Monitor sleep question

I've just moved to a G5 from my G3. Temporarily I'm using the Sony trini tube from my G3 until I get an LCD.
With the G3, the trini passed thru and was powered by the G3. Sleep ran fine.
With the G5 (dualie 2G) it sleeps OK, but it is very slow to wake, like 30 secs. Any ideas? Will I face this same problem with an LCS?

bought an LCD. instant sleep or wake. guess the trini is getting weak.

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.

Possible to control monitor sleep via HDMI through receiver?

I've got the mid-2010 mini connected to a Pioneer VSX-1020 via HDMI, which is sending the signal to my Samsung LCD TV. I've noticed that the monitor sleep function is not working, and I would really like to do this for non-video needs.
There could be some power management issue that is beyond control of the mini since if I switch off the TV, the Pioneer switches off as well, but I was wondering if anyone else has noted and solved a similar issue.
FYI: For those looking to build a new HT system, the VSX-1020 is a fantastic feature/$ deal.

You cannot convert HDMI to VGA without some serious digital to analog conversion equipment. You cannot use a simple passthough device like you can do with a DVI-I to VGA cable adapter. You will need to use an HDMI cable and a monitor that has an HDMI or DVI-I/D connector.

Macbook Pro and external monitor sleep issues.

I recently upgraded to a new 13 inch MacBook Pro to replace my previous one. With the upgrade, I'm now on the latest OS and I have a Thunderbolt instead of Mini-displayport output. I have a Dell U2410 monitor which has worked great up until now, but I now have the following behavior:
When the laptop sleeps (or puts the display to sleep) the monitor begins to turn on and off. It goes to powersave mode and immediately wakes up, realizes there's no signal, and goes back to powersave mode, etc etc etc.
When I wake the computer up from sleep, the monitor's behavior stays the same. The laptop never detects the display and begins sending a signal.
If I unplug and replug the adapter, all is well.
There seem to be two separate issues: whatever signal the computer continues to send down the display cable after sleep seems to confuse my monitor, secondly, the computer never again sends a real video signal down the line after it wakes up.
I'm on the latest 10.8.3. My adapter is the same adapter I have been using for years, an apple mini-display port to DVI adapter. Supposedly this adapter is still compatible with the Thunderbolt port.
I've seen lots of issues online about wake up issues with the latest OS. Is there a workaround for this yet or do I have to uplug my monitor anytime I sleep the computer?

Hi Steve,
I have had the exact same issues after adding a WD Thunderbolt Duo external drive to a Mid 2011 iMac and then daisy chaining the Dell U2410 monitor off that.
My Mini DP to DVI cable ceased working properly - sleeps issues.
After buying one of these adapters of Ebay:
http://www.ebay.com.au/itm/3-in-1-Mini-Displayport-to-HDMI-with-audio-DVI-DP-ada pter-3in1-convertor-Macbook-/110861703462?pt=US_Audio_Cables_Adapters&hash=item1 9cfdf5926
I then tried all the different cables that came originally with the Dell U2410 with that adapter, and none of then would put the U2410 to sleep properly. The backlight would stay on, or "No Displayport Cable" would float around the Dell display with the backlighting still on. Or otherwise the Dell would try to go to sleep and then wake up again and cycle like you found.
Apples Mini DP to VGA adapter was sleep successful with the VGA cable (Analogue) but the output picture was not as sharp as DVI or Displayport, plus there was RF interference with the cable.
After lots of internet searching I have found a near perfect solution:
A HDMI to DVI cable with the HDMI end connected to the Ebay 3 in 1 adapter, which then connects to the Thunderbolt port.
Connect this to DVI-D 1 on the Dell U2410.
On the Dell in Menu - Other Settings, disable DDC/CI
Now in OSX Settings - energy Saver you will have to tick:
"Put Hard Disks to sleep where possible" and select a short time frame for "Computer Sleep"
I have found that the display would go black but the backlighting on the Dell U2410 would stay on, when the display went to sleep on the Mac as per the Energy Saver "Display Sleep" setting.
The backlighting on the Dell would only turn off when the time for 'Computer Sleep" has elapsed and the external Thunderbolt hard disk went to sleep as well.
The Dell U2410 would then wake up correctly as well when my iMac woke, with this setup.
Cheapest solution for you would be to try an Apple or Ebay HDMI to DVI adapter and then use the DVI - DVI cable that came with the Dell.
If that fails get the 3 in one Adapter and use my Mini DP/Thunderbolt to Ebay Adapter to DVI-DVI cable setup.
I'm assuming your new Macbook Pro comes with the HDMI port ?
I believe the Sleep Issues with this monitor are all related to appropriate signal on the cable, and only the HDMI to DVI solution will work correctly on Mac's connected to the Dell U2410.
Good Luck. :-)

