Monitor sleep problems on G5/1.8DP

I have just purchased a new LaCie Photon19Vision TFT monitor and connected in to my G5/1.8DP and successfully set it up. My system is set to never sleep or use a screen saver.
For two days all was well and then, without any warning, I found that the monitor went into 'sleep' mode after ten minutes or so. I have deleted the usual preference files relating to energy saving etc, as suggested in the discussions, but this makes no difference. Whilst it is not the end of the world, it is a pain as the monitor is colour calibrated and takes time, albeit not too long, to return to its correct settings after waking. I have also got the same problem on a G4/450. This does not occur on my G5/1.6 or G3/400 though. The only common thread is that the G5/1.8 and G4/450 are each connected to their own dedicated UPS whilst the other two are not.
Does anyone have any bright ideas?

Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, then move these files to the Desktop.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
(Then Trash the original of these last two, as "moving" them only copies them.)
Test for problem in Safe Mode...
Reboot, test again.

Recent Windows 7 update causing monitor sleep problems/Windows loop in some HP desktops?

After perusing this forum, I wonder if there was a recent Windows 7 update that has been causing problems for some HP desktops and displays. My office has a 3500 Microtower desktop running Windows 7 Pro. While Windows 7 Pro is running and in use (as in, not prompted by any user-set power management option), the dual HP displays (via DVI split to VGA) will enter sleep mode ("No Signal", I believe) seemingly randomly/chaotically and without warning. No amount of mouse-waving and keyboard-smashing will wake the displays. The displays will not receive a signal after being turned off then on. Then, not immediately but after some undetermined time, the desktop hard drive light will begin to blink at a consistent 1-second interval (approximate), as though it is stuck in a loop.
My guess, based on both our office's experience and the posts I've read with the same problem (see below for links), is that this update would have become available either November 16 or 17, November 15 at the earliest.
Thank you for your attention to this conundrum!
Aaron
One more piece, not sure if relevant: a user connected remotely in order to monitor the desktop, but detected no problems with the machine. Unfortunately, I was not able to remain with the desktop to see if the displays had shut off at any point during his monitoring.

Dual monitor sleep problem

I have dual monitors and with 10.5.1 my second monitor will not open after it has gone to sleep. I have to shut down and start over. A simple restart will not bring it back up. I have never had this problem before. Any help??

Welcome to the Apple Forums.
In System Preferences (found under the Apple Menu in the menu bar), look at the Display pane to see if both screens are recognized by the system. Click on the Detect Displays button. This will force the system to connect to the monitor and will show you if there is an OS problem, or perhaps a hardware problem.
I keep the "Show displays in the menu bar" checked so that I can access it through the Display image in the Menu Bar at the top of the screen.
My experience is that different monitors have different capabilities of connection to the computer- some have to be "detected" every time; some connect, but have to be changed from a mirror to a span or repositioned in the arrangement pane; some just "work right"
Good luck. Joel.

Monitor Sleep Problem

I have a Hanns.G external monitor that no longer goes to energy saver mode (displays no signal input - check video cable) when I put my MacPro to sleep. This has been the case since I installed the MacOSX 10.6.3 update.
I've reset both the PRAM and SMC with no results.
Any ideas as to how I can fix this problem?

My system profiler lists the following for my monitor:
Hanns.G HG281:
Resolution: 1920 x 1200 @ 60 Hz
Pixel Depth: 32-Bit Color (ARGB8888)
Main Display: Yes
Mirror: Off
Online: Yes
Rotation: Supported
Television: Yes
There are several preference settings on the monitor itself, but nothing on the computer. There is only 1 HDMI slot and I have disconnected, reconnected it and the power cord several times. None of the monitor settings indicate a "sleep setting".
I've been quite happy with the monitor. I upgraded from a smaller Apple Cinema Display and noticed no difference in quality. My printer output with my Canon Pro 9000 shows no differences between output using my Apple monitor and that of the Hanns-G.

