 10.5.7. Interestingly it also fixes the sleep problems with a Macbook pro running 10.6 Snow leopard.

Just found that disabling the "wake-on sleep" option of my mouse, network and modem seems to fix the problem.
It may just be that my mouse or some other device tries to wake up the PC while it is going to sleep, and the computer gets all confused.
I've been using hibernate as well from the time I first got my macbook. It's really nice to be able to hibernate, boot into OS X, then shutdown OS X and resume the Windows session without having to go through the whole boot process. It's too bad hibernating OS X forces you to wake up in OS X and you can't choose which OS to resume.
Turning off AirPort usually will allow the MBP to sleep, but not always. In those cases, sometimes I have to try two or three times to put it to sleep -- and for whatever reason, it typically takes 30-60 seconds after disconnecting from the wireless connection before it will sleep. (And, yes, I have already disabled SafeSleep.)
For Windows side,from me: a)check all power settings that refer to sleep/disable, this includes doing it at device/adapter level; if you open network conections from C. Panel, right click active adapter(LocalAreaConn.), select properties,then configure "connect Using" you'll see variable power setting.You can see this variable setting in Device Manager as well.