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.

Monitor Compatibility Question

I plan on purchasing a Mac Pro with the Radeon X1900 XT card in the near future. I have been shopping around for a good monitor, and the Dell UltraSharp 2407WFP (found here: http://accessories.us.dell.com/sna/productdetail.aspx?c=us&l=en&s=dhs&cs=19&sku= 320-4335) caught my eye. However, at the bottom of the tech specs, it lists only PC under "Compatibility." I know of other people who have used Dell monitors for their Macs, and this monitor does have DVI, so I don't see why it would not be compatible with the Mac Pro. Does anyone know definitively whether or not this monitor would work?

Hello,
You should be just fine. The majority of monitors are listed as compatible with PC's only. The simple reason is that the manufacturers don't care to test them with Macs and have all their resources devoted to supporting what they know.
If they mentioned that it would work with a Mac, then they would be stuck trying to answer your questions on the phone if you needed help. Since they don't use Macs, and don't maintain a staff of Mac trained people, it is easier to just omit official support. That way they can just tell you that they don't support Macs and hang-up the phone.
I've been using PC monitors with my Macs since before Apple even supported PC monitors at all (you used to have to buy monitors with Apple specific cables). I would just use an adapter to convert the PC connector to connect to the Mac video port.
In all my years, I've never found a PC monitor that would not work with my Mac. And, that still holds true today. I've used several low-end monitors with my current machines, and all work fine.
I've even got a bargain basement DVI monitor connected right-now, and it works perfectly.
Basically, if you want official support and a guarantee, then buy a monitor that specifically lists Mac compatibility.
But, if you are willing to accept that their phone support will avoid helping you, then go with any brand you like.
Understand that Dell is primarily interested in selling and supporting Dell computers. They have no interest in fielding calls from Mac users because they are not going to be familiar with OS X. Naturally, they will list PC compatibility because they know Windows very well.
But, you should also understand that the only difference between an Intel-based Mac and an Windows PC, is that the Intel-based Mac can also run OS X. Otherwise, they are just different brands of computers that use pretty much the same hardware.
I hope this helps.

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.

Thunderbolt to monitor sleep issues

I have a MacBook Pro 13 inch late 2011 which I use with a Lacie thunderbolt drive. Putting the MBP and the drive to sleep is OK when I just close the lid. Using the menu and click sleep had an issue. So I always closed the lid of the laptop for sleep.
Now I have added a monitor with a cable from the thunderbolt drive to DisplayPort of the monitor. Everything seemed fine. But quite often the thunderbolt drive does not appear on my MBP on my desktop after sleep. It can be ok for hours, and then suddenly after getting it out of sleep after several hours the message appears 'drive not ejected correctly'. I have tried several combinations of putting the MBP and the rest to sleep, but after some time the same problem pops up again, the drive disappears from my desktop and I have to reboot the MBP.
I noticed that some people have similar issues with connecting a thunderbolt display.
It seems that the only way to have everything work normally is to shut down the MBP (which shuts down the drive and puts the monitor in energy saving mode). Then it's just a matter of powering the MBP up again and the drive and monitor will also become active.
But I'd like to have a safe sleep function back. Now the sleep function is having this issue of not correctly ejecting the thunderbolt drive. It works fine for a short time, then somewhat later this problem appears.