Possible reason for the iMac G5 with 10.4.3 Sleep Problems

Ok first off let me say that I got this new iMac G5 20" about 4 days ago. It's wonderful. If anyone out there is holding out for the intel machines, don't wait, get a G5. It's a fantastic machine. Now on to the meat of the subject. The story goes like this; I hooked up my Plextor PVR with eyeTV to my iMac to see how well it would do (been using it with a P4 Windoze XP machine and my iBook G4 14" with no problems). It worked just great. No problems with the iMac, the PVR or any of my other addons (including the boatload of software I migrated over from the iBook). So I set up EyeTV to record some stuff while I was asleep. It's supposed to wake up the Mac, record the shows then the Mac goes back to sleep. Easy huh? Well the wakeup, record part went just fine but the Mac wouldn't go back to sleep. Perplexed (actually thrilled, this is where I have my most fun with new machines, figuring out why they aren't working correctly) I did all the standard "I can't get my Mac to sleep automatically" things. You know, blow away all the plist files that have anything to do with powermanagement and autowake, reset NVRAM from OF, reset the PRAM (3 times just like the old days), reset the SMU, blow away all the Bluetooth plist files, etc, etc. Did them all, don't suggest any, I did them all I swear, really. I've been through this kind of thing before. One big difference with this iMac. Nothing and I mean nothing would work to fix the problem. The only way the bad boy would sleep is by hitting the Power button for a second or selecting "Sleep" from the Apple menu. Hmmmm. Spent the better part of a morning reading every thread here about peoples problems like mine. One post and I mean exactly one had something I hadn't tried. I rebooted the Mac in Safe Mode (hold the shift key down while it boots until you get the login screen with the red text "Safe Mode".) I forgot that OSX even did that. Logged in as myself (normal login but still in safe mode) and low and behold the thing would sleep automatically! I repeated this (boot in normal mode, boot in safe mode) many times. Every single time the Mac would sleep from safe mode but not from normal mode. Tells me it's software not hardware. In each mode I run "Activity Monitor" and save a list of the running processes to a text file. Now compare them and shutdown each process that is different one at a time. To make this story somewhat shorter (heh) I finally found that I could consistantly make the machine sleep or not sleep by killing the "mdimport" process and restarting it. This has to do with Spotlight. To be exact, it's the process that imports Metadata into Spotlights data list (I'm no expert, have a basic understanding of this). So on a hunch I ran the terminal and entered the command to delete then rebuild Spotlights databases, "mdutil -E /". Then I let Spotlight rebuild that databases and rebooted. Guess what? The iMac sleeps perfectly now, go figure. I did this once so far and the Mac has been working correctly now for about 5 hours. I've got a feeling that the problem will come back. Especially if it's an inherent problem in Spotlight and the 10.4.3 upgrade. I don't seem to have this problem with 10.4 or earlier. Long post I know but I thought it could help someone out. Please post any comments. I'd like to know if what I did is coincidence (I really don't think so since I reproduced it many times) or not.

iBook G4 1Gig, iMac G5 2.1 Gig, iMac 266 Mac OS X (10.4.3) iMac 266 running 10.3.6, been using Macs since the '80s

Right guy's i to have researched this problem
concerning my auto sleep problem.I started off by
following Joeaux's original post by safe
booting,noting what was running in the activity
monitor,booting normaly and again noting what was
running now.I eliminated the same processes that were
running from both boots, and then started quiting one
by one, the extra processes, from the normal boot, in
activity monitor.Once you quit a process, allow the
computer to try to go to sleep i.e set energy saver
to 1minute and wait to see what happens.I tried the "
mdimport"as of Joeaux but this was not my problem.In
my case the sleep problem was down to two
applications called N67U_ButtonManager and
N124U_ButtonManager.These are for use with my Canon
scanner.I also noted that if i left the scanner
connected to the computer this would also stop it
going to sleep,even after deleting the two
applications.Hope this helps!
Thank you now i know that those login items are for my scanner, and not logic audio i am a little less angry(Logic is now an apple application but the version I run was from the emagic days and i presumed that the button managers were from this app as it was the oldest bit of software running on my machine) By the way any apps that may cause a problem like this are more than likely simply residing in your user login items and can be disabled from there permanently as far as i can see.