I have now connected my macbook pro to the monitor with a USB to VGA adapter. The monitor works fine, just as with the cable from MiniDisplayPort on the external thunderbolt drive to DisplayPort on the monitor. But the same problem exists in this case as well.
It is fine for an hour or so, the sleep function works normally. After wake all devices start up again. But after several hours of sleep it wakes up with the drive removed from the desktop and the message: drive not ejected properly.
It seems to be the same problem people have with a thunderbolt display. In my case it's the external drive that is ejected.
So, I guess it's a problem Apple will have to tackle.

Turning imac display off without putting it to sleep questions?

I like to leave my iMac on overnight but I don't want to put it to sleep COMPLETELY. Just to turn off the display. I heard you press control-shift-eject or do a hot spot on screensaver on system pref. But my question is, would it hurt the iMac in the long run for leaving it on overnight so much or it's made to last like that?
I talked to an apple specialist at the local apple store and he said these aluminum imacs are made to last even if you keep them on overnight? But would it overheat over the years? or I shouldn't worry so much. Sorry this is my first iMac. I have so many questions about it.

So it will not overheat no matter what?
If you are playing some 3D action game, or having the computer encode video for one hour straight, it may start to heat up. But then, the fans should kick up to a faster speed (you'll actually hear them), to keep the temp within the acceptable range. If the iMac is just sitting there, waiting for you to do something, it will not overheat. Now... If there is dust blocking airflow, or the Mac has some hardware issue that prevents the fans from running properly, then it is possible for a Mac to overheat, which may cause it to shut down unexpectedly or give you something called a +kernel panic+ (which is basically a system-level crash).
When a computer is running, for most users, it spends most of its time waiting for you to do something. If you are doing something simple like writing an email or web browsing, 90% of the time, it is waiting for you to do the next thing. If you have it doing something like ripping a music CD, during that time, it is working hard to finish as quickly as possible. But since most people do not rip CDs all day, most of the time, the Mac is coasting along, not working very hard. So, there is not much stress on the hardware most of the time it is turned on.
But if you shut down every night and start up every morning, one stressful time for the hardware is at startup. This is because all the components, such as the hard drive spinning up, display turning on, and the rest of the Mac are being powered up, happens at the same time. Waking from sleep is a similar process, and although it is not as bad as a full startup, it may happen much more frequently if the user is sleeping the Mac and waking it up frequently. That's why I suggested using sleep at the end of the day, to save power compared to keeping it ON, but once you have the Mac running at the start of the day, don't have it sleeping and waking numerous times throughout the day; just let it run until you are done for the day, then use sleep until the next day.

Mac Pro Monitor Sleeps

Hi
I have a new Mac Pro OSX v 10. 5. 5. If I select sleep and then later use keyboard the computor will wake but not the monitor. The only way I can awaken the monitor is to reboot. If I just leave the computor to put itself to sleep there is no problem as it will wake straight away when the keyboard is touched.
I have been advise to establish a new user account, removing all old accounts because it is suspected software has become corrupted.
Has anyone experienced this particular problem and how was it cured?

Do you really have OSX 10.5.5? Try updating to 10.5.8

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.

OS "Stutters" after screensaver/monitor sleep

I know this sounds incredibly odd, but just recently whenever I bring my mac out of a screen saver or if the monitor has gone to sleep, the entire system will stutter until I restart the system.
Even the harddrive will have noticeable "pauses" in spinning when retrieving information.
Has anyone encountered this or have a fix? I haven't added or changed anything recently on my system.

Welcome to Apple Discussions!
Are you sure it is happening when you are using only Screen Saver and not Energy Saver? I've seen this happen on Energy Saver alone. Screen Saver is activated by Apple menu -> System Preferences -> Desktop & Screen Saver. Energy Saver is activated by Apple menu -> System Preferences -> Energy Saver.

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.

If I look in Monitor > Fault Settings > Setup > Threshold Settings.
Then expand all groups under DFM, there is no group called "Tunnel", so the question is which group this Interface belongs to?
BR /Crille

Its defined as an 10/100 ethernet interface " Component Class Interface" with a 40% threshold utilization which it fell below per the event notifiation of 68.3%.

ICal and sleep question

if you have an iCal event that launches a script which will restart the computer at scheduled times, does that work if the computer is in sleep mode? or do you first need to wake up the computer with the option in the "energy save pref"?

Question withdrawn.