No screensaver and monitor sleep mode

Hello guys,
I have the following problem with my Mac Pro (Early 08) and MacBook Pro 2.33 GHz. Both are Mac OS X 10.5.4.
I have installed the latest Security Update 2008-005. After installation both computers have similar problem with Screensaver and display sleep mode. Both simple don't start. I mean that my laptop and desktop computer don't start screensaver and after some time they don't turn off attached monitor (respectively built-in display).
I also tried to change time of both things (screensaver time and "monitor sleeping mode" time) to different time. I also restarted both computers few times already.
My laptop seems working after these "changes and restarts", but Mac Pro doesn't. Monitor is always on.
Please, do you have any info regarding this? I am quite possitive it was caused by mentioned security update, since before that update, both worked perfectly.
Thank you for any help.

Welcome to Apple Discussions.
Create a new account, name it "test" and see how your monitor and screensaver work in that User acct? (That will tell if your problem is systemwide or limited to your User acct.) This account is just for test, do nothing further with it.
Open System Preferences >> Accounts >> "+" make it an admin account.
If the problem is present in the test account also, then it is systemwide. In this case try repairing this with the 10.5.4 Combo Update . This is a fuller install, as opposed to an incremental "delta" update so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before.
Remember to Verify Disk before update and repair permissions after update from /Applications/Utilities/Disk Utility.
If the problem does not appear in the test account try starting in "Safe Mode" (It will take a bit more time to startup because it runs a directory check first).
If that works go to System Preferences >> Accounts >> Login Items and remove them. Boot normally and test. If there are still problems, go to ~(yourHome)/Library/Contextual Menu Items and move whatever is there to the desktop. Then do the same with /Library/Contextual Menu Items. Lastly, try moving /Users/Home)/Library/Fonts to your desktop and restarting.
Log out/in or restart, if that sorts it start putting items back one at a time until you find the culprit.
Let us know.

Dual 2.3 Power Mac G5 sleeping problem

For sometime now my G5 has had a sleeping problem. I use evetv 500 to record tv shows. Most times I have been on the computer say 5 to 6 pm. I'll have it set to record at 7. The G5 will start up and record no problem, but the monitor will not go back to sleep, the whole system is almost locked up . I have found that the computer clock will be stuck at the time I let it sleep. If I move the mouse the clock will update, and the system will sleep.
Thanks for any help
Dual 2.3 G5 PowerMac Mac OS X (10.4.9)

Hi,
I've experienced something similar a bit now and then. The most recent occurense of this was just a few minutes ago. Last thursday (june 21st), I set my Mac to record one show at 21.00 and one recording at 18.00 (every weekday on the 18.00 one), both recordings are one hour each. The ordinary "sleep when idle" function doesnt seem to work properly but I still set it at 15 minutes plus a scheduled sleep at 22.08. Now when just I came home the Mac was on though it shouldnt be. iStat in Dashboard gave me these figures:
Uptime 0d 4h 22min, up since 8.35 june 21
The only reaction I got when I tried to check the sleepsettings was a message telling me that the computer was scheduled to go to sleep in 9mins 55sec's and the System Preferences panel just bounced in the dock, every app that I tried to start just bounced in the dock. When I tried to restart it I got a message, after a while, telling me that Eyetv was keeping my Mac from going to sleep and trying to force quit it didn't seem to make much change. I finally turned the Mac off by pressing the powerbutton on the front.
I got the 18.00 recording on thursday but not on friday and no 21.00 recording from thursday. I thought the scheduled sleep would override the other setting...

Manual Sleep Problem

Occasionally, when I try to put my G5 to sleep manually, it won't go to sleep. I always make sure that all powered peripherals are unplugged. And then the problem goes away after restarting. But the the manual sleep problem returns within a week or so. I prefer to keep my Energy Saver on "Never Sleep" because I run Pro Tools on my machine and it doesn't support sleep mode.
Has anyone else had this problem?
Thanks

David Penick1-
From your description it is most likely one of the externally attached devices.
The USB and FW hubs built in to the Apple monitors have a habit of causing this problem. I would disconnect those hubs first and see what happens.
It may be one of the drives as well.
I would suggest disconnecting all external peripherals except keyboard and mouse and see if the problem goes away. If it does, keep adding devices one at a time until you discover which one is causing the problem.

Idle sleep problems

Apologies I know there have been 1000's of posts about this but I think I have been through all of them and I cannot workout why my iMac will not sleep when idle.
I've tried SMC re-sets, PMU re-sets, I've setup a clean user, run in safe mode, disconnected every peripheral and still it will not sleep when left idle.
I've even been to the extent of writing a load of IOKit based code to hook in callbacks to the power notifications from the kernel and I never see anything.
Just to be clear, if I tell the machine to sleep from the Apple menu it does and it stays in sleep mode until I wake it.
I think this started after 10.6.4 came out but I cannot be sure.
Any help would be greatly appreciated.
Cheers,
Steve

Steve,
Thanks for the reply!
That's some good info in the KB...but info that I've tried, except 'new user acct'. My problem is it's intermittent. EG, upon auto wake this morning it din go to sleep after 10 mins, per default setting. I did have an iCal 'reminder' on the screen, but that shouldn't be the culprit as I've had auto-sleep occur even with a reminder on the desktop. I responded to the reminder, opened A.Monitor and went and got a cup of coffee....etc. When I came back in about 12-13 mins the puter was asleep! (BTW, I've not had any problems with monitor sleep) Yesterday it was not auto-sleeping and I did an SMC reset, and it worked fine the rest of the day...until this moring.
So, it's intermittent. What I see persistently in A.Monitor is Dock and Dashboard Client. Could something like WeatherBug widget be the culprit? That's my main question: how to know which process out of many is the culprit; I mean I have a pretty long list of processes.
I guess I'll quit those 3-4 processes (Dock and WeatherBug) the next time I have the problem and see if that helps. And, I'll try the new user acct approach.
Thanks again,
Cheers to you too
Dave

Lion sleep problem

Hi folks,
I read all messages on the Lion sleep problem, verified all relevant settings, and tried all that was recommended and applicable, but to no avail. The display goes to sleep as set in energy saver but not the disk. Does anyone has more to offer on this subject? And apropos SleepPlease: I in principle refuse to download software that puts the machine to sleep when it's supposed to do so on it's own. Any help is appreciated.
Best
Frank

I tried both of those suggestions an am still having the problem. My settings are set to sleep the display and the monitor after 10 minutes. Most times it wakes up fine, but it seems that since the update it does not wake up after being asleep for a considerable amount of time.... I have to do a hard reset to get it to come back up.

New computer, still having SLEEP problems... aarrghh!

I just switched from my PPC 2x1.25G4 MDD to the new MacPro 2x3.2... and i'm still having sleep issues!
And this was before I even migrated over my system (which I did manually). I played around on my new, virgin system... and sleep was all wonky!
My previous problems w/ the G4 started right after the 10.5.2 update. I could GO to sleep, and wake up, but my monitor wouldn't come back on! Also, my USB and firewire would stop responding unless I did a reset.
Now, it's very similar. I can go to sleep, but when I hit the space bar, or click the mouse to wake up, the MacPro's fan starts WHIIRRING very loudly... and, more often than not, I get a grey screen with an apple, and the "progress gear wheel", which means the computer is starting up!
Again, I have NOT migrated all my old stuff over. Just very specific apps, and user info.
So what's going on? I've searched these forums and elsewhere, and sleep problems are very common w/ Leopard.
Any ideas?
e

Two of the most common causes for sleep issues are peripherals that aren't known to be compatible with Energy Saver, and peripherals that are underpowered plugged into the displays which aren't always able to give those peripherals sufficient power. As for fan issues, some people are more sensitive to fan noise than others, but some fan noise is normal, while others are not. Find an authorized service center that has a quiet room where they can investigate whether the noise is normal, or is willing to make a house call to determine it. I would not ask someone who has been sitting in the noise filled Apple Store to diagnose if the noise is normal.

15" AL PB G4 Sleep Problems

Another in the long list of sleep problems. Running the latest & greatest Tiger and all that. I have read and read and READ! the discussions and followed most of the advise to no avail. Here's what's up.
When I try to put the PB to sleep, either by closing the lid or through apple menu, everything starts out ok. Screen goes dark, LED comes on, Great! At the moment when the LED becomes brightest, the Superdrive makes a noise like it is cycling, and the PB wakes up. If I leave the lid closed it continues this indefinitely. If the lid is up, it wakes and the srceen flashes from desktop to black a couple of times the seems ok.
When I open the lid after experiencing this behavior I can hear the machine wake, but screen stays black. Must turn off by holding down power button, then start up again and all is fine.
Any one else experiencing this drive cycling?
Thanx,
Chris

Unresponsive Keyboard and Trackpad problem AT STARTUP + Sleep problem

When I turn on my computer it boots the OS and everything works except for the trackpad and the keyboard. I wait for about 5-7 minutes and then the trackpad and the keyboard start working.
Additional problems:
If I try to sleep my computer, the screen turns off, but the computer never stops working, so I have to force it to shut down.
Temporal Solutions
1) Boot in safe mode, it solves the trackpad/keyboard problems but not the Sleeping problem
Attempted fixes
1) Conencted external keyboard mouse/keyboard. Doesn't work
2) Reset the battery controller.
3) Reinstalled 10.6
4) Installed 10.5
5) Installed 10.6.3
Known Stuff:
1) The trackpad/keyboard are always connected as I can move the mouse and use some gestures with the Better Touch Tool app, and the keyboard works because if I click the Caps Lock key, the small led turns on.
2) Also, I have the HardwareGrowler app which tells me if hardware gets connected or disconnected and it never tells me anything about the trackpad/keyboard getting disconnected.
3) The OS is working at startup because apps show stuff and get updated and I can still get growl notifications.
NOTE: This is an intermittent problem, about 1 out of 10 times I turn on the computer I GET the problem.
Thanks a lot!

I came across a similar issue as the original poster. My trackpad and keyboard are unresponsive for 5 - 7 minutes after startup. I've updated my OS to 10.6.4 twice and it's still happening. I recognized this behavior after the Preferences->Network pane froze while I was trying to remove a VPN setting. Removing /Library/Preferences/SystemConfigurations did not help the problem.
Do any of you have advice on debugging the issue?

Power Mac G4 sleep problem

Hello!
My G4 (mdd) won't go to sleep anymore. Neither on its own via energy saver nor when you press the power button or select sleep in the apple menu. Does anyone know what to do?
I already unplugged my USB devices, didn't help. Then I trashed my energy saver and bluetooth preferences and reset PRAM by pressing <commandoption+PR> at startup, no luck. I read all the previous posts about this issue and did everything they said, but it didn't help.
maybe someone has an additional suggestion.
Thank you!

Power Mac G4 (mdd) 867 dual Mac OS X (10.4.3)

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 10.3.9 combo update. Others here would use the one for their version.
Cheers!

Wierd monitor compatibility problem

Hi all,
Got a wierd monitor compatibility problem. G3 works fine on a sony 21" CRT.
Connected it to a Daytec 15" CRT which works fine with a windows 98 PC.
With the G3 I get the apple and the spinning up logo then the screen just goes blank.
Is this monitor PC only or something? It is an old monitor but I thought any monitor should work
if the vga connector fits?

So you are using this directly plugged into the stock Display card in a Blue & White G3 with NO adapter?
The Mac is probably still set for a higher resolution that the SONY can do, and has not noticed the display has changed.
Video pros says that Video can be plugged and unplugged all day long with no bad effects. If your old display is still around, try setting it to 640 by 480, save changes, and swap the other one in "live" at that resolution.
Other tricks:
Reset the PRAM. This will send you back to a default setting while booting up, but may change when the system becomes active.
Boot from a CD. This ignores the settings on your Hard drive, and boots to a very simple resolution like 640 by 480 to ensure that Most Macs can start up with it.
